These datasets contain the measurements collected on the same model of wave energy converter across four facilities during the Marinet2 Round Robin Testing Program. The involved infrastructures are University College Cork, University of Plymouth, University of Edinburgh and Centrale Nantes. The datasets consist of :

  • the PTO characterisation tests (only for Centrale Nantes)

  • the decay tests

  • the regular and irregular wave calibration tests without model

  • the model tests in regular and irregular waves

The data is delivered in a compressed file which includes :

  • An excel file with the description of test conditions for each test, the channel lists and the list of exported variables for each test.  

  • A pdf file describing the model, moorings and wave gauges locations in the basin.

  • Sensors datasheets and calibration documents

  • A NetCDF file for each test containing :

    • Array variables corresponding to the measurement channels. These array variables are named with the measurement channel names and have a variable attribute corresponding to their physical unit. For wave gauges, additional variable attributes are set for X and Y location in the wave tank.

    • Global attributes to describe the wave conditions, the infrastructure references, the basin dimensions… They are listed in the excel file.

Acknowledgements These datasets collection was funded by the European Union’s Horizon 2020 research and innovation programme under Grant Agreement Number 731084, Project MaRINET2 (Marine Renewable Infrastructure Network for Enhancing Technologies 2). They are the result of the work of many individuals of ECN, IHC, UCC, UoE and UoP who may have not been named as authors, but whose contributions were important. The authors would like to thank them all. UCC is particularly obliged to TomWalsh and Christian van den Bosch for their contributions. ECN is grateful to Virginie Baudry and Aurelien Babarit for their contributions to the numerical simulation of the raft and to Sylvain Bourdier for the definition of the test program. UoP would like to acknowledge the contribution of Kieran Monk and Federica Buriani from COAST. UoE would like to thank Martyn Lennon for his contribution to the execution of the FloWave test programme.
