Perth-based Monadelphous has extended a strong run of contract wins, securing about $110 million in new work across offshore gas, decommissioning and grid-scale storage, a day after announcing major projects for BHP and Rio Tinto in the Pilbara.
The engineering contractor has been awarded a four-year maintenance services contract with BW Offshore for the BW Opal floating production, storage and offloading vessel (FPSO), located about 300km north-north-west of Darwin. Work is due to start in the first quarter of this year.
Monadelphous MD Zoran Bebic says the contractor has built a global offshore résumé, but its publicly disclosed oil and gas work remains heavily concentrated in Australian waters, spanning long-running maintenance, brownfields and decommissioning roles across the Browse, Bonaparte and Carnarvon basins and the Timor Sea.
"Over the past decade, we have continued to strengthen our reputation for the consistent and reliable delivery of offshore maintenance services to our customers, and are proud to work on some of the most significant energy facilities in the world," Bebic said, adding that the company was "pleased to be trusted by industry leaders for repeat work, and to be recognised for the depth of our expertise and capabilities across the asset life cycle."
BW Opal is the production hub for the Barossa LNG development, a joint venture led by Santos, SK E&S and JERA. The project is nearing the final stages of commissioning, with first gas targeted for the September quarter of 2025.
Barossa represents one of the largest gas investments currently underway in Australia's north, with several billion dollars already committed to offshore production, subsea infrastructure and export pipelines feeding into Darwin. Once on stream, the BW Opal facility will anchor production from the field and underpin LNG exports into Asian markets over the coming decade.
Monadelphous has also secured a contract with Santos in Papua New Guinea to demolish and dispose of the Hegigio Pipeline Bridge, a 500-metre suspended wire structure spanning the Hegigio Gorge in the Southern Highlands.
The bridge, originally built by Oil Search (now merged into Santos) to carry oil pipelines serving the South-East Mananda field, was severely damaged in the 2018 earthquake and has since been earmarked for removal as part of broader decommissioning works. Monadelphous expects demolition activities to be completed in the second half of 2026.
Rounding out the latest awards, Zenviron — Monadelphous' renewable energy joint venture — has won a contract from Flow Power to deliver the Bennetts Creek battery energy storage system in Victoria's Latrobe Valley.
The 100MW/223MWh project will include balance-of-plant design, construction, installation and commissioning, with completion slated for late 2027. The battery is intended to support grid reliability in a region undergoing rapid transition as coal-fired generation exits the system.
The latest wins reinforce Monadelphous' diversified exposure across traditional resources, offshore energy, and fast-growing renewable infrastructure, at a time when major producers and utilities continue to increase spending on maintenance, life-extension, and energy transition assets.
