TL;DR: This work discusses the feasibility of using stationary ship motion measurements for in-site directional wave spectrum estimation, focusing on the particular problems that may arise in the application of adapted estimation methods to this kind of system.

TL;DR: In this article, different options for modeling the second-order hydrodynamic forces and induced motions are discussed using as a case-study the PETROBRAS 52 unit, where the low frequency forces are performed in the frequency domain by means of a commercial Boundary Element Method (BEM) code.

TL;DR: In this article, the second-order hydrodynamics of a semisubmersible offshore wind turbine is investigated by analyzing and proposing a set of different options for estimating the slow-drift motions during its design.

TL;DR: In this paper, the performance of a time domain Rankine panel method applied to the seakeeping problem of two ships in side-by-side configuration is investigated, and the results showed that this technique was indeed able to improve the computational predictions, leading to a closer agreement between the experiments and the numerical results.

TL;DR: In this article, the authors developed a heuristic hydrodynamic model, based on the short-wing theory, for the horizontal current forces on an FPSO (floating production storage and offloading) system.
