... on the system natural periods. We first apply Irvine’s method to model both the shared line and the two-segment single lines. The response surface method is proposed to replace iterations of the catenary equations of the single lines, and a realistic single line design is presented for OC3 Hywind. Then, system...

... laptop computer. The computational time involved in the evaluation of the system safety margins for a large number of realizations of the basic random variables may therefore be prohibitive. This is a typical problem where the response surface method can be applied, substituting Eq. (20) by a suitable...

... to obtain, Monte Carlo simulation with variance reduction techniques can be used instead. However, when it comes to large and complex structural system, this approach is much more prohibitive than the design sensitivity analysis. To alleviate this dilemma, the response surface method (RSM) has been proposed...
