NAVEET YADAV:
Mep n Motor
-Electrochemical corrosion
-elongation of con rod bolt
-low n high carbon steel difference
- boiler gauge glass changing procedure
-bilge pump not taking suc from bilge well,reasons.
- difference b/w inside n outside calliper. How yo use inside calliper as outside calliper.
- spring gauge
- aux. Eng alarms n trips

-You are in accomodation suddenly galley fire is there what will you do, what type of fire
-only one generator is running and exhaust trunking is red hot, actions
-ae crankcase inspection
-oil in boiler cascade tank, actions

Int : Choudhary sir
Ext : SKD sir
1)type of vessel
2)bhp and kw
3)centrifugal pump wear ring and position
4)thrust block and function who produce thrust
5)what will u do in case if refer pipe got hole (brazing full procedure)
6)Generator not starting on air after decarb reasons
7)when to decide piston ring wear away and how u decide it
8)Steam trap ,water hammer types of hammer how u will prevent it and what all ways in detail
9)in between asked whether u worked on 2 stroke or 4 stroke ,i said 4s then asked about whether u had purifier i said yes then asked about overflow and what is ur action
10)boiler backfire and what is your action not satisfies with answer
Result : Ok Mr Akshai you got Motor❤️ repeat MEP (still answered 90% one two qustns he was not satisfied )
Fun 4B and 6
Ignition delay
Sensiblility of governor
Fwg evaporator vaccum maintain
Anchor chain calibration
Boiler burner safety
Bolier alarm
Aux engine liner decarb
Air bottle routine
Veg room temp not maintaining action
Tie rod and types
Got function 4B
Repeat function 6✌🏻
