Davenport Downs Compressor Station

Print This Article

The capacity of APA Group’s Carpentaria Gas Pipeline (CGP) is progressively being increased by the installation of additional compressor stations at existing scraper stations along the pipeline.

Davenport Downs Compressor Station is located in Western Queensland and is the second stage of the CGP upgrade. Davenport Downs is a Class 900# station, designed for 175 terajoules per day compression capacity.  The station consists of a Solar Centaur C50 compressor, an inlet filter coalescer, an aftercooler, two 126kilowatt Gas Engine Alternators, gas regulation and filtration skids and various site buildings.

GHD's role in the project commenced during the FEED stage and has continued through detailed design.  During detailed design, the scope of work included all civil and structural design, process design of the station, mechanical design of the piping and equipment interfaces and engineering of equipment items for procurement. 

A variety of GHD teams, including Process Plant & Emerging Technologies, Hydrocarbon Processing, Mining & Industrial Structures and Roads & Highways, collaborated to deliver services for the project.

Hydrocarbon Processing facilities handle products which are flammable and hazardous and often at elevated pressures and temperatures. We have a direct interest in the various aspects of process hazard management – pipeline risk assessments, HAZOP study, SIL/LOPA study, Consequence Modelling of hazardous incidents (e.g. gas dispersion and thermal radiation). Our activities include the revalidation of previously completed process hazard analysis studies.

Community expectations demand that pipelines and facilities are designed and constructed in such a way that the risk of harm to the public is minimised.  Pipelines projects must also be delivered with minimum impact on the environment and cultural heritage whilst providing a return on investment for pipeline owners.

Pipeline and associated facility design and maintenance are subject to stringent codes and regulatory requirements which aim to achieve safe operation through design life.
