Breakwaters are characteristic maritime works and provide basic infrastructure for artificial sea land areas such as ports [...]

In this paper, a yacht project in Tingjiang Town, Mawei, Fujian, is suggested as an example of barge type breakwater made out scrap barges. The physical modelling two-dimensional flume wave test was carried on barge-type breakwater, focusing the dissipation and anchor chain forces under two different mooring methods, “crossed tilt” “front rear direct pull” mooring, with no change size breakwate...

A set of tools that is being developed for the automated inspection of rubble-mound breakwaters, as well as its application to the survey of Sines' west breakwater armour layer, are described. The results from the IRIS surveys are compared to those of the surveys carried out by the Portuguese Hydrographic Institute and first assessment of the structure evolution between 2000 and 2003 is made.

To share the construction and maintenance cost, an asymmetric oscillating water column (OWC) device integrated with a pile-fixed box-typed offshore breakwater is considered experimentally numerically. A fully nonlinear numerical wave tank established validated open source solver OpenFOAM. The effects of width draft rear box, incident height on energy conversion efficiency, reflection transmissi...

This paper presents the results from a numerical simulation study to investigate wave trapping by series of trapezoidal porous submerged breakwaters near vertical breakwater, as well seabed response around breakwater. An integrated model, based on volume-averaged Reynolds-averaged Navier–Stokes (VARANS) equations is developed simulate flow field, while dynamic Biot’s are used for simulating wav...

A plate-wave energy converter (pWEC) moored in front of a floating stationary breakwater is considered. The pWEC composed submerged flexible plate with piezoelectric layers bonded to both faces it. Hence the elastic motion excited by water waves can be transformed into useful electricity due effect. To evaluate performance breakwater-attached terms wave power absorption and attenuation, hydroel...

Breakwaters are the important and the costly ones of the marine structures. Composite breakwater is one of the common types in the world. Because of the sensitivity of composite breakwaters to environmental conditions, also construction costs, difficulty of repair and maintenance and importance of equipments on and behind the breakwater, design of composite breakwater must be very accurate.
