A new agreement with Norsk Hydro, operator of the Ormen Lange gas development in the Norwegian Sea, makes Statoil responsible for procurement and delivery of steel line pipe, anodes and pipeline coating from the field to land.
This job covers two production pipelines for unprocessed wellstream running from Ormen Lange to the processing and export plant at Nyhamna in mid-Norway.
In addition come two pipelines for transporting monoethylene glycol over the same route. All these lines will be about 120 kilometres long.
A 3.5-kilometre monoethylene glycol line will also be installed between two of the subsea templates planned for the field.
These contracts are placed as a separate assignment for Hydro under Statoil’s existing frame agreements for such work.
However, they have been awarded in collaboration with the latter company’s project team for the Langeled gas export pipeline.
That facility is due to run from Nyhamna via the Sleipner Riser platform in the North Sea to Easington on the UK east coast.
“This latest job will help to achieve efficient use of resources and good coordination of deliveries between Ormen Lange and Langeled,” says Odd Nøland, head of procurement in the project execution entity.
The multiphase pipelines between Ormen Lange in 850 metres of water and Nyhamna must be weighted in the shallower part of the route and insulated for the deep section.
An insulation coating is also required for the monoethylene glycol lines.
Shell will take over from Hydro as production operator of Ormen Lange when the field comes on stream, which is scheduled for October 2007.
