Huisman to develop 4,000 tonne mast crane

Huisman, designers and manufacturers of heavy construction equipment are designing an offshore mast crane and pipelay tower weighing about 4,000 tonne for Heerema’s deep water construction vessel. This crane design was determined due to the small footprint and construction weight. However, the mast crane will be used for J-lay and reel-lay operations in ultra deep water. The new concept is used for rigid pipe-laying as it allows onshore spooling of reels while offshore pipe-laying continues, eliminating the need for a large spool base. Also, the reels are removable; in order to free deck space, while operating in J-lay or crane barge mode. Contact: Huisman Equipment. Tel: +31-10-245 2222. Fax: +31-10-245 2220.
