TenneT TSO B.V. has selected joint venture ENGIE Fabricom – Iemants (a subsidiary of Smulders) to construct an offshore transformer station for the Hollandse Kust Noord wind farm zone. The joint venture is also the preferred contractor for TenneT’s next offshore projects, the Hollandse Kust West Alpha and Beta platforms.

The scope of work for the joint venture on the Hollandse Kust Noord project consists of engineering, procurement, construction, offshore installation, connection and testing for the offshore transformer station. This offshore transformer station consists of a 45-meter-high jacket of 1,930 T and 870 T piles to be placed in 24-metre water depth and a topside structure consisting of 4 decks weighing approx. 4,100 T. The topside structure is to measure 47 metres long, 35 metres wide and 25 metres high (excluding antenna tower and top deck crane).

Iemants, a subsidiary of Smulders, is responsible for the engineering, procurement and construction of the steel structures for both the topside and jacket. All works will be performed 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 Autumn 2021. The topside is scheduled to leave the yard in Hoboken in Spring 2022.

Guus Siteur, project lead HKN/HKWa platform at TenneT, said: "With this contract TenneT builds upon its strategy for cost effective, standard offshore transformer stations to enable the Dutch energy transition. During the tender phase additional effort was taken in respect of environmental, quality and safety aspects. TenneT is looking forward to a positive cooperation the ENGIE Fabricom – Iemants joint venture which has long experience in the offshore transformer station construction field."

We are confident that the expertise of TenneT in these highly standardized 700 MW offshore transformer stations, in combination with the wide experience of the Joint Venture in developing offshore transformer stations over the last decades, will result in a safe and successful project conclusion. We are looking forward to working together with TenneT and wish to develop a long-lasting relationship, in the offshore wind industry.”
