Optimization theory is applied to a coastal engineering problem that is the design of a port.This approach was applied to the redesign of La Turballe Port in order to increase the exploitable surface area and simultaneously reduce the occurrence of long w
The collision of ships poses a great threat to the piers in navigable waters.The kinetic energy of the moving ship can be consumed not only with the structural deformation,but also with tensile force from the proposed Floating Two-stage Buffer Collision-P
Fully nonlinear water entry of a cone into waves with gravity effect has been analyzed based on a three-dimensional(3D) higher-order boundary method (HOBEM).The total velocity potential at the initial time is divided into the incident and scattering compo
The wave-induced fluid resonance between twin side-by-side rectangular barges coupled with the roll motion of the twin barges is investigated by both numerical simulation and physical model test.A 2D numerical wave flume,based on an open source computatio
Mooring system failure can lead to largely different dynamic response of floating structures when compared to the response under the condition of intact mooring system.For a semi-submersible platform with taut mooring system under extreme environmental co
An improved three-dimensional (3D) time-domain couple model is established in this paper to simulate the bidirectional vortex-induced vibration (VIV) of a deepwater steep wave riser (SWR) subjected to oblique currents.In this model,the nonlinear motion eq
Flow-induced vibration (FIV) of a group of long,flexible cylinders involves a complex interaction between fluid and structures.Although a substantial number of studies have been devoted to assessing FIV response behaviours,fatigue damage features of stagg
Edinburgh Duck wave energy converter (ED WEC) has excellent energy extraction performance and shows a great potential to integrate with other marine structures.This paper aims to investigate its wave energy extraction performance as a WEC and wave attenua
Flow-induced vibration (FIV) of four separately mounted cantilever cylinders are experimentally investigated in a water flume.The four cylinders with top ends screwed vertically into a turntable platform are subjected to uniform flows with Reynolds number
The comb-type breakwater (CTB) has been proposed and investigated in recent years due to its advantages in terms of deep-water adaptability,material saving and water exchanges.All existing empirical formulae for CTBs have been so far restricted to the wat
