I have a question. Any who knows the answer should kindly share please. Why is low expansion foam no longer allowed as the only fixed fire fighting system onboard ships?
Low expansion foam is used on deck for extinguishing the fire (mainly for open area fire) but co2 is used for closed area fire (such as engine room ,cargo hold,pump room etc) so normally you will find 2 extinguishing system onboard
Nice explanation sir. Thanks for the valuable information. Sir I have a question ..... Why earlier in Sulzer engine jack bolts for the main bearing are inclined?
Hello Pawan , Sulzer engine jack bolt for main bearing is inclined so that to ensure that the shaft bending stress is less at the centre as the hole can be cut more closer to the centreline of the crankshaft which provides better crankshaft alignment and less bending stress. If you want to more soon video regarding this topic will be uploaded u will get more clear idea. Till then please share my other video in your facebook and whatsapp status.
Tie rods should be as near as possile to the center line. since bending moment = force * distance. Jack bolt is an arrangment which holds the top cover of main bearing in position. By eliminating the requirement of bolts to hold it and reduces the width of top cover, so that tie rod can be bought close to the center line of engine.

Thank you, subscribed.

@@MarineEngineeringHub I do sir !!!
Everything is good, please just keep the mic away when u speak
sir how is the orifice meter changed from low to high expansion is it done manually by going to the proportionator? plz reply
thanks for the explanation...could u pls share throw length of a foam applicator and a foam monitor.
Sir,,,my question
'3'compounds are needed to make foam are water,foam AFFF Or air...
So you tell me from where to get air compound....
While coming out at the end !!!!
Air suck in to form mixture with foam liquid to come out as foam
Greatly explained
Glad it was helpful!!!!!
Thank you for your response!!!!!

Regulations are much oriented towards cargo tanks for oil and chemical tanker and not about cargo holds of car carrier ship.
thank you bos

Marine Engineering Hub okayy i already pass my 3rd class oral exam yesterday . thank you for some of ur video made me cleared of some topic :)
Too good
Thank you for your response.!!!! Please do share our video on your facebook and whatsapp group!!!!
High expansion is for deck and low expension is for engine room.
No opposite
As high expansion tends to get away with wind so the expansion ratio is kept less!!!!
No bro. The reverse is actually the case.
