Wave Energy Technology Approaches Commercialization: Pelamis
Pelamis Wave Power Ltd which is a manufacturer of a unique system to generate renewable electricity from ocean waves has recently announced the sale of one if its next generation wave power generators. According to the company they have recieved an order from E.on, one of the UK’s leading renewable generators, for the next generation of Pelamis Wave Energy Converter, known as the P-2.

The machine will be built at PWP’s new Leith Docks facility Edinburgh and put through its paces at the European Marine Energy Centre (EMEC) in Orkney. The new machine will be 180m long and includes a range of enhanced design features to improve performance and ease of manufacture. This will be the first time a major utility has ordered a wave energy converter for installation in the UK and the first time the P-2 machine will be tested anywhere in the world.
The Pelamis Wave Energy Converter is a semi-submerged, articulated structure composed of cylindrical sections linked by hinged joints. The wave-induced motion of these joints is resisted by hydraulic rams, which pump high-pressure fluid through hydraulic motors via smoothing accumulators. The hydraulic motors drive electrical generators to produce electricity. Power from all the joints is fed down a single umbilical cable to a junction on the sea bed. Several devices can be connected together and linked to shore through a single seabed cable.
