TL;DR: In this paper, the structural responses of offshore wind turbines are simulated with an attached damper (Tuned Liquid Column Damper) for controlling the vibrations induced within the structure, and a fatigue analysis is carried out and the implementation of TLCDs is seen to enhance the fatigue life of the structure.
TL;DR: In this paper, the authors describe the validation of an SPH-based technique for wave loading on coastal structures, which is used for the scope of wave impact on vertical structures and storm return walls.
TL;DR: In this article, OpenFOAM is applied to non-linear wave interactions with offshore structures for ranges of wave conditions, and the numerical results for wave interaction with a vertical surface piercing cylinder have been compared with physical experiments performed at Danish Hydraulic Institute (DHI).
TL;DR: In this article, the authors discuss the potential-flow forces of the second order in the amplitude of ambient velocity fluctuations and the major role played by these forces in wave loading on offshore structures.
Abstract: This article is aimed at relating a certain substantial body of established material concerning wave loading on offshore structures to fundamental principles of mechanics of solids and of fluids and to important results by G. I. Taylor (1928a, b). The object is to make some key parts within a rather specialised field accessible to the general fluid-mechanics reader.The article is concerned primarily to develop the ideas which validate a separation of hydrodynamic loadings into vortex-flow forces and potential-flow forces; and to clarify, as Taylor (1928b) first did, the major role played by components of the potential-flow forces which are of the second order in the amplitude of ambient velocity fluctuations. Recent methods for calculating these forces have proved increasingly important for modes of motion of structures (such as tension-leg platforms) of very low natural frequency.
TL;DR: In this article, a comprehensive study on the dynamic behavior of offshore wind turbine (OWT) structure supported on monopile foundation in clay is performed using a beam on nonlinear Winkler foundation model.
