The joint venture formed by Iemants (a subsidiary of Smulders) and EQUANS has won a contract to construct an offshore substation for the Saint Brieuc offshore wind farm, located 16,3 km off the French coast. The contract, awarded by Ailes Marines, an Iberdrola company, consists of the engineering, construction, installation, connection and testing of the offshore substation.
The wind farm 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. It 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.
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.
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.
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 will take place at the Smulders yard in Vlissingen (the Netherlands).
Engineering -and construction works have already been started for the topside and jacket. Sail away of both the topside and jacket is scheduled for the spring/summer of 2022.
