sustain:able presenting at SPE Symposium in Perth

CODA Partner sustain:able will be presenting at the SPE Symposium: Asia Pacific Decommissioning and Well P&A, taking place in Perth Australia, 11–12 November, 2025

Their paper, titled “Optimising Decommissioning Strategies: A Case Study on Emissions and Cost Reduction in Offshore Operations” presents a comparative assessment of full infrastructure removal, partial removal, and leave-in-situ scenarios, focusing on emissions and costs.

The study demonstrates how emissions forecasting tools can be applied to offshore decommissioning to identify high-impact activities, optimise vessel and power use, and highlight opportunities for cost and emissions savings. Using a North Sea case study, the analysis compares scenarios ranging from full infrastructure removal to partial removal and leave-in-situ options, showing that lower-emission strategies can often align with lower overall costs.

By integrating emissions into decommissioning planning, operators can make more informed decisions, reduce carbon liabilities, and strengthen ESG performance. These insights are highly relevant to Australia as the industry prepares for a wave of decommissioning projects, with regulators and stakeholders increasingly expecting emissions-informed strategies alongside cost efficiency and safe execution.

Decom Engineering appoints Nick McNally as Managing Director

Decom Engineering has announced the appointment of Nick McNally as Managing Director, marking a new chapter in the company’s growth as it accelerates international expansion and technological innovation in the decommissioning sector.

His appointment reflects Decom’s strategic focus on scaling operations, expanding into new markets, and strengthening its position as a leading provider of patented cutting technologies to the global energy industry.

Nick, who has served as Decom’s Commercial Director since 2019, said: “This is an exciting new stage for Decom as the business evolves from a highly respected niche engineering firm into a globally recognised technology partner.

“With new markets opening up and recent contract wins in Australia, Brazil and the Gulf of Mexico, the opportunities ahead are considerable and my focus will be on building the infrastructure, capability and culture to meet that growth head-on.”

Under Nick’s leadership, Decom has succeeded in rolling out a new ultra-light Chopsaw with improved cutting performance, which has seen the C1-16UL deployed across complex subsea projects in challenging offshore environments, and the company has been buoyed by recent project wins in Australia, South America and Europe.

Under his direction, the company has already consolidated operations in Aberdeen, closed its Northern Ireland facility, and restructured its internal systems and roles as Decom sharpens its focus on strategic delivery and long-term value.

The company is actively progressing ISO certification alongside additional IP coverage and is engaged with the Fit for Offshore Renewables programme, enabling greater access to clean energy markets and expanding opportunities in offshore wind.

Nick added: “With international demand growing and increasing interest in our cutting technology, we’re focused on scaling responsibly, strengthening our systems, investing in our people and remaining agile, which enables us to move into new markets such as offshore wind and onshore decommissioning.”

Mike Irvine, Partner at Cordovan Capital, Decom’s lead investor, said: “Nick brings a focused leadership style and clear understanding of the technical and operational demands of our business and will lead the company into this next phase, ensuring we remain innovative, responsive, and aligned with the evolving needs of the global energy industry.”

Decom is investing in talent and plans to expand its workforce from 16 to over 25 staff within the next 18 months, with new roles across engineering, operations, and business development. Demonstration events in the United States are planned for later this year as the company evaluates potential partnerships and future growth in North America.
