Sir i have great respect for you, as u know now a days nobody giving knowledge for free and u doing such good job and the way describing the topic is awesome...u always be in my pray sir....
So nice of you
This should have a million views. Thank you sir. I have been confused between these modes for years.
very clear message sir..thanks millions from Myanmar
Great Sir..I am an ETO..But i really appreciate the words you said last..
Glad to hear that
Very good presentation. All aspects of rudder hunting has been dealt with. Congratulations dear Ramesh for painstakingly made the animation. It will definetly be helpful to many Chief Engineers to understand the working principle and systematic fault finding. Thanks once again. On follow up mode, Rudder remains in the position as long as steering wheel is kept at that position. If the steering wheel is spring loaded, the moment you leave the wheel, rudder will come back to midship.
Excellent explanation Ramesh, for a novice and trouble shooting for sailing / shore support team.
Conclusion was also interesting, electrical officer to solve problems outside engine room😊
it is great value addition to humanity, people with experience and knowledge sharing it with public. Great purpose. Meaningfull life indeed. Thanks for the vid sir!!
Very helpful sir...Thank you...
Crystal clear sir keep doing sir🙏
Very much informative....thanks
Very informative
Best presentation. A lot of doubts on this one cleared. Thank you sir.. 🙏
you prolly dont give a shit but does any of you know of a trick to log back into an instagram account?
I was stupid lost my password. I would appreciate any assistance you can give me
@Jose Peter instablaster :)
@Aydin Owen I really appreciate your reply. I found the site through google and I'm trying it out now.
I see it takes a while so I will get back to you later when my account password hopefully is recovered.
@Aydin Owen it did the trick and I now got access to my account again. I'm so happy!
Thanks so much you really help me out :D
@Jose Peter you are welcome xD
very helpfull specially with the animations thanks bada saab
Awesome presentation thanks a lot sir
very good video sir.....looking forward for more videos on steering....if possible cover hydraulic parts with modern steerings .....and if autopilot and transmitter are within your scope then please try to cover also that....stay healthy sir....
Sure..Will try and keep it in my to do list.Time permits, I would love to...
good explanation and good topic , was trying to find for 1 hrs non follow up mode explained like this and could not find untill i come across your video
Would you please tell me when to use non follow up mode?
@@mohammadaktaruzzaman2826 when the follow up mode fails
Thanks a lot sir for your valuable videos. They helped to clear many doubts and render a better service. Wish you good health sir.
Very nice Explanation
Thanks sir. Very helpful for our exams.
May god bless you and your family.
Thank you so much sir. All your videos are very informative for basic learners and clear explanation.today I cleared class 4 orals with help of your videos,specially that rudder and propeller. drop videos helped me. Thank you sir
Keep it up.Wish to see you as Chief Engineer soon.
Excellent
Chief u r doing good for us i am talking 2 engr course ur video is really worthy for me
Sir I am from deck side but still this videos help us alot.. Thank you sir
thank u sir..keep going
Best presentation sir thank you sir ...
Thanks for making this lectures , all my respect 🙏
Very useful video sir.watching from Bangladesh ❣️
thank you very much the guys working with you are lucky. Please make more videos
Thank you for this video (regarding from Srilanka)
Lol, so true sir. Anything that has a wire associated is naturally an electrical officers problem 😊😬
Such a great channel .... Hats off to u sir🙌👏
Very helpful
Thanks chief.... these videos are a lot of help
Thank you sir..keep posting new topics
Thank you Sir! Great video very helpfull. Godbless you.
Thank you very much for this great video
Excellent explaing sir.thanks .
Very helpful video sir.thank you sir
One of my friend was telling me that during his watch as a third officer his captain who jut joined the ship one day back asked Bosun to put the ship to FOLLOW-UP mode from AUTO PILOT and he did so but she was still at AUTO PILOT and captain got panic that why steering is not coming on auto and called every officer on Bridge meanwhile third officer told him that it is because the NOBE or LEVER might came out and BOSUN while putting it back changed it to FOLLOW-UP while original position still at the auto pilot and after checking it was found that this is the problem.
Great information sir
Sir, thank you so much for uploading your wonderful videos. I love your animation, slides, and your excellent explanation!! Sir, if it would be all possible, in the future, would you please make a video on 24VDC battery charger insulation troubleshooting? One of our ships had a faulty AVR and thus the general use batteries could not be charged.
will try..would love to cover all topics. But making videos require a lot of time.
Like always more beautifully done sir, every time with a better presentation than before. Sir in troubleshooting hydraulic about the sticky solenoid valve point, is there a possibility of this jerky nature of rudder to be because of pitching of ship in rough weather ? Can that be taken into account before jumping into faulty solenoid valve or so conclusion?
Also, can air trapped in the hydraulic system due to leakage in the system be the reason for slow response of the rudder movement on either direction? I mean if rudder is responding slow movement only on one side i.e either port or starboard?
the checking of air in the system is the first step,eventhough it is very unlikely .if ram packings are bad there are chances.
ssr
Hi Tousiff..Tnks for you kind words as always.Air in the system is always a possibility, but the reasoning which I always hear is suspect in my opinion. I find it hard to believe that a leak will cause air ingress. Hydraulics is always about high to medium pressure oil always being available in every part of the line..So question of Air ingress should never Arise.So my belief is that in OPen loop Hydraulic system , where pump takes suction from TANK..Air can Enter due to two reasons--- Low level Of OIl in Tank which during Pitching can contribute to momentary air ingress. Other more likely point is..When you have low level of oil in Tank (Maybe still more than Alarm Level), The return Oil from deck etc ..if it FALLS from a height inside the tank ...can cause a lot of bubbling and this can find its way to pump suction.Even in a Ram type steering Gear ..and the RAm seals are Defective..OIL will LEAK for Sure.. but still Air will not enter the system through the seal. This is my reasoning. Have a Look at the the 4 ram circuit..Introspect ...See if you are able to understand my thought process...
@@rmetcvideos thank you sir, will definitely look into 4 ram.
excellent sir, many thanks..
Good explanation sir!
Superb class sir
Thank you so much for your support ❤️
Thank you so much Chief
Nice video , thanks
nice one
Excellent explanation sir , I have seen your other videos also very well explained 👍🏻👍🏻. I have one request from you can you please make a video on Main engine system lubrication ? 🙏🏻🙏🏻🙏🏻
sure,,will add to list
Thank you very much sir
Thank you sir
Thank u sir... Understood
Always welcome
Good presentation. I have one question. How much is hard port or stbd? In your video you have shown it as 30 deg. I have seen many a Master argue it should be 35 deg or till it reaches its limit. Your view on this please. TIA.
it is point of view..As per rules Rudder shud move till 35...But as per effectiveness 30 is almost as effective as 35..like a valve 99 % open and 100 % open..no bog difference
Thanks a lot
Thank you sir....can u pls make video on VIT and super VIT....little confusing
Ok sure
Sir, could you please make a video on thrust block and how to take its clearance
What's the software which is used here ?
Excellent presentation
graphic designing software from serif
Dear chief sorry to tell you that no ship can sail without electrical officer as they are the pivotal aspects of the control and automation system.. I have seen chief engineers without even having knowledge in racking out a VCB or changing a contactor. I met with a 3rd engineer who debated with me over a mechanical fault telling me it was a electrical fault...
Sir, it's a very good presentation. What's the position no. 4. WINGS.
Tnks .I havent sailed in such ships, but I guess it must be for controlling the steering from the Bridge wings if such a provision is available on some ships
@@rmetcvideos . Thank you for taking your valuable time to reply me sir.
@@dinesha3886 Yes Bada Saab it is for controlling the ships from bridge wings
sir plz make a video on p i d controller
Why in most of the ships ram type steering gears are used ?
Not necessray..We have many ships with Vane type
how steering gear get signal from bridge helm order to rudder angle final position... in electro-hydroulic steering gear
Comparision in Auto Pilot console.. signal to actuating mechanism -in sync with Feedback from Rudder ANgle transmitter
Ive always wanted to know, can a vessel move in a straight line, even though knowing that propellers is subjected to tranverse thrust, on upper and lower blade, and since the upper and lower blade operate on different depths, the transverse thrust can never be equalized, so ive read that this unbalanace causes angular thrust which pushes the vessel to go either port or stbd side ( depending on if its right or left handed propeller ) alittle, so could someone please confirm if this is true and false
Yes you are correct..
If steering gear hunting . Action you will take as a C/E?
Find out if problem is in bridge or hydraulic..use non follow up to find it out...detailed explanation in this video itself..go to about 19 minutes in this video and you can find the details
Sorry, how is NFU method is actually working? What is happening after we move the controller left or right? Plz sir i have so much confusion
The rudder will KEEP on going to port as long as the controller is operated..In FU mode you tell the rudder to go to a PARTICULAR angle, but in NFU mode u can only tel it yo go to prt side or Stbd side
@@rmetcvideos agreed sir but my question is where the signal is going? I read somewhere by NFU mode we are controlling 3 solenoid v/vs. Particularly I have confusion about the working.
In non follow up operate directional valve manualy untill rudder reach to desired angle. Onece you release the joistic directional valve come back to normal position and no oil feed to rams and hydraulic locking keep remain. That means rudder angle in desired angle. This is same like you carrying out emergency steering drill for electro hydraulic steering gear system from steering gear room. In non follow up system no feed back signal. As far as you are puting the joistic rudder will move. Once you release it keep rudder in that angle
Follow up ,non follow up or auto pilot signal goes to solonoids of directional valves in hydraulic system in steering gear room
@@bhageshkatoch2944 In NFU your solenoids are not working.But when you move your joystick to directions of port or stbd ,you operate the directional valve indirectly. Like for the duration you hold the joystick to port or stbd,for the same duration your directional valve of the chosen direction remains open and hydraulic oil goes to move the ram in that direction. Once you leave the joystick(i.e. joystick comes to its original state) your directional valve closes and there is hydraulic locking of rudder at that angle .The angle you yourself check at the angle indicator and leave joystick accordingly.
Actually,the feed back for the follow up mode of steering control is from a potentiometer which is located near the rudder stock and linked so that the turning movement of the stock is transferred to the potentiometer.This trans mitter has nothing to do with the rudder angle indication.For this purpose(indication) a synchro transmitter is used and fitted and linked same as the feed back potentiometer.Both transmitters have different function nothing in common.Narrative regarding NFU could have been better if described the need for using this mode and about control supply arrangement during this operation.Good effort but needs more improvement.
NFU things are not for engineers sir and we don't steer the ship. we just do the fault finding and rectify it and its the basic and from that we can understand that NFU's are for turning the ship instantaneously to hard port or hard starboard
Excellent sir excellent
Really l laughed about presuming the problem to be electrical... that's a funny truth. Call bathisaab
It was a great video sir and really informative , Learning all concepts easily keeps teaching sir🌹🫀
Thanks a lot sir for knowledge sharing.
really helpful
Thank you Sir
Thank you sir
