Excellent, Ramesh. Again you done justice to the tricky subject. Very clearly explained. Expect many more like this. Bravo👌🌹

[@rmetcvideos]

Thanks a lot sir..a thumbs up from you means a lot🙏🙏

[@babaktaheri7836]

After 12 years of sailing now i understand totall hyrolic lock alarm and logic behind it. Thank you Sir🙏

[@sumitchoudhary4426]

Excellent job done by you sir

[@deepakshanmughan7928]

Thank you sir for explaining the concepts... Was never able to understand the concept because of the words written in such rules and no good explanations were available which i was able to understand . Video helped to understand the concept...

Thank u sir , for all valuable information.

excellent one....first of all a big sorry for watching late...actually was not well whole family was suffering from severe viral...now we have partly recovered...now coming back to video...very useful...very informative ...words are less to appreciate your efforts in simplifying such a complex theory in a simple way...hats off sir....and i am proud to say that..very few in our industry are knowledgeable like you...really well done sir...stay safe ...god bless you...awaiting new video on steering circuit...if possible cover in detail four ram...with all fail safe and change over..thanks alot

[@rmetcvideos]

:-).Thats being very generous. My knowledge limited to limited topics. wonder if I can pass Class 4 as of Today :-)

[@anand5762]

Thanks for explaining very clearly sir.

[@harishkumardevadas4727]

Good Eve sir Kindly make video on Purging air from Steering system and cause and effect of air in the system

[@1991shalabhagarwal]

This gives a clear picture of what is happening inside the hydraulic system. Just had one doubt about the relief valves, that when SOLAS says that the relief valve is supposed to be set at 1.25 times of the working pressure, why do we have Class saying that it should be set at 1.1%?

[@rmetcvideos]

I guess the 1.1 % is for Capacity not pressure. For opressure it is 1.25 but the INCREASE in pressure shud not be more tha 1.1 %

[@shankarrams3834]

Good effort. .If two systems are running and a hydraulic alarm is raised, by swiching off one system and operating with only one system should solve the problem. Is this correct????

[@abdussattarakhanda8696]

thank u sir .....sir please make more video regarding regulation...specially SEEMP,EEDI,EEOI

[@rmetcvideos]

Dont you think they are dry topics. Still I will try...Thanks

@@rmetcvideos sir but it is important to understand clearly as it is too much confusing ..

Hello sir thanks a lot for sharing such valuable information... Helping a lot in clearing class 2 exams One request please can you please share knowledge on how to read electrical /electrical diagramas

[@rmetcvideos]

Probably asking the wrong guy...😂. I might Not make a video on this topic ---since I wish you pass the exams --😂😂

[@bjmarine8]

SIR , can u make clear the point at 7:58 of video ...if you have 2 main s/g ,two control system also to be there, and to be independent exception can made if you have telemotor system - in this point the control system means is that emergency steering which we are doing manually or whats meant by control system

[@sankalpsingh1474]

Sir if time permits please upload videos once a week atleast , there is a lot to learn , thanks a lot sir , solas language doesn't look so lethal now .🙏

[@rmetcvideos]

:-) I will try my best

[@sureshrajendran1119]

Good day sir, Short circuit protections are provided for both control and main power circuit. Does it mean that it only provides alarm ? Or does it mean there is a trip protection against short circuit ?

[@rmetcvideos]

Short circuit..Trip...and alarm always...only overload trip for power circ is optional with a setting of 200 %

[@taljeetsingh1226]

what are the action we should take in case we get the alarm .

[@rmetcvideos]

which particular alarm???

[@mahedihasan6817]

Respected sir,expecting turbocharger o'hauling video, tks

[@rmetcvideos]

I dont work on ship..so I might not have the resources...But I guess there must be many good ones on You tube

[@shekharpataku]

Sir please explai pintle bearing clearance method

[@rmetcvideos]

OK..will try.

[@RITESHKUMAR-te3pp]

Sir...you said that when the rotory vane steering gear is on hydraulic lock by the isolating valves...the isolating relief valve is in command if sea forces hit the rudder then the rudder must have moved by some degrees...in that case sir...how can we take back the rudder to its default place..if it is in hydraulic locking condition..?

[@rmetcvideos]

You are right..The rudder does change position due to sea water waves hitting it due to The shock absorber valves . But this change in Rudder position results in a deviation from the set point. Hence a new corrective action generated. Isolating valves have no role to play in this scenario

[@RITESHKUMAR-te3pp]

@@rmetcvideos does that corrective action generated by gyro...?

[@rmetcvideos]

@@RITESHKUMAR-te3pp gyro gives the feed...auto pilot releases the signal...

Sir i request you to please make a video on PID on steering gear.

[@chaitalimhamunkar2449]

sir if surveyor ask us what is 100% redundancy and what is 50% please tell us what to answer for this

[@rmetcvideos]

Difficult question bcoz it depends on interpretation of surveyor also. However I will tell you my answer basis some guidance from class advise Giving steering gear as example...A steering gear needs to move rudder in 28 secs as per SOLAS . Depending on ship type as you have seen in video, it can be done with 2 pumps simultaneously. In this case -- 50 % redundancy. In case EACH of the pump was capable of moving the rudder in 28 secs... 100 % redundancy. I still advise you to tell the answer which the surveyor wants to hear..

[@chaitalimhamunkar2449]

@@rmetcvideos sir can we say in case of failure in one unit of system if it is able to achieve requirement o 28 sec it is 100%
