MINIMIZING FORCES AND MOTIONS OF LARGE OFFSHORE STRUCTURES

This paper presents a new approach to the problem of hydrodynamic optimization of large offshore structures. In combination with a 3D-wave diffraction program nonlinear programming techniques are applied to minimize forces and motions. Optimization results for a fixed monotower, a large floating buoy and a semisubmersible demonstrate the possibilities of improving hydrodynamic characteristics of offshore structures by nonlinear programming. In all cases a distinct reduction of significant force and motion amplitudes is achieved by systematic variations of geometry.
