Four offshore substation topsides and four modular support frames for the 1.5 GW Baltica 2 offshore wind farm have departed Vietnam for Poland following the completion of the load-out and sail-away campaign at PTSC Mechanical & Construction’s (PTSC M&C) yard in Vung Tau.
PTSC M&C said on 14 September that the shipment marks its first offshore substation delivery from Vietnam to Europe.
The company is delivering the substations in a consortium with Denmark’s Semco Maritime, which signed a contract with Baltica 2 developers PGE and Ørsted in June 2023.
The scope covers four substation platforms and four modular support frames, with Semco Maritime responsible for the high- and medium-voltage, SCADA and auxiliary systems and PTSC M&C carrying out the fabrication at its Vung Tau facility. Each substation has a capacity of 375 MW and is equipped with two transformers.
The consortium began manufacturing the substation platforms at PTSC M&C’s yard in November 2024.
The offshore substations will now be transported to the Polish Baltic Sea, where Seaway7 will install them under a transportation and installation contract signed with PGE and Ørsted in March 2024.
At the Baltica 2 offshore wind farm site, located approximately 40 kilometres off the Polish coast between Łeba and Ustka, Van Oord recently completed the installation of all 111 monopile foundations, including 107 monopiles for the project’s wind turbines and four foundations for the offshore substations.
The 1.5 GW offshore wind farm will comprise 107 Siemens Gamesa 14 MW turbines and is scheduled for commissioning in 2027.
