Sembmarine clinches largest offshore renewable project

It secured an agreement consisting of three contracts valued at $2.8b (€2b).

Sembcorp Marine (Sembmarine) and consortium partner GE Renewable Energy’s Grid Solutions have jointly secured a Framework Cooperation Agreement (FCA) to build an HVDC electrical transmission system for TenneT.

Sembmarine said this is their “largest offshore renewable project” to date.

The agreement covers five years with an option to extend another three years. It consists of three contracts, each valued at approximately $2.8b (€2b).

Under the deal, Sembmarine’s consortium will supply high voltage direct current (HVDC) electrical transmission systems for three mega offshore wind farm projects, with a combined capacity of six Gigawatt (GW), in the Netherlands as part of TenneT’s offshore grid acceleration programme. 

Sembmarine will also be involved in the engineering, procurement, construction, transportation, installation and commissioning of three 2GW HVDC Offshore Converter Platforms.

Sembmarine will progressively install the platforms to serve TenneT’s three offshore wind farm projects – the IJmuiden Ver Beta, IJmuiden Ver Gamma and Nederwiek 2 grid connections. 
Construction of the platforms, each comprising a 25,500-tonne topside and a 9,500-tonne jacket foundation structure, will progressively commence from 3Q 2024 at Sembcorp Marine’s Singapore and Batam Indonesia yards. 

Sembmarine’s wholly-owned subsidiary in the UK, Sembmarine SLP, will perform the offshore hook-up and commissioning, including the provision of logistics and warranty support from its base in the UK, as well as the establishment of a European office in the Netherlands.
