What Decom Engineering does

Decom Engineering Ltd is a UK-headquartered specialist engineering firm founded in 2011 that designs, fabricates, and operates a proprietary range of subsea cutting tools and integrated cutting-lifting systems for the global offshore energy sector. Its core offering is the patented C1 Chopsaw range, built around a linear-drive cutting architecture that feeds the blade directly into the structure being cut, supported by tungsten carbide tipped (TCT) blades, modular drive arrangements, adaptable clamping, and ultra-light / neutrally buoyant variants for ROV deployment in water depths up to 3,000 metres; the product family spans from the compact C1-10 to the 46-inch-capacity C1-46, complemented by the TRACS-16 Twin Recovery & Cutting System, the Tracksaw for confined-space cutting, and Chain Link Retaining Clamps.

The company monetises primarily through project-based equipment rental with embedded technical services — including offshore technicians, project management, and 24/7 operational support — supplemented by bespoke engineering engagements and turnkey decommissioning solutions delivered with partners such as Unique Group. Engagements range from short campaigns (the £1.5 million, 120-day Western Australia flowline campaign in 2026) to multi-year rentals (2-3 year arrangements with CBO Group for Petrobras operations in Brazil), with pricing quoted per project rather than published. Customers are exclusively enterprise-scale offshore operators and tier-one subsea contractors including Shell, Chevron, TotalEnergies, Woodside, Petrobras, Repsol, Subsea 7, TechnipFMC, Allseas, and DeepOcean, served from operational bases in Aberdeen, Stavanger, Dubai, Kuala Lumpur, Perth, Houma, Macaé, Bangkok, Lagos, and St. John's. Decom is privately held, backed by Cordovan Capital, and has recently expanded leadership (Nick McNally as MD from August 2025, Keith McDermott as Chairman from May 2026) and US patent protection (April 2026) to support continued international scaling.

Core offering

Decom Engineering designs, manufactures, rents, and operates proprietary subsea cutting tools and integrated cut-and-lift systems for the global offshore energy sector. Its core product is the patented C1 Chopsaw range of linear-drive cutting tools (C1-10 through C1-46) used to perform precision cold-cuts on pipelines, conductors, mooring chains, umbilicals, and flexible risers during decommissioning, installation, and IRM campaigns, complemented by the TRACS-16 cut-and-recovery system, the Tracksaw precision linear cutter, and Chain Link Retaining Clamps. The company supplies these tools both as rental assets with offshore technicians and as turnkey project-based cutting services.

Product overview

Decom Engineering offers a suite of subsea cutting tools centered on its patented C1 Chopsaw range. The portfolio spans from compact models (C1-10, C1-12) to ultra-large capacity (C1-46) chomsaws, plus the TRACS-16 integrated cutting and lifting system, Tracksaw for precision linear cutting, and Chain Link Retaining Clamps for mooring operations. The tools perform precision cold-cuts on pipelines, conductors, mooring chains, umbilicals, and flexible risers in demanding offshore environments.

Emerging players

• Brokk: Brokk manufactures remote-controlled demolition robots and underwater cutting attachments used in confined-space and subsea demolition, providing partial overlap with Decom's Tracksaw and bespoke cutting solutions.

Broad incumbents

• TechnipFMC: TechnipFMC is a large subsea and surface engineering contractor with integrated project execution capability; it procures Decom's tools (Stybarrow decommissioning) while also offering broader competing decommissioning services.
• Subsea 7: Subsea 7 is a global subsea engineering, construction and services contractor with in-house cutting tooling capability; it is a Decom customer (Shenandoah mooring chain) but also a potential in-house competitor for large offshore campaigns.
• Atlas Copco (Epiroc): Atlas Copco is a broad industrial tools and demolition equipment manufacturer with hydraulic and mechanical cutting product lines that compete with Decom in onshore and topside cutting applications adjacent to subsea.

Direct peers

• Versabar: Versabar designs and operates proprietary subsea cutting, lifting and decommissioning tools used on offshore platforms and pipelines, making it one of the closest direct competitors to Decom's C1 Chopsaw and TRACS-16 portfolio.
• Intermoor (Acteon Group): Intermoor provides mooring installation and decommissioning services and is both a Decom customer (pipeline and conductor projects) and a competitor in mooring chain severance campaigns.
• Helix Energy Solutions Group: Helix Well Ops is a major subsea decommissioning contractor offering integrated cutting, intervention and abandonment services, competing with Decom for major operator decommissioning campaigns.
• James Fisher Decom (James Fisher & Sons): James Fisher Decom provides subsea decommissioning and IRM services globally and is a Decom customer (Thailand pipeline cut and lift project), but also operates competing cutting spreads in adjacent offshore basins.
• Claxton (Acteon Group): Claxton, now part of Acteon, provides subsea cutting and decommissioning services to the offshore oil and gas sector, including conductor and pile cutting, directly overlapping Decom's mechanical cutting offering for decommissioning projects.
• Well-Safe Solutions: Well-Safe Solutions is a dedicated offshore well decommissioning specialist with its own tooling and project execution capability, competing for the same operator decommissioning budgets Decom targets.
