Lir National Ocean TF

Lir – the National Ocean Test Facility provides world-class laboratory testing for offshore wind, wave and tidal energy devices. The facilities at Lir include four wave tanks that can replicate real ocean conditions and enable testing of various marine innovations, technologies and structures at different scales. As well as the ocean test infrastructure, Lir also offers a highly experienced team of researchers and operators.

Open Ocean Emulator (25m x 18m x 1m deep): Used for testing a variety of marine structures, such as: wave energy convertors, floating wind platforms, coastal structures, oil and gas platforms. It has a central section with a depth of 2.5m to assist in the testing of mooring lines.

Deep Ocean Basin (35m x 12m x 3m deep): It has a moveable floor plate to allow the water depth to be adjusted, making it suitable for circa. 1/15th scale operational conditions and 1/50th scale survival waves. Equipped with 16 hinged force feedback paddles capable of a peak wave 1.1m in height.

Wave and current flume (28m x 3m x 1m deep): A multi-purpose facility with the capability of running separate and combined unidirectional wave and current tests. It has 8 hinged force feedback paddles and three thrusters for generating current speeds of greater than 1 m/s and it is fitted with a towing carriage that can operate at speeds up to 1.5 m/s.

Electrical laboratory: A dual-bus three phase 400V system consisting of generation, storage, and load elements. It can operate in parallel with the local grid or as an islanded system. Several and varied range of motor options for turbine testing along with a separate fry lab facility for testing of permeable items
