GL Garrad Hassan has launched an ambitious project to bring fresh thinking to the design of offshore wind turbines. Project FORCE (turbine optimization FOr Reduced Cost of Energy) will build on GL Garrad Hassan’s expertise in turbine design, control system engineering, and structural modeling. The project will systematically consider new technologies that can be applied to offshore wind turbines and their support structures with the target of reducing the cost of energy from offshore wind farms.
Adopting an open-minded approach, Project FORCE will focus GL Garrad Hassan engineering expertise on the design of low cost offshore wind turbines in the 7-10MW range. Technologies to be considered include rotor design and innovative control systems which reduce structural loads at the same time as regulating turbine power.
The UK Government’s Offshore Wind Cost Reduction Task Force showed that offshore wind can achieve a levelized cost of energy of £100/MWh by 2020 and The Crown Estate’s Cost Reduction Pathways project identified ‘Technology Acceleration’ as one route to achieving significant cost reductions.
GL Garrad Hassan’s Project FORCE addresses the challenge of cost reduction, focusing in particular on the use of new and innovative technology in offshore applications.
In an integrated design and cost analysis environment, Project FORCE will center on advanced control and rotor technologies. Possible technologies include:
– Advanced control systems including high order individual pitch control, multivariable and Lidar assisted solutions;
– High speed, structurally flexible, downwind rotor blades;
– Fully integrated wind turbine, controller and support structure design;
– Use of topology optimization software to further improve wind turbine main structural components.
The results of the project will be made available to the industry later this year.
GL Garrad Hassan has been at the forefront of wind turbine design for nearly three decades and is able to draw on an integrated system approach to wind turbine design. Its experts have been involved with all major wind turbine manufacturers for onshore and offshore wind turbines. This heritage, combined with a flair for innovative engineering, is the ideal starting point for the development of creative solutions to reduce the cost of energy from offshore wind turbines. Results of the project are expected in late 2013.
