We installed our first full-scale 315kW Oyster wave energy
device at the European Marine Energy Centre's test site at Billia
Croo, near Stromness in Orkney in the summer of 2009.
Scotland's First Minister Alex Salmond MSP officially switched on
Oyster 1 on 20 November 2009.
Oyster 1 successfully demonstrated the feasibility of using wave
energy to pump high pressure water to an onshore hydro-electric
turbine to create electricity.
Oyster 1 delivered over 6000 offshore operating hours, survived
two winters at sea and performed in line with predictions made from
our design model. Oyster 1 also achieved continuous 24 hour
generation - a major achievement for a first full-scale
Development of Oyster 1
We conceived, engineered and installed our first Oyster wave
energy project over the period from 2005 to 2009. Aquamarine
Power completed the Oyster 1 project in-house with support from a
number of engineering, fabrication and construction
Two year design life
The Oyster 1 device was built with a two year design life.
In spring 2011, we took advantage of calm weather conditions to
remove Oyster 1's buoyant flap and tow it from its berth to a
sheltered seabed site at Lyness, around ten miles south-east of
Oyster 1 learnings
Oyster 1 generated significant operational experience, learning
and data for use in Aquamarine Power's future Oyster
projects. We are currently inspecting the Oyster 1 flap to
find out how the device's tubes, bearings, seals and other
components have fared after two winters at sea. We will feed
learnings from these inspections and from performance data gathered
from Oyster 1 into the development and construction of subsequent
Oyster design iterations.

Orkney Islands Council was delighted to see the successful installation of the first Oyster wave energy device in 2009. The Council fully supports the work Aquamarine Power is doing to optimise growth of the wave energy industry in Orkney.Stephen Hagan, Convener

Leask Marine was contracted to provide commercial diving services on Aquamarine Power’s Oyster 1 project. It has been great to be involved in such an important project from the beginning and we are pleased to see Aquamarine Power choosing to work with local contractors such as ourselves.
