Ocean Wave Basin, COAST Lab, Plymouth

Location: Plymouth University, Coastal, Ocean and Sediment Transport Laboratory (COAST)

Website: www.plymouth.ac.uk/coast

Main Feature :  35 m long x 15.5 m wide x 3 m deep, operable at different depths and incorporating 2.0 m hinge depth wavemakers and recirculating current both inline and across the waves

The Ocean Basin is a unique facility that allows waves and currents to be generated at any relative orientation and can be run at different water depths. This basin can be used to create unidirectional and directional wave fields, regular waves, wave spectra and currents in three dimensions. Future developments of the facility include the provision of wind generation in two directions.

Coastal Basin, COAST Lab, Plymouth

Location: Plymouth University, Coastal, Ocean and Sediment Transport Laboratory (COAST)

Website: www.plymouth.ac.uk/coast

Main Feature: 15 m long x 10 m wide x 0.5m deep, incorporating moveable modular piston wavemakers and recirculating current

The Coastal Basin allows sediment transport, coastal processes and coastal engineering solutions to be studied in a controlled environment. Optimisation of coastal structures is a key element of the engineering design process. The Coastal Basin provides the ability to examine structural response under combined wave and current forcing.

Sediment Wave Plume, COAST Lab, Plymouth

Location: Plymouth University, Coastal, Ocean and Sediment Transport Laboratory (COAST)

Website: www.plymouth.ac.uk/coast

Main Feature: 35 m long x 0.6 m wide x 0.8 m deep

The Sediment Wave Flume allows the interaction of waves, current and sediment dynamics to be studied. The inclusion of current circulation in the facility allows tidal energy as well as wave energy technology to be investigated. The novel current circulation technology enables a smooth current to be modelled without disturbing the wave signal, this enables the controlled study of wave-current interaction and wave-current-device interaction.

DMaC (Dynamic Marine Component test), Falmouth

Location: A&P Falmouth, Building 420, Falmouth, TR11 4NR

Website: DMaC website

Main Feature: To be able to replicate the motion characteristics and loadings experienced by MEC components, or sub component, the test rig will provide a one degree linear motion that can be used to replicate a pulling and pushing force representative of dynamic loadings, pre-loadings, etc. (termed the Z actuator in the tailstock position), and a headstock with three degrees of freedom (namely pitch, roll and yaw) representative of x- and y-bending or torsion. The DMaC test rig will have a unique feature that is relevant to the testing of components for marine renewable energy devices, allowing to immerse components in fresh water and the dynamic testing in a wet environment. These features will allow a dynamic testing of components in large scale under controlled environment applying realistic motion characteristics.
