Looking for a simplified approach for the propagation of systematic uncertainty in the motion response of a floater

This new research considers the 3 main motions of moored floater (surge, heave and pitch) in head waves it explores ways to estimate systematic uncertainties on RAOs, 2 other metrics for these signals. Based linear hydrostatics potential flow theory, simple relations can be found that bind characteristics a floater. These are transformed using algebra express how uncertainty bias tested system propagated motion responses Thanks this approach, variations mooring stiffness, position centre mass, radia gyration represented through formulations allow very effectively assess their impact RAOs metrics. approach is verified by comparing simulation test results semisubmersible MARINET2 floating wind round robin campaign approximations deduced from theoretical relations.
