Energy and marine consultancy firm ABL will participate in the preparation of the largest offshore decommissioning campaign ever undertaken in Australia. The company will support Esso Australia Resources Pty Ltd in the execution of the Gippsland Decommissioning Campaign Project No. 1, an operation that involves the removal of up to 12 offshore platforms in the Bass Strait.
The project marks a new era for Australia’s offshore industry after more than five decades of energy production in the region. Assets operated by Esso within the Gippsland Basin Joint Venture include approximately 400 wells, 19 platforms, six subsea facilities, and over 800 kilometers of subsea pipelines.
A large-scale offshore operation
With nearly 60,000 tons of marine structures slated for removal, the campaign represents one of the biggest logistical and technical challenges for the Australian energy sector. The project also aims to recycle more than 95% of the removed materials, aligning with the sustainability and circular economy goals promoted in the offshore industry.
The first phase of the program involves offshore lifting operations starting in 2027 using Allseas’ PIONEERING SPIRIT vessel, recognized for its ability to remove large platforms in offshore decommissioning projects.
ABL will oversee critical maritime operations
As part of its involvement, ABL will provide Marine Assurance Inspection (MWS) services to support the safe and efficient execution of offshore activities. The company will conduct marine suitability assessments, technical reviews, and validation of decommissioning-related documentation.
In addition, the scope of work includes technical presence in maritime operations that require direct supervision to verify compliance with approved procedures and minimize operational risks.
Adam Solomons, East Coast Manager at ABL Australia, highlighted that the complexity of the project requires multidisciplinary expertise due to the relocation and removal of offshore assets up to 50 years old.
Australia accelerates its decommissioning plans
The Gippsland project is shaping up to be a benchmark for future offshore decommissioning campaigns in Australia. The country’s energy industry is moving towards a stage where multiple oil and gas assets will reach the end of their useful life over the next few decades.
In this context, companies specializing in marine engineering, inspection and offshore logistics will play a key role in the transition to more sustainable operating models.
ABL has over 40 years of experience in oil, gas, and offshore wind decommissioning projects. The company operates in Australia from offices in Perth, Sydney, and Brisbane, and maintains a presence in Melbourne through its affiliated company, OWC.
