The Oil & Gas sector relies mainly on the maritime transport to ship large volumes of petroleum and products. In this sense, this paper proposes a mixed integer linear model whose objective is to determine the coastal navigation fleet size and the type of vessels to transport clean petroleum products of real company. The model’s outcome helped programmers define how many ships are actually required to meet the commitments undertaken within a pre-established planning horizon. Comparing the model’s result with the actual number of vessels available for programming, one can eventually release ships to make other journeys, thus avoiding the hiring of ships in Voyage Charter Party for this last purpose. It is also possible to reduce the demurrage in periods of low movement, when the fleet contracted becomes oversized.
