Sembcorp Marine and GE Jointly Secure Landmark Offshore Renewables Project to Build Biggest and Most Advanced HVDC Electrical Transmission System for TenneT
Friday 31 March 2023
Sembcorp Marine Ltd through its wholly-owned subsidiary Sembcorp Marine Offshore Platforms Pte. Ltd. (“SMOP”), and consortium partner GE Renewable Energy’s Grid Solutions (“GE”) have jointly secured a Framework Cooperation Agreement (“FCA”) from TenneT TSO B.V. (“TenneT”).
The FCA covers a period of five years with an option to extend another three years. It consists of three contracts, each valued at approximately EUR 2 billion, to supply the 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.
Representing the largest offshore renewables project secured by the Group, Sembcorp Marine’s scope of work, involves the engineering, procurement, construction, transportation, installation and commissioning of three 2GW HVDC Offshore Converter Platforms – the biggest and most powerful of their kind in the industry. The platforms will contribute towards TenneT’s sustainability ambition through its offshore grid development programme, which involves the installation of 40GW of offshore wind energy in the German and Dutch North Seas, to enable Europe to be the world’s first climate neutral continent.
The Offshore Converter Platforms will be progressively installed to serve TenneT’s three offshore wind farm projects – the IJmuiden Ver Beta, IJmuiden Ver Gamma and Nederwiek 2 grid connections. The IJmuiden Ver projects are located about 62 km off the coast of the Netherlands, while the Nederwiek project is approximately 95 km off the coast.
Construction of the Offshore Converter 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. Sembcorp Marine’s wholly-owned subsidiary Sembmarine SLP, based in the UK, will be performing the offshore hook-up and commissioning. This will include 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.
Sembcorp Marine was awarded the contract based on the strength of the Group’s offshore construction track record and expertise in the delivery of renewable wind energy projects. The Company is currently constructing a HVDC Offshore Converter Platform for the Sofia Offshore Wind Farm and a HVDC platform for the DolWin 5 Offshore Wind Farm. This latest contract award is the third HVDC offshore platform project the Company will be delivering. Offshore completion of the platforms are expected from 4Q 2029 to 2031.
