The IMO Assembly, at its 18th session held in 1993, adopted resolution A.772(18) on Fatigue factors in manning and safety. This resolution provides a general description of fatigue and identifies the factors of ship operations which may contribute to fatigue that should be taken into account when making decisions on ship's operations.

Guidelines on fatigue

Consequently, at its seventy-fourth session held in 2001), the Committee approved MSC/Circ.1014 on Guidance on fatigue mitigation and management.
