Mammoet-Giant has successfully completed the marshalling and loadout operations of 66 jacket foundations for the Greater Changhua 2b and 4a offshore wind farms in Taiwan. The project supports Ørsted’s 920 MW wind development, one of the most significant renewable energy undertakings in the Asia-Pacific region.
The entire campaign was executed at Taichung Port, a key logistics hub for Taiwan’s offshore wind sector. The project required precise coordination to manage complex lifting, transport, and storage of large-scale suction bucket jacket (SBJ) structures—each weighing approximately 2,400 tonnes and reaching up to 80 meters in height.
Instead of relying on traditional Roll-on/Roll-off methods, Mammoet-Giant implemented a customized lifting-based marshalling solution using the SK350 ring crane, one of the world’s largest land cranes with a lifting capacity of up to 5,000 tonnes. This approach allowed each jacket to be lifted directly from deck carriers onto the quay, minimizing dependence on tidal conditions that can fluctuate by as much as six meters in the region.
Following offloading, the jackets were transported by self-propelled modular transporters (SPMTs) equipped with 96 axle lines to a temporary storage area supported by steel and bamboo structures. When ready for loadout, the same SPMT units returned the jackets to the quayside, where the SK350 lifted them onto deck carriers in batches for offshore installation.
This innovative workflow enabled greater schedule predictability, reduced vessel waiting times, and optimized overall project efficiency. By minimizing reliance on tidal and weather windows, Mammoet-Giant’s solution significantly lowered project risk while improving safety and environmental control across the port operation.
The Greater Changhua 2b and 4a project marks a key milestone in Taiwan’s ambition to expand its offshore wind capacity and demonstrates the critical role of advanced heavy-lift logistics in enabling large-scale renewable infrastructure.
