The responses of offshore structures are significantly affected by steep nonlinear waves, currents and wind, leading to phenomena such as springing and ringing of TLPs, slow drift yaw motion of FPS...
The present paper provides a review of recent research on various nonlinearities that arise in ocean wave interactions with offshore structures. These include nonlinearities associated with the incident waves alone, the response of slender structural members to waves, and the nonlinear diffraction problem...
In the case of fully nonlinear waves, the maximum horizontal wave load on all the piles with the cap can increase by 30% compared with those without the cap, and the maximum horizontal wave load on a single pile is nearly doubled. The horizontal wave load on the cap with the piles can...
waves (e.g., around offshore structures). The equations are derived based on assumptions that the fluid is irrotational, inviscid, and incompressible and that the velocity potential must satisfy Laplace’s equation. Several numerical and computational methods have been developed to solve these ...

To improve both scale and fidelity of numerical water wave simulations to study the evolution of wave fields within offshore engineering, it is of key prac
Radiation and Diffraction of Nonlinear Waves in Three Dimensions The mixed Eulerian-Lagrangian approach is applied to the solution of fully nonlinear wave-body interaction problems in three dimensions. The method is an e... P Ferrant - 《Proc.intl.conf.of the Behaviour of Offshore Structures Boss...
The nonlinear dynamic responses of moored crane vessels to regular wavesare investigated experimentally and theoretically. The main subject ofinterest are nonlinear phenomena like bifurcations and the existence ofmultiple attractors. In the experimental part of the work, a mooredmodel of a crane vessel ...

An offshore wind turbine can be considered as a relatively complex structural system since several environmental factors (e.g. wind and waves) affect its dynamic behavior by generating both an active load and a resistant force to the structure's deformation induced by simultaneous actions. Besides...
