Oseberg Transportation System (OTS) is a comprehensive system that started up in 1988 for transport of Oseberg crude oil to the Sture terminal for further handling and offloading into crude oil tankers.
Today the terminal receives crude oil and condensate via pipelines from the Oseberg area and from the Edvard Grieg and Grane areas. The terminal handles both stable and unstable crude oil. The unstable crude oil is stabilised to sales quality while the natural gas liquids (NGLs) are fractionated further and mainly piped to Vestprosess at Mongstad for further processing to propane and butane.
The plant has two jetty facilities which can accommodate oil tankers up to 320,000 dead weight tonnes (dwt), five crude oil caverns with a capacity of one million cubic metres, a 60,000 cubic metres LPG cavern and a 200,000 cubic metres ballast water cavern.
The crude oil sales qualities Oseberg Blend and Grane Blend are exported from the Sture terminal.
