Seabased Prepares to Launch Thirty WECs Off Sweden

In early July 2014 Seabased launched the first ten WECs outside Smögen/Kungshamn. The operation took two days and the generators are located in the southeastern part of the park.

In the next few months, a further thirty units is to be launched and anchored with buoys. The units will then be connected to a substation and the land cable.

Seabased’s wave power technology utilizes the water motion in waves to directly drive the wave enery converter (WEC). Seabased’s wave energy technology is based on WECs with linear generators, deployed on the seabed. The generating unit placed on the seabed is connected to a buoy on the surface via a line, which captures the energy in the motion of the waves, enabling the WEC to generate electricity. The WECs are connected to marine substations, from where an alternating current can be transmitted directly to the onshore grid.

Deployment of the units containing linear generators on the seabed protects the units from extreme conditions that may occur at the surface of the sea and help minimize required maintenance. Combined with a mechanically simple (very few moving parts) and robust generator technology, this yields an efficient energy conversion system.
