A very nice and easy guy to talk to, and he was very reasonable with any mistakes that were made. Anytime I did not have a clear answer to something, he would come back to it later and explain the question from a different angle to see if that jogged any memories. He would also explain the correct answer if I got something wrong. Told me that since I had been working as a 2nd Engineer for a few years already that my engineering knowledge should be fine and that he would mostly be concentrating on legislation. I’ve maybe missed a few questions but most of them are here.
1. What do you know about DMLC1 & DMLC2
2. Talked about MLC2006 and its requirements, such as work agreements, work hours etc.
3. Asked about hull survey requirements, such as how many years between surveys, when in-water surveys could be carried out etc.
4. Talked about Annex 6, particularly NOX. He wanted to know the contents of the NOX Technical file.
5. Fuel quality – Where would you find the sulphur content of fuel? Wanted to hear about BDN, and also that fuel samples are sent away for lab testing after bunkering for further checks.
6. How can you test LO onboard?
7. Engine lub. Oil is showing low viscosity, what could be the causes? (Fuel, cooling water contamination etc)
8. Where would the most likely source for fuel in LO be?
9. Asked to list the things a Bunker Delivery Note contained, particularly looking for the declaration from the supplier that the fuel is compliant with annex 6.
10. List the certificates required onboard.
11. Talked about preparations for drydock at various stages, such as at 12 months, 3 months, week before etc. Wanted to hear about drydock specs, organising parts/spares, delegating work etc.
12. Talked through the first inspection of a hull after entering drydock – Started at the front and worked my way aft. He asked about percentages of wastage for anchors & chain for them to be condemned, reasons for having a doubler-plate on bilge keel, would it be acceptable to remove a damaged section of a bilge keel and not replace it (No).
13. Asked how to check propellor drop – Where the measuring point is, what tool to use. Also asked if it is ok to use any type of gauge. I said that a dedicated poker gauge is usually kept with the ship and this one must be used each time with the propeller in the same position at each measurement, and he was happy with that.
14. Talked about checks on propellor – Means of testing for cracks, ways of fixing cracks, how long can a crack be before that section must be cropped out and replaced.
15. Rudder checks, such as clearances and removing plug.
16. Shaft checks – He went into methods of non-destructive testing to use to find cracks in a shaft. He wanted to hear ultrasonic.
