Ørsted signs contract with Petrovietnam Technical Services Corporation to build new generation of offshore wind foundations

Global offshore wind leader Ørsted has awarded a major contract to Petrovietnam Technical Services Corporation (PTSC) to manufacture and supply foundations for the 920 MW Greater Changhua 2b and 4 offshore wind farms in Taiwan.
The contract announcement follows Ørsted’s final investment decision, taken in March 2023. The wind farms are now under construction and are set to be some of the largest offshore wind projects in Asia Pacific.

Under the agreement, PTSC will produce 33 suction bucket jacket (SBJ) foundations. These components are an environmentally friendly solution using Ørsted’s state-of-the-art bespoke designs. 

The foundations will be installed at Greater Changhua 2b and 4 by the end of 2025. The project is estimated to use 70,000 tons of steel and create thousands jobs at PTSC and other contractors in the supply chain.

The signing ceremony was held on 19th May at PTSC’s manufacturing facility in Ba ia–Vung Tau. It was attended by representatives of the Central Committee's Economic Commission, the National Assembly’s Economic Committee, Ba Ria - Vung Tau Local authority, other relevant authorities from Central and Provincial level, the Embassy of Denmark in Vietnam, Vietnam Oil & Gas Group and leaders from Ørsted and PTSC.

Jonas Bak Solhøj, Development Director for Greater Changhua 2b and 4, Ørsted, says:

“As the global leader in offshore wind we are pleased to work with Petrovietnam Technical Services Corporation to build the offshore foundations to the highest standards for safety and quality. These suction bucket jacket foundations will be the first deployment of this technology in Asia Pacific. They will underpin the generation of reliable green energy for decades ahead.”  

Pascal Langeais, Head of APAC Procurement & Supply Chain Development, Ørsted, says:

“Ørsted’s agreement with Petrovietnam Technical Services Corporation demonstrates the strength of Vietnam’s emerging supply chain for large-scale renewable energy projects. PTSC has a highly skilled workforce and proven manufacturing capabilities. Through our close collaboration, Ørsted and PTSC will enable the timely production of state-of-the-art foundations infrastructure for Ørsted’s largest and most advanced offshore wind farms in Asia Pacific.”

Le Manh Cuong, President & CEO of PTSC, says: 

“This contract represents a remarkable milestone in PTSC’s history of establishment and development. PTSC has transformed and expanded its production method from single tailor-made unit to serial production with large quantity, high productivity and closed production line which are totally different from traditional oil and gas projects. This is the first time Vietnam has a huge export contract in the new industry of offshore wind power. Throughout the execution of the contract, jobs will be created for thousands of PTSC’s employees and it will also contribute to the establishment of the supply chain in Vietnam for offshore wind power projects.”
