As offshore energy infrastructure expands into increasingly demanding environments, safeguarding the integrity of underwater assets has become a paramount priority for the sector

Rising to this challenge, the underwater technology specialist Sonardyne has formally signed a Memorandum of Understanding (MoU) with AMOG, an international advanced engineering company. Together, they are set to provide a complete subsea asset monitoring service tailored directly to the needs of offshore energy infrastructure operators.

This strategic alliance seamlessly integrates Sonardyne’s trusted underwater positioning, communication, and monitoring technologies with the industry-leading engineering assessment expertise of AMOG. By harnessing their combined capabilities, the partnership aims to unlock vital insights into asset health, substantially reduce costly operational downtime, and enable the safe life extension of critical underwater architecture. Crucially, this comprehensive monitoring approach will support a wide spectrum of subsea installations, encompassing floating offshore wind platforms and traditional oil and gas moorings, alongside essential pipelines and risers.

Dr Hayden Marcollo, a globally recognised specialist in moorings and vortex-induced vibration engineering and analysis, serves as a director at AMOG. Highlighting the transformative potential of the collaboration, he says: “Combining high‑quality subsea data, processed at source on Observer, with advanced engineering assessments, will provide asset owners with more actionable, near-real-time insight into the condition and behaviour of critical subsea infrastructure through a single solution.”

The implications for infrastructure management are profound. Providing a unified approach to complex engineering challenges allows for a proactive rather than reactive operational strategy. As Dr Marcollo further elaborates regarding the commercial benefits: “For operators, this could support earlier detection of anomalies, improved understanding of loads and motions, and more informed decisions around inspection, maintenance and integrity management, as well as asset longevity, in one end-to-end solution.”

The practical application of this partnership is already well underway. Demonstrating the system's immediate relevance to the rapidly expanding renewable energy market, Sonardyne and AMOG are actively collaborating on a near-real-time mooring monitoring system tailored for a European floating offshore wind project.

Frank Rose, business development manager at Sonardyne, outlined the broader vision for the joint initiative. He notes: “By integrating on-demand and long‑term monitoring data from subsea environments with engineering models and analytics, there’s an opportunity to provide a more complete picture of asset performance—whether supporting day‑to‑day operations, integrity assurance or life‑extension strategies.”

This MoU represents a forward-thinking approach to subsea infrastructure management that promises to enhance operational excellence. “By working alongside AMOG, we’re exploring how data and engineering assessments can come together to give operators greater confidence in the way their subsea assets are performing, today and over the long term," Rose adds

Operators need to optimise all drilling processes, including waste management. (Image source: Shutterstock)

As Gulf drilling activity scales, operators are rethinking waste management, says Pierre-Marie Hinden, UAE general manager, TWMA

In the pursuit of expanding oil and gas production across the Gulf, the question increasingly front of mind for many operators is how much more output can be achieved by improving operational efficiency, rather than simply adding more drilling activity.

That question is coming into sharper focus now as the UAE races toward expanding production capacity. ADNOC is leading the charge, accelerating toward its goal of reaching 5 million barrels per day production capacity by 2027 and potentially beyond if needed. And the UAE is not alone as Saudi Arabia continues to ramp up major offshore and unconventional gas developments, while operators across the wider region are expanding drilling campaigns with goals to increase operational capacity.

As Gulf states recover and aggressively rebuild from impacts of the conflict on energy assets, this momentum is expected to continue well through 2027 and beyond. This in turn is driving operators to look more closely at their operations to find efficiencies and recover value. Every operational decision is under increased pressure to maximise performance while minimising cost and, as a result, leading operators are beginning to challenge established practices and examine how every aspect of operations can be adjusted to improve performance.

That includes areas such as drilling waste management, an essential but often overlooked part of drilling operations, which if optimised, can unlock major cost, efficiency, safety and sustainability benefits.

Is traditional drilling waste management still fit for purpose?

Offshore, a typical approach to tackling drilling waste is skip and ship. Here, waste is collected offshore, loaded into skips, transported by vessel to shore and then processed and disposed of on land. It remains a familiar and compliant approach, but one that can also introduce operational complexity, logistical dependency, high emissions and significant hidden costs.

An alternative method is at-source treatment which in a lot of ways, substantially outperforms traditional approaches including across safety, cost, environmental and overall operational efficiency. Rather than transporting waste back onshore, thermal treatment technologies such as the RotoMill allow drill cuttings, slops and sludges to be processed directly at the wellsite. That means fewer vessel movements, fewer lifting operations and significantly reduced logistics requirements. At the same time, valuable base fluids can be recovered from drill cuttings and reused onsite.

To put this into perspective, since 2014, in collaboration with a major operator in the UAE, TWMA’s RotoMill has processed more than 600,000 tonnes of drilling waste, accumulated legacy waste and slop at source. Working with the operator across multiple fields has eliminated more than 70,000 km of transport, reducing carbon emissions by 50%, as well as significantly reducing handling and logistics requirements. Combined with the recovery of approximately US$78mn worth of base fluid for reuse, the total savings are in excess of US$200 mn.

As production ambitions and drilling activity continue to scale across the Gulf, but so do does attention on cost, efficiency and sustainability, case studies like this show what can be achieved by optimising every part of the operation.

What is the real cost of offshore operations?

While operators are increasingly taking a total cost of ownership (TCO) approach across the well lifecycle, there can still be a tendency to focus on upfront costs. But the reality is, what may appear a lower-cost solution on face value, can create wider operational inefficiencies and spend elsewhere.

Traditional skip and ship approaches, for example, may reduce costs at the rig site, but they can also increase vessel demand, fuel consumption and handling requirements and disposal costs. Predicting those knock-on effects is not always easy, and this is where specialist drilling waste management expertise, when brought into projects early, can help operators gain a clearer view of the full operational picture and what tailored solution works for their needs. That includes navigating relevant regulatory requirements, as well as understanding that offshore processing solutions can deliver savings of up to 60% compared to traditional skip and ship methods, or that for a typical 60-day operation, total costs for skip and ship can reach around US$1.24mn, compared to approximately US$510,000 for offshore processing.

Looking ahead, the ambitions of the region, as they always have been, are significant, and we see that through key operators’ production ambitions, as just one example. But scale and expansion is really only one part of the picture. Without doubling down on optimisation of all drilling processes, efficiency, cost and sustainability gains will be left on the table at a time when there is no room for anything but profitable growth.

The new system recovers gas that was previously wasted.

As operators increasingly turn to the latest technologies to achieve their emissions reduction objectives, a leading Omani oil producer used advanced automation to cut site emissions, working with partners Multivista and Flaroman – a division of Majees Technical Services

One of the largest oil and gas producers in Oman operates facilities that extract around 66,000 barrels of oil per day. Alongside its production capabilities, the company is committed to reducing carbon and other emissions and supporting Oman in meeting its obligations under the Paris Agreement.

The producer needed to improve the efficiency and cost effectiveness of gas flaring at its Khamilah oil field, while also reducing greenhouse gas emissions and other byproducts associated with the process. A key objective was to recover more gas that would otherwise be wasted, enabling it to be cleaned and reused for power generation.

At the same time, the company sought to enhance the safety and resilience of its operations. Any new system for gas recovery and flaring needed to operate with a high degree of precision and control, ensuring reliability in what is an extreme and hazardous environment.

The solution

To address these requirements, the producer partnered with Multivista Oman and Flaroman, specialists in industrial systems and flare control equipment. Together, they designed and installed an advanced flow regulating and flare control system.

The solution incorporated an automated design for zero flaring and flare gas recovery, supported by a redundant control system based on Allen Bradley ControlLogix. Integrated between controllers and I O modules, this system delivered high levels of precision, performance and reliability.

The project also included advanced data collection and reporting systems, alongside integrated safety systems. These features improved transparency, minimised operational risk and strengthened overall system resilience while enhancing performance across gas flow and flare control processes.

With the new system in place, recovered gas that was previously wasted can now be delivered to the national gas pipeline, supporting energy supply for both industry and consumers.

Enhanced data collection and reporting provide greater visibility and control, enabling operators to respond quickly to alarms and changing conditions. This improves both operational efficiency and safety.

The system has also improved emissions handling, reducing greenhouse gases and other unwanted byproducts released into the atmosphere. This supports environmental goals and contributes to Oman’s wider climate commitments.

In addition, precision multi discipline control has optimised the productivity of key processes, improved combustion system performance and enhanced flare operations, including smokeless flaring.

Overall, the solution has increased reliability, strengthened safety and delivered more efficient, controlled operations.
