Offshore Wind
References
Smulders and its consortium partner EQUANS are building the offshore substation for the Saint-Brieuc offshore wind farm. The substation will set sail to the wind farm in June 2022.
About the wind farm
The Saint-Brieuc offshore wind farm, located 16.3 km off the French coast, is the first large scale offshore wind farm in Brittany and one of the first in France to obtain all the necessary government permits for its construction and operation. The wind farm covers a total area of 75 km², will have a total capacity of 496 MW and will produce 1,820 GWh annually, equivalent to the annual electricity consumption of 835,000 inhabitants.
Scope of work
Ailes Marines the Iberdrola company in charge of the development, construction, installation and operation of the offshore wind farm of the bay of Saint-Brieuc awarded the consortium Iemants (subsidiary of Smulders) and EQUANS the contract to construct an offshore substation for the Saint Brieuc offshore wind farm.
The consortium is responsible for the engineering, construction, installation, commissioning and testing of the substation. Iemants is responsible for the engineering and construction of the steel structures for both the topside and jacket. All works will be performed at the Smulders’ production facilities in Belgium and Poland. The topside will be transferred to the EQUANS yard in Hoboken for final assembly. Assembly works of the jacket took place in Vlissingen (the Netherlands).
EQUANS is responsible for the engineering, procurement, integration, construction and testing (on- and offshore) of all LV, MV, HV and auxiliary systems for the jacket and topside of the Saint Brieuc offshore substation.
Key figures and planning
The Saint-Brieuc offshore substation consists of a 63-meter-high jacket of 1,630 T and 315 T piles and a topside weighing approx. 3,400 T. The topside is 55 meters long, 31 meters wide and 23 meters high.
Load out of the topside and jacket took place early June 2022. The sail-away took place 30 June 2022.
