Floating Power Plant develops a multi-use platform combining wind and wave technology. The company is entering the commercialisation stage, based on over 8 years of R&D, testing and business development. FPP has successfully operated a half scale offshore prototype for over 2 years – making FPP the only company in the world that have successfully provided power to the grid from wave and wind at the same time. The company is backed by 156 private shareholders and leading industrial development partners.

BESMAR similarly has extensive experience in the aquaculture sector. The advantages of this multiple use of space (MUS) include more efficient use of scarce licenced space and possible complementarities, including, among others, using the floating structures to protect part of the “cages” from the damage of strong currents and shared security and monitoring systems. The deployment location planned is the South-East coast of Gran Canaria. The concept was identified and examined previously in the EU TROPOS project.
Wave Dragon, Seaweed Energy Solutions (SES) and BELLONA are working together on a combined wave and aquaculture project. This concept envisages an array of wave energy converters (WEC) of a design created by the Wave Dragon, combined with a seaweed farm. The seaweed farm will benefit from calmer water behind the devices, enabling them to be located in areas which would not normally be viable. During periods of rough seas, electricity from the WECs can be used to winch the seaweed farms lower into the water, protecting them from any ill-effects. Electricity from the WECs will be exported to the grid. The combination will benefit from an easier licencing process due to the multiple use of space, and there are expected to be synergies for installation, inspection and maintenance operations. The expected location of the pilot deployment is off the Welsh coast.
This combination is a mixed use platform (MUP) designed by J.J. Campbell & Associates, consisting of a large V-shaped concrete structure incorporating Oscillating Water Column (OWC) wave energy converters, with a wind turbine mounted on the platform via a steel superstructure.
The concrete construction is modular allowing easier fabrication and assembly. Other advantages of the concrete construction include the cost-effectiveness of concrete as opposed to an entirely steel construction, ease of maintenance and the proven technique of slip-form concrete construction.
By combining wave and wind technology in the same platform, the economic viability of the technology will be increased. The aggregation of wind and wave energy converting technologies reduces the variability of the power generated by the platform as a whole with respect to time. It will also be able to make maximum use of the resources available at any particular location, and due to the floating aspect, will be deployable in water depths previously beyond the limits of current fixed offshore wind technology. Planned deployment location for the pilot is off the west coast of Ireland.
