With the growth of the oil sector in the world and Brazil, activities in the offshore environment show that there is a range of difficulties in logistics operations in this production environment. Given a large number of variables and data used in the activities that integrate the entire operational chain in the offshore area, operational research models can be used to find optimized solutions. For these cases, it is necessary to use a multicriteria analysis, which can then be considered economic factors, sustainable factors among others. Thus, this work seeks to contribute to the scheduling of three strategies of the selection of the navigation speed of the fleet of PSVs (Platform Supply Vessels), boats that supply the demands of the Maritime Units, based on economic, environmental and crew welfare, analyzed by a multicriteria model. To achieve this goal, a decision support tool called APOLO was used, which combines a discrete event simulator with a PSVs heuristic for cargo and marine units allocation. The ELECTRE III model was selected for the multicriteria analysis, then the relevant indicators for the problem were defined. As a result, we obtained the third strategy as the winner, presenting the agreement indices and the preference relations between the navigation strategies. Thus, the results obtained by the model can contribute to take decisions. The multicriteria method was relevant and applicable to decision-making processes that involve subjective and quantitative variables.
