WOSP Background

The West of Shetland Pipeline (WOSP) system consists of a 20 inch trunk line which begins at the WOSP PLEM near Schiehallion field in the Northern North Sea and transports natural gas 188 km (117 miles) to Sullom Voe on the Shetland Isles. 

WOSP is owned collectively by the owners of the Schiehallion, Loyal, Foinaven and East Foinaven fields; each owner company holds divided capacity rights in accordance with its ownership interest. 

WOSP transports natural gas in dense phase. Gas from the Clair field is delivered into the pipeline at the Clair tee midway along the pipeline (105 km from Sullom Voe). Subsequent transportation and processing in East of Shetland Pipeline (EOSP), NLGP and FLAGS/SEGAL systems can lead to the delivery of sales quality gas into the UK National Transmission System at St Fergus in the northeast of Scotland, and the delivery of separated natural gas liquids into either the Shell operator SEGAL system or the onshore section of the BP operated Forties Pipeline System. 

Any 3rd party interested in transporting gas through the WOSP who requires further information as to technical capabilities, including the availability of ullage, or who wishes to discuss commercial terms for the transportation of gas should in the first instance email the WOSP Operator or write to: 

WOSPS Business Manager

We will then forward your enquiry to each of the WOSPs parties who own divided capacity rights.
