In order to provide reliable solutions for subsea installation in increasingly deeper water and offshore construction in severe weather conditions, Huisman, the worldwide specialist in lifting, drilling, and subsea solutions, introduces a new patented crane type during this year’s OTC: the ‘Rope Luffing Knuckle Boom Crane’. These new active heave compensated (AHC) cranes provide unparalleled performance by combining the benefits of a normal Rope Luffing Crane and a traditional Knuckle Boom Crane. As such it offers a high lifting height and a large capacity at outreach. The main hoist system, the patented anti-twist device, and the electric drive system really set these cranes apart from other cranes in the market. The capacities of the new cranes range from 400 up to 1,200 ton and up to 5,000 meter water depth. The first crane of this type, a 900 ton Rope Luffing Knuckle Boom Crane for Subsea 7’s ‘Seven Arctic’, is scheduled for delivery in 2016. A model of this vessel including the crane will be presented at the OTC Huisman booth, no. 2327.
