SEA Gas Pipeline System
The PCA and PCI pipelines form a high pressure natural gas transmission pipeline system that transports natural gas from Port Campbell to various offtakes and interconnected pipeline systems in South Australia and Victoria. It incorporates a number of laterals owned and operated by SEA Gas together with associated facilities such as connection point infrastructure and all equipment required to operate the pipeline system.
The Mortlake Pipeline is a high pressure natural gas transmission pipeline that transports gas from Port Campbell to the Mortlake power station in Victoria.
SEA Gas provides pipeline services with market reflective pricing to deliver shippers’ gas, which may be sourced from multiple points, to the required destination.
