Oscillating Device

The oscillating device utilises the movement of ocean waves to create useful energy e.g. electricity. The device is equipped with air pumps that are activated by pivotal and vertical movement between the floater, column and sea anchor. The air pumps are coupled to a turbine that drives other equipment such as an electrical generator. The devices can be arranged in groups to deliver power to a single electrical generator. The system includes energy storage equipment enabling scheduled use of the energy. 

Isometric view of the oscillating device
		The device include an annual shaped floater, coupled to a floating column by means of an universial joint mechanism. The lower end of the column is connected to a sea anchor.
		The device is able to capture energy from different forms of motion i.e. vertical, pivotal, horizontal backwards and forwards (to-and-fro) movement. Horizontal to-and-fro movement will occur when the device is moored to a buoy, or other device which could act as a spring.

 

Group of wave energy devices
		The device can be arranged in groups to deliver power to a single electrical generator.
		The system include energy storage equipment that enable scheduled use of the energy. The performance of the device may be remotely monitored and controlled via a subsea cable.

The device is based on patent No NO311371.


Key benefits:

	High utilisation of the energy in ocean waves as the device is able to utilize the energy in different forms of motion
	Low fabrication costs
	Works in any wave direction
	Easy to deploy and operate
	Components easily accessed for inspection and repairs
