Hexicon is a privately-owned Stockholm based Design and Engineering house developing projects and technology for floating multi-turbine platforms and was founded in 2009. Our patented technology enables the platform to align with the wind direction, giving its turbines free wind and maximizing energy yield. This enables efficient harvesting further offshore in deeper waters in areas with the best wind resources.
Unique benefits Hexicon designs:
By combining double capacity on its platforms, Hexicon’s designs have competitive advantages in park formations resulting in lower costs per installed MW. Hexicon parks require less inter-array cables which saves both CAPEX and installation effort. By sharing the foundation, O&M can be rationalized by access to multiple turbines from a single crew transfer.
Platform assembly is done safely in a drydock providing increased safety during fabrication. The mooring system and export (inter-array) cable is installed prior to platform arriving on site for swift hook-up and electrical connection. One tow operation delivers two turbines which makes the overall installation 50% faster than for single turbine concepts.
Besides economic advantages, Hexicon’s multi-turbine concept reduces environmental impact thanks to the reduced need for inter-array cables which are plowed into the seabed. Geophysical and geotechnical investigation requirements are also reduced. Two turbines on one platform results in more than 10% smaller ocean footprint for small to medium sized farms.
Hexicon has designed several turning solutions as well as specific mooring solutions and aims to constantly expand its IP-portfolio. In 2014 Hexicon was awarded a grant for further R&D projects by the Sweden’s innovation agency, VINNOVA. In 2015 and 2016, basin test at MARIN, Netherlands were successfully completed. In 2016, Hexicon contracted FORCE Technology to measure drag coefficients of the above-water and below-water sections of the hull and turbines to calibrate in the advanced computer model that is used in the engineering of the system.Hexicon’s main project is called Dounreay Trì, its first commercial demonstrator project North of Scotland with construction started 2017 and to be commissioned 2018.
