The aim of this paper is to present the development of an ecological and efficient shuttle tanker structural parametric model with optimized capacity that was designed to operate at the Brazilian pre-salt region. Such a model estimates the weights and centers of the bare hull, as well as the structural weight, the center of gravity of the ship, and the moments of inertia at different dimensional, geometric, and capacity features of the ship from structural elements of the parallel middle body. These elements were automatically dimensioned at a MATLAB® environment. After an exhaustive search method through several dimensioning cases of these elements, the lowest structural weight was obtained, which satisfies the rules of classification societies. Finally, the results are shown as a response surface, which was built by means of artificial neural networks. These allow assessing the behavior of weights and centers characteristics of the ship, based on the variation of design parameters.
