What FATHOM GROUP LTD does

Fathom Group Ltd is a private, Aberdeen-headquartered engineering services and software company founded in 2018 by Richard McGowan and Krzysztof Mackojc, operating in the offshore wind, oil & gas, decommissioning, and subsea engineering sectors. The company's product portfolio spans six engineering service lines (Subsea & Offshore Structural Engineering, Mechanical Design & Analysis, Marine & Subsea Dynamics, Finite Element Analysis, Engineering Software Development, Package Design) and a portfolio of turnkey engineered equipment including the Modular Recovery System, Pre-Piling Templates, Remote Release Hooks, and Subsea Baskets.

The company's central technology asset is METHOD, a physics-enabled analytical structural digital twin platform that combines first-principles engineering with AI for predictive subsea integrity, intelligent risk assessment, and automated engineering analysis. METHOD's core technical innovation is a proprietary frequency-domain solver that delivers structural assessments thousands of times faster than conventional time-domain approaches (with published benchmarking showing 10,000x speed over OpenFAST for a 5MW floating offshore wind turbine), while producing outputs grounded in DNV, ISO, and API engineering codes that remain transparent and auditable to integrity engineers and regulators. The platform is cloud-based with flexible dashboarding and is being co-developed with CGI for global offshore wind deployment and validated through the Elementz Tide Breaker subsea AI accelerator with Aker BP and Shell operator data.

Fathom's revenue model combines professional services (bespoke engineering consulting, structural analysis, FEED, detailed design, verification, and approval) with recurring software revenue (METHOD platform licensing/subscription) and one-time equipment project deliveries. Go-to-market is enterprise field sales supplemented by consortium partnerships (Industria, GuD Offshore Wind Polska, MEWO S.A. for Poland/Baltic offshore wind), event-driven lead generation (CORE 2025 headline sponsor, WindEnergy Hamburg 2024), and ecosystem participation (OREC Launch Academy, ONE Digital Tech Hub, North East VMS). The customer base spans offshore wind developers and operators (primary), oil & gas operators and Tier 1 contractors (secondary), decommissioning operators, and nuclear/fusion research (ITER).
