Nederwiek 1 offshore substation to be built in Malaysia

Malaysia Marine and Heavy Engineering Holdings Berhad (MHB), through its wholly owned and major subsidiary Malaysia Marine and Heavy Engineering Sdn Bhd (MMHE), will build the offshore substation (OSS) high voltage direct current (HVDC) platform for the Nederwiek I offshore wind farm connection in the Netherlands.

The OSS platform comprises a topside, weighing approximately 30,000 tonnes (including equipment) and a jacket, weighing approximately 10,000 tonnes. Under this project, MHB is responsible for the construction engineering, fabrication, mechanical completion, load out and sea fastening, and architectural works on an engineering, procurement and construction (EPC) basis. The duration of the project is approximately 36 months, with fabrication to begin in 2025 and completed by 2028.

MHB received the contract from Petrofac International (UAE) LLC (Petrofac). It is the second offshore wind contract from Petrofac for the Netherlands, having already secured the first subcontract for the IJmuiden Ver Alpha project in November 2023 from Petrofac. In addition, MHB and Petrofac will collaborate towards the possibility of another OSS of similar size.

Both projects are part of TSO TenneT’s 2GW offshore grid connection programme. This new standard combines TenneT’s extensive expertise in offshore grid connections with a unique transnational approach. With its strong focus on harmonisation and standardisation, it provides a blueprint for future offshore grid connection systems and enables faster deployment. At the same time, the larger capacity of two gigawatts per system reduces the number of grid connections required. Petrofac and Hitachi Energy were contracted to deliver the offshore stations.

The tender for the Nederwiek I offshore wind site is planned for 2025. Last week, Dutch energy Minister Rob Jetten informed the Dutch Parliament on the procedure for the tender. The wind farm is expected to become operational in 2030. Source: MHB Image: TenneT
