Engineering company TWD has completed its first joint project with SK Oceanplant, marking a new collaboration focused on offshore wind logistics. The scope covered the conceptual development and detailed design of seafastening grillages for transporting jackets destined for the Fengmiao I Offshore Wind Farm, shipped from South Korea to Taiwan.

The completion of this work supports the delivery programme for the Fengmiao jackets, underlining the effective coordination between SK Oceanplant’s manufacturing and logistics capabilities and TWD’s transport engineering expertise. Multiple jackets are scheduled for shipment as full or semi-assemblies, with load-out operations planned to commence at the end of 2025 and continue throughout 2026. All movements will be executed using Self-Propelled Modular Transporters (SPMTs).

Given the varying geometries and weights of the jacket components, each unit required a tailored seafastening design. TWD adopted a solution that balanced weight optimisation with operational efficiency, while maintaining structural integrity during load-out and sea transport. A key feature of the design is the use of bolted interfaces instead of welding to the jackets, allowing for fast, safe handling and ensuring the entire operation remains fully reversible.

Despite demanding conditions, including high sea states and the significant mass of the structures, TWD delivered a robust and efficient seafastening solution. The project demonstrates how the combination of SK Oceanplant’s fabrication experience and TWD’s engineering approach can effectively address complex offshore wind transport challenges, laying the groundwork for future joint projects in the sector.
