Two substantial platforms in the Gulf of America were subjected to comprehensive full-cycle offshore decommissioning campaigns by MC Offshore Petroleum, which also advanced environmental stewardship.
A multi-asset operation, the campaign involved the retirement of the Jolliet Tension Leg Well Platform (TLWP) in Green Canyon Block 184 and the fixed production infrastructure at Marquette comprising a production platform, GC52A, and a processing platform, GC52CPP, in Green Canyon Block 52. These will be further converted into an artificial reef in Green Canyon Block 52.
When installed as the first TLWP in the Gulf of America, Jolliet came to be known as the world's deepest floating production unit at the time of installation. The current campaign honours the platform's legacy while establishing a model for the next generation of offshore decommissioning excellence.
Right from the planning stage in 2022, MCOP has followed a strategy to execute the removals ahead of the peak months of hurricane season. The final decision to begin decommissioning operation was made in the first quarter of 2024. Decommissioning operations, along with the plug and abandonment of all wells on GC 52-A (Marquette) and GC 184 (Jolliet), were set to begin with an execution team in place by the second quarter of 2024.
With the well P&A work underway, pipeline abandonment operations begun as three pipelines were flushed and abandoned. The project team also abandoned another 24-mile pipeline belonging to a midstream operator that originated at GC52.
The decommissioning of the Jolliet TLWP and removal of GC52A and GCS2CPP was made possible with high-level engineering work. Disconnecting the TLWP tendons from the template, ballasting the JOLLIET TLWP during tendon removals and towing the platform to Port Aransas were backed by extensive planning.
The Institute for Energy Economics and Financial Analysis (IEEFA) has published its responses to the Victorian Legislative Council Environment and Planning Committee and its inquiry into the decommissioning of oil and gas infrastructure.
IEEFA is an independent energy finance think tank that examines issues related to energy markets, trends and policies.
The Institute’s mission is to accelerate the transition to a diverse, sustainable and profitable energy economy.
In a statement published on its website, IEEFA noted that Victoria is in a “unique position” to establish a decommissioning industry, given the state has some of the oldest oil and gas extraction infrastructure in Australia “and therefore has a greater proportion of its property and equipment ready for decommissioning.”
It also called on the Victorian government to ensure decommissioning work is undertaken in an orderly and transparent manner.
“This will help to keep cost downs and provide opportunities for the state’s oil and gas workforce and contractors to move into the next phase of oil and gas lifecycle, decommissioning.
Victoria’s decommissioning asset profile includes 22 platforms, over 2,000 km of pipelines and umbilicals, as well as around 460 wells to be plugged and abandoned, according to the National Offshore Petroleum Safety and Environmental Management Authority (Nopsema).
The infrastructure earmarked for decommissioning offshore Victoria is owned and operated by a handful of companies.
Historically, the largest oil and gas producing complex is the Gippsland Basin Joint Venture (GBJV), also known as the Bass Strait project. This year, Woodside took over as operator of the venture from ExxonMobil, which had operated the project since 1969.
Other companies with decommissioning liabilities offshore Victoria include Beach Energy and Amplitude Energy.

In an article on the ASCO website, John Davidson, Operations Manager – Environmental Services, ASCO discusses how the UK’s experience of building a system to deal with Naturally Occurring Radioactive Material (NORM) can benefit Australia.
Davidson points out that as Australia faces a massive decommissioning wave, dealing with NORM will be one of the challenges it will need to address. This residue, which builds up in pipework, tanks and separators over years of oil and gas production, carries radiological risks and requires expert handling, treatment and disposal.
In the UK, the oil and gas sector has been dealing with NORM for decades, although the early years were challenging, he notes. “But through trial and error, the UK built a system that now works,” he says.
“NORM processing was centralised. Long-distance, highly regulated transport systems were developed. Experienced specialists were embedded into local teams. Most importantly, collaboration gradually replaced competition. Today, the UK has one of the most mature decommissioning supply chains in the world.”
Australia has a chance to avoiding years of inefficiency and unnecessary cost by learning lessons from the UK experience, he suggests. ASCO, which has built and operated one of the world’s most advanced NORM facilities in the North Sea, can now transfer that knowledge directly into Australia.
He goes on to suggest that a logistics strategy to deal with the long distances of offshore assets from disposal sites needs to be put in place; the expertise of experienced specialists should be leveraged at an early stage; and collaboration between companies should be encouraged, with shared infrastructure, expertise and logistics creating efficiencies and helping to address gaps in local capabilities.
On the questions of regulation, he notes that UK authorities engaged closely with industry to co-develop standards and best practice. “The UK’s lesson is clear: proactive engagement builds trust, accelerates approvals and avoids gridlock.”
“If Australia can absorb the lessons above now, rather than repeat the UK’s early missteps, it has the opportunity to build one of the world’s most resilient and effective decommissioning supply chains,” he concludes.
In a strategic move to strengthen the energy export network of the US Gulf of Mexico, Shell and Chevron have joined forces once again through their Amberjack Pipeline Company joint venture.
The partnership has awarded offshore contractor Allseas a major contract to install the Rome Pipeline, a 150-km, 24-inch trunk line designed to boost oil transport capacity from Shell’s Green Canyon 19 platform to the Louisiana coast.
This vital new link will expand Shell’s extensive Gulf of America pipeline system, enhancing export efficiency and operational flexibility across the region’s offshore network. The project underscores Shell and Chevron’s ongoing commitment to modernising and optimising oil transport infrastructure in one of the world’s most productive offshore basins.
Installation will be executed in two main phases. The nearshore section, scheduled for 2027, will be handled by Allseas’ automatically positioned anchor barge Sandpiper. Following that, the dynamically positioned pipelay vessel Solitaire—one of the most advanced ships of its kind will take on the deepwater installation in 2028. Together, these operations will form a critical artery within the Gulf’s subsea network, ensuring smooth and secure flow of hydrocarbons to shore.
The Rome Pipeline builds on the long-standing collaboration between Shell, Chevron, and Allseas, following the successful completion of previous ventures such as the Amberjack Debottleneck Project in 2016.
With an impressive record of more than 8,000 km of subsea pipelines safely installed in the US Gulf, Allseas continues to play a key role in shaping the region’s energy infrastructure. This new project not only reinforces its technical excellence but also represents a significant milestone in sustaining the Gulf’s vital oil and gas exports for years to come.

The forward look for well services and interventions across the Asia Pacific market, and for other industry providers, bodes well as spending levels accelerate across the region.
In the latest insight paper by Westwood, offshore investment is expected to remain resilient despite a turbulent year for global oil markets.
Between 2025 and 2029, offshore engineering, procurement, construction and installation investment is projected to reach US$310bn globally, with APAC accounting for 27% of this spend, it notes.
Southeast Asia alone is set to award US$37bn in new offshore contracts, led by deepwater gas projects in Indonesia, and emerging carbon capture and storage (CCS) initiatives in Malaysia.
Thailand is also embarking on its maiden CCS scheme.
“Oil and gas companies – including regional NOCs – continue to prioritise decarbonisation, though the approach is evolving toward more disciplined oil and gas investment and cost efficiency,” Westwood notes in the paper.
“This shift is expected to drive down industry costs, even as supply chain margins remain under pressure.”
These macro trends are influencing not just oil and gas, but also the region’s growing offshore wind sector, it adds.
This could mean a weakening in rates for the offshore marine fleet that services the region’s oil and gas industry.
There are currently 84 active platform supply vessels and 449 anchor handling tug/supply vessels in the Asia Pacific region, operated by key incumbents such as Wintermar, HADUCO and Nam Cheong.
Dayrates for offshore support vessels have softened from recent record highs yet continue to exceed historical averages, according to Westwood, sustained by firm utilisation levels amid tightening supply as units are redeployed out of the region.
In its concluding remarks, Westwood notes that the Asia Pacific offshore market is navigating both challenges and opportunities as 2025 draws to a close.
From ageing fleets and cost pressures to the promise of offshore wind and deepwater gas, the region is poised to play a key role in the global energy transition, it adds.
As Asia Pacific continues to evolve, Westwood notes that staying informed and engaged will be key for all stakeholders across the energy value chain.
“As frameworks evolve and investment flows shift, collaboration between operators, service providers and governments will be essential to unlocking sustainable growth,” it states.
“Innovation in technology, financing and project execution will define the next chapter of offshore energy.”
