Lagendijk Equipment revealed the completion of an order from Van Oord for two electric/ hydraulic cranes to be installed on the innovative walking jack-up barge WaveWalker 1. Van Oord is a leading international contractor in dredging, marine engineering, and offshore oil, gas and wind projects.
The first, Lagendijk’s LKB 13.0 / 20.0 – 10.0 Offshore Knuckle Boom Crane, is designed for a harsh marine environment, conforming to GL Class, with recommended operation up to Sea State 5. It has a lifting capacity of 10 tons @ 20 meters and constant tension on the main winch; its hydraulic grab function works to 20 meters below sea level. This tailor made knuckle boom crane was constructed in just 26 weeks and handed over to her principal last September 3rd.
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. Delivery is planned in October 2012.
WaveWalker 1 operates in conventional four-legged mode, or as an eight-legged self-contained walking jack-up platform, with bi-directional movement when elevated. It was developed jointly by Van Oord and Fugro Seacore to operate in rough seas, surf zones, beaches, and other intertidal settings.
Lagendijk Equipment, a family-owned business for more than a century, is a leading technology source for the offshore, pipe-laying, dredging, and shipping industries.
