Working on ships is not an easy job, and addressing fatigue among seafarers is a major concern. Per IMO, Work hours are defined as the number of hours for which a seafarer is required to be on duty, on account of the vessel where he/she is employed, or to be at the disposal of a superior outside the crew’s quarters. Hours of rest include the time spent outside of work hours, which does not include intermittent breaks.

Operations like lifeboat drills, firefighting drills, and drills prescribed by national laws and regulations should be conducted in a manner to ensure minimum disruption of the rest period. The number of ship working hours and hours of rest for crew members in all positions must be displayed in a place of easy accessibility for the purpose of informing the seafarers in due time.

The master can suspend the schedule of work hours and hours of rest in situations of vessel distress when a seafarer is required to perform certain duties until normal conditions are restored. On return to normal conditions, seafarers involved in work during the period of distress should be granted a rest period to prevent the buildup of fatigue on the ship.
