A JD Neuhaus hydraulically-operated crane, with 80 tonne lift capacity, has been delivered to the semisub rig Spitsbergen.
The rig, designed and built by Aker Solutions for the Norwegian continental shelf, is to be used to find new oil and gas resources in the North Sea.
In operation, the crane, which is a double girder overhead travelling design, will handle the xmas tree assemblies that provide for flow control, pressure relief, monitoring and feedback functions at the wellhead.
Features include radio control and a rack and pinion drive that provides safe power transmission for both crane and hoist travel movements – several of which can be handled simultaneously.
As for the controls, a stainless steel switch cabinet houses the electro-hydraulic interface, together with the hydraulic pipework – and all equipment has been certified explosion proof. The crane has also been designed for non-lube low maintenance, with 100% duty rating.
