What is meant by 'Load On Top'?

Loading part cargo in one port, then loading same type of cargo 'on top' in the next loadport
Loading cargo 'on top' of the oil and cargo residues in the sloptanks
Loading tanks through the tank hatch
Loading part cargo in one port, then loading different type of cargo 'on top' in the next loadport

Which of the following items DO NOT have to be noted in the Oil Record Book ?

Which of these factors will NOT affect the necessary time needed to settle oil on top of the water in the sloptank?

When we are taking 'ullages', what are we really doing?

What is the purpose of the 'small diameter line' on a crude oil tanker?

Make it possible to decant water overboard from a sloptank without risk of contamination from the main cargo lines
Make the stripping easier during Crude Oil Washing
Make it possible to discharge slops ashore without using the main cargo lines
Make it possible to drain to shore the remaining cargo in the ship's lines and pumps, after the discharging is completed

The decision to abort a proposed or ongoing ship to ship mooring or cargo transfer operation rests solely with:

The Sen.Off.Deck of the manoeuvring or offtake vessel.
The Pilot, if one is present on either ship.
The Sen.Off.Deck of the constant direction or anchored vessel which is to discharge the cargo.
Either of the Sen.Off.Deck if he feels the situation is heading out of control due to bad weather, bad manoeuvring, or for any other reason.

You wish to use the slop tank for the source of driving fluid for COW. Which of the following should be done before starting:

Discharge the slop tank completely and refill it with oil from a full cargo tank
Discharge the slop tank completely and refill it from another tank from which the bottom 1m ullage has already been discharged
Discharge the bottom 1m of ullage from the slop tank
Start the washing as soon as the tank to be washed is ready

During crude oil washing of No: 1C tank the duty deck officer reports that the oxygen reading in the tank is 9% . What should you do ?

Carry on with the washing as the reading is below 11%
Carry on and ask the engineers to check the inert gas system
Stop the washing process and not resume until the oxygen content in the tank is below 8%.
Stop the washing process and not resume until the oxygen content in the tank is below 2%

During discharging of crude oil the inert gas system fails totally. Should you:

Stop all cargo operations and close the deck IG line isolating valve
Stop discharging and wait for the I.G. to start before resuming discharge
Carry on discharging until the positive pressure in the tanks has dropped to a minimum and then stop
Carry on discharging and advise the terminal that you have I.G. problems
