Fuel, Ballast Operations. Test 3 – Online Maritime Tests

What to do if Your ship receive HFO with high density, from the last bunkering, to obtain the best purifying result?

Increase the speed of the purifier (RPM).
You start the purifier with a smaller disc.
According to the nomograms You select a gravity disc with larger hole diameter.
This make no difference for the result.

For ships not fitted with a sludge burning incinerator, the sludge tank capacity shall be directly proportional to _____

the size of the vessel.
the number of purifiers fitted on board times the maximum range of the ship.
the amount of fuel purified for daily consumption times the maximum period between voyage ports.
the total horse power (or kWatt) generated in the engine room.

Every ship above 400 tons gross shall be provided with tank(s) of adequate capacity to receive oily residues or sludges such as those resulting from _____

All oil leakages in the engine room inclusive of these.
diesel oil leakages from purification, main and auxiliary engine fuel leakages.
lubricating purification and crankcase leakages from machinery and stern tube leakages.
heavy fuel oil purification leakages, lantern and scavenge spaces leakages and drainages from engines.

During UMS rounds, a duty engineer notices that the fuel oil overflow observation glass is full of oil. Should he:

Make a sounding of the F.O. overflow tank and decide if there is enough capacity to leave it until the following morning.
Call a motorman and have him sound the FO overflow tank periodically during the night.
None of the listed alternatives.
Stop all F.O. transfers immediately, and inform the CE.

Written information must be available each time a ship carries out bunkering operations inclusive the titles. This information includes the names of the persons engaged in bunkering operations. Which persons ?

The responsible person in charge, the duty engineer, the engineer in charge of bunkering and the stand-by team on deck.
The responsible person in charge, the engineer officer in charge of bunkering in the engine room and the person(s) assigned on deck.
The chief engineer, the duty engineer and the duty officer.
The chief engineer, the engineer officer in charge in the engine room and the petty officer on deck.

Written information must be available each time bunkering operations are carried out. This should include information about reporting oil spills and provide contact details for which of these organisations?

I, II, III, VI, VII, VIII
II, III, IV, VI, VIII, IX
I, III, IV, V, VIII, IX
III, IV, V, VI, VII, IX

To avoid overbunkering and/or oil spill, preparation has to be done, and a check list made, to ensure that nothing has been forgotten. Which point on this list do you consider as most important (one answer only)?

Open blank flanges on bunkering manifold in good time before bunkering barge arrives
Connect a water hose to the water on deck line, so an oil spill can be hosed quickly away if it come on deck
If you are taking bunker on the port side of the vessel, check that the starboard manifold is closed and blanked off
Open all plugs in sounding pipes in good time before bunkering starts

When you are going to take bunker oil, it is important to know what space is available in your tanks, and to do a safe bunker operation. What will you prefer?

Base available space on an average calculation of the weekly soundings since last bunkering
Base available spaces in tanks on the accounting of used fuel in the log-book
Do a sounding on the tanks where the remaining fuel on board are located
Do a complete sounding of all bunker tanks

What do you have to ensure when pumping from double bottom tanks to day- and settling tanks?

That the day tank is never left half empty when relieved from watchkeeping duties.
That the pump is stopped in time to avoid overflowing.
That the pump has correct suction from the settling tank.
That the pump is running continuously without noise.

Written information must be available each time a ship carries out bunkering operations. This information must include the following _____

the ventilation and overflow system of each tank and the bunker rate in tons per hour.
the specific gravity of the oil and the level at which bunker tanks are to be closed.
the procedures for topping off tanks and the bunker slow down rate.
the bunkering rates, procedures for topping off tanks and the level at which bunker tanks are to be closed.
