... filtering. In the situation of a relatively narrow directional spread of intense waves the free wave kurtosis may possess the value comparable with the bound wave kurtosis, exhibiting abnormally extreme sea states. In such situations the evidence of emergence of coherent wave groups in the 3D fields...

.... On the other hand, a control system with fast response speed is needed for the MPPT to track wave changes quickly. In this paper, a system model of the LMMHD WEG is analyzed firstly, and an MPPT control strategy that can automatically identify the sea state and can automatically realize current sharing...

... it to detect a line failure. The accuracy of the system is demonstrated using numerical simulations for an FPSO in various sea states, where a line break occurs at one time instant during the simulation. INTRODUCTION A moored floater is a 6-DOFs system where the loads are stochastic environmental loads...

... of an offshore structure exposed to Morison wave loading can be approximated by the response of an equivalent finite-memory nonlinear system (FMNS). Previous investigation shows that the developed FMNS models reduce the computational effort but the predictions are not very good for low intensity sea states...
