Dampier Bunbury Pipeline

What Dampier Bunbury Pipeline does

Dampier Bunbury Pipeline (DBP), a subsidiary of Australian Gas Infrastructure Group (AGIG), operates the Dampier Bunbury Natural Gas Pipeline (DBNGP) — Western Australia's principal gas transmission backbone, spanning approximately 1,539 km of mainline pipe, 1,228 km of looped pipe, and 300 km of laterals between Dampier in the north and Bunbury in the south-west. The asset includes 10 compressor stations with 27 compressor units delivering a designed Firm Full Haul capacity of 845 TJ/day (in excess of one petajoule of energy daily), with 83% of the system duplicated (looped) for redundancy and capacity flexibility. Pipeline integrity is managed through Fusion Bonded Epoxy and 3-layer Trilaminate coating programs and a scheduled intelligent-pig inspection regime on 5- and 10-year cycles.

The pipeline commenced operations in 1984 after construction launched in 1982, was privatized from State Energy Commission (SECWA) ownership in 1998, and was acquired by DBP in 2004, which has since invested approximately $1.7 billion in expansion (Stages 4, 5A, 5B), lifting capacity by 60%. DBP operates as a regulated gas transmission utility, earning revenue through capacity reservation (ship-or-pay) tariffs and throughput fees charged to shippers and gas producers under long-term contracts. Customers are concentrated in Western Australia's mining, resources, manufacturing, and minerals processing industries — with Alcoa named as the original cornerstone customer and North West Shelf Partners as the primary long-term gas supply counterparty.

DBP's customer acquisition is direct enterprise-level: long-dated commercial negotiations with large industrial buyers rather than volume-based marketing. The asset is positioned as the most efficient and economical means of transporting natural gas from the North West Gas Fields to the State's south-west, supplying more than half of WA's primary energy needs. Strategically, DBP sits inside AGIG's broader renewable-gas agenda — including hydrogen parks and a Western Australian feasibility study — which provides optionality for repurposing capacity for hydrogen or biomethane carriage without requiring greenfield pipeline build-out.

Core offering

Dampier Bunbury Pipeline operates a 1,539km regulated high-pressure natural gas transmission pipeline spanning Western Australia from Dampier in the north to Bunbury in the south-west, supported by 10 compressor stations and 27 compressor units. The pipeline transports natural gas from the North West Gas Fields to major mining, resources, and manufacturing customers under long-term ship-or-pay capacity reservation contracts and throughput-based tariffs, delivering over one petajoule of energy daily at a designed capacity of 845 TJ/day.

Product overview

Dampier Bunbury Pipeline (DBP) is a single core infrastructure product — a high-capacity gas transmission pipeline spanning approximately 1,539km of mainline pipe, 1228km of loop pipe, and 300km of lateral pipe across Western Australia. DBP operates 10 compressor station sites with 27 compressor units to deliver natural gas to mining, resources, and manufacturing customers. The company also provides pipeline integrity management services including intelligent pigging and coating maintenance. There are no separate modules, software products, or add-on services — the offering is the pipeline infrastructure and its operational management.

Products and services

• Dampier Bunbury Natural Gas Pipeline (DBNGP) Transmission Services Regulated natural gas transmission services transporting gas from Western Australia's north-west gas fields through a 1,539km mainline pipeline (with 1,228km of looped pipe and 300km of lateral pipe) to industrial customers in the State's south-west. Delivers over one petajoule of energy daily at a designed Firm Full Haul capacity of 845 TJ/day, supported by 10 compressor stations and 27 compressor units, and is offered under long-term ship-or-pay capacity reservation contracts to mining, resources, and manufacturing customers.
• Pipeline Integrity Management Services End-to-end integrity management of the DBNGP pipeline assets, delivered under DBP's formal Asset Management Plan and including Fusion Bonded Epoxy and 3-Layer Trilaminate protective coatings for below-ground pipelines, in-service coating performance monitoring, and scheduled intelligent pigging programs (5 and 10-year cycles) that measure pipeline wall thickness via pig runs between compressor stations to confirm asset integrity and identify areas for investigation or repair.
• Compressor Station Operations and Pressure Management Operation of the DBNGP's 10 compressor station sites containing a total of 27 compressor units that maintain pipeline pressure and flow from Dampier in the north to Bunbury in the south-west of Western Australia. The compressor network underpins the pipeline's designed capacity of 845 TJ/day and is operated in close consultation with shippers to enable intelligent pigging runs and to maintain supply integrity to customers.

• State Energy Commission (SECWA)foundationalStrategic or Co-development Partner · 1 January 1979SECWA was responsible for the pipeline project, commencing engineering design in 1979. It was the foundation contract customer, entering into long-term contracts with North West Shelf Partners to purchase fixed volumes of gas. SECWA operated the pipeline until its privatisation in 1998.
• West Australian Petroleum Pty LtdfoundationalStrategic or Co-development Partner · 1 January 1975Discovery of large offshore reserves of natural gas in the north of WA by West Australian Petroleum Pty Ltd and Woodside Petroleum in 1975 was the beginning of the DBNGP story. This gas discovery led to the conception and construction of the pipeline.
• Woodside PetroleumfoundationalStrategic or Co-development Partner · 1 January 1975Co-discoverer of offshore gas reserves that led to the pipeline development. Woodside Petroleum is a key participant in the North West Shelf gas project.
• North West Shelf PartnerscoreOthersLong-term gas supply contract with North West Shelf Partners to purchase fixed volumes of gas for transportation through the DBNGP to customers.
• AlcoacoreStrategic or Co-development PartnerInitial cornerstone customer for the DBNGP project. Alcoa's support was instrumental in the pipeline's development, providing demand certainty for the project.
