How many crew members have to be employed on board? (Minimum Safe Manning)

Portugal’s Minimum Safe Manning Certificate is based on the minimum requirements of the IMO Assembly Directive 1047 (27) - principles of safe manning. The shipping company is required to comply with this directive (in particular Annex 2, 3 and 5) to propose the number of the crew, which is then evaluated by the Administration through the Technical Commission of MAR. The required or proposed number of persons depends among others on the vessel's size, the type of the vessel and on the area of operations as well as other criteria such as system maintenance and Ship Security Plan (see Annex 2 of IMO Directive).
