Chaki

Motor

1. Engine specifications

2. Advantages of super long stroke

3. Why refer compressor does not have crankcase relief door

4What will happen if late ignition happens

5. Why is boiler manhole door elliptical


Mep

1. ❌ Head clearance procedure

2. During AE Decarb, how to lock the liner

3. Safeties of steering gear

4. Purifier is vibrating, what are the reasons

5. Source of lube oil contamination


Ext Km Rao

1. Air in ac system ( accepted fluctuating high pressure in discharge side)

2.boiler gauge blowdown

3. Cutting of flange of sea water pipe

4.flaring tool and where it's used

5. Importance of Blacklash in gear


Ext - GOP

Int- chaki

1. One unit knocking all parameters ok, reason ?

2. Boiler routine maintenance

3. OWS working principle

4. Checks in centrifugal pump after overhaul

5. Air in steering system indication.

Result : repeat


MEP

External - Nag (may be)

tappet clearance measurement

Gauge glass blow down

Refer compressor short cycling

Bumping clearance.where to add shims

A/E not starting on air.Reasons

Result - COC


Internal chaki

External  hope

Mep

Ballast pump not discharging reason?

How to control excess pressure of steam?

How to identify inlet and exhaust valve kept in spare parts?

Compressor performance decreasing reason?


Mep

External- nag

Internal - akc

Function - MROL

Tappet clearance procedure 

Heat exchanger pr test

A/E not starting on starting air reasons 

Refrigeration system air removal procedure

Boiler start from cold

Purifier overflow reasons 

Result - pass

FUNCTION: 6

INT: CHAKI

EXT: GOP

1) Function applied for

2) ME specs

3) Oil in hotwell. *Procedure* to find out

4) Duplex filter changeover (find which filter in use)

5) centrifugal pump overhaul and inspection (what to check on the shaft?)

6)Scavenge Space inspection

7) AE routine maintenance ( from daily to 8000hrs routine)


Mmd kolkata- online mode

Internal- chaki sir

External- don't know( good guy, no cross questions)


Mep


-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


Result- coc


Fn- 4b & 6


Type of ship

Type I.G. system

P.V. Breaker & P.V.Valve

Starting interlocks

Scavange fire - indication & action

Viscosity Index .. fuel oil or l.o. which will have higher viscosity index


Hydrophore charging - how ,when , why to do

Boiler gauge glass empty - action

Purifier not picking up the RPM

What is the difference between refer room scuppers

Forgot


Fn- 6 

Fuel injector overahaull.

Tappet clearance .

Evaporator side cleaning.

Air cooler cleaning.

Crosshead clearance.

Welding equipments and procedures.


Internal AKC 

Extranal skd 

Mep

Ship type 

Auxillary engine type 

Crankcase inspection 

Measuring tool 

Dail gauge use 

Arc welding defects 

 Got coc 

Thank you guys


Kolkata mmd (online) (Motor and Mep)

Date 28/04/2021

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✌🏻
