Intro
Vestprosess is not a platform but an onshore/offshore combined pipeline and processing system in western Norway handling natural gas liquids (NGL) and condensate transport. It connects gas processing infrastructure from Kollsnes and Sture to Mongstad for fractionation and stabilisation; it has been in operation since 1999.
Field
Vestprosess is a transport and processing system for NGL (wet gas) and condensate on the Norwegian continental shelf, linking the Kollsnes gas plant and Sture oil terminal with the Mongstad refinery/processing complex via pipeline. It functions as regional midstream infrastructure rather than a field; it supports multiple offshore fields via onshore facilities that handle liquids extracted from gas processing.
Facilities
Vestprosess consists of a ~56-km pipeline network transporting NGL/condensate from Kollsnes (via Sture) to Mongstad, where fractionation into products (propane, butane, naphtha) and storage occur. The system comprises pipeline assets, pumping stations, processing units for separation and fractionation, storage caverns, and export interfaces. It integrates with Norway’s broader hydrocarbon midstream, feeding refined products to export lines or local markets. Utility systems include control and metering stations, safety systems for handling volatile liquids, and connections to refinery utilities. This infrastructure is stable over time and central to handling liquids from the Norwegian continental shelf’s gas output.
