Mammoet-Giant has been selected by Ørsted Taiwan to marshal 66 wind turbine jackets for the 920 MW Greater Changhua 2b and 4a offshore wind farms. The project marks the first large-scale use of suction bucket jacket (SBJ) foundations in the Asia-Pacific region. To manage the challenges of Taichung Port’s significant tidal variations, Mammoet-Giant deployed its 5,000-tonne capacity SK350 ring crane.
Jackets, each weighing 2,400 tonnes and standing 80 metres tall, were lifted directly from deck carriers and placed onto quay supports. This avoided reliance on tidal conditions and reduced mobilisation requirements, as only part of the ring track was needed for the lifting operation.
Self-propelled modular transporters (SPMTs) were then used to move the jackets to temporary storage areas on bamboo-supported steel foundations. For the final load-out, the process was reversed, with jackets lifted back onto deck carriers in batches for transport to offshore installation vessels.
By minimising dependence on weather and tidal windows, the approach reduced project risks, shortened vessel charter time and improved operational safety.
