The number of offshore assets reaching their end of life, globally, is rising, meaning decommissioning projects are a real eventuality for many operators.
Decommissioning is an inherently hazardous exercise, one that requires meticulous planning, experienced people and an extremely defined skill-set, if it is to be executed safely.
Whilst decommissioning is an expensive business, costs have been declining in recent years due to increased innovation, better cooperation throughout the supply chain and the development of first-class skills and capabilities.
In this article, Richard Lind, Operations Manager for Ashtead Technology’s Mechanical Solutions service line discusses the many challenges facing the sector and how Ashtead Technology can help Operators make decommissioning safer and more cost effective, whilst reducing environmental impact.
“Ashtead Technology are international experts in the provision of offshore decommissioning services for the energy sector. With one of the largest fleets of decommissioning tools and systems in the market, we specialise in ROV tooling, control and monitoring solutions, structure monitoring services, cutting systems and seabed dredging solutions.
“We offer a comprehensive service capability for the cutting and removal of oil & gas and renewable energy infrastructure, with a proven track record in field clearance and structure & pipeline cutting and recovery. Specifically for the renewables market, we provide a suite of services for the decommissioning of met masts, monopiles, tri-pile foundation structures and export cables.
“The continued ambition to reduce decommissioning expenditure is a challenge for the whole supply chain and our aim is to provide customers with the most reliable, efficient and predictable end of life solution, delivered at the lowest cost with no compromise on best-in-class HSE performance."
“Innovation in decommissioning through continued investment in research, development and deployment of technology will maintain and enhance supply chain capability.
“In our relentless pursuit of excellence, we continue to invest in our equipment to ensure we remain at the forefront of what we do. This commitment to innovation and continuous improvement has led to recent enhancements to our subsea cutting solutions portfolio in order to solve our customers’ operational challenges.
“Our recent acquisition of WeSubsea has also bolstered our decommissioning capability, complementing our extensive range of proprietary and third party dredging, cutting and ROV tooling solutions and services.
“Furthermore, we invested in a new technology and service facility based in Aberdeenshire, UK, last year enabling us to fully integrate our service offering and provide a more efficient and streamlined service for our customers. The new facility has doubled the capacity of our previous site to accommodate our growing fleet of equipment and enabled the development of more bespoke technologies to support our customers’ unique project requirements."
“Since our acquisition of UCS in 2019, Ashtead Technology’s ability to bring a decommissioning capability to international customers has significantly increased.
“Drawing on a tried and tested project management model which combines our centre of excellence expertise in the UK with our bolstered international operational capability, we have recently executed multiple successful projects in the Middle East, Asia and West Africa. Furthermore, we have laid the foundations for delivering further complex, multi-service decommissioning projects across these regions, as demand requires."
“Decommissioning is an inherent part of the energy transition agenda with new ways of repurposing and reusing infrastructure being explored. As a proactive participant in the energy transition, Ashtead Technology continues to work with industry partners and the supply chain to support the development of new technology and methodologies to improve efficiency and reduce cost and safety risk in an environmentally responsible manner.”
