SEAGas pipeline, Natural gas pipeline in South Australia and Victoria, Australia
The SEAGas pipeline is a natural gas distribution system extending from Port Campbell in southwest Victoria to Pelican Point in South Australia with multiple branch lines. The network uses varying pipe diameters to move gas across different regions and elevation changes.
Construction began in 2002 near Tintinara and the pipeline commenced operations in 2004 to establish gas supply connections between two states. The project represented an important infrastructure development linking multiple energy suppliers and consumers.
The pipeline represents a milestone in Australian energy infrastructure, connecting multiple energy suppliers and consumers across two different states.
Two compressor stations in South Australia and Victoria maintain pressure throughout the system and ensure continuous gas flow. Most of the pipeline route runs across farmland and can be difficult to access directly, but markers along roads sometimes indicate its presence.
The system uses two different pipe diameters across its length, with some sections using twin smaller pipes and others using a single larger pipe. This design choice optimizes flow capacity based on regional demand and geography.
