Abstract

This report addresses a number of key issues in the physical and numerical testing of marine renewable energy systems, including wave energy devices, current turbines, and offshore wind turbines. The report starts with an overview of the types of devices considered, and introduces some key studies in marine renewable energy research. The development of new ITTC guidelines for testing these devices is placed in the context of guidelines developed or under development by other international bodies as well as via research projects. Sites developed around the world for full-scale testing of Marine Renewable Energy Devices are discussed. Some particular challenges are introduced in the experimental and numerical modelling and testing of these devices, including the simulation of Power-Take-Off systems (PTOs) for physical models of all devices, approaches for numerical modelling of devices, and the correct modelling of wind load on offshore wind turbines. Finally issues related to the uncertainty in performance prediction from test results are discussed. Definition of the stages of a device test program Technology Readiness Level (TRL) definition
  • Summary of testing requirements / challenges for device type (ocean v tidal current, rotating v non-rotating, shallow v deep deployment, rigid mounting v flexible mooring) and device development stage;
  • Coupling between model scale, choice of facility, device type, and experiment stage.
  • Identification of common error sources associated with small to field-scale testing with guidelines on impact on test success, interpretation of test results and how to quantify and report measurement error.
