The Oseberg Field Centre encompasses three platforms; Oseberg A, B and D, all of which are connected by bridges in the southern part of the Oseberg field. It also includes the unmanned Oseberg H platform, which is located 8 kilometres northwest of the field centre.
Oseberg A is a concrete platform with process equipment and living quarters, while Oseberg B has a steel jacket and drilling, production and injection equipment.
Oseberg D is a steel platform with gas processing and export equipment. It was connected to the field centre with a bridge in the spring of 1999.
Oseberg H is a modern, cost-effective wellhead platform with a steel jacket. Oil and gas are transported in a multi-phase pipeline from Oseberg H to the Oseberg Field Centre.
Six subsea installations with a total of 21 wells are tied in to the Oseberg Field Centre.
Gas export from the Oseberg Field Centre started on 1 October 2000, ushering in a new era for the Oseberg field.
Transport
Production from the Tune field (gas and condensate) goes to the Oseberg Field Centre. Condensate is sent to the Sture terminal onshore, while the gas is injected in the Oseberg field.
The facility at the field centre is also used to treat oil and gas from the satellite fields Oseberg East and Oseberg South.
Oil from the Oseberg area is routed via the Oseberg Transport System (OTS) to the Sture terminal.
Oil from the Oseberg C, Oseberg South, Oseberg East and Brage installations is also pumped through the same transport system.
The gas is sent to the market via Oseberg Gas Transport (OGT) and the Statpipe system bound for the Continent and through Vesterled to the United Kingdom.
