Semco Maritime and PTSC Mechanical & Construction (PTSC M&C) have been awarded an engineering, procurement and construction contract for the offshore substations for the Baltica 2 project.
PGE Group and Orsted have awarded the consortium the contract that consists of four 375MW offshore substations for the development.
Semco Maritime and PTSC M&C will be supported by primary sub-contractors ISC Consulting Engineers and Hyundai Electric.
Baltica 2 is located in the southern part of the Baltic Sea approximately 40km off the Polish coast and scheduled for commissioning by end of 2027. The offshore wind farm will have a capacity of approximately 1.5GW.
The contract includes design, engineering, procurement, construction, and commissioning of the four offshore substations, which will be manufactured at PTSC M&C’s yard in Vungtau, a port city in south Vietnam, which is the heart of the country’s offshore oil and gas industry.
Semco Maritime will design, procure and install high and medium voltage, SCADA and auxiliary systems supported by ISC Consulting Engineers and Hyundai Electric.
The contract will be executed in 2023-2026.
“We are proud that Poland’s largest electricity provider and the global leader in offshore wind have awarded our consortium a landmark order in one of the largest offshore wind projects in the world,” said Semco Maritime vice president renewables Frank Holm.
“Together with our partner PTSC M&C, we look forward to contributing to the growing offshore wind industry in Poland, leveraging our experience from offshore substation projects and cooperating closely with the PGE Group and Orsted to bring green, affordable, and reliable energy ashore for millions of consumers.”
