Huisman has started the final factory acceptance testing of its first 900mt Rope Luffing Knuckle Boom Crane, now called the ‘Hybrid Boom Crane’, at the quayside of the Huisman China Production facility in Zhangzhou.
The crane was fully assembled in the main assembly hall and upended by Huisman’s 2,400mt Quayside Crane. In the coming weeks, the crane will undergo an intensive factory acceptance testing program, after which it will be shipped to Hyundai Heavy Industries in Ulsan, South Korea. The crane will then be installed, commissioned and tested on board Subsea 7’s Seven Arctic, Huisman informed.
The hybrid boom design combines the advantages of regular pedestal cranes and traditional knuckle boom cranes. The main and knuckle boom have a low construction weight. With the knuckle boom in an extended position the crane offers a high lifting height with full lifting capacity, which is normally available with a fixed boom. The hybrid boom design provides a low suspension point and reduction of load swing, the company explained.
The crane is fully electrically driven. A real-time heave compensation and shock absorbing system further increases the operational weather window for safe and accurate installation of subsea infrastructure components, Huisman added.
