OFFICER IN CHARGE OF A NAVIGATIONAL WATCH
Candidate Candidate’s Mariner Reference No.
Assessor Position
Vessel or School Assessor’s Mariner
Reference No.
Date
ASSESSMENT NO. OICNW-2-3I
FUNCTION: Navigation at the Operational Level
COMPETENCE: Maintain a safe navigational watch
KNOWLEDGE, UNDERSTANDING & PROFICIENCY: Watchkeeping – Thorough knowledge
of effective bridge teamwork procedures
TASK: BRM Condition II or III – Prioritization
PERFORMANCE CONDITION: On a full-mission ship simulator during an exercise at sea, and
with a bridge team in place, while navigating in congested near- coastal waters in good
visibility, and assigned duties as an officer in a bridge team, and given the following:

  1. a vessel on own ship’s starboard bow changes course and creates a risk of collision;
  2. there is insufficient water depth for own ship to turn to starboard;
  3. the diesel engines are using heavy fuel;
  4. a vessel ahead is on a reciprocal course 1.5 nm away with a CPA of 0.5 nm on the
    port side; and
  5. the GMDSS distress alarm sounds.
    PERFORMANCE BEHAVIOR: Determine the appropriate action to take…
    PERFORMANCE STANDARD:
    The candidate:
  6. assesses the situation;
  7. determines in which priority action must be taken for the safety of the vessel;
  8. recommends that the engines be slowed or stopped in sufficient time to avoid the
    collision with the vessel on the starboard bow; and
  9. after the danger of collision is over, acknowledges the distress call.

ASSESSMENT NO. OICNW-3-1L
FUNCTION: Navigation at the Operational Level
COMPETENCE: Use of radar and ARPA to maintain the safety of navigation
KNOWLEDGE, UNDERSTANDING & PROFICIENCY: Radar Navigation – parallel indexing
TASK: Determine DRM, SRM, CPA and TCPA
PERFORMANCE CONDITION: On an operational radar or radar simulator that meets the
standards of 33 CFR 164.38 and other applicable national and international performance
standards, set on the 12-mile scale, in the true motion mode, using any graphically correct
method.
PERFORMANCE BEHAVIOR: Determine the DRM, SRM, CPA and TCPA of three target
vessels.
PERFORMANCE STANDARD:
The candidate:

  1. constructs a relative motion triangle on either a reflection plotter, a maneuvering board
    or a transfer plotting sheet;
  2. obtains a DRM solution within 8 minutes and within ± 5° of the assessor’s solution;
  3. obtains a SRM solution within 8 minutes of initial range and within ± 2 knots of the
    assessor’s solution;
  4. obtains a CPA solution within 7 minutes and within ± 0.5 nm of the assessor’s solution;
    and
  5. obtains a TCPA solution within 8 minutes and within ± 3 minutes of the assessor’s
    solution
