Custom Cranes for Walking Jack-Up
In October Dutch crane builder Lagendijk Equipment delivered two electric/ hydraulic cranes for the Van Oord and Fugro Seacore joint venture WaveWalker 1. The custom-designed and built offshore knuckle boom crane and offshore wire crane with lattice boom will operate on board the innovative walking jack-up barge in rough seas, surf zones, beaches, and other intertidal settings in Brazil.
Lagendijk Equipment won the contract for the WaveWalker 1 project in part thanks to a fast turnaround. The tailor-made knuckle boom crane was constructed in just 26 weeks and handed over to her principal on 3 September. Managing Director Peter Lagendijk says the company designed the crane for a harsh marine environment, conforming to GL Class, with recommended operation up to Sea State 5.
The second, a newly designed Electric/ Hydraulic LWC 900 Offshore Wire Crane with lattice boom, is one of Lagendijk’s largest-ever tailor-made projects. It has a lifting capacity of SWL 100 tons @ 6 meters, or SWL 78 tons @ 6 meters in Sea State 5. The design, also conforming to GL classification, is suited for high dynamic forces during subsea grabber operation, with a capacity of SWL 20 tons @ 20 meters below sea level. Van Oord also chose an operating cabin and a constant-tension system on the main winch to reduce dynamic loads on wire rope in both normal and sub-surface operations.
