A joint venture of Mammoet and Giant Heavy Machinery Services has started working with Sing Da Marine Structure Corporation (SDMS) on the locally-produced jacket foundations for the Greater Changhua offshore wind project in Taiwan.
The joint venture will be performing the assembly, transportation and load-out of the jackets, each weighing approximately 1,200t.
The PTC200-DS Ring Crane will assemble the jackets by first upending the lower jacket structure before installing both the upper structure and transition pieces at a single location.
Seventy-two axle lines of SPMT will then transport each jacket up to 1,200m from the fabrication line to a storage area, Mammoet said.
Four jackets are expected to be simultaneously assembled.
At the end of 2018, Ørsted signed a contract with SDMS to supply 56 jacket foundations for the 900 MW Greater Changhua 1&2a project.
South Korea’s Samkang M&T will deliver 28 foundations and Hyundai Steel Industries the remaining 27 units.
The wind farm will feature 111 Siemens Gamesa 8 MW turbines installed some 35 to 50km off the coast.
