MCA Certificate of Competency Watchkeeping Principles and Procedures Questions and Answers — Questions and Answers
Question 1: According to the principles of safe watchkeeping as outlined in STCW Code Section A-VIII/2, which of the following conditions must be met BEFORE the relieving Officer of the Watch (OOW) formally assumes responsibility for the watch?
- The outgoing OOW must have completed all logbook entries for their watch.
- The relieving OOW must be satisfied that they are properly prepared and have personally assessed the ship's position and intended track. (Correct answer)
- The Master must be present on the bridge to witness the handover in all circumstances.
- All scheduled navigational warnings for the next 12 hours must have been received and plotted.
Correct answer: The relieving OOW must be satisfied that they are properly prepared and have personally assessed the ship's position and intended track.
STCW Code Section A-VIII/2 states that the relieving officer shall not take over the watch until they are satisfied that they are properly prepared and have personally satisfied themselves regarding the ship's position, intended track, course and speed. The responsibility lies with the relieving officer to be content with the situation before accepting the watch.
Question 2: You are the Officer of the Watch (OOW) on a UK-flagged vessel in the open sea with clear visibility. The Master's standing orders state he should be called if visibility deteriorates to less than 3 nautical miles. You observe a large bank of fog approximately 10 nautical miles ahead, which the vessel is approaching at 15 knots. What is the most appropriate action?
- Wait until the visibility drops to exactly 3 nautical miles before calling the Master.
- Alter course to avoid the fog bank without informing the Master.
- Reduce speed to 5 knots and enter the fog, only calling the Master if another vessel is detected.
- Call the Master immediately to inform him of the approaching fog bank and your observations. (Correct answer)
Correct answer: Call the Master immediately to inform him of the approaching fog bank and your observations.
Good seamanship and the principles behind Master's Standing Orders require the OOW to notify the Master in ample time before a hazardous situation develops. Waiting until the limit is reached removes the Master's opportunity to assess the situation and provide guidance beforehand. Informing the Master early demonstrates proactive bridge management.
Question 3: In accordance with SOLAS Chapter V, Regulation 26, which of the following steering gear tests and checks must be carried out by the ship's crew within 12 hours before departure?
- A full pressure test of the hydraulic system to 1.5 times the maximum working pressure.
- A complete disassembly and visual inspection of the rudder stock bearings.
- Verification of the operation of the main and auxiliary steering gear and the remote control systems. (Correct answer)
- An emergency steering drill involving a simulated total loss of bridge control.
Correct answer: Verification of the operation of the main and auxiliary steering gear and the remote control systems.
SOLAS V/26 explicitly requires that within 12 hours before departure, the crew must check and test the operation of the main steering gear, the auxiliary steering gear, and the remote steering gear control systems, among other items. The other options describe major maintenance, surveyor tests, or less frequent drills.
Question 4: According to the principles of passage planning widely adopted on UK-flagged vessels and recommended by the IMO, which sequence correctly identifies the four key stages of a voyage plan?
- Execution, Monitoring, Appraisal, Planning
- Briefing, Execution, Debriefing, Recording
- Appraisal, Planning, Execution, Monitoring (Correct answer)
- Planning, Appraisal, Monitoring, Execution
Correct answer: Appraisal, Planning, Execution, Monitoring
The four stages of passage planning, as defined by IMO Resolution A.893(21), must follow a logical sequence. First, all relevant information is gathered (Appraisal). Second, the detailed berth-to-berth route is planned (Planning). Third, the plan is carried out (Execution). Fourth, the vessel's progress is continuously checked against the plan (Monitoring).
Question 5: The Master of a UK-flagged vessel has determined that the Officer of the Watch (OOW) can act as the sole lookout during daylight hours in open water with good visibility. In which of the following circumstances would this arrangement become immediately inappropriate, requiring a dedicated lookout to be posted?
- When the vessel is more than 200 nautical miles from the nearest land.
- When the OOW is required to undertake duties that would interfere with keeping a proper lookout, such as chart corrections. (Correct answer)
- When the vessel takes a licensed pilot on board.
- At the moment of sunset.
Correct answer: When the OOW is required to undertake duties that would interfere with keeping a proper lookout, such as chart corrections.
COLREGs Rule 5 requires a proper lookout to be maintained at all times. The STCW code clarifies that the OOW may be the sole lookout in certain conditions, but a fundamental principle is that the lookout must be able to give their full attention to that duty. If the OOW is engaged in other tasks that prevent this, a separate lookout must be posted.
Question 6: A UK-registered vessel has a local, fully licensed pilot on the bridge for port entry. According to established maritime practice and UK law, which statement accurately describes the command relationship?
- The pilot assumes full command and legal responsibility for the vessel's navigation.
- The Master and pilot share joint legal responsibility for the vessel's safety.
- The Master retains ultimate command and responsibility for the vessel, with the pilot acting in an advisory capacity. (Correct answer)
- The Officer of the Watch must only accept orders from the pilot, not the Master, during pilotage.
Correct answer: The Master retains ultimate command and responsibility for the vessel, with the pilot acting in an advisory capacity.
It is a fundamental principle of maritime law that the Master is at all times in command of their vessel and responsible for its safety. The presence of a pilot, who provides local knowledge and expertise, does not relieve the Master or OOW of their responsibilities. The pilot's role is to advise the Master.
