TECHNOLOGY
The project was started in 2009 and enabled ChapDrive to develop a conceptual design of a 5 MW wind turbine with hydraulic transmission based on the ChapDrive Ground Solution for off-shore purposes. Furthermore the project aimed at developing and verifying the ChapDrive simulation tools and dynamic models such as ChapDrive Wind turbine datalogger, ChapDrive AEP & CoE model, ChapDrive Wind Turbine Simulator and ChapDrive Mechanical Design Tool. Verification of the simulation tools and dynamic models was done based on results from the 225 kW and 900 kW wind turbines.
The ChapDrive simulation tools and dynamic models showed good agreement with measure results and that a 5 MW off shore wind turbine with ChapDrive hydraulic transmission is feasible with a top weight of less than 200 ton. Cost of energy analysis was done based on capital cost, operation and maintenance cost, efficiency and annual energy production. When compared to traditional wind turbine drivetrain solutions, the result showed a potential of 20 % reduction in Cost of Energy for the ChapDrive solution.
The project was executed in an industrial research and development agreement with Statoil and Innovation Norway. The agreement secured funding of NOK 52 million (EUR 6 million) including soft funding from Innovation Norway of NOK 18 million (EUR 2.1 million).
The project was completed successfully in December 2010.
