Offshore crane

A J D Neuhaus hydraulically
operated 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 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.
