The records have been arranged into five function-based sub-fonds. The first three, MCP-01, St Fergus and the Frigg Transportation System (FTS), contain records created by and necessary to run those installations. It includes procedure manuals, safety records, logs, photographs, surveys, correspondence and reports. The fourth, Total Publications, comprises publications by Total that are about Frigg or the company in general, and that were neither created by the installations nor necessary to run them. The fifth sub-fonds comprises oral history recordings and summaries.
Gas from the several fields utilising the FTS (joining at either the Manifold Compression Platform MCP-01 or formerly TP1 and TCP2 at the Frigg Field) is processed at the terminal. Records concerning these are not within the scope of this project and have not been actively accessioned. This includes records relating to active fields where pipeline bypass works were carried out as a result of Frigg's decommissioning. Those records have remained with the records of the mother field. Due to the interlinked nature of the fields and pipelines, however, there are some records that make reference to those other fields or pipelines.
