Oscillating Wave Surge Converter

Technology Description The Nesheim osillating device is composed of an annular shaped floater a floating column a universal joint mechanism and an electrical generator The universal joint mechanism enables relative upwards downwards and pivotal movement between the floater and column The column is provided with an air chamber to provide buoyancy The lower end of the column is connected to an anchor on the seafloor The design of the device enables both vertical and pivotal movement between the floater and the column These features facilitate high efficiency energy capture as the device can capture different forms of motion e g vertical and horizontal The device is attached to a modular buoy system that can be arranged to minimize the mooring line forces and horizontal displacement of the device The performance of the device may be remotely monitored and controlled via a subsea cable

Mooring Configuration The device is either installed between 2 mooring buoys which are coupled to anchors at the sea bottom or between a mooring buoy and an onshore mooring point
Optimum Marine/Riverline Conditions The device can be made in different sizes which should be based on the average wave height at the installation sites
