Benefits of technology

[0014]In some embodiments, the one or more air ducts may have an opening on the upwave side. According to this feature, any noise created by the turbine and the moving water column and air column is directed towards the upwave side and away from e.g. a port and residencies located on the coast. Optionally, the one or more air ducts may also comprise a valve for selectively closing off the air duct. The OWC may thus be protected during high waves or storms.
[0015]In some embodiments, the lid may comprise a plurality of moulded concrete sections. By dividing the lid in prefabricated sections, the overall installation, and particular

first embodiment

[0027]FIG. 1a illustrates a cross-sectional view of a caisson breakwater module 100. The breakwater module has an upwave side 110, from which the waves strike upon the module and a downwave side 120, where the sea will generally be calmer. On the downwave side 120, e.g. a port or harbour may be located. The breakwater module may thus form a protective barrier for the port and any boats present in the port.

[0028]Reference sign 12 indicates the water level, whereas reference sign 11 indicates the height of the waves. The module comprises a base 20 installed on sea bed 5. A lid 50 may be placed on top of the base to form the breakwater module 100.

[0029]An Oscillating Water Column (OWC) is provided in the breakwater module. The OWC may comprise a substantially horizontal water inlet 25. Water enters through the inlet, and due to the sea's wave action, a water column will oscillate in water oscillation chamber 21. The oscillating water column causes an oscillating air flow through air ch...

fourth embodiment

[0046]FIGS. 4a-4d illustrate various views of a module according to a Similar components have once again been indicated with the same reference signs. From FIG. 4a, the sealed chamber 57, turbine chamber 51, water inlet 25, and wind turbine 70 are readily recognizable. Contrary to previously shown embodiments, the rear lid section behind the turbine chamber is not a substantially flat surface on top of base 20. Instead, in this embodiment, a covered space 97 underneath the deck is provided. This space may be substantially closed or open towards the sea. The covered space 97 may be divided into separate chambers 97a and 97b. These chambers may potentially serve many different purposes.

[0047]In the particular embodiment shown, the chambers are used for housing a desalination and water storage system. Desalination machinery 99 may be housed in chamber 97a. Fresh water resulting from the desalination process may be stored in chamber 97b. This fresh water may be used locally, e.g. in a ...

Abstract

A caisson breakwater module having an upwave and a downwave side and incorporating an oscillating water column, the caisson breakwater comprising a base installed on the sea bed and a lid adapted to be positioned on top of said base, the base defining a water inlet on the upwave side and further defining a water oscillation chamber, and the lid defining a breakwater section on the upwave side, a turbine chamber, one or more air ducts connected with said turbine chamber and an additional substantially sealed chamber. The invention further relates to a breakwater comprising a plurality of such modules and a lid suitable for use in such modules.

Description

[0001]The present invention relates to a caisson breakwater, and more particularly relates to a caisson breakwater module incorporating an Oscillating Water Column (OWC). The present invention further relates to a breakwater structure comprising a plurality of such modules and to a lid particularly suitable for such a module.BACKGROUND ART[0002]Breakwater structures are structures that generally serve to reduce the erosion of a coast by reducing the intensity of wave actions. They may be built at or near the coast and may be used as a protective border of a harbour or port. It is also known to use them offshore (i.e. further away from the coast), with the same scope of protecting the coast e.g. a beach.[0003]Breakwater structures may be built with one end linked to the coast or completely separated from the coast. It is known to provide floating breakwater structures or to construct them on a foundation on the sea bed. Breakwaters of different types are known: on the one hand, rubbl...
