Havtil (the Norwegian Ocean Industry Authority) has authorized trunklines operator Gassco and Norske Shell to start up/use new facilities serving the Ormen Lange gas-condensate field phase 3 development.

The compression system structure preparing to be installed 900 meters below the surface of the sea.
Ormen Lange began production in 2007. Water depths in the area vary from 800 to more than 1,100 m.
The field’s well stream is transported in two multiphase pipelines to the Nyhamna terminal for processing, followed by exported through the Langeled pipeline to Easington on the English east coast.
Phase 3 involves adding subsea compression, powered by two 120-km long cables connected to the Norwegian grid, to increase the recovery rate from the field from 75-85%.

Havtil has also approved BP’s requests to dispose of platform structures in the southern Norwegian North Sea.
One of the consents applies to the steel jacket of the former Valhall PCP (process and compression platform).
The other covers the Hod A platform, 13 km south of the Valhall field in 72 m water depth. The facility exported production to the original Valhall field complex between 1990 and 2013.
It has since been replaced by a new unmanned wellhead platform (Hod B), which entered service in 2022.
