Huisman has started with the final factory acceptance testing of its first 900 mt 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 2400 mt Quayside Crane. In the coming weeks, the crane will undergo an intensive factory acceptance testing programme, 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.

Hybrid Boom Crane

Huisman decided to change the name of this new hybrid type crane from Rope Luffing Knuckle Boom Crane to Hybrid Boom Crane to better reflect the unique features of the crane. The hybrid boom design combines the advantages of regular pedestal cranes and traditional knuckle boom cranes. Due to the innovative crane design the main and knuckle boom have a low construction weight, therefore the crane practically matches the excellent load curves of a pedestal crane with a fixed boom.

With the knuckle boom in an extended position the crane offers a unique high lifting height with full lifting capacity, which is normally only available with a fixed boom. The hybrid boom design also secures the key advantages of traditional knuckle boom cranes, such as a low suspension point and reduction of load swing. These advantages have made the knuckle boom crane one of the most popular tools for offshore and subsea construction activities.

Electrically driven

The benefits of the Hybrid Boom Crane extend beyond the boom design. The crane is fully electrically driven. This reliable and environmentally friendly drive system provides precise control over crane and load movements, with low noise levels, reduced maintenance and no risk of oil spills. A real-time heave compensation and shock absorbing system further increases the operational weather window for safe and accurate installation of subsea infrastructure components.

North Sea Offshore & Crane Lifting Conference and OTC

Huisman will demonstrate the features of the Hybrid Boom Crane with a fully operational scale model at the 20th North Sea Offshore Crane & Lifting Conference on 21-23 April 2015 in Stavanger, Norway, and on 4-7 May during the 2015 Offshore Technology Conference (OTC 2015) in Houston, Texas, at their booth 2327.
