J D Neuhaus hydraulically operated crane delivered for offshore operations

A J D Neuhaus hydraulically operated crane with 80 tonne lift capacity has been delivered for operation on the semisub rig Spitsbergen, designed and built by Aker Solutions for operation on the Norwegian continental shelf.

This advanced rig will be used to find new oil and gas resources in the North Sea, and the JDN crane will be used for the transportation of ‘xmas tree’ assemblies which provide essential flow control, pressure relief, monitoring, feedback and other important functions associated with the wellhead.

Some of the specialised features of the crane include a radio control system, together with a rack and pinion drive providing safe power transmission for both crane and hoist travel movements when operating offshore or as vessel mounted units. Simultaneous control of several hoists is also provided together with signal horn, key switch and much more. A stainless steel switch cabinet with receiver is provided to operate as an electro-hydraulic interface, together with all necessary hydraulic pipework.

The crane provided is a double girder overhead travelling design. Single girder cranes can also be supplied, as well as slewing jib cranes and underslung cranes with special low headroom trolley designs. Synchronised hoist and parallel hoist lifting operations can be accommodated, as well as customised crane adaptations for special purpose requirements.

The explosion proofness of the crane and hoist mechanisms ensure suitability for operation in hazardous areas. Non-lube low maintenance, 100% duty rating and the use of offshore rated paint finishes also endorse these high performance products for offshore operations.
