Question 1

According to SOLAS requirements, how often must abandon ship drills be conducted on board a UK-flagged cargo vessel?

Accepted Answer

Every month

Answer

SOLAS Chapter III Regulation 19.3 requires that each member of the crew shall participate in at least one abandon ship drill every month. If more than 25% of the crew have not participated in a drill in the previous month, a drill must be held within 24 hours of leaving port.

Question 2

What is the primary purpose of a thermal protective aid (TPA) carried in a lifeboat or liferaft?

Accepted Answer

To reduce heat loss from a survivor's body in cold conditions

Answer

A thermal protective aid is a bag or suit made of waterproof material with low thermal conductivity, designed to reduce body heat loss from convection, evaporation, and radiation. They are required by SOLAS for survivors who do not have immersion suits, particularly in cold water where hypothermia is the primary threat to survival.

Question 3

When launching a liferaft from a vessel in an emergency, what action should be taken if the liferaft inflates upside down?

Accepted Answer

One person should swim to the raft, climb onto the bottom, stand on the inflation cylinder side, and lean back pulling the righting strap

Answer

The correct procedure for righting an inverted liferaft is for one person to climb onto the bottom, position themselves with back to the wind and feet on the CO2 cylinder side, grasp the righting strap, and lean back using body weight to flip the raft upright. The wind assists by catching under the raft.

Question 4

What is the SOLAS requirement for the number of EPIRB (Emergency Position Indicating Radio Beacons) to be carried on a cargo ship of 500 GT or more engaged on international voyages?

Accepted Answer

One float-free satellite EPIRB capable of transmitting a distress alert on 406 MHz

Answer

SOLAS Chapter IV requires cargo ships of 300 GT and upwards on international voyages to carry at least one satellite EPIRB capable of transmitting a distress alert via the Cospas-Sarsat system on 406 MHz. It must be capable of floating free and activating automatically if the ship sinks.

Question 5

In the IAMSAR (International Aeronautical and Maritime Search and Rescue) Manual, what does the expanding square search pattern involve?

Accepted Answer

A series of straight legs of progressively increasing length, turning 90 degrees after each leg

Answer

The expanding square search (SS) pattern begins at the datum (last known position) and proceeds outward in a series of legs, turning 90° to starboard (or port) after each leg. Each pair of legs is longer than the previous pair by the track spacing distance. It is most effective when the datum is well established.
