Hanwha Ocean has secured approval in principle (AiP) from ABS for the concept design of a 60 MW floating data center, extending the Korean shipbuilder's offshore engineering franchise into power-hungry digital infrastructure.

The approval covers only the concept stage. Hanwha Ocean has disclosed no construction order, no deployment location and no project timeline, which sets firm limits on how quickly the design can translate into steel on the water.

The 60 MW concept pairs Hanwha Ocean's shipbuilding and offshore engineering expertise with infrastructure designed to sidestep the land, power and cooling constraints that increasingly box in conventional land-based data centers. The company said it intends to combine its marine capabilities with Hanwha Group's experience across energy and data.

The agreement was signed by senior executives from both sides, including Young-chang (James) Shon, Hanwha Ocean Chief Technology Officer, Product & Technology Strategy, and Joshua Divin, ABS Senior Vice President, Marine Business Development.

Why it matters for shipping

For a yard fighting for orderbook visibility amid stiff Korean and Chinese competition, floating data centers open a new product category that draws directly on existing competencies: hull design, offshore platform engineering, marine systems integration and power distribution at sea. Each converted or purpose-built unit would represent a large, high-value fabrication contract in the same weight class as offshore production units.

The concept also carries implications for marine services demand. A 60 MW floating facility requires towage, positioning, class survey, periodic drydocking and long-term offshore support — recurring revenue streams for owners, operators and class societies rather than one-off construction work alone.

For Hanwha, the move aligns the yard with the broader convergence between offshore energy and digital infrastructure, where AI-driven demand for compute is colliding with grid and land constraints in major data center markets.

ABS builds a pipeline

The Hanwha Ocean approval forms part of a wider push by ABS into floating data center technology. Over the past year, the classification society has issued approvals for conceptual floating data centers ranging from 50 MW to 200 MW in capacity, indicating that multiple developers are moving designs through early-stage review even before commercial commitments materialize.

ABS also published a study in 2025 examining the potential use of nuclear power for floating data centers, signaling that the class society sees propulsion and generation technology choices — including small modular reactors — as a live question for the sector rather than a distant one.

"Interest in floating data centers is growing, and the industry is looking for practical ways to take new infrastructure from concept to reality," said Patrick Ryan, Senior Vice President and Chief Technology Officer at ABS. Ryan highlighted Hanwha Ocean's track record in developing complex offshore structures as directly relevant to the emerging sector.

The gap between concept and contract

The distance between an AiP and a delivered asset remains the sector's central hurdle. Approval in principle validates that a concept meets class requirements at the design level; it does not commit anyone to construction. No floating data center of this scale has yet reached a firm build order under the ABS approvals issued to date, and the Hanwha Ocean project is no exception.

Still, the pace of approvals — several concepts between 50 MW and 200 MW inside twelve months — suggests classification groundwork is being laid ahead of commercial decisions. If power and land constraints continue to tighten in key data center markets, yards with offshore credentials such as Hanwha Ocean will be positioned to convert class-endorsed concepts into fabrication contracts, with ABS indicating it will keep evaluating larger and more technically ambitious designs, including nuclear-powered variants.
