OICNW-2-1D

Determine risk of collision

Condition

On a ship underway, a full mission ship simulator, or using approved laboratory equipment, and using a gyro-compass repeater and an azimuth circle, bearing circle, alidade, or other device for taking bearings, and a marine radar or ARPA meeting IMO performance standards set on the 12 mile scale and the targets more than 8 miles away.

Performance requirement

Behavior Standard
The student will: During assessment, the student shall, at a minimum:

Determine if risk of collision exists with approaching meeting, crossing and overtaking vessels.
  1. Two visual bearings of an approaching vessel are taken using an azimuth circle, bearing circle or alidade to determine if the bearing to the approaching vessels is appreciably changing.
  2. Two electronic bearings of an approaching vessel are taken on a radar or an ARPA to determine if the bearing to the approaching vessels are appreciably changing.
  3. Correctly determines if risk of collision exists.

Note: This assessment supports KUP OICNW-A2.1, and is assessed in MT-4253 Watchkeeping using Full-Mission Bridge Simulator.
