TenneT has selected the joint venture EngiE Fabricom – Iemants (subsidiary of Smulders) to construct an offshore transformer station for the Hollandse Kust (Noord) wind farm zone.
The offshore transformer station consists of a 45-meter-high jacket of 1,930 T and 870 T piles to be placed in 24-meter water depth and a topside structure consisting of 4 decks weighing approx. 4,100 T. The topside structure is 47 meters long, 35 meters wide and 25 meters high (excluding antenna tower and top deck crane).
Iemants is responsible for the engineering, procurement and construction of the steel structures for both the topside and jacket. All works will be performed inhouse, at the Smulders’ production facilities in Arendonk, Balen and Hoboken (Belgium). The topside will be transferred to the Engie Fabricom yard for final assembly. The jacket will be assembled at the yard in Vlissingen (the Netherlands).
Engie Fabricom, 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 Hollandse Kust Noord offshore transformer station. The engineering, procurement, construction, integration and onshore testing for the topside systems will take place at the ENGIE Fabricom yard in Hoboken (Belgium). For the jacket these activities will take place in Vlissingen.
Engineering works have started, and construction works for the topside and jacket will start in October 2020. Load-out of the jacket is planned for the fall of 2021. The topside is scheduled to leave the yard in Hoboken in the spring of 2022.
