NORWAY’s second largest offshore gas field, Ormen Lange, has started production from the Norwegian Sea, with gas set to flow along the world’s longest subsea pipeline to the UK, writes Martyn Wingrove.
Field operators Norsk Hydro and Shell are using gas and condensate volumes from the field to test pipelines and process plant at the Nyhamna terminal, near Molde, before gas is sent down the new 1,200 km long Langeled pipeline to the Easington terminal in eastern England.
‘Completion of this breakthrough development will make Norway the world’s second largest exporter of natural gas,’ said Hydro.
‘Ormen Lange is expected to meet 20% of the UK’s requirements. Exports to the UK and the European continent will be moderate at first, and will increase over the autumn.’
Hydro has developed Ormen Lange with subsea wells in water depths of around 800 m to 1,100 m, linked to Nyhamna through a 120 km long pipeline.
Shell will manage operations on the project from December 1. Other partners in the project include Statoil, which is acquiring Hydro’s energy assets, the Norwegian state company Petoro, US major ExxonMobil and Denmark’s Dong Energy.
It is a technically complex project, involving several ships, including a drillship, survey, subsea construction and pipeline haul vessels. There are two more phases planned for the field that will involve more wells, pipelines and a subsea gas compression system.
