Which of the following information is correct considering the use of checklists?
Checklists are only required when performing a ship to ship transfer.
Checklistis should not be mixed.
Both checklists from ISO and IAPH can be used together.
The term bunkering comes from the word "bunker" as in the early days of shipping, the coal used to fuel the ships was stored in a space called the bunker.
True.
False.
Match the following zones to their correct description. Hazardous Zone:
In this zone risk of a flammable atmosphere is present at all times, this is an area directly around the bunkering area.
This zone extends beyond the hazardous zone and has further precautions due to the nature of LNG if spilled.
This zone ensures passing traffic does not affect the safety of the operation. Assistance may be required from the port to enforce.
This zone is where other shipboard activities and SIMOPS are monitored to ensure there is no encroachment of the safety zone.
This zone is a large area that is intended to protect public access as per local regulations.
Match the following zones to their correct description. Safety Zone:
In this zone risk of a flammable atmosphere is present at all times, this is an area directly around the bunkering area.
This zone extends beyond the hazardous zone and has further precautions due to the nature of LNG if spilled.
This zone ensures passing traffic does not affect the safety of the operation. Assistance may be required from the port to enforce.
This zone is where other shipboard activities and SIMOPS are monitored to ensure there is no encroachment of the safety zone.
This zone is a large area that is intended to protect public access as per local regulations.

The IMO 2020 limit reduced the amount of sulphur in fuel used on board (outside emission control areas) to which of the following percentages?
0,5 %.
3,5 %.
5 %.
10 %.
Which of the following describes LNG?
Colourless.
Odourless.
Black in colour.
Non-corrosive.
Toxic.
A closed system can only be practised if which of the following components are in place?
LNG articulated rigid piping and certified hoses, valves and couplings.
Suitability constructed tanks that allow pressure build-up within a safe range.
An ESD system which is connected to both the supplier and receiver of LNG.
Drip or insulated trays.
How can the "dry disconnect" process be achieved?
By draining or inerting the system, so that no LNG vapour is present before disconnection.
By top spraying and filling in the receiving tanks to provide cooling and avoid the occurrence of BOG.
Using dry connect and disconnect couplings, which close in any LNG vapour before disconnection.
What are the disadvantages of a ship to ship transfer?
