ABS has issued an Approval in Principle (AIP) to Seatrium for the company’s offshore substation (OSS) design, described as a next-generation offshore HVAC platform engineered for scalability.

Seatrium has built several offshore converter platforms for offshore wind farms and grid connections over the years, including the now-operational DolWin epsilon in Germany and the OSS for the Greater Changhua 2b and 4 offshore wind farm in Taiwan, and was recently contracted as part of a consortium with GE Vernova to build the platform for the new BalWin5 grid connection in Germany.

Seatrium says that its substation design, OSS-500A, is built with a modular architecture and engineered to the highest international standards by leveraging a class-proven design.

The offshore substation features 500 MW modules and offers flexibility across a wide range of water depths, grid configurations, and project scales. OSS-500A integrates robust structural design, advanced electrical systems, and future-ready expandability to support growing offshore wind capacities, according to the company.

“This is a new offshore substation approach that supports large-scale renewable energy generation while meeting rigorous international safety and performance standards”, said Michael Kei , ABS Vice President, Technology.

“This OSS-500A AIP with ABS affirms our technical expertise, compliance with rigorous class standards, and commitment to delivering green solutions – providing clients with confidence in the reliability and quality of our offerings” , said Aziz Merchant , Executive Vice President, Engineering, Technology & New Product Development, Seatrium.
