Pelamis Wave Energy Converter
The pelamis device consists of a series of semi submerged cylindrical sections linked by hinged joints. The wave induced relative motion of these sections is resisted by hydraulic rams which pump high pressure oil 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.
Ocean Power Delivery Ltd, the company, which develops this novel offshore wave energy converter has been awarded a contract to install a pair of 375kW prototype devices off Islay, Scotland, under the 1999 Scottish Renewables Obligation (SRO3). The devices are scheduled to be installed early in 2002 and will generate over 2.5 million kWh's of electricity per year, enough to provide power for 150-200 homes. The aim of these prototypes is to prove the technology and provide a facility for testing and developing further aspects of the device.
