STCW Watchkeeping Duties 5

Question 1

During a night watch in open ocean, what is the recommended interval for taking manual position fixes when the vessel is on autopilot?

Accepted Answer

At intervals appropriate to the navigational situation and proximity to hazards

Answer

STCW requires the OOW to take position fixes at intervals appropriate to the navigational situation — more frequently near hazards, less so in open ocean.

Question 2

An OOW observes a vessel exhibiting two red lights over a white light at night. What type of vessel is this?

Accepted Answer

A vessel not under command

Answer

Two red lights in a vertical line indicate a vessel not under command (NUC), meaning she cannot maneuver and other vessels must keep clear.

Question 3

What action should the OOW take when the vessel enters a declared Emission Control Area (ECA)?

Accepted Answer

Switch fuel to low-sulfur compliant fuel as required by MARPOL Annex VI

Answer

Upon entering an ECA, the OOW must ensure the vessel switches to compliant low-sulfur fuel per MARPOL Annex VI requirements and document the switchover.

Question 4

If the gyrocompass fails during a navigational watch, the OOW should immediately:

Accepted Answer

Switch to the magnetic compass and notify the master

Answer

When the gyrocompass fails, the OOW must immediately switch to the magnetic compass (applying deviation and variation) and notify the master.

Question 5

According to STCW, how must the OOW respond if a crew member reports a man overboard situation?

Accepted Answer

Immediately alter course and execute a man overboard maneuver, sound the alarm, and notify the master

Answer

Man overboard requires immediate action: execute the MOB maneuver, sound the alarm, mark the position, and notify the master simultaneously.
