Hi, young man, very good video. I am a retired chief marine engineer. I remember some times in 1977 when i joined as a junior engineer ( 5th engineer) in a oil tanker. Since it was a coastal tanker, the sea chest was cleaned once a month. I was assisting the 3 rd engineer along with a fitter and 2 crew members. No anti fouling system those days. A vent valve was provided to remove air after boxing up the filter. I was told to apply grease on nuts and bolts after cleaning before bolting back, so next time removal will be easy. No rust formation. Those days we cant go inside. After cleaning we inspect visually. May renew rubber sealing 3 mm thick if necessary. Thanks for rekindling my memories. I am 69 years old. God bless you.
Hi Chief! What an amazing feeling it is to receive a comment from you, thank you. Most of what you were told to do during the sea chest job are still the practice today. Thank you for sharing your experience and I am glad this video brought back fond memories of your younger sailor days. Once a sailor, always a sailor 👍 Please do subscribe to my RUclips channel
Thanks a lot Ajmal! Do share it with your friends and colleagues and let me know if there is any particular topic which you would like to be covered in future. Thanks 👍
Thank you so very much for your kind words! I am not a teacher but I made this video in a way as if I was explaining to trainee cadets/students and now when you tell me that you (an actual teacher) find the video worthy enough to be used for explaining your students, it is really a huge compliment! Thank you so much! And in case there are any other topics from ship/machines that you would like covered for the benefit of your students, please do let me know and I will try my best to help out as well.

Miracle of RUclips... I'm not a sailor... I'm not a mechanic... But I'm curious. And you gave me a part of knowledge. Miracle too : I'm french, my english is a bit insufficient to understand all that you said, even if your pronociationis good for me, but the subtitles came to enforce my efforts. Thank you. I whist you a good sea.
Andre, Merci beaucoup pour votre merveilleux commentaire avec de si beaux mots d'encouragement! Je suis heureux de savoir que vous avez trouvé la vidéo utile. J'ai de l'expérience sur des navires travaillant avec différentes nationalités, certains qui parlent très bien anglais, d'autres qui ont besoin de peu d'aide. Il est important que tout le monde se comprenne au travail pour éviter tout accident. De même, je passe souvent quelques heures supplémentaires à ajouter des sous-titres à mes vidéos afin que même si quelqu'un n'a pas confiance en l'anglais, il puisse toujours regarder et comprendre à partir des sous-titres s'il le souhaite. Votre commentaire m'a fait très plaisir car je suis content que mon effort supplémentaire pour mettre des sous-titres montre un résultat :) Je ne parle pas le français, je tape ceci sur google translate. Merci pour vos voeux et bonne journée ! 👍 Thanks a lot for your wonderful comment with such nice words of encouragement! I am happy to know that you found the video helpful. I have experience from ship working with different nationalities, some who speak very good English, some who need little help. It is important that everyone understand each other at work to avoid any accidents. Likewise, I am often spending few extra hours to add subtitles to my videos so that even if someone doesn't feel confident about English, they can still watch and understand from subtitles if they want to. Your comment made me very happy because I am glad my extra effort to put subtitles show some result :) I don't know French, I am typing this on google translate. Thanks for your wishes and have a nice day! 👍
you know, I use Google translate too. my challenge is to write in english, and to watch if I use the rights words or not. More words comes to my practice. Step by step, my understanding progress. And I'm able to have a conversation with you today. To be noted, the french text you wrote is perfect ! Have a nice day.
Actually vessels normally have a high sea chest, which is used to in shallow water to reduce intake of sediment, and low sea chest could be used when navigating in ice- covered water(when the ship is rolling to avoid losing suction..
Rahul... your video is amazing.....Keep posting. U know sharing knowledge increases the your knowledge. the best thing in the life is sharing... that too knowledge, which is great among all..
Thanks a lot Prakash for the kinda words and your positive feedback about the video :) i will try to be more regular with posting engineering videos, do subscribe to my RUclips channel 👍
When ship is at anchored at port, the depth of sea bottom is low that is why we use High sea cheast. Because low sea cheast will suck mud. When sailing, when the sea surface is deep, we use low sea chest suction.
Neo, well said. The under keel clearance is definitely one of the reasons. I hope you found the video informative. Do subscribe to my RUclips channel 👍
Sir, thank you very much for the time you took to do this video for us. It was very entertaining and educational for us landlubbers! I wanted to ask you if you have ever heard of a vessel sinking because one of the sea chest gaskets (seals) or intake grates leaked? Also what brought me to your video was an episode of Australia 60-minutes. It was about how the drug cartels are actually smuggling their narcotics by putting them in the sea chests and the Australian police and customs officials are now using robotic video equipment to detect this. Very interesting indeed?
Hi Thomas! Thanks for your comment, I'm glad you enjoyed watching the video as much as I enjoyed making it. Coming to your question: Yes, flooding (and even sinking) is one of the main dangers while carrying out the sea chest cleaning. There have been ships in the past which have totally sunk due to the gasket seal or the valve seat failure. One if the points mentioned in the "Job Checklist" is that the area where cleaning is ongoing should never be left unattended (example - people worked on this for a few hrs and then went for a coffee or lunch break). Personally when I was getting this job done with my team, I would also start and then finish the job and give the team an early break or even a longer break at the end and everyone was happy. Regarding drug smuggling, well, the cartels are very very creative aren't they? I don't have any first hand experience but yes, they do try to smuggle stuff in the sea chest, underground part of the hull, bow thruster tunnel and what not... Do SUBSCRIBE for more such videos. Have a good one!
Hi Melaku! Thanks a lot for appreciating the video 👍 also, your comment duly noted, I will try to upload videos on those topics in future as well. Please do subscribe to my RUclips channel 👍
Is it possible you can ask the Chief Engineer about this and tell me what he said, because in this moment I have no idea why wouldn’t this be done on any Foreign going ship trading Worldwide

Thanks for such a nice explanation, non-marine guy like me also can understand and feel the environment ... Keep it up, looking more knowledgeable sessions from you. Thanks. A dumb question:: what is the need of pulling Sea water inside the ship, is it only for cooling purpose or there is more use?
Thanks a lot Praveen! Means a lot, your feedback and the nice words of appreciation! Really, thanks a lot! :) To answer your question: previously (30 years ago) most of the ship systems were Sea Water cooled, but due to sea water (salt) the piping, machinary etc will corrode faster and also will clog up faster during normal operation. Thus, at some point, the cooling system was changed to Fresh water cooled i.e. Sea Water comes in, cools the fresh water (already available onboard) and then the Sea water goes overboard while the Fresh Water s circulated and cools all the other systems. But overall, Sea water is just for cooling the Fresh water. Hope this answers :) Thanks a lot for your support with the channel!
We been together on Monte Cervantes last 2021 when your are second engineer that time. You are a good man second thank you for the knowledge and advices. 🫡🙌
Excelent video. Congratulations. I work in customs and border patrol in my country. Unfortunatley, we are having to much problems with drugs placed in the sea chest. The drugs usually are placed inside the sea chest and tied on the external grid. Criminal divers do this. I am not a mechanic engineer, but i am an eletric engineer. I have to ask you something: Is there any way we can insert a small camera on the sea chest, by inside the ship? Is there any inspection window on the sea chest for the mecanics make a boroscopy? Another question: if the bags with drugs are placed in the sea chest, next to grid, can we look on the machines eletronic control and detect a water pressure (or flow) change? Thanks
Hi Diego, thanks for the nice comment and your words of appreciation. If you want then do Subscribe to my Channel, it helps. Coming to your questions: About camera on sea chest - The sea chest is always pressurized with sea water from the overboard side. Inserting a camera would mean to find an opening on the sea chest from inside the Engine room to insert the camera. There are openings available, but personally I think no Chief Engineer or Master would allow it as it means a lot of extra job for the Crew (Isolating the sea chest, draining some of all of the sea water content to de-pressurize the sea chest, removing the mountings/flanges on top of the sea chest to facilitate the camera insertion etc...AND these mountings are not so big, so, the camera will also need to be really small (smaller than GoPro)...so, overall, I am not sure how feasible this is. Additionally, you might just be able to insert the camera but you have no control over the movement of the camera, so, you can really see everything. Moreover, the grill area which you're talking about where the drugs are usually installed, are still more to the outside of the sea chest and a camera inside sea chest still won't give access to the grill sections (because the isolative valves are just before and after the sea chest while the grill etc is closer to the sea side (before the overboard isolating valve) and that area cannot be isolated (unless divers are employed and they blank the sea side using plates). Hope this answers the first questions. Next question about the flow change detection: There are pressure sensors installed on the sea water side (we need to know these values as well to monitor the running parameters, to monitor cooling efficiency or to detect ice when water temperature is really low during winter). The sensitivity of the instruments installed is not that amazing to detect a flow change due to some (or more) amount of drugs. I think if the entire sea chest area was filled with drugs, and the Sea water pumps were starved of sea water, so much so that there is really a drop in pressure, only then will it really show a pressure difference. Otherwise, I think these instruments will not be able to give you any signification data which can be used to detect drugs on the sea chest. Another thing - the pressure shown on the pressure gauge or on the remote monitoring system is the instantaneous Sea Water Pressure in the moment. The value also depends on how is the ship loaded with cargo (more cargo = more sinkage = more draught = ship is deeper into water = more pressure available (since pressure increases with depth). So, this would further make it complex for you to really determine if the pressure difference is due to drugs or due to cargo loading or due to ballast (different topic but ships can also take in sea water in dedicated tanks to increase/decrease their draught as required for stability reasons depending on cargo load distribution and navigational requirements. Hope this answers the second questions. Let me know if you have any other questions and I'll be happy to help you. Have a nice day!
@@RoamerRealm Thank you for all your wonderful explanation. The idea of trying to insert the camera inside the ship came about because here, in the port, the water is very dark. Almost impossible to see the ship's hullI using a ROV (Remote Operated Vehicle). We already tried the ROV. About the pumps, i thought that the drug packages could cause a drop in the pump pressure. But, as you said, it would have to be a large amount of drugs. Another ideia came these days, about the sea chest cathodic protection system. I thought about whether the use of plastic to package drugs could disrupt the conductivity of the sea chest cathodic protection system (plastic is insulating) . Maybe the plastic use can make the controler of cathodic protection system use more current. Do you think you would have the sensitivity to detect it? Thanks
@diegoperes2287 You are welcome, happy to help you. Below are my thoughts about your latest comment: If the water in the port is extremely dark, maybe a long term solution could be to use a dredger to clear out the sediments/underground marine growth in the port. If there is not enough UKC (under keel clearance) then these boats while arriving in the port stir up a lot of dirt/sediments and underwater visibility is further hindered. If allowed some time, these disturbed sediments settle again and maybe the visibility is better after sometime Vs when the ship has just arrived and Tugs are working along with Bow/Stern thrusters. So, if possible, you can plan the inspection of the ships accordingly or employ a dredger and deepen/widen/clean up the bottom bed of the port. About the ICCP (Impressed current cathodic protection), this is a dynamic system and measures the instantaneous potential difference between the hull and the reference anodes. Ships hull surface area is huge compared to the small area on which the plastic/drugs are going to be stuck. The instrument might catch it but due to the small area, it will auto apply the corrective current to the system to compensate for the change in potential thinking that maybe some paint has peeled off or there is higher marine growth or maybe even a slight change in the density of water. This system can give usable indicators only when ship had a grounding or touched bottom and a large part of paint got peeled off or when ship went from sea water to fresh water (density change)….other than that this won’t give any meaningful difference in measured values as the system will automatically correct and supply the right current to the hull. Hope this answers the question. Let me know…
@@RoamerRealm Thank you my friend. All your tips and explanations were very valuable. The opinion of someone who has technical knowledge about mechanical engineering is very important. A thank you from Brazil, port of Santos
@@diegoperes2287Muchos gracias amigo! I have been to Santos a few times and made some wonderful experiences staying in the city, exploring the city and also meeting some very nice people (we met more than 10 yrs ago but some of them are still my friends) Brazil has always been very special, I am from India and I feel our cultures are also very similar :) thanks for the kind words and have a great day!
Hi Ashish! Tricky situation…hard to give a straight forward answer. How bad is the leak? There is a drain valve on the sea chest which drains to the bilge well. If the rate of leak is very very low and you can keep the drain valve open and see that the pressure on the chest drops, then you can give it a shot by keeping the drain valve open while it drains to the bilge well while you try to clean the strainer BUT this is very very risky. I think the best way would be to bring this up with Chief Engineer and vessel superintendent and carry out a risk assessment. Maybe it could be possible to block the sea chest outlet using magnet/divers from the outside OR if the vessel is soon due for dry dock then it can be fixed properly during that time.

First of all I want to say your video was amazing and super helpful. I just finished my first year of school for marine engineering and I am working on a ferry boat as a cadet, but yeah I want to say the video was great and being able to see how your systems are the same but different at the same time was very helpful. Also the fact that you answer all the comments and questions is awesome and very informative. I just have one question the guys on my boat call the tank right after the sea chest a sea bay and I’m pretty sure it does the same thing as the mgps but I wanted to make sure so can you let me know if that’s a different thing or just a different name.
Hi Deni! Thanks a lot for your comment and thr nice words about the video, I am glad you find it informative nad helpful 👍 Coming to your question, sorry, but I am not familiar with that word "sea bay" with reference to the sea water system. It could also be something ship type specific, and since yours is a ferry and mine a container, maybe that's why I don't know that term. Nonetheless, if you could send me a pic (as an Instagram DM) of the piping system, I will have a look and try to figure out what is the function of the sea bay. Let me know and do Subscribe to my RUclips channel 👍
@@RoamerRealm yea sure, will subscribe. Yes I do watch ship related videos. But i am mostly into deck videos as self is chief officer. Today was looking into ballast water pump filter cleaning related videos and found urs. Watched it and liked the same because of simplicity in explaining.
Thanks a lot, I take that ("simplicity in explaining") as a big compliment 👍 Hmm, about the ballast pump filter, just to be sure, you are looking for the line filter OR the filter on the ballast water treatment system? Let me know, I can try to help you out if that's ok with you..have a safe sail 👍
@@RoamerRealm Actually looking for both. But majorly line filter. I wanted to know what is the correct procedure for going ahead with line filter job if there is any.
Ok, I understand, here is for the line filter: you need to isolate and de-pressurize before opening, so, look for the valves before the filter (on the suction side) and after the pump (on the discharge side) (Usual arrangement is - piping-> filter->pump) to isolate the filter. The valves are usually butterfly type, make sure they are tightly shut. Open the vent on the filter and de-pressurize the isolated line. If the water is not stopping, it means that the valve is not holding. So, only proceed with opening the lid of the filter once sure that no more water is coming out. After this will be the usual filter cleaning and then assembly in reverse sequence. Once all assembled, open Sea to Sea, check for leaks, and close the filter vent when all air is purged out and only water is coming from there. That's it I think, system can be put back to normal after that. Let me know if you have any other questions 👍
First, great video. So, about block valves on Sea Chest. I usually see a manual butterfly valve and an hydraulic butterfly valve (with handwheel). Why the hydraulic valve is used, insted of another manual one?
Thanks a lot Bernardo for your nice feedback! Coming to your question, I have actually sailed on ships which didn't have a hydraulic valve at all - yes, that's right, there were just 2 pieces manual valves i.e. before and after the sea chest (also known as the overboard sea chest valve and the inboard sea chest valve). The advantage which a hydraulic valve provides is remote operation i.e. incase there was an ongoing flooding, then you don't have to go to the bottom platform (where it will be flooding and hence, unsafe for the operator of the valve) to shut the valve manually since the hydraulic pipes/actuation mechanism can be provided and the valve can be remotely operated from a higher deck (which is not yet flooded, example the Engine control room deck). I have not found any write up about this in any of the International publications. My answer to your question is solely based on what I think. It would be nice to hear if you find this explanation practical? Let me know and do SUBSCRIBE to my youtube channel 👍
Interesting video, would totally watch more videos about the ship you work on. Not sure why they’d be at varying heights, is it related to being loaded vs unloaded?
Regarding the different heights of the sea chest, it's because when we are in port the under keel clearance (distance between the ship's bottom and the ground is quite less, so, using a lower sea chest means we are introducing water from a deeper point...this could mean more dirt/sediments/sand etc when we are in port, so, then we switch to the high sea chest (which is taking in the water from a higher point and hence, it will be relatively free of the dirt and sediments)
@@RoamerRealm Brilliant and informative video, well-worth a like and subscription. I've looked through the comments and unless I'm mistaken, you have so far only been asked about and provided an answer to the question of varying heights for the sea chests. Could you also explain why we need one portside and one starboard side? Also, based on your answer above, does it follow that the high sea chest will be portside, while the low sea chest will be starboard side? Finally, apart from their spatial positioning in the hull, do the high and low sea chests otherwise vary in their size, capacity or function? Many thanks and please keep it up !
we can't have sea chest of same height on both sides as during high seas we use low sea chest as lower number things need to be filtered at high seas , whereas when we are in port we use high sea chest due to the increasing number of particles to be filtered as the ocean depth decreases.
Well said Koustav 👍 preventing excessive accidental intake of sediments due to less under keel clearance is one of the correct reasons for switching over the sea chest
Hi Koustav, please go through the comment section, some of the other guys have also mentioned some other reasons and we have had a small discussion about the same. If you have any doubts about anything, please ask and I will try to explain further. Do subscribe to my RUclips channel 👍
Hi Hari! I have covered this part in the video. You have to open the water connection valve and then purge the air out from the sea chest compartment via the vent valve. Once all air is gone and water comes out from the vent valve, close it and check for leaks around the sea chest. Let me know if you have any other questions and do subscribe to my RUclips channel 👍
Thanks a lot for your feedback! Regarding disposal, throwing it back into the sea defeats the purpose of "bio fouling", so, we used to pack it up in garbage bags and land it ashore along with garbage and oily rags while declaring it as "bio waste'. Let me know if you have any other questions and please do subscribe to my RUclips channel 👍
@@RoamerRealmThanks. Sure thing I'll subscribe. By the way I'm also a Marine Engineering graduate and currently applying. I believe some of the seafaring things are meant to be learned onboard, my bad if I didn't how to dispose them 😅 ✌️
Thanks for your support! Also, since you are starting out I would like to tell you to never hesitate to ask a question if you are in doubt. What you asked is a very valid question and you will be surprised to know that many experienced guys also just throw it back in the sea saying "it's just marine stuff" without realising the consequences of the action. So, don't worry about your question, it's nothing bad 👍
Hi Paul! Thanks for reaching out. To join merchant navy, the rules are decided by the Shipping Ministry/Arm of the Government which heads the shipping department. Being an American, you will be governed by American laws and unfortunately, I am not aware about those as I am from India. However, I am very sure that you will have to do "STCW" courses and "pre-sea training" before you join ship (because these are bare minimum mandatory courses). Further, the exact list of courses depend on the rank/department you want to pursue. Sorry, I don't think I can help you with much accurate information in this case. Do subscribe to my RUclips channel 👍 (if you are into this kind of content)
@@RoamerRealm well thank you friend for your detailed and thoughtful response. I must say your English (and your unspoken demeanor) is so good/natural that I would of thought you were born here in the States. I will do my own research and see what I find regarding entry level jobs. I know I have one Friend who started out on a river barge and his first duty assignment for a year was to paint the ship. By the time he finished the back of the vessel it was time to paint the front! Eventually he took tests administered by the US Coast Guard which permitted him to take on more responsibility and migrate his daily work environment into the pilot house where as before he just did labor roles. I subscribed to your channel. I have one more question: have you any stories to share about encountering pirates?
Thanks a lot for telling me about your friend. I understand what he did, but overall, it's exactly what you have mentioned - an entry level job, in other words, lots and lots of man-hours of labour for not the kind of money which classifies merchant navy as "lucrative". Agree, it may seem tempting that one can join ship immediately without having to wait a few months or a couple if years while trying to complete the diploma/degree or certain additional certification, but trust me, after being at sea for over 15 yrs, I can confirm that you should aim to join cargo/merchant ships as an officer/engineer only and do the school time it needs you to. There is a BIG difference between the quality of life, nature of work, salary structure, rank/career progression for officers Vs life of crew. If you are planning to be at sea for long term, try joining as an officer/engineer. Good luck.
Almost forgot, about the pirates, yes, we came across them on 2 occassions while transiting the Gulf of Aden back in the year 2013-2014. It was considered a high risk piracy area back then. Luckily, we spotted the pirate skiffs early enough and could take evasive manoeuvres to avoid them altogether.
Looks like the sea chest was full of microplastics. Please tell me this is not thrown back at sea? Also; if a ship has a blown head gasket or cracked head, is their a possibility that oil will leak out since ocean water is used for coolant? Great video!
Hi Dave! Thanks for your comment and for appreciating the the video. About your question, no, the micro plastics and everything else which is cleaned from the sea chest is stored separately and landed to shore garbage reception facility (when the ship is in port) as per the local/international laws applicable. For the 2nd question, please specify if you are talking about main engine cylinder head gasket? Or something else?
Most Ship engines are actually cooled by fresh water. The fresh water (flowing through the machinery) in turn is cooled by the sea water (flowing in a small system loop). Sea water is corrosive and leave sediments/salt behind, so, fresh water is used. Please let me know if I understood your question correctly…
Hi Graham! No, I don't think so. The MGPS system fitted does prolong the life of the sea water system components but the sea chest strainer filters out the physical impurities and hence, it will definitely get clogged over time. Also, as ship staff, we have zero control over the quality (or contamination levels) of sea water which we draw into the ship. Certain river passages with shallow depth (and hence, low under keel clearance under the ship) will lead to an even accelerated clogging Vs open/deep sea navigation with almost no mud/silt. Do let me know if my explanation answers your question, and please do ask away if you have any other follow up question. Thanks and do Subscribe to my RUclips channel 👍
Good video. Can I ask is the suction on these sea chest where the actual metal grates are in the hull of the ship actually strong? Could you be sucked against it?
Hi Richard! Thanks for your feedback, glad to know that you found the video helpful. About your question, it's very interesting. I have seen the grates in the hull during dry dock and while they do appear to be reasonably strong. Due to the curvature of ship's hull and water flow, I think the chances of getting sucked into the suction side of the propeller is far greater than being sucked onto the grating of the sea chest suction inlet.

@@RoamerRealm thank you for taking time out of your day to reply, have you done a video on the ventilation systems and heating and cooling for the living areas. Are ships using 100%outside air due to covid?
Very welcome, thanks for appreciating, I try my best to respond as quickly as I can... I haven't done a video about the ventilation system yet, thanks for the great idea. Despite covid, we are using the ventilation system as usual i.e. 100% fresh air from outside, cooled via freon in our refrigeration system and then supplied in living spaces and then 100% air out without any recirculation. I will try to do a video on the ventilation system soon. Thanks and have a nice day 👍
@richardc1983- Not sure if you will see my reply after so much time has passed, but coincidentally I arrived at this very educational channel because of a news article that I read. It was in regards to a DEA drug bust where a cartel had smuggled cocaine by putting it in the sea chest of a commercial ship. It went on to say that the reason the DEA was originally investigating, was because the diver who worked for the cartel to recover the load, actually drowned while attempting to recover it. They said that he was sucked against the inlet and ran out of air! I thought this was interesting and would help answer your original question.
Sure Ahmed, I will make a video about that in the coming days. When I go on ship the next time, I will start working on it. Thanks for your suggestion. Please do subscribe to my RUclips channel.
At the end, with the guy using his bare hands to strip the coating off the anode...made me cringe! BAD PPE policy! Let him grab a jelly tentacle, or get barnacles into his skin, and if he lives through it, he won't do it again! (Yes, barnacles CAN get on your skin, just like aquatic life, and burrow in to grow...it is rare, but it CAN happen! They head for your nerves (such as your carpel tunnel nerve, wrap around it, can cause EXQUISITE pain as they set up a colony...which requires multiple surgeries, and disfigurement of your hands, to remove)!
Don't confuse 'barnacle infestation' with 'skin barnacles'...where the latter is a type of ecsema...a 'barnacle infestation' is real life BARNACLES! Often happens to people who do hull stripping and prepping (for anti-fouling)...all it takes is a microscopic cut in your skin, so they can enter...definitely a possibility for ship maintenance crews!
I have to admit, I had no idea about these, so thanks a lot for bringing it up. I will do a read up about this as well to know about this a little better. Thanks a lot 👍
Oh! No, that's not what I meant. Being 2 years on that ship meant "back 2 back" for 2 years i.e. and the other 2nd Engineer, 3 months ON and 3 months OFF for 2 years

Andre, Merci beaucoup pour votre merveilleux commentaire avec de si beaux mots d'encouragement! Je suis heureux de savoir que vous avez trouvé la vidéo utile.
J'ai de l'expérience sur des navires travaillant avec différentes nationalités, certains qui parlent très bien anglais, d'autres qui ont besoin de peu d'aide. Il est important que tout le monde se comprenne au travail pour éviter tout accident. De même, je passe souvent quelques heures supplémentaires à ajouter des sous-titres à mes vidéos afin que même si quelqu'un n'a pas confiance en l'anglais, il puisse toujours regarder et comprendre à partir des sous-titres s'il le souhaite. Votre commentaire m'a fait très plaisir car je suis content que mon effort supplémentaire pour mettre des sous-titres montre un résultat :) Je ne parle pas le français, je tape ceci sur google translate. Merci pour vos voeux et bonne journée ! 👍
Thanks a lot for your wonderful comment with such nice words of encouragement! I am happy to know that you found the video helpful.
I have experience from ship working with different nationalities, some who speak very good English, some who need little help. It is important that everyone understand each other at work to avoid any accidents. Likewise, I am often spending few extra hours to add subtitles to my videos so that even if someone doesn't feel confident about English, they can still watch and understand from subtitles if they want to. Your comment made me very happy because I am glad my extra effort to put subtitles show some result :) I don't know French, I am typing this on google translate. Thanks for your wishes and have a nice day! 👍
you know, I use Google translate too.
my challenge is to write in english, and to watch if I use the rights words or not. More words comes to my practice.
Step by step, my understanding progress.
And I'm able to have a conversation with you today.
To be noted, the french text you wrote is perfect !
Have a nice day.
Thank you so much, I am very glad to chat with you too. Have a great day 👍
Actually vessels normally have a high sea chest, which is used to in shallow water to reduce intake of sediment, and low sea chest could be used when navigating in ice- covered water(when the ship is rolling to avoid losing suction..
Very well said! These are absolutely correct reasons 👍👍👍

Way back on Monte Cervantes😁
Very nice to hear from you :)
When ship is at anchored at port, the depth of sea bottom is low that is why we use High sea cheast. Because low sea cheast will suck mud.
When sailing, when the sea surface is deep, we use low sea chest suction.
Neo, well said. The under keel clearance is definitely one of the reasons. I hope you found the video informative. Do subscribe to my RUclips channel 👍
Sir, thank you very much for the time you took to do this video for us. It was very entertaining and educational for us landlubbers!
I wanted to ask you if you have ever heard of a vessel sinking because one of the sea chest gaskets (seals) or intake grates leaked? Also what brought me to your video was an episode of Australia 60-minutes. It was about how the drug cartels are actually smuggling their narcotics by putting them in the sea chests and the Australian police and customs officials are now using robotic video equipment to detect this. Very interesting indeed?
Hi Thomas! Thanks for your comment, I'm glad you enjoyed watching the video as much as I enjoyed making it. Coming to your question: Yes, flooding (and even sinking) is one of the main dangers while carrying out the sea chest cleaning. There have been ships in the past which have totally sunk due to the gasket seal or the valve seat failure. One if the points mentioned in the "Job Checklist" is that the area where cleaning is ongoing should never be left unattended (example - people worked on this for a few hrs and then went for a coffee or lunch break). Personally when I was getting this job done with my team, I would also start and then finish the job and give the team an early break or even a longer break at the end and everyone was happy. Regarding drug smuggling, well, the cartels are very very creative aren't they? I don't have any first hand experience but yes, they do try to smuggle stuff in the sea chest, underground part of the hull, bow thruster tunnel and what not...

A dumb question:: what is the need of pulling Sea water inside the ship, is it only for cooling purpose or there is more use?
Thanks a lot Praveen! Means a lot, your feedback and the nice words of appreciation! Really, thanks a lot! :) To answer your question: previously (30 years ago) most of the ship systems were Sea Water cooled, but due to sea water (salt) the piping, machinary etc will corrode faster and also will clog up faster during normal operation. Thus, at some point, the cooling system was changed to Fresh water cooled i.e. Sea Water comes in, cools the fresh water (already available onboard) and then the Sea water goes overboard while the Fresh Water s circulated and cools all the other systems. But overall, Sea water is just for cooling the Fresh water. Hope this answers :) Thanks a lot for your support with the channel!

Very welcome! I am glad this was helpful and thanks for checking it out and please do Subscribe to my channel!
Excelent video. Congratulations. I work in customs and border patrol in my country. Unfortunatley, we are having to much problems with drugs placed in the sea chest. The drugs usually are placed inside the sea chest and tied on the external grid. Criminal divers do this. I am not a mechanic engineer, but i am an eletric engineer. I have to ask you something: Is there any way we can insert a small camera on the sea chest, by inside the ship?
Is there any inspection window on the sea chest for the mecanics make a boroscopy? Another question: if the bags with drugs are placed in the sea chest, next to grid, can we look on the machines eletronic control and detect a water pressure (or flow) change? Thanks
Hi Diego, thanks for the nice comment and your words of appreciation. If you want then do Subscribe to my Channel, it helps. Coming to your questions:
About camera on sea chest - The sea chest is always pressurized with sea water from the overboard side. Inserting a camera would mean to find an opening on the sea chest from inside the Engine room to insert the camera. There are openings available, but personally I think no Chief Engineer or Master would allow it as it means a lot of extra job for the Crew (Isolating the sea chest, draining some of all of the sea water content to de-pressurize the sea chest, removing the mountings/flanges on top of the sea chest to facilitate the camera insertion etc...AND these mountings are not so big, so, the camera will also need to be really small (smaller than GoPro)...so, overall, I am not sure how feasible this is. Additionally, you might just be able to insert the camera but you have no control over the movement of the camera, so, you can really see everything. Moreover, the grill area which you're talking about where the drugs are usually installed, are still more to the outside of the sea chest and a camera inside sea chest still won't give access to the grill sections (because the isolative valves are just before and after the sea chest while the grill etc is closer to the sea side (before the overboard isolating valve) and that area cannot be isolated (unless divers are employed and they blank the sea side using plates). Hope this answers the first questions.
Next question about the flow change detection: There are pressure sensors installed on the sea water side (we need to know these values as well to monitor the running parameters, to monitor cooling efficiency or to detect ice when water temperature is really low during winter). The sensitivity of the instruments installed is not that amazing to detect a flow change due to some (or more) amount of drugs. I think if the entire sea chest area was filled with drugs, and the Sea water pumps were starved of sea water, so much so that there is really a drop in pressure, only then will it really show a pressure difference. Otherwise, I think these instruments will not be able to give you any signification data which can be used to detect drugs on the sea chest. Another thing - the pressure shown on the pressure gauge or on the remote monitoring system is the instantaneous Sea Water Pressure in the moment. The value also depends on how is the ship loaded with cargo (more cargo = more sinkage = more draught = ship is deeper into water = more pressure available (since pressure increases with depth). So, this would further make it complex for you to really determine if the pressure difference is due to drugs or due to cargo loading or due to ballast (different topic but ships can also take in sea water in dedicated tanks to increase/decrease their draught as required for stability reasons depending on cargo load distribution and navigational requirements. Hope this answers the second questions.
Let me know if you have any other questions and I'll be happy to help you. Have a nice day!
@@RoamerRealm Thank you for all your wonderful explanation. The idea of trying to insert the camera inside the ship came about because here, in the port, the water is very dark. Almost impossible to see the ship's hullI using a ROV (Remote Operated Vehicle). We already tried the ROV. About the pumps, i thought that the drug packages could cause a drop in the pump pressure. But, as you said, it would have to be a large amount of drugs. Another ideia came these days, about the sea chest cathodic protection system. I thought about whether the use of plastic to package drugs could disrupt the conductivity of the sea chest cathodic protection system (plastic is insulating) . Maybe the plastic use can make the controler of cathodic protection system use more current. Do you think you would have the sensitivity to detect it? Thanks
@diegoperes2287
You are welcome, happy to help you. Below are my thoughts about your latest comment:
If the water in the port is extremely dark, maybe a long term solution could be to use a dredger to clear out the sediments/underground marine growth in the port. If there is not enough UKC (under keel clearance) then these boats while arriving in the port stir up a lot of dirt/sediments and underwater visibility is further hindered. If allowed some time, these disturbed sediments settle again and maybe the visibility is better after sometime Vs when the ship has just arrived and Tugs are working along with Bow/Stern thrusters. So, if possible, you can plan the inspection of the ships accordingly or employ a dredger and deepen/widen/clean up the bottom bed of the port.
About the ICCP (Impressed current cathodic protection), this is a dynamic system and measures the instantaneous potential difference between the hull and the reference anodes. Ships hull surface area is huge compared to the small area on which the plastic/drugs are going to be stuck. The instrument might catch it but due to the small area, it will auto apply the corrective current to the system to compensate for the change in potential thinking that maybe some paint has peeled off or there is higher marine growth or maybe even a slight change in the density of water. This system can give usable indicators only when ship had a grounding or touched bottom and a large part of paint got peeled off or when ship went from sea water to fresh water (density change)….other than that this won’t give any meaningful difference in measured values as the system will automatically correct and supply the right current to the hull. Hope this answers the question. Let me know…

what to do if sea chest valves are not holding , and you have to clean Stanier .
Hi Ashish! Tricky situation…hard to give a straight forward answer. How bad is the leak? There is a drain valve on the sea chest which drains to the bilge well. If the rate of leak is very very low and you can keep the drain valve open and see that the pressure on the chest drops, then you can give it a shot by keeping the drain valve open while it drains to the bilge well while you try to clean the strainer BUT this is very very risky. I think the best way would be to bring this up with Chief Engineer and vessel superintendent and carry out a risk assessment. Maybe it could be possible to block the sea chest outlet using magnet/divers from the outside OR if the vessel is soon due for dry dock then it can be fixed properly during that time.

First of all I want to say your video was amazing and super helpful. I just finished my first year of school for marine engineering and I am working on a ferry boat as a cadet, but yeah I want to say the video was great and being able to see how your systems are the same but different at the same time was very helpful. Also the fact that you answer all the comments and questions is awesome and very informative. I just have one question the guys on my boat call the tank right after the sea chest a sea bay and I’m pretty sure it does the same thing as the mgps but I wanted to make sure so can you let me know if that’s a different thing or just a different name.
Hi Deni! Thanks a lot for your comment and thr nice words about the video, I am glad you find it informative nad helpful 👍 Coming to your question, sorry, but I am not familiar with that word "sea bay" with reference to the sea water system. It could also be something ship type specific, and since yours is a ferry and mine a container, maybe that's why I don't know that term. Nonetheless, if you could send me a pic (as an Instagram DM) of the piping system, I will have a look and try to figure out what is the function of the sea bay.

Very well explained. Thank you
Thanks a lot Minakshi for the nice feedback! Do subscribe to my RUclips channel if you are into travel and ship related videos 👍
@@RoamerRealm yea sure, will subscribe. Yes I do watch ship related videos. But i am mostly into deck videos as self is chief officer. Today was looking into ballast water pump filter cleaning related videos and found urs. Watched it and liked the same because of simplicity in explaining.
Thanks a lot, I take that ("simplicity in explaining") as a big compliment 👍
Hmm, about the ballast pump filter, just to be sure, you are looking for the line filter OR the filter on the ballast water treatment system? Let me know, I can try to help you out if that's ok with you..have a safe sail 👍
@@RoamerRealm Actually looking for both. But majorly line filter. I wanted to know what is the correct procedure for going ahead with line filter job if there is any.
Ok, I understand, here is for the line filter: you need to isolate and de-pressurize before opening, so, look for the valves before the filter (on the suction side) and after the pump (on the discharge side) (Usual arrangement is - piping-> filter->pump) to isolate the filter. The valves are usually butterfly type, make sure they are tightly shut. Open the vent on the filter and de-pressurize the isolated line. If the water is not stopping, it means that the valve is not holding. So, only proceed with opening the lid of the filter once sure that no more water is coming out. After this will be the usual filter cleaning and then assembly in reverse sequence. Once all assembled, open Sea to Sea, check for leaks, and close the filter vent when all air is purged out and only water is coming from there. That's it I think, system can be put back to normal after that. Let me know if you have any other questions 👍
Interesting and educative video
Thanks! I am glad this was helpful and thanks for checking it out. Please do Subscribe to my RUclips channel!
First, great video. So, about block valves on Sea Chest. I usually see a manual butterfly valve and an hydraulic butterfly valve (with handwheel). Why the hydraulic valve is used, insted of another manual one?
Thanks a lot Bernardo for your nice feedback! Coming to your question, I have actually sailed on ships which didn't have a hydraulic valve at all - yes, that's right, there were just 2 pieces manual valves i.e. before and after the sea chest (also known as the overboard sea chest valve and the inboard sea chest valve). The advantage which a hydraulic valve provides is remote operation i.e. incase there was an ongoing flooding, then you don't have to go to the bottom platform (where it will be flooding and hence, unsafe for the operator of the valve) to shut the valve manually since the hydraulic pipes/actuation mechanism can be provided and the valve can be remotely operated from a higher deck (which is not yet flooded, example the Engine control room deck). I have not found any write up about this in any of the International publications. My answer to your question is solely based on what I think. It would be nice to hear if you find this explanation practical? Let me know and do SUBSCRIBE to my youtube channel 👍
Interesting video, would totally watch more videos about the ship you work on.
Not sure why they’d be at varying heights, is it related to being loaded vs unloaded?
Thanks a lot for your kind words! :) I will try to post more ship related videos as well from time to time 👍
Regarding the different heights of the sea chest, it's because when we are in port the under keel clearance (distance between the ship's bottom and the ground is quite less, so, using a lower sea chest means we are introducing water from a deeper point...this could mean more dirt/sediments/sand etc when we are in port, so, then we switch to the high sea chest (which is taking in the water from a higher point and hence, it will be relatively free of the dirt and sediments)
Oh awesome, makes complete sense. This video reminds me of the recent submarine video on smarter every day, super cool.
Thank you so much 👍
@@RoamerRealm Brilliant and informative video, well-worth a like and subscription. I've looked through the comments and unless I'm mistaken, you have so far only been asked about and provided an answer to the question of varying heights for the sea chests. Could you also explain why we need one portside and one starboard side? Also, based on your answer above, does it follow that the high sea chest will be portside, while the low sea chest will be starboard side? Finally, apart from their spatial positioning in the hull, do the high and low sea chests otherwise vary in their size, capacity or function? Many thanks and please keep it up !
we can't have sea chest of same height on both sides as during high seas we use low sea chest as lower number things need to be filtered at high seas , whereas when we are in port we use high sea chest due to the increasing number of particles to be filtered as the ocean depth decreases.
Well said Koustav 👍 preventing excessive accidental intake of sediments due to less under keel clearance is one of the correct reasons for switching over the sea chest
@@RoamerRealm Sir as you said it is ONE OF THE CORRECT REASONS , sir what would be the other reasons ?
It would help me help me out a lot .

Sir after replacing the seachest how to check the leakage
Hi Hari! I have covered this part in the video. You have to open the water connection valve and then purge the air out from the sea chest compartment via the vent valve. Once all air is gone and water comes out from the vent valve, close it and check for leaks around the sea chest. Let me know if you have any other questions and do subscribe to my RUclips channel 👍

Also, since you are starting out I would like to tell you to never hesitate to ask a question if you are in doubt.

So, don't worry about your question, it's nothing bad 👍
Can you give any advice on how I as an American can get an entry level job on a merchant ship? Must I go to school first?
Hi Paul! Thanks for reaching out. To join merchant navy, the rules are decided by the Shipping Ministry/Arm of the Government which heads the shipping department. Being an American, you will be governed by American laws and unfortunately, I am not aware about those as I am from India. However, I am very sure that you will have to do "STCW" courses and "pre-sea training" before you join ship (because these are bare minimum mandatory courses). Further, the exact list of courses depend on the rank/department you want to pursue. Sorry, I don't think I can help you with much accurate information in this case. Do subscribe to my RUclips channel 👍 (if you are into this kind of content)
@@RoamerRealm well thank you friend for your detailed and thoughtful response. I must say your English (and your unspoken demeanor) is so good/natural that I would of thought you were born here in the States.
I will do my own research and see what I find regarding entry level jobs. I know I have one Friend who started out on a river barge and his first duty assignment for a year was to paint the ship. By the time he finished the back of the vessel it was time to paint the front! Eventually he took tests administered by the US Coast Guard which permitted him to take on more responsibility and migrate his daily work environment into the pilot house where as before he just did labor roles.
I subscribed to your channel. I have one more question: have you any stories to share about encountering pirates?
Thanks a lot for telling me about your friend. I understand what he did, but overall, it's exactly what you have mentioned - an entry level job, in other words, lots and lots of man-hours of labour for not the kind of money which classifies merchant navy as "lucrative". Agree, it may seem tempting that one can join ship immediately without having to wait a few months or a couple if years while trying to complete the diploma/degree or certain additional certification, but trust me, after being at sea for over 15 yrs, I can confirm that you should aim to join cargo/merchant ships as an officer/engineer only and do the school time it needs you to. There is a BIG difference between the quality of life, nature of work, salary structure, rank/career progression for officers Vs life of crew. If you are planning to be at sea for long term, try joining as an officer/engineer. Good luck.
Almost forgot, about the pirates, yes, we came across them on 2 occassions while transiting the Gulf of Aden back in the year 2013-2014. It was considered a high risk piracy area back then. Luckily, we spotted the pirate skiffs early enough and could take evasive manoeuvres to avoid them altogether.

Looks like the sea chest was full of microplastics. Please tell me this is not thrown back at sea? Also; if a ship has a blown head gasket or cracked head, is their a possibility that oil will leak out since ocean water is used for coolant? Great video!
Hi Dave! Thanks for your comment and for appreciating the the video. About your question, no, the micro plastics and everything else which is cleaned from the sea chest is stored separately and landed to shore garbage reception facility (when the ship is in port) as per the local/international laws applicable.
For the 2nd question, please specify if you are talking about main engine cylinder head gasket? Or something else?
@@RoamerRealm Thanks for the response! How are ship engines cooled? I assumed seawater?
Most Ship engines are actually cooled by fresh water. The fresh water (flowing through the machinery) in turn is cooled by the sea water (flowing in a small system loop). Sea water is corrosive and leave sediments/salt behind, so, fresh water is used. Please let me know if I understood your question correctly…
Any products that could treat the seawater to extend the amount of times you have to clean these?
Hi Graham! No, I don't think so. The MGPS system fitted does prolong the life of the sea water system components but the sea chest strainer filters out the physical impurities and hence, it will definitely get clogged over time. Also, as ship staff, we have zero control over the quality (or contamination levels) of sea water which we draw into the ship. Certain river passages with shallow depth (and hence, low under keel clearance under the ship) will lead to an even accelerated clogging Vs open/deep sea navigation with almost no mud/silt.

Good video. Can I ask is the suction on these sea chest where the actual metal grates are in the hull of the ship actually strong? Could you be sucked against it?
Hi Richard! Thanks for your feedback, glad to know that you found the video helpful. About your question, it's very interesting. I have seen the grates in the hull during dry dock and while they do appear to be reasonably strong. Due to the curvature of ship's hull and water flow, I think the chances of getting sucked into the suction side of the propeller is far greater than being sucked onto the grating of the sea chest suction inlet.

@@RoamerRealm thank you for taking time out of your day to reply, have you done a video on the ventilation systems and heating and cooling for the living areas. Are ships using 100%outside air due to covid?
Very welcome, thanks for appreciating, I try my best to respond as quickly as I can...
I haven't done a video about the ventilation system yet, thanks for the great idea. Despite covid, we are using the ventilation system as usual i.e. 100% fresh air from outside, cooled via freon in our refrigeration system and then supplied in living spaces and then 100% air out without any recirculation. I will try to do a video on the ventilation system soon. Thanks and have a nice day 👍
@richardc1983- Not sure if you will see my reply after so much time has passed, but coincidentally I arrived at this very educational channel because of a news article that I read. It was in regards to a DEA drug bust where a cartel had smuggled cocaine by putting it in the sea chest of a commercial ship. It went on to say that the reason the DEA was originally investigating, was because the diver who worked for the cartel to recover the load, actually drowned while attempting to recover it. They said that he was sucked against the inlet and ran out of air! I thought this was interesting and would help answer your original question.

At the end, with the guy using his bare hands to strip the coating off the anode...made me cringe! BAD PPE policy! Let him grab a jelly tentacle, or get barnacles into his skin, and if he lives through it, he won't do it again! (Yes, barnacles CAN get on your skin, just like aquatic life, and burrow in to grow...it is rare, but it CAN happen! They head for your nerves (such as your carpel tunnel nerve, wrap around it, can cause EXQUISITE pain as they set up a colony...which requires multiple surgeries, and disfigurement of your hands, to remove)!
Don't confuse 'barnacle infestation' with 'skin barnacles'...where the latter is a type of ecsema...a 'barnacle infestation' is real life BARNACLES! Often happens to people who do hull stripping and prepping (for anti-fouling)...all it takes is a microscopic cut in your skin, so they can enter...definitely a possibility for ship maintenance crews!

Did you really sail continuously for 2 years on this ship ?
Oh! No, that's not what I meant. Being 2 years on that ship meant "back 2 back" for 2 years i.e. and the other 2nd Engineer, 3 months ON and 3 months OFF for 2 years
