Logística do escoamento da produção de petróleo de plataformas offshore via transporte naval

Abstract

Currently, Brazil has 113 petroleum platforms, been 79 fixed and 34 floating, with daily production capacity of 2,1 million barrels of oil. Given this production is necessary a strategy for the efficient distribution of oil to refineries, where it will be processed and refined. Oil from the platforms is transported to refineries through pipelines or ships, with much of the operational cost of production is due to transport. For this reason the minimization of the cost of transport is extremely important. This work has for objective, using the technique of mathematical programming (linear mixed integer programming - LMIP), reduce costs arising from transport system. The model consists of a heterogeneous fleet of ships, which have compartments that can only be occupied by a single type of product on each trip. Initially are generated all possible routes and then selected the vessels, associated with their routes in order to attend the demand of refineries and the need for removal of oil in the storage tanks of the platforms. For the implementation of the model was used the software GAMS (General Algebraic Modeling System), together with the method of CPLEX optimization. The results were satisfactory.
