Introduce Yourself ( Again after doing the same)
Started with NO IDEA for 1st 2 questions were some definitions had never heard before. 
What is Horn of the Ship.
Bilge Keels uses, construction,reason.
How do u know the ship is stable, Define Metacentric Height,
Why free board of Tanker is lesser that other ships.
Define PV Valve ,Functions, How many P Valves u had on ur ships, How many cargo Tanks( Answered 7 PV Valves and 14 Tanks) Then question why half the number of PV Valves than Tanks.
How does a PV Valve work at day and night does it work the same way if not what ‘s the difference(Took some time to answer this in morning the temperature of the atmosphere and sea ‘s much much higher than at night so in morning due to high ttemperature there ‘s generation of vapour at this temp leading to high pr inside tanks and PV Valves work to relive them, though at night the temp falls and it works to relive vaccum in Tanks ,,,,,,, was happy with the answer said nice)
Draw Mast Riser, How is Mast Riser connected to all tanks, How is the Vapour Emitted from Mast Riser how is the Pressure given to the vapours.


Tempeature of Engine cooling water rises , reason’s.
What is Boiler Blow Down , How do u do it and How do u know that the Blowdown is Finished.
What is single pass, Double Pass and Triple Pass
Draw It..
What Cooler u had for Piston Cooling. What is it For jacket.Materials for both Tube and Plate Type.
Why Plate type for Jacket and Tube Type for Fresh Water.
What is Peak Pressure, How do u calculate it.
How do u calculate power of engine.
Draw Power card.
Had earlier used the formula IP = PLAN/60000 he asked where does that 60000 come from and what is that.
That’s all I remember in this section.


Single Phasing.
How do u take an Incoming A/E on load. How is voltage regulated of the same and how is the frequency adjusted.what happens when u use the speed droop setting of the governor.
Constructional difference between A.C and D.C motor and working.
While using E/R Crane power fails what will happen to the load attached.
How does the same happen.
Purifier Motor Rotates in the opposite direction.Reasons.
Insulation Breaakdown..(That’s all I Remember again)

Function – 6
Clearence of Bottom End Bearing A/E.How do u take it , values( Had answered this one correctly but din say the isolation of A/E so they were not happy with the answer) 
Lowering of Piston in Liner Procedure.
Suction of REF Compressor Iced up Reasons.

i am posting only dangerous questions

1.correct definition of displacement as in solas...he wants the exact word by word definition in solas.
2.wat is the nominal tightening torque of M16 bolt? wil we make sure that the propeller wont slip the propeller shaft in keyless propeller.he asked me to draw..which i drew in a dirty way...;)
4.wer is the metacentre in a sunken ship or a sinking ship..(i bluffed it coincides with the centre of gravity)
5.wats the pressure setting of a pv breaker and a pv valve...he needs the values..
6.difference between pressure gauge in ac plant and normal air compressor..

viva lasted only 15 min..i answered most of the questions but he said to attend mep again..sayed am missing something in i need to learn that "missing" things...;)

‎22nd Feb 2012
Surveyor - Wankhede + Mishra
Function - 3

Q1. what is the speciality of Container vessels
A1. i mentioned the Tortion box and got grilled about WHY it was put there OR when we strengthen a ship, by adding a strength,, what exactly are we doing ??.... He finally wanted to hear "to increase the Section Modulus of the Ship" Section modulus, as told by Wankhede sier has something to do with the Moment of inertia or something,, do look it up...

for the tortion box i drew the cross section of the vessel,, so he asked me questions on the construction of the container cargo hold also.. eg. the securing arrangements for the containers while in the hold etc...

Q2. Draw the Cross section of DB tank you have seen,, i drew the Longitudinally framed,,, but forgot to label the Scallops around the bottom (and inner bottom) longitudinals,,, and he asked WHY is scallop this there ??.. He later told me that the Solid floor and the longitudinal are joined by a pressure plate thats welded in place,...

then Mishra sir took the remaining safety Marpol and Solas
Marpol,, i told him complete names of all Annexes,, and no further questions on Marpol
Solas,, how many chapters,, name them,, 
what is there in the 11th chapter,...
including 11.1 and 11.2
in 11.1 - Continuous Synopsis Record, Automatic Identification System, (not sure) Long Range Identification and Tracking...
this is because,, AIS is being implimented in India this year,, in light of Mr. Kassab's actions in 2008.

CO2 weekly checks,..
i told him all simple ones...
but he wanted to hear,, the opening of the CO2 release cabinet door, and activation of the alarms,,.. and i told him only C/E did it during the monthly drill,, he was like this is wrong, on the part of your superiors and stuff.....

then a few things about the CO2 monthly and yearly checks,, which you can easily find in the books,,, thats exactly what i answered....

Result : PASS... :D

Thanks a lot guys....
keep up the good work and keep helping each other out....
Best of luck on your endeavors...

Cheers !!... :D
