  1. With reference to the regulations regarding watchkeeping procedures:
    (a) state the off-duty time to which a watchkeeper is legally entitled:
    (i) in any twenty-four hour period;(3)
    (ii) accumulatively over the period of one week;(1)
    (b) list SIX circumstances under which it may be necessary to increase the watchkeeping manning of the machinery spaces.(6)

(a) Off-duty time legally entitled to watchkeepers

(i) In any 24-hour period: (3)

  • Minimum 10 hours of rest in any 24 hours.
  • The 10 hours may be divided into no more than two periods, one of which must be at least 6 consecutive hours.
  • The interval between consecutive rest periods must not exceed 14 hours.

(ii) Accumulated over one week: (1)

  • Minimum 77 hours of rest in any 7-day period.

(b) Six circumstances when watchkeeping manning of machinery spaces may need to be increased (6)

  1. Restricted visibility – increased risk of collision, requiring readiness for manoeuvring.
  2. Coastal or congested waters – high traffic density demands faster responses.
  3. When manoeuvring in/out of port or narrow channels.
  4. During machinery malfunction or abnormal operating conditions – e.g. unstable generator or cooling system.
  5. During heavy weather – higher risk of damage, flooding, or machinery failure.
  6. When carrying hazardous cargoes – e.g. dangerous goods, crude oil, chemicals, requiring extra vigilance.

(Other valid points: during drills/emergencies, following UMS alarm failures, or when new/unfamiliar machinery is operating.)
