The Comet Ridge to Wallumbilla Pipeline Loop (CRWP Loop) is a transmission pipeline located in South-east Queensland. The pipeline is owned by GLNG, which is a joint venture between Santos, Petronas, Total and Korea Gas Corporation (KOGAS).

The Comet Ridge to Wallumbilla Loop is 119 km in length and has a diameter of 600 mm. The pipeline’s daily capacity is 750 TJ.

The CRWP loop links the Fairview gas plant at Comet Ridge with the Wallumbilla gas hub near Roma in Queensland. The CRWP Loop runs parallel to the CRWP, and although both pipelines connect at the Wallumbilla gas hub, they can be operated independently. It is also connected to GLNG’s Roma Underground Gas Storage Facility. Unlike the CRWP, the CRWP Loop is designed only to transport gas in one direction. Its sole purpose is to deliver gas in a northerly direction from GLNG’s Fairview, Arcadia and Comet Ridge coal seam gas fields and the Roma Underground Gas Storage Facility in the Bowen-Surat basin, to GLNG’s gas transmission pipeline for transport to its LNG export facility at Gladstone. 

The CRWP Loop is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Part 10 of the National Gas Rules (NGR). It was previously subject to the access regime for non-scheme pipelines under the former Part 23 of the NGR, which was replaced by Part 10.

The Commonwealth Minister (being the relevant minister) granted a 15 year no coverage determination for the CRWP Loop on 26 May 2015.

On 18 January 2018, the AER granted a 12 year Category 1 and Category 2 exemption under Part 23 of the NGR for the CRWP Loop. Due to reforms to the NGR, the exemptions transitioned to a Category 1 exemption under Part 10 of the NGR.
