Singapore shipyard group Seatrium has secured approval in principle (AiP) from the American Bureau of Shipping (ABS) for a 500MW offshore substation design.

The substation was engineered for scalability and is made using a modular framework. It has 500MW modules and can be modified for different water depths and project sizes.

This is Seatrium’s first OSS AiP for an HVAC platform. The company stated that this was underscoring Seatrium’s commitment to advancing renewable solutions.

The OSS-500A offers flexibility across a wide range of water depths, grid configurations, and project scales. It also integrates robust structural design, advanced electrical systems, and expandability to support growing offshore wind capacities.

“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 VP of global renewables.

“This is a new offshore substation approach that supports large-scale renewable energy generation while meeting rigorous international safety and performance standards,” added Michael Kei, ABS VP of technology.
