The Lir OOE is 25m * 18 m and nominally 1m in depth. A central trench, equipped with a moveable floor, allows for testing at water depths between 1 and 2.5m. A curved wall of wave generation paddles allows for omnidirectional wave generation which peaks at Hs = 0.16m, Tp = 1.4s and Hmax = 0.32m. The OOE was constructed following the identification, during MARINET1, of the need for more advanced testing infrastructure at early stage Technology Readiness Levels (TRLs).
The OOE has been designed to:
The basin is fitted with a data acquisition system, sensors, 3D motion camera system and a PIV system for flow visualisation.

The Electrical PTO-Lab is a turbine emulator to reproduce the mechanical output of an ocean energy device/wind turbine
It consists of a HIL (Hardware in the Loop) test bench for grid connection of wind turbines and ocean energy converters, focused on testing electrical components
(electrical generators and/or power converters). This test bench simulates the power production of a device with a rotary movement and it can be divided into three key elements: Device Emulator, Electrical Generator and Power Converter.
Services currently offered by the infrastructure:

The Dutch Marine Energy Centre provides excellent opportunities for tidal energy converter testing at intermediate scale. The onshore facility Den Oever is located in two ducts of the Afsluitdijk, in an existing sluice that discharges water from the IJsselmeer to the Wadden Sea. The main function of the sluices always remains dominant; test equipment must be placed in such a way that it can be easily removed or lifted. Basic infrastructure is available, including E&I grid, ADCP, and reaction construction (foundation). The site is typically used for 1:1 scaled river turbine applications, and for 1:4 scaled tidal stream solutions.
The Dutch Marine Energy Centre provides excellent opportunities for tidal energy converter testing at intermediate scale. The location at Marsdiep is sheltered and well-accessible via the NIOZ harbour, and the water column has a depth of over 20 metres. The Marsdiep location can be equipped with a floating platform. DMEC has the permit to use a near shore location for testing tidal turbines. The location is used by a consortium which developed the floating BlueTEC platform. Under conditions to be set, the platform can be made available for testing. But at the Marsdiep Berth other platforms can be tested as well. Anchor points, umbilical, grid connection can be made available if needed.
The PLOCAN Marine Test Site is located on the East coast of Gran Canaria Island (Spain, www.plocan.eu). The Canary Islands are located in the Atlantic Ocean, south-west of Spain and Northwest of Africa. The marine test site includes an area of about 23 km2 with a wide range of water depth from shoreline to 600 m. This Marine Test Site is available to projects focused on testing and demonstrating of all kinds of marine devices but mainly marine renewable energy converters. The final testing decision would be conditioned to the appropriateness, opportunity and availability of the facilities.
The electrical and communication infrastructure (REDSUB) is composed of two medium voltage cables (13.2kV) with a capacity of 5MW, each one, within the range of ±1% of 50Hz. The infrastructure will be mostly underwater, comprising hybrid cabling, with copper cables for the transmission of electrical power and fibre optics for data transmission, including a short terrestrial section to connect to the electrical substation on land. The onshore infrastructure will go from the manhole up to the electrical substation (66kV), where the electricity is raised up for its deliver to the national transmission grid. The onshore infrastructure will be composed by an underground medium voltage cable with a capacity of 15MW, by a power transformer station (13.2kV to 66kV) and all electrical protections required. This part will only be available after the Summer of 2017.

EMEC’s HIL PTO testing rig will provide a sequence of speeds and loads to a power take off by an actuation device, simulating waves on dry land for the purpose of accelerated testing of power take off systems for wave energy convertors (WEC).
The test rig can also be used to adjust the PTO and the controller parameters to validate assumptions for performance optimisation and survivability modes. Furthermore, it can be used for fatigue, loads or efficiency testing of a specific sub-system of the WEC. The rig will have a stroke length of 3.5m, a rated velocity of 2.7m/s and a maximum rack force of 207kN.
The rig will primarily be used for simulating wave loading on PTO systems for WEC. However, EMEC are open to suggestions for other projects that could utilise the testing rig facility.

Biscay Marine Energy Platform (BiMEP) is an infrastructure for testing marine energy converters, located just off the coast of Armintza, northern Spain. With a grid connection capacity of 20 MW, purpose built substation and offices, the platform offers technology developers the opportunity to demonstrate their latest devices in test-friendly wave conditions. Along with a sister installation at Mutriku (Mutriku Wave Power Plant) BiMEP is able to provide a wide range of services in real sea conditions.
In addition, a consortium made up of BiMEP and IH Cantabria has been tasked with developing a scientific and technological project called TRL+. The purpose of TRL+ is to offer innovative tailored solutions for the development of marine technologies from concept through to field testing.

The French research sea test site (SEM-REV) is part of the experimental facilities of Ecole Centrale Nantes to develop marine based energy generation products. The 1km2 site is located 10 nautical miles West-South-West of Le Croisic’s cape on France’s western Atlantic coastline with water depths ranging from 32-36m.
The area has a restricted access for navigation and has all permitting to install Ocean Energy devices to be tested. Offshore wind energy and wave energy converters can be tested, as well as all sub-components and installation and maintenance operations. The site is connected to the grid and has the possibility to connect three devices.

This plant consists of a hollow reinforced concrete structure – pneumatic chamber – above the water free surface that communicates with the sea and the incident waves by a submerged opening (1+3) in its front wall, and with the atmosphere by a fibre duct with an air turbine (2+4).
The incident waves cause vertical oscillation of the water column inside the chamber, which in turn causes alternate air flow to and from the atmosphere, driving the turbine and the generator attached to it. The electricity is fed into the local grid of EDA (Regional Utility) at the Cachorro grid connection point. An important factor in designing this kind of plants is the dimensions of the pneumatic chamber, in order to provide resonance with the incident sea state.
