The technology enhances HSER practices by integrating visual data sources, including fixed cameras and robotic systems to analyse imagery and extract actionable insights on safety compliance and risk mitigation.
Danny Turner, SVP Projects, said, “The meticulous planning over the last three months reflects Promethean Energy’s steadfast commitment to doing decommissioning the right way, with safety, environmental stewardship, a technical excellence, and cost efficiency at the forefront. Our structured approach ensures that every stage, from platform preparation to post-plugging verification, delivers long-term integrity and measurable value to our stakeholders.”
The scope of work is organised under five key operational phases:
This milestone underscores the operator’s continued leadership in delivering efficient and technically robust decommissioning programmes across the Gulf.
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.
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.

Helix Energy Solutions Group has reported a strong turnaround in its financial performance for the third quarter of 2025, posting a net income of US$22.1mn.
This marks a significant improvement from the US$2.6mn loss in the previous quarter, though slightly below the US$29.5mn recorded in the same period of 2024.
The company’s Adjusted EBITDA climbed to US$103.7mn, more than double the US$42.4mn achieved in Q2 2025, and higher than the US$87.6mn posted in Q3 2024. Third-quarter revenues also strengthened, reaching US$376.9mn, compared with US$302.3mn in the preceding quarter and US$342.4mn a year earlier.
For the first nine months of 2025, Helix reported net income of US$22.6mn on US$957.3mn in revenue, slightly lower than the US$35.5mn profit on US$1.003bn earned in the same period last year.
Owen Kratz, President and CEO of Helix, said the company’s latest results represent its highest quarterly EBITDA since 2014, demonstrating the business’s growth potential. “The strong Q3 results provide insight into the business’s earnings potential,” he said, noting the achievement came despite downtime on the Q4000 and the Seawell rigs being stacked.
Following the improved performance, Helix has revised its full-year 2025 Adjusted EBITDA guidance upwards to between US$240mn and US$270mn, and now expects free cash flow generation of US$100mn to US$140mn.
Operationally, the company saw robust results across several divisions. The robotics segment benefited from increased trenching and renewable energy operations, while the shallow water division recorded higher levels of activity.
Helix also secured key commercial contracts, including a four-year robotics trenching agreement in the North Sea and a Well Intervention contract in the Gulf of America.
Revenues in the Well Intervention segment grew 23 per cent sequentially, driven by higher utilisation of the Q5000 and Q7000 rigs, while robotics revenues increased 16 per cent thanks to stronger trenching demand. The shallow water abandonment division saw the sharpest rise up 47 per cent due to higher utilisation of the Epic Hedron vessel and improved asset activity.
As part of Phase 1 development, four wells in the Shenandoah field have been ramped up by Beacon Offshore Energy to attain the target rate of 100,000 bopd / 117,000 boepd.
The Shenandoah floating production system (FPS) has proved its top tier operability as it delivered exceptional well productivity, reliability and uptime metrics, while accomplishing the ramp up target within 75 days following first production.
The Shenandoah reserves, located at reservoir depths of approximately 30,000 ft true vertical depth, are being developed utilising industry leading high pressure 20,000 psi technology which Beacon expects to facilitate development of other similarly situated fields in the Inboard Wilcox trend.
The Shenandoah FPS located on Walker Ridge 52 approximately 150 miles off the coast of Louisiana in a water depth of approximately 5,800 feet has a nameplate capacity of 120,000 bopd and 140 mmcfd. The Shenandoah FPS has been designed as a regional host facility that will enable development of additional resources including the Beacon-operated Monument and Shenandoah South discoveries which together with Shenandoah are expected to hold recoverable resources of nearly 600 MMBOE. Beacon is working alongside HEQ Deepwater and Navitas Petroleum to develop the Shenandoah project.
Navigating the pressures of burgeoning decommissioning liabilities of North America and the Government-flagged urgency for immediate action, Petrofac recently initiated the 'Boomerang' project, mobilising a team to take over custody of the field in only a month.
The company's extensive experience and industry connections allow it to equally leverage the local and global supply chain, thus offering a resonable and customised service with the best suited equipment and crews, in a very tight and competitive market. Such measures helped Petrofac deliver the significant Danos decommissioning project in the Gulf of Mexico by collaborating with more than 250 vendors. It saw Petrofac tackling end-to-end decommissioning services, from project management, planning and engineering to procurement, field execution oversight and fast-tracking mobilisation of industry-leading experts.
To achieve cost efficiency that forms the core of Petrofac's approach to decommissioning, the company resorts to new approaches and innovations to match the project scale.
For instance, deploying compact, low-cost crews for pre-decommissioning activities, involving diagnostic and wellhead maintenance work can ensure better planning, permitting and cost estimating.
Other economic ways employed by the company includes well work delegation to groups of 3-6 people, alongside equipment upgradation, crew utilisation and ensuring minimal non-productive time.
“This significant contract recognises our industry-leading decommissioning programme management experience and our unique in-house capability to manage all well and asset decommissioning phases.
“Four decades of global expertise will be applied to the project, complemented by our already strong onshore presence in Texas,” said Iain Murray, President, Americas, Asset Solutions.
