Abstract

This paper describes the technical solution adopted for the implementation of a simulation model for maritime applications, integrated in a Matlab environment. The model will be processed by Matlab as a function and, as such, will be fully integrated in any application that requires it. In particular, it will be possible to use the simulation model within a closed-circuit optimization process capable of determining the parameters that maximize the performance of the ship design that is most able to cover given logistics requirements. The analysis includes, on the specific geometry considered, an evaluation of the seakeeping performances of the ship in the sea area covering the transportation route. The influence of adverse meteo-marine conditions reflects into an increase in the consumption and in a decrease in the average speed as compared with nominal values (in calm water). The inherent increase in running costs and the need for an incremented net weight nominal capacity to increase the probability of satisfying the specifications in terms of annual actual transportation flow are accounted for.
