Abstract

A position keeping control system of a floating offshore oil platform is studied for higher operation efficiency under environmental conditions. An algorithm for the system is constructed by using modified nonlinear programming theory based on the mixed penalty method and the quasi-Newton method, because a floating offshore platform has nonlinear characteristics of motion and has constraints of thrusters. The proposed algorithm is applied to the optimal thruster force determination of a semisubmersible floating offshore platform
