... stagnation flow channel flow motion control offshore installations Spars have become an “industry solution” for the deepwater Gulf of Mexico. Yet there continue to be technical issues with the spar concept pertaining to vortex-induced motions (VIM) in currents. The awareness and potential...

... of noise. Because the Kalman filter is applied about locally linear trajectories, the feedback of the nonlinearities through the filter has little effect on the overall filtering system. 14 10 2005 03 10 2006 motion control marine engineering offshore installations nonlinear...

... engineering modelling motion control ships The mean displacement and the low frequency motions of a FPSO mostly determine the mooring forces and the watch circle. Considering only waves and current, the mean displacement is caused by the current loads (on the hull, mooring lines and risers) and mean...
