Aquamarine Power Internal Guidance


Historic Information

Aquamarine Power Ltd (APL) was a wave energy company responsible for developing a wave energy converter called Oyster. The Oyster system consisted of a Wave Energy Converter (WEC) located in shallow water close to the shore, with a bottom-hinged flap which oscillated due to wave action.

APL deployed a full-scale 315 kW Oyster 1 system at the European Marine Energy Centre (EMEC) in August 2009, followed by a second generation machine rated at 800kW, Oyster 800, in August 2011. Oyster 800 utilised double acting pistons on each side of the WEC which pumped water through a high pressure pipeline back to shore, where high pressure water drove a Pelton wheel turbine connected to an electrical generator. The flow from the Pelton wheel discharged to a header tank and returned to the WEC via a low pressure return pipeline.

APL ceased trading in November 2015, and the intellectual property was acquired by Wave Energy Scotland (WES), who propose to share relevant documents and information acquired with developers in the WES programme and the wider sector.

The documents included here capture internally produced guidance and learning records which were produced by Aquamarine Power in order to be applied to future WEC designs, and any ongoing engineering design work required on Oyster 800. They are now being shared by WES to support other WEC developers who may be facing similar issues and challenges.

Further documents will continue to be added to this collection over time.
