An Austrian offshore crane manufacturer this month announced that its offshore technology will be supplied to GDF Suez E&P UK for application in the North Sea, as part of plans to increase efficiency and reduce operational costs.

The announcement follows a contract with GDF Suez E&P UK, under which Liebherr-Werk Nenzing GmbH, Austria will provide four offshore cranes of the type RL 2650-25 D EX Litronic to GDF Suez E&P UK for the Cygnus gas field project, situated in the southern North Sea.
Offshore cranes can be used for various tasks such as offshore installation works, unloading of supply vessels, pipe transfer, as well as deck and subsea lifts.

The four RL 2650 are self-contained, stand-alone cranes with multiple 360° slewing, Liebherr told OGT. They can achieve boom lengths from 20m up to 54m, in addition to 26500 kilonewton meter (kNm) max platform lift capacity. They avoid power pack overloading and enhance operating efficiency as well as Diesel fuel efficiency, Liebherr says.

All cranes will be operated with Liebherr’s own programmed system, called “Litronic”. This system, Liebherr says, will be continuously improved by implementing new features such as using all crane relevant Data from the ‘LIDAT’ (Liebherr’s new web based universal data aggregation and supervision system) to plan service and maintenance of the crane ahead.

“With the use of this new technology we want to make ‘life’ easier and reduce operational costs for our customer and guarantee Liebherr’s good quality of offshore cranes for which we are also known,” Wolfgang Pfister, head of marketing at Liebherr Nenzing, the maritime arm of Liebherr-Werk Nenzing told OGT.

The four offshore cranes will be built in the Liebherr production facility in Sunderland, UK.  In general it takes 12 months to produce one offshore crane of the RL 2650 type, Liebherr told OGT.

The Cygnus gas field is situated within the UK Continental Shelf in 23m of water. The field is operated by GDF Suez and is the largest to be discovered within the last 25 years in the North Sea’s Southern basin.
