Decommissioning
Energy and marine consultancy ABL is supporting Esso Australia Resources as it gears up for the offshore removal campaign of up to 12 platforms on the Gippsland Decommissioning Campaign Project.
This is Australia’s largest offshore decommissioning campaign.
Esso is the operator of the assets in the Bass Strait that are part of the Gippsland Basin Joint Venture. In total, assets comprise of approximately 400 wells, six subsea facilities, and more than 800 kilometres of subsea pipelines, and 19 platforms. After delivering energy to Australia for over 50 years, Esso is planning to undertake the first Bass Strait decommissioning campaign.
With approximately 60,000 tonnes of offshore structures to be removed and a target to recycle over 95 percent of materials, the project represents a major milestone for Australia’s decommissioning and circular economy ambitions.
ABL’s operations in Australia were commissioned by Esso to provide marine warranty survey (MWS) services to support in the safe and efficient delivery of the first phase of the decommissioning campaign.
Preparations for the campaign are well advanced, with the offshore lifting campaign to remove up to 12 platforms scheduled to commence in 2027 using Allseas’s Pioneering Spirit.
In preparation, ABL is conducting suitability surveys to validate the proposed marine spread, and technical review and approval of decommissioning documentation. Its scope of work will include on-site attendance at all warranted offshore operations to ensure activities are executed safely and in line with approved procedures.
