The LIMPET installation
|Decommission date||between 2012 and 2018|
|Wave power facility|
|Type||Oscillating Water Column|
|Nameplate capacity||0.25 MW|
Islay LIMPET (Land Installed Marine Power Energy Transmitter) was developed and operated by Wavegen in cooperation with Queen's University Belfast. Following the construction of a 75 kW prototype in 1991, a 500 kW unit was built in 2000 at Claddach Farm on the Rhinns of Islay on the Scottish island of Islay. The capacity was later downgraded to 250 kW.
Islay LIMPET is a shoreline device using an Oscillating Water Column to drive air in and out of a pressure chamber through a Wells turbine. The chamber of the LIMPET is an inclined concrete tube with its opening below the water level. External wave action cause the water level in the chamber to oscillate. This variation in water level alternately compresses and decompresses trapped air above, which causes air to flow backwards and forwards through a pair of contra-rotating turbines.
A report covering the long term running of the turbine was produced in 2002.
The plant has been decommissioned, and as of 2018 all installations except the concrete construction making up the wave chamber have been removed.
