Millom West comprises a small steel jacket platform hosting wellheads, Xmas trees and basic manifolds. There is no significant hydrocarbon processing on the platform; produced gas flowed via subsea tie-in to the main export pipeline and onshore Calder/Rivers terminal facilities for dehydration and conditioning. Utilities onboard were limited to remote safety shutdown, instrument power and local controls for monitoring, with chemical injection points for corrosion/hydrate control. The installation was designed for unmanned operation with remote monitoring and periodic maintenance visits. Structural and safety systems met UKCS standards with basic fire & gas detection and ESD logic integrated into the broader field control network. Following cessation of production, removal and decommissioning work began in 2022 with heavy-lift accommodation/control vessel support.
