Offshore staff
MEISE, Belgium — Sarens has assembled the jackets for the turbines for Ørsted’s Greater Changhua offshore wind farm in the Taiwan Strait, with a planned capacity of 2.4 GW.
Under a memorandum of understanding with Vietnamese fabricator PTSC, Sarens was responsible for assembly and integration of 33 steel jackets for the turbines, with an estimated weight in each case of 2,500 to 2,800 t.
The company used a range of cranes such as a Liebherr LR1750, with a lifting capacity of up to 750 t, and a Demag CC2800-1 crawler crane with a lifting capacity of 600 t, both among Sarens’ Vietnam equipment pool. It also employed a CC6800 from Thailand, capable of lifting up to 1,250 t, with a maximum boom extension of 150 m.
However, the main integration crane was the SGC-90, also known as Little Celeste, which was imported from France. This is said to be the world’s first ring capable of operating entirely on electricity, with a maximum lifting capacity of 1,650 t and a maximum load moment of 99,000 Tm.
Erection of the 33 jackets was completed within one year, including setup and installation, at the PTSC yard. Lifting was performed in tandem.
