Intro
The Trent Compression Platform is a fixed steel compression facility installed in 2005 and bridge-linked to the Trent Production Platform in the Trent gas field, Southern North Sea. It was added to provide gas compression to support production and export. The installation is part of the Trent complex feeding gas export infrastructure to shore before cessation of production.
Field
The Trent gas field lies in Block 43/24a in the UK Southern North Sea with dry conventional gas in Carboniferous sandstones. Discovered in the early 1990s and first producing in 1996, Trent was developed with a production platform and later compression platform to sustain output and export through the Esmond Transmission System to Bacton.
Facilities
The Trent Compression Platform is a four-leg fixed steel structure with a ~30-m×30-m deck holding compression trains and associated equipment. It is bridge-linked to the Trent Production Platform (TP), receiving multiphase gas flows for intermediate pressure boosting before export. Topside comprises gas compressors with turbine/driven drivers, intercoolers, lube systems, control room and electrical distribution. The platform includes safety systems such as emergency shutdown (ESD), fire & gas detection, and isolation valves that integrate with TP. Utilities include local power generation (for instrument power and control systems), HVAC, instrument air, and communication links to Trent for coordinated operation. Produced gas from compression is exported via the ETS 24- pipeline to the Bacton Gas Terminal. Chemical injection points support flow assurance and corrosion control. The structure was designed for long-term offshore compression with slug catchers and coolers sized for the expected flow regime. Cessation of production and suspension documentation was approved in 2023, and decommissioning planning is underway.
