Technical Description

The Frigg UK Pipeline commences at the TP1 bypass spool close to the decommissioned Frigg Field facilities and runs to the Frigg UK Terminal at St Fergus. It was commissioned in 1977 and has been in continuous service since that date. The pipeline is 362km long and is of 32” diameter.

A separate 110 km long, 24" diameter pipeline between the Alwyn North Field and the TP1 bypass spool forms part of the Frigg UK System and is owned by Total E&P UK Limited. 

An 18" pipeline from the Flotta Catchment Area enters the system via a sub-sea connection in the vicinity of the decommissioned MCP-01 platform. This is located in UKCS Block 14/9. There are also tie-ins from the Bruce, Ross, Captain and Buzzard fields.

The SIRGE pipeline runs from the Shetland Gas Plant (SGP) at Sullom Voe on Shetland to a subsea tie-in on the FUKA Pipeline at the MCP01 bypass valves.

The nominal capacity of the 32" pipeline is 36 MMscm/d. The actual capacity is a function of gas source location and compositions.

A new field tie-in can be achieved by either a hot-tap or by an inserted tee at any point along the main 32" pipeline. In addition, entry can be made via any of the facilities tied into the pipeline or at the TP1 or MCP01 bypass spools.
