XMAS tree handling

A J D Neuhaus hydraulicallyoperated crane with 80t 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. The rig will be used to find new oil and gas resources in the North Sea, and the JDN crane will be used to transport 'xmas tree' assemblies.

The crane, a double girder overhead travelling design, features 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 provided.
