As the decommissioning industry in both on and offshore continues to grow, the rate of change is accelerating. Increasing pressure to address growing regulatory and reporting requirements is transforming decommissioning from successful delivery of on and offshore closures safely and on schedule, to delivering projects with maximum benefits and impact reporting, particularly with environmental and contamination, local communities and stakeholder engagement. It becomes increasingly vital to have a robust strategy in place to tackle the changing landscape. Liberty Industrial will take us through how some recent key learnings have been used to leverage and elevate decommissioning programs, particularly with regards to remote and international experience.

We will explore these learnings from recent case studies that have seen the benefits in applying innovation with technology, recycling, skill development and local engagement strategies.

Circular Seed will delve into the complexities of managing waste from decommissioning assets, with a strong emphasis on the circular economy to reduce environmental impact. We'll present our pioneering resource recovery techniques, developed in-house and operational in Western Australia, focusing on the sustainable reuse and repurposing of materials. Our objective is to showcase the environmental benefits of adopting the reduce, reuse, and recycle mantra in decommissioning activities. By aligning these practices with global sustainability goals, Circular Seed aims to illustrate the vital role that decommissioning projects play in combating resource depletion and climate change, thereby fostering a more sustainable and resilient future.

The geographical advantage of the Gascoyne Gateway Green Port Facility, located in Exmouth, presents a strategic value proposition in the realm of decommissioning offshore facilities. Located in close proximity to numerous offshore structures in need of decommissioning, the port facility will offer a pivotal base of operations for such activities. The accessibility of the port facility can significantly reduce transit times, ensuring cost-effective and efficient mobilisation of decommissioning assets. The Green Port Facility’s dedication to environmental sustainability provides a platform that decommissioning projects can support ecological considerations, minimising the environmental and carbon footprint, in recognition of the impact hydrocarbon industry during production. This facilitates a more sustainable end-of-life cycle for offshore facilities while bolstering regional economic growth through job creation and local industry engagement. The Gascoyne Gateway Green Port Facility emerges as a vital component in the responsible and resource-efficient dismantling of offshore infrastructure, aligning economic pursuits with environmental stewardship.

In the pursuit of safeguarding our environment, the Australian Government has recognised decommissioning as the paramount strategy to mitigate future environmental risks posed by oil and gas infrastructure. However, this process presents a formidable challenge, requiring solutions that transcend traditional methods.

Central to this challenge is the imperative to identify and implement 100% environmentally sustainable approaches. Mere relocation of environmental burdens or creating future liabilities is not acceptable. Instead, the focus is on fostering a circular economy model, where decommissioned assets are repurposed or recycled, minimising emissions and achieving zero landfill.

In this presentation, we delve into groundbreaking solutions that not only address the environmental risks associated with decommissioning but also pave the way for a more sustainable future in the oil and gas industry. From innovative technologies to holistic strategies, we explore avenues that lead to effective, responsible, and environmentally sound decommissioning practices.

This presentation will explore some of the key regulatory landscape and associated legal risks faced by stakeholders in the Australian decommissioning sector. These include the nature and scope of the titleholder's primary responsibility, the implications of effecting the base case of total removal, and the problematic nature of deviations, the expansive scope of trailing liabilities and of "related person", the requisite financial assurance for the risk of marine oil pollution, and the operation of change of control provisions.

These measures are expected to positively influence the behaviour of stakeholders in a practical sense, to lead to greater awareness and to the promotion of standards that are suitable to Australian conditions, which differ from conditions encountered elsewhere. This can be achieved by active and ongoing engagement with stakeholders.

The presentation will also consider possible strategies for mitigation of risks in project execution, and the risk of disputes.

Australia is relatively early in its oil and gas decommissioning journey however some things are clear, globally there is a significant increase in decommissioning activity. Competing regions, adjacent sectors, the availability of resource, and the relative remoteness of the Australian market all contribute towards the challenges the country faces in delivering decommissioning liability safely and efficiently.

We have a responsibility to shift the paradigm in Australia’s oil and gas decommissioning sector from a challenge to an opportunity and identify where we see the potential for demand to outstrip supply. Whether that be around supply, ways of working, contracting models or regulatory frameworks, it is incumbent on us to take what has worked well in more mature regions, and most importantly, what hasn’t worked well to shape Australia’s sector.

The industry can do this by recognising and leveraging global trends, and getting ahead of the curve through integration, outsourcing, single contracts and long term agreements, and much more. Whether driven by necessity from time pressure, a quick shift in regulatory policy, or a significant change in approach to late life and decommissioning, the operator and supply chain will need to push a new way of working for mutual benefit.

The bismuth alloy technology is capable of permanently and eternally shutting-off gas migration in single or multiple casing annuli by forming a V0 rated Metal-to-Metal gas tight seal. For P&A operations the bismuth alloy barrier technology results in a significantly higher level of sustainability compared to the current conventional way of performing P&A operations in oil and gas wells. This requires to be acknowledged in the vision for the future of P&A which will be one of the most emission intense oil and gas activities.

Well decommissioning has a progressive history in Australia - with activity levels exceeding global mature basins, and a pace of execution that eclipses many of the North Sea operations. However, the contracting approach and category management reflects conventional and conservative well construction procurement practices. Join the team to discuss the well decomMISSION, our sectors mission to create sustainable decommissioning that enable well slot reuse, repurposing to decarbonisation.

The decommissioning process of a retired offshore asset demands tactical planning, coordination, and execution, akin to military precision, for guaranteed success. Accurate knowledge of the asset's current condition is critical when making informed decisions. If the intelligence of an asset proves incorrect during execution, the consequences for adapting the strategy on tasks such as decontamination, access point identification, structural load points, lift and cut instructions, can quickly escalate and lead to significant cost overruns.

To mitigate potential risks, many major operators have entrusted the services of Airscope for creating a Reality Capture photogrammetry model of aging assets. The dimensionally accurate Digital Twin model is easily accessible on Airscope's browser-based SaaS platform, 'Visualize™.' This platform facilitates ‘on-site’ remote access, empowering detailed work pack planning and provides technical confidence throughout all stages of decommissioning and removal.

During the last 25 years, KSAT has consolidated solid and reliable experience in Earth Observation services, especially its Near-Real Time (NRT) Oil Spill and Vessel Detection services.

The KSAT Decommissioning service is targeting stakeholders from both contractors and regulators, and the use of satellite data is proven to provide the involved project team with an overview of the area before the activity starts, during the decommissioning activity and finally, area surveillance after completion.

Satellites are the most cost-efficient monitoring tool, compared with aircraft and vessels. The portfolio of satellites from KSAT is unique and currently we deliver surveillance reports for monitoring of oil spills, Methane, vessel detection, water quality in addition to onshore monitoring and mapping.

With industry partners, KSAT has developed technologies that improve safety in project execution and enhanced environmental monitoring for the offshore energy sector and the broader decommissioning industry.

Operational standards and environment requirements are steadily increasing to difficult-to-achieve levels. Limited space, housing and logistics further constrain produced water and decommissioning on space and personnel. Treating contaminants in offshore operations has varying inlet concentrations with increased challenges such as Mercury.

As the amount of well decommissioning in Australia ramps up, the industry will be increasingly facing the challenge of connecting to old weak wellheads. This problem is partly age related, due to accumulated fatigue, corrosion and other related factors, but is exacerbated by the larger, heavier BOP stacks of modern rigs. Other challenges include: unsocketed wellheads, and lack of detail on the wellhead design such as weld data. This presentation explores some of the options available to the industry in addressing this challenge, looking at more accepted options such as tethering, but also alternatives such as an ALARP approach to safety factors used in loading analysis, lightweight BOPs, and opportunities for maximising open water operations.

The North Sea decommissioning domain is dynamic, and our vessel-based team has extensive expertise in this field. Our success is rooted in pioneering abrasive cutting technology and the innovative SEABASS system. SEABASS is a single-trip straddle system that provides next-generation riser-less well decommissioning. It perforates single or multiple casing strings, creates a circulating path for contaminant removal, and places environmentally sound cement plugs. This streamlines operations, enhances safety, and mitigates risks. Our strategic focus includes collaborative partnerships with vessel providers, operators, and third parties, coupled with mobilization efficiencies driven by experience, simulation testing, and adaptation. We excel in interpreting well data, anticipating unforeseen challenges, and optimizing operational scopes to de-risk complex projects. The accolade of the “Decom-Mission Award for Innovation” at the 2023 annual awards underscores the system’s groundbreaking impact.

Positive engagement of stakeholders is not only required by decommissioning regulation, but also is critical in avoiding PR and reputational disasters downstream. Stakeholder engagement often occurs as a ‘necessary evil’ to be executed to tick boxes, but the leading thinkers in oil and gas decommissioning are seeing the huge opportunity of turning stakeholder engagement into an asset in support of the decision process. Positive stakeholder engagement starts right in the design of the decommissioning decision process – by creating a collaborative approach to decision making built on best-practice decision science. Paul will share his 20 years' experience designing and facilitating collaborative, multi-stakeholder decision processes with high levels of stakeholder participation and speak first-hand to real world examples from decommissioning decision making. Paul will draw out some key, fundamental principles which make the difference.
