ABS issued approval in principle (AIP) to Seatrium for its next-generation offshore substation (OSS) design, featuring 500-megawatt OSS modules.

“Offshore substations play a critical role in transferring power from the wind turbines via inter-array cables, transforming it into high voltage and exporting it through subsea cables back onshore. This AIP marks a significant milestone in offshore wind energy development and advances the industry’s commitment to safe, efficient, and sustainable energy solutions,” said Robert Langford, ABS Vice President, Global Renewables.

“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 Ltd.
