Oil & Gas

Share on:

GHD has the experience and multidisciplinary engineering resources to handle the entire life cycle of oil and gas processing and pipeline projects: from conceptual design/routing to detail engineering and commissioning. We understand the variability and complexity in handling hydrocarbon gases and liquids and has designed projects that included Coal Seam Gas(CSG), natural gas, crude oil, refinery products and natural gas liquids. We work collaboratively with our client from onset of the project, beginning with an evaluation of the options. As projects progress from concept to detail design, we focus on meeting the project objectives and creating value for the client.

Hydrocarbon processing facilities handle products which are flammable and hazardous, often at elevated pressures and temperatures. GHD delivers both greenfield developments and brownfield plant expansion or plant debottlenecking projects. Our experience includes a large number of successful projects for CSG, conventional natural gas, Liquefied Petroleum Gas (LPG), refineries and other hydrocarbon processing facilities.

Community expectations demand that pipelines and facilities be designed and constructed to minimise the risk of harm to the public . Pipelines projects must also be delivered with minimum impact on the environment and cultural heritage, whilst providing a return on investment for pipeline owners. Our team is experienced in identifying and managing these concerns.. We coordinate with regulators and environmental, cultural, land service and legal professionals to achieve a design that balances the impact to the public, environment and cultural resources with the project goals.

  • Oil and gas well head and well pad systems

Davenport Downs Compressor


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.

Jackson – Moomba Oil Pipeline


The objective of the Jackson – Moomba pipeline from Jackson in southwest Queensland to Moomba in north eastern South Australia is to optimise the transport of oil from Jackson fields to Santos’ existing Port Bonython facility just north of Adelaide. 

GHD provided Engineering, Procurement and Construction Management (EPCM) for the oil pipeline and facilities. Which had an initial operational capability to pump 2,880 m3/d (18,000 bpd).

Munmorah Gas Pipeline Storage Project


Jemena’s Munmorah Gas Pipeline supplies and stores gas for the 667 MW Colongra Gas Turbine Station near Newcastle, NSW.  The “linepack” pipeline was the first of its kind in Australia and is also the largest diameter licensed gas pipeline in Australia at 42”.  The project included a pressure regulation station which contains the largest water bath heater in Australia.  GHD provided engineering design from feasibility studies through to detailed design and provided support during construction (by Diona).

The pipeline service is unique as it provides fuel gas for the “peaking” power station which is only brought online during times of peak electricity demand.  While the power station is offline, the pipeline continues to receive gas over a 24 hour period and acts as a storage vessel.  As the instantaneous fuel demands exceed the pipelines capacity to supply gas when the power station comes online, the power station draws down on the stored gas (linepack) in the pipeline over a 3 to 5 hour period.  This allows the Owner freedom to purchase and store gas while the spot price is low and supply it during peak periods when the prices are high, therefore maximizing return.

Sydney Primary Loop


Jemena’s Sydney Primary Loop (SPL) is a 29km DN500 pipeline which runs through south western suburbs of Sydney from a connection to an existing section of the DN550 primary loop pipeline at Casula and ties in into the existing DN550 primary main pipeline at Marrickville.  The SPL pipeline connects two major Jemena Gas Networks primary mains, thus enabling continuity and reliability of gas supply if the supply on either is interrupted.  The SPL pipeline also provides further opportunity for development of the gas distribution network in Sydney area.

The facilities and stations on the SPL pipeline include Automatic Line Break (ALB) main line valve stations, a Primary Regulator Station (PRS) at Moorebank and a Trunk Receiving Station (TRS) at West Hoxton.  GHD was selected by Jemena to undertake engineering design and construction support for the pipeline and associated stations.

Vital Inspections for Offshore Gas Platform


A demanding inspection schedule has helped the North West Shelf Venture’s third offshore gas production facility, the new Angel Platform, reach completion off the north-west coast of Australia.

The remotely operated Angel gas and condensate processing platform stands in 80 metres of water about 50 km east of the Venture’s existing North Rankin A production facility. Hydrocarbons will be produced through one processing unit with a capacity of up to 800 million standard cubic feet of gas a day and up to 50,000 barrels of condensate a day.
