Vessel Stability and Fire Safety Quiz

What could be the effect on the vessel based on this data?

• The vessel can probably be saved, if further flooding can be stopped

• The slowing is only temporary and the vessel will probably suddenly capsize or plunge from loss of stability due to change in the waterplane area

• The vessel will suddenly flop to the same or greater angle of list on the other side and may capsize

• The vessel will continue to slowly list and/or trim due to the free surface effect and free communication effect

Which spaces are required to be segregated from cargo tanks carrying grades A, B, C, or D cargoes?

• Cofferdams

• Navigation spaces

• Enclosed deck spaces

• Pump rooms

Which ship's tanks are particularly important for trimming the ship?

• deeps

• peaks

• settlers

• domestics

When to considered that a vessel is "listed"?

• inclined due to an off-center weight

• down by the head

• down by the stern

• inclined due to the wind

The vessel has run aground and is touching bottom for the first one-quarter of its length. What is the LEAST desirable method from the standpoint of stability to decrease the bottom pressure?

• Shift deck cargo aft

• Pump out the forepeak tank

• Discharge forward cargo

• Flood and after double-bottom tank

Which tank on board a ship causes relatively freer surface effect if kept slack?

• Empty tanks on the aft side.

• Full tanks on the forward side.

• Partially filled tanks on any sides.

• Partially filled tanks on the forward side.

The vessel is damaged and is listing to port. The rolling period is short. There is sufficient freeboard so that deck edge submersion is not a problem. What corrective action should be taken first in regards to the vessel's stability?

• jettison topside weights to reduced KG and KB

• press up any slack double bottom tanks to add weight low down

• Flood any empty double bottom tanks to add weight low down

• shift any off-center weights from port to starboard

How can radiation spread a fire?

• by the transfer of heat across an unobstructed space

• by the heated gases flowing through ventilation systems

• by heat of a fire through the ship's metal

• by burning liquids flowing into another space

Which of the hazards listed is of a primary concern, other than fire damage, associated with a class C fire?

• Explosion

• Susceptible to reflash

• Deep seated fire

• Electrocution or shock

Besides heat, fuel, and oxygen, which of the following is necessary for a fire to exist?

• Thermal action

• Chemical occlusion

• Pyrotechnical reaction

• Chain reaction
