WAVE BASINS
Lir NOTF consists of state of the art wave tanks and electrical rigs that allow for scaled testing in a controlled environment.
The state of the art facilities comprise a 2,600 m^2 tank hall which houses 4 different wave tanks. These include a new deep ocean wave basin (circa 1:15 scale testing) and capable of producing waves of up to 1.2 metres high, an ocean wave basin (circa 1:50 scale testing), a wave and current flume with coastal/tidal testing capabilities (circa 1:50 scale testing) and a wave demonstration flume.
| Deep Ocean Basin |
| 35 m x 12 m x 3 m deep |
| It has a movable floor plate to allow the water depth be adjusted, making it suitable for circa. 1/15 scale operational conditions and 1/50 scale survival waves. Equipped with 16 hinged force feedback paddles capable of a peak wave generation condition of Hs = 0.6 m, Tp = 2.7 s and Hmax = 1.1 m. |
| Ocean Basin |
| 25 m x 18 m x 1 m deep |
| Used for testing a variety of marine structures (wave energy convertors, floating wind platforms, coastal structures, oil & gas platforms). It has capacity for adding a 2.5 m deep section and it can produce real and simulated sea states. The wave generation peaks at Hs = 0.16 m, Tp = 1.4 s and Hmax = 0.32 m. |
| Wave & Current Flume |
| 28 m x 3 m x 1 m 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 with adjustable height positioning and three thrusters for generating current speeds of greater than 1 m/s. The wave generation peaks at Hs = 0.16 m, Tp = 1.5 s and Hmax = 0.35 m. It is fitted with a towing carriage that can operate at speeds up to 1.5 m/s. |
