Two French companies have come together to launch a floating substation concept for offshore windfarms.
Floating foundation company Ideol and Atlantique Offshore Energy (AOE), Chantiers de l’Atlantique’s business unit focusing on offshore projects such as substations for the bottom-fixed offshore wind market, held a one-day technical seminar in Paris on 4 June 2019 and unveiled details of the floating substation, which they say is ‘market-ready.’
The French companies have been working with ABB on the concept, which is suitable for use in water depths of in excess of 40 m.
Based on Ideol’s patented shallow-draft Damping Pool concept and on AOE’s SeeOs offshore substation, the floating offshore substation is designed to operate in extreme environments and is of modular design.
The topside for the floating substation would be installed on the floater at a quayside. Testing and pre-commissioning would also take place at the quayside. This eliminates the need for heavy-lift operations offshore, which would generate significant cost savings.
The companies said the ‘universal and modular’ floating substation is ready to be proposed for upcoming floating commercial tenders in France and elsewhere.
Ideol chief sales and marketing officer Bruno Geschier said the concept had been well received by developers and transmission system operators.
