Port Campbell to Adelaide Pipeline

Type of project: Gas Infrastructure

Client: SEA Gas
Location: Minerva (VIC) to Port Adelaide (SA), Australia
Completed in: 2004

The SEA Gas Pipeline was a major infrastructure project designed to enhance energy security for South Australia by providing a vital alternative to the state’s traditional gas supply. Spanning 687 kilometres from Port Campbell in southwest Victoria to Pelican Point in South Australia, the pipeline was developed to transport natural gas from new offshore Victorian fields to meet growing demand and diversify supply sources.

Spie Capag-Lucas, a joint venture between Spie Capag and AJ Lucas, was selected as the EPC contractor for the project. The team was responsible for the full scope of delivery – including detailed engineering, procurement, construction, testing, and commissioning, while also managing complex stakeholder engagement across two states, hundreds of landowners, and numerous local authorities.

The pipeline features a combination of twin 14-inch diameter pipes and single 18-inch diameter pipe, supported by two compressor stations located at Coomandook (SA) and Miakite (VIC). Its successful and timely delivery played a critical role in ensuring uninterrupted gas supply to South Australia during a period of transition in the region’s energy landscape.
