Question 1

You are due to take the 0000-0400 watch. You have had only 4 hours sleep in the last 24 hours due to port operations. Are you fit for watch? What should you do?

Accepted Answer

FITNESS FOR WATCH — FATIGUE ASSESSMENT: STCW CODE A-VIII/1 Para 2: "All persons who are assigned duty as officer in charge of a watch or as a rating forming part of a watch shall be provided a minimum of 10 hours of rest in any 24-hour period." With 4 hours sleep in 24 hours, you are below the STCW minimum. LEGAL POSITION: you are NOT legally compliant with rest hours. Taking the watch in this state is potentially a violation of STCW. WHAT TO DO: (1) REPORT TO MASTER: you must report your condition to the master before the watch. This is not optional — STCW Regulation VIII/1 and ISM Code obligations require officers to report fitness concerns; (2) MASTER'S DECISION: the master must then either: (a) arrange a replacement OOW; (b) take the watch personally; (c) make a formal exception entry in the rest hour records if port operations genuinely required the deviation (some exceptions are permitted in STCW for port operations); (3) STCW EXCEPTION: exceptions are allowed where "the nature of the voyage or operational needs" require it — but must be documented and cannot be routine; (4) HONESTY: do NOT take the watch and assume you will be fine. Fatigue-impaired watchkeeping is dangerous and you bear personal legal liability if an accident occurs; (5) LOG: the master should log the exception and the compensatory rest arrangement. Fatigue and watchkeeping: this is a fundamental safety competency question. The 2010 Manila Amendments to STCW introduced stronger requirements for fatigue management precisely because it was identified as a major accident cause. The duty to report: STCW Code A-VIII/1 creates an obligation on watchkeepers to report if they are not fit for duty. This is a professional and legal obligation — not optional. The master's responsibility: once informed, the master must act. A master who forces a visibly fatigued officer to take a watch, and an incident occurs, faces serious legal consequences. The port operations exception: STCW does allow exceptions to rest hour requirements in port (when operations require continuous presence). But the exception must be documented, must be for genuine operational necessity, and cannot be used routinely as a way of ignoring rest requirements. After port operations, adequate compensatory rest before the next sea watch is required. Professional reporting: option C is exactly the wrong culture. ISM Code promotes a "just culture" where safety concerns are reported without fear of blame. An officer who admits fatigue is acting professionally and correctly.

Question 2

Describe the minimum rest hours requirements under STCW 2010 for officers on a sea watch.

Accepted Answer

STCW 2010 MINIMUM REST HOURS (Regulation VIII/1 and STCW Code A-VIII/1): MINIMUM REST: seafarers must have minimum rest of: (a) 10 HOURS REST in any 24-hour period; AND (b) 77 HOURS REST in any 7-day period. ALTERNATIVE: maximum HOURS OF WORK: (a) 14 hours work in any 24-hour period; AND (b) 72 hours work in any 7-day period. VESSELS MUST USE EITHER rest system OR work system (not mix-and-match). REST HOURS RULES: (1) Rest may be divided into no more than TWO PERIODS — one of which must be at least 6 hours uninterrupted; (2) The interval between consecutive rest periods must not exceed 14 hours; (3) EXCEPTION: drills and emergency procedures — musters, fire drills, abandon ship drills — must be conducted to minimise disruption to rest but will not be counted as disturbances requiring compensatory rest, UNLESS they interrupted the 6-hour minimum rest period; (4) RECORDS: rest hour records must be maintained in the prescribed form and signed by both master and seafarer. Must be available for PSC inspection; (5) UK MGN 353: MCA guidance on rest hours — UK flagged vessels must comply with STCW AND MLC 2006 rest requirements (MLC is broadly the same). STCW rest hours 2010 (Manila Amendments): the 2010 amendments strengthened the rest hour requirements and added the requirement for records. The 10/77 system: 10 hours rest per 24 hours, 77 hours per 7 days. The 6-hour minimum unbroken rest period: this cannot be split. A seafarer who gets two 5-hour rest periods does NOT comply — one period must be at least 6 hours. The 6-on/6-off watch system trap (option D): a 6-on/6-off system gives only 12 hours rest in 24 hours — which exceeds the 10-hour minimum. However, the 6 hours off watch is NOT 6 hours rest — travel to/from bridge, meals, personal hygiene all reduce actual rest time below 6 hours. Many vessels use 4-on/8-off systems to give adequate rest. PSC inspection: Port State Control officers routinely inspect rest hour records. Falsified or deficient rest records are a major finding. Vessels have been detained for rest hour violations. The fatigue link: MAIB and other maritime accident investigators have identified fatigue as a contributing factor in a significant percentage of maritime accidents. Proper rest is a safety issue, not just a regulatory one.

Question 3

A deck rating on your watch tells you he has been on duty for 18 hours continuously due to mooring operations and a cargo watch. He asks if he must continue his sea watch. What are his rights?

Accepted Answer

MLC 2006 REST HOURS — RATING ON WATCH: MLC 2006 Standard A2.3 provides the same rest hour requirements as STCW: minimum 10 hours rest in any 24-hour period, minimum 77 hours rest in any 7-day period. AT 18 HOURS CONTINUOUS DUTY: the rating has already exceeded the 14-hour maximum work limit for any 24-hour period (MLC maximum is 14 hours work). He is legally entitled to rest. HIS RIGHTS: (1) He has the right to refuse watch duty — he is in breach of rest hours through no fault of his own (operational requirements); (2) The OOW cannot require him to stand watch in this state; (3) ESCALATE TO MASTER: this is above the OOW's ability to resolve alone. Call the master; (4) MASTER'S OBLIGATION: the master must: arrange an alternative watch-stander; or take the watch personally; and must document the rest hour exception in the rest records; (5) MLC REST RECORD: an exception entry must be made with the reason. The rating must sign the record; (6) IMMEDIATE REST: the rating should be sent to rest as soon as a replacement is available; (7) SAFETY CONSIDERATION: an 18-hour continuous worker is severely fatigued. Keeping them on watch creates safety risk for both the vessel and the rating personally; (8) COMPANY: if the operational demands routinely cause rest hour violations, this is an ISM non-conformity to report to DPA. MLC 2006 rest hours: apply to all seafarers regardless of rank. The 10/77 system applies to both officers and ratings. 18 hours continuous work is a serious violation of MLC and STCW. Port + sea hours: all hours of work count toward the 14-hour daily maximum — whether the work is port operations, mooring, cargo watch, or sea watch. The "port exception" myth (option B): while STCW does allow limited exceptions for port operations (documented exceptions in the rest records), these are for situations where the operation genuinely cannot be deferred. They do not mean ratings have unlimited work hours in port. Port exceptions must still be documented and compensatory rest given. Option D (personal responsibility): legally and professionally wrong. The master and company are responsible for ensuring adequate manning so that rest hours can be observed. If the vessel is under-manned, leading to chronic rest hour violations, this is the company's problem, not the individual seafarer's. PSC inspection: port state officers regularly check rest hour records and interview crew. Falsified records or systematic rest hour violations lead to vessel detention.
