@@aungphonenaing3358 no you are not wrong, 480 KN is SDMBL.

@@marinetecs4436 Thank for your information, sir

Thank you so much sir! Please Use formula P=10F/A(Mpa) to find out the jack up force (F) exerted for rendering. Than use above formula to find out the torque (T). Torque T is the rendering value of brake ( column J) Hope this will help. Thanks n regards

Sir, kindly watch the video carefully, you may find the answer there.

Request you to kindly tell us the position in video so that we could answer your question

That’s embarkation ladder used during emergency to climb down into life raft or lifeboat. It’s covered to protect the rope, d-shackle and steps from weather because ladder is made of Manila rope and combination of rubber and wooden steps which may get deteriorated due to exposure to weather and sea water.

thank ypu so much sir

I feel it depends upon the type of davits and boats. An open boat if boarded from stowed position is riskier as person may fall off when the davit swings out from it's stowed position where this is not the case with totally enclosed lifeboats. if the davit is arranged in such a way that for lowering the boat it doesn't need to be swing out (as in case of oil platforms) than the boat can be boarded from the stowed position. in that case it doesn't matter whether the boat is an open boat or an enclosed boat.

Sir, you are correct that if the brake liner is worn out it will affect the tightening and if you tight the Brake flowing the previous makings, chances are that Brake may slip off earlier. this is one aspect and other aspects which can affect the brake tightening are *Wear down or play in Brake linkages and tightening mechanism. * weardown of Brake drum etc

Thank you so much Mukul, the force of fittings can be referred in mooring fitting arrangement manual, which is available on most of the ships.

Thank you so much sir for the Appreciation

Dear Faey Appreciate you for responding the video, your suggestion may hold good in specific cases such as where the new type of hook system is used as in cases of “Viking Hook” also called as “Nadira Drop in Ball system”. In this new kind of system the falls having ball shaped ends are attached to the securing arrangement on boat at last. Due regards to your suggestions I would like to insists that while operating any safety equipment onboard always follow ship specific makers operating procedures. In my video, we have followed makers operations procedures where it doesn’t allow reseting of hooks before bringing the links in position. Hope it is correctly justified.

Thank you so much Sir for appreciation!

Thank you so much !

Hello sir great video, please share (if possible) complete overhaul of tanabe air compressor, (if it is on ur ship & due for overhaul) .

@@harshranjan7072 thank you so much sir, I have stuff to make a good video on Tanabe Air compressor O'Haul, presently I am working on a different video hence will try to make a video on air comp. after that.

@@marinetecs4436 thank you for considering my request sir, ur video on conrod bolt renewal had helped us a lot during AE decarb. Also sir I'm much junior to u (4E) pls don't call me sir. 🙏🙏

Thank you so much sir!

Thank you van for responding the video, For documents I need to check my archive where documents are present related to onboard incidence of explosion of medical oxygen bottle when tried to charge with the help of SCBA compressors. The reason of not charging medical oxygen bottle is simple, shipboard medical oxygen bottle contains liquified oxygen which is highly inflammable. When these bottles are tried to be charged directly with the help of SCBA compressors the hot air from SCBA compressor causes rapid increase of pressure inside the medical oxygen bottle this happens when some amount of liquid oxygen left over in the bottle. Rapidly increases in bottle causes explosion in medical oxygen bottle. I hope this should suffice. Please give me some time to share the concerned documents.

It's very gud video sir why water is put in bucket n wen air bottles filling is done ??can u please tell me sir?

Thank you Mr. Vaibhav for responding the video. IG is required for tankers above 20000DWT, There are two main reasons 1. During cargo discharge the atmosphere inside the tank to be kept below Lower explosive limit ( LEL). The level/amount of explosive gases in case of tankers is much higher than the fuel oil tanks. 2. During cargo discharge generation of static electricity is another problem which is required to be dealt with. Static electricity acts as the ignition source. In case of fuel oil tank generation of static electricity is not there. Hence there are the two main reasons because of which IG is not required for fuel oil tanks. I hope this should suffice.

Hello Arun, thanks for responding the video, In case of complete power failure to motor, there is always an arrangement for lifting the boat with the help of hand lever.

@@marinetecs4436 thanks

Using manually system

Thank you so much for showing your interest in the video, Would appreciate if you could send a request on our email support@marinetecs.com Best regards

Good question indeed Sahil, It is the significant wave height which governs the minimum speed requirement of life/rescue boat winch. In simple terms, minimum speed is required to lift the boat from water as quick as possible and by doing so waves effect on hoisting could be minimised. Thank you so much for posting your comments

@@marinetecs4436 got it..🙏 thnk u

Thank you so much Sandeep

I think the same 👍
