The proponent proposes to construct and operate a number of looping sections adjacent (and connected) to the existing underground gas transmission pipeline within the DBNGP corridor. There are nine separate looping sections proposed from CS 1 south of Karratha, to CS 9, north of Gingin.
Looping is a process of duplicating an existing pipeline between compressor stations for a certain distance. Once the specified distance is reached, it then ties back to the parallel pipeline. This design results in an increase in the gas flow rate and an increase in the volume of gas stored within the pipeline infrastructure.
