As part of the OPERA H2020 project, the Mutriku Wave Power Plant is being used as a real condition laboratory for the experiment of innovative technologies. The plant is situated in the Basque Country and has been operating since 2011.
Boundary Element Methods are extensively used to model hydrodynamic
forces in offshore devices like ships, offshore wind platforms and wave
energy converters. These solvers use device geometry mesh to get some
hydrodynamics coefficients as radiation damping, added mass, wave
diffraction force, and wave excitation force. All these data is saved in
file formats incompatible between them. These may avoid to use the
coefficients between programs.
BEMRosetta allows to load the hydrodynamic coefficients from a format
saving it in another. In addition it allows to compare the results
obtained between programs, the results between similar geometries and
the same geometry with different discretization levels.
In addition, BEMRosetta allows to view and visually compare the meshes from different programs.
DTOcean, which stands for Optimal Design Tools for Ocean Energy Arrays, aims at at accelerating the industrial development of ocean energy power generation knowledge, and providing design tools for deploying the first generation of wave and tidal energy converter arrays. It gathers 18 partners from 11 countries (Ireland, Spain, United Kingdom, Germany, Portugal, France, Norway, Denmark, Sweden, Belgium and United States of America) under the coordination of the University of Edinburgh.
DTOcean work planning has been implemented as five content-orientated Work Packages (Hydrodynamics, Electrical Sub-systems, Moorings & Foundations, Installation and Operations & Maintenance) guided by two defining work packages (Scenarios and Management & Coordination) which set the underpinning scope in relation to a range of array sizes and hydrodynamic layouts. The outputs, feedbacks and interactions within these culminate in the Integration Work Package where the design tools are actually developed.
The newly released, open-source, integrated DTOcean v1.0 software package can be downloaded here.
OPERA is a European wave energy project which aims to collect long-term open-sea operating data from offshore and shore installed devices, delivery results for reducing structural costs and greatly increase power production, reduce technology-related uncertainties and advance standards for reducing business risk.
