Seafarer fatigue

For seafarers fatigue is most likely to be caused by overwork, long and irregular hours resulting in lack of sleep. But the situation will be made worse by many other factors often faced by seafarers, for example:

  • Loneliness, lack of communication with home, social interaction etc
  • Isolation
  • Safety issues with the vessel
  • Issues with non-payment of wages
  • Inadequate and/or poor-quality food
  • Risks such as piracy
  • Repatriation delays following completion of contracts

According to national rules, the employer must guarantee that crewmembers stick to maximum working hours or minimum resting time:

  • The maximum working hours must not exceed 14 hours in any 24-hour period and 72 hours in any 7-day period
  • The minimum resting time cannot be less than 10 hours in any 24-hour period and 77 hours in any 7-day period
  • You can divide the hours of rest into a maximum of two parts. If you split the rest, one of the two rest periods must last at least 6 hours and the interval between consecutive rest periods cannot exceed 14 hours.
