Analysis of offshore systems in random waves
This paper addresses the analysis of the motion of floating offshore systems in waves. The focus lies on different approaches for the determination of probability density functions. The analysis of the dynamical behavior of systems in ocean waves is an important part in offshore engineering. These structures involve components with very distinct nonlinear characteristics which affect the dynamics. The systematic analysis of the nonlinear dynamics of floating structures is generally facilitated by additional assumptions, such as waves modeled by periodic functions or linearizations of parts of the equations of motion. These assumptions make conclusions about the first passage time or upcrossing probabilities difficult or even impossible. This paper addresses different approaches for the description of random forces acting on floating structures and for the analysis of the resulting motion.
