In order to allow for the development of the North East Frigg and Odin Gas Fields, an uprating of the Frigg Field Transportation and Treatment system was required. This uprating involved work on the Frigg Field, the North Sea Platform, Manifold Compression Platform O1 (MCP01) and the shore terminal at St Fergus in Scotland. The subject matter of this paper relates to the work carried out on MCP 01. MCP 01, 110 miles offshore, is the centre of a gas collection system receiving gas from the Frigg, Piper and Tartan fields, and transporting this gas to the Total Oil Marine shore terminal at St Fergus. The Frigg gas comes to the MCP 01 by means of twin 32'' diameter pipelines of API 5LX-65 material and that from the Piper/Tartan fields via an 18'' diameter API 5LX-60 line. The gas is transported onshore via twin 32'' diameter sub sea lines of API 5LX-65 material. The maximum throughput of gas to St Fergus was in the region of 64 MCM/day and in order to carry the extra gas from the Norwegian sector it was required to install, on MCP 01, 2 x 28,000 MW compression sets. The installation of these compressors involved an upgrading of existing utilities and processing facilities, living accommodation and extra life saving appliances.
