What Cathie does
Cathie is a specialist offshore geoscience and geotechnical engineering consultancy founded in 2005 and headquartered in Newcastle upon Tyne, United Kingdom. The firm delivers integrated seabed and sub-surface engineering solutions to global energy and marine infrastructure clients, with a primary focus on offshore wind (fixed-bottom and floating), oil and gas developments, submarine power and telecommunications cables, and port and LNG terminal infrastructure. Its track record spans more than 1,100 projects across 90+ countries, including engineering support for over 90 GW of offshore wind capacity, 400+ oil and gas projects, and 17,000+ km of submarine cable routes.
Cathie's technical platform rests on proprietary in-house software tools — OPILE for pile foundation analysis, plus JACA and CAISSON for geotechnical and structural calculations — combined with finite element, finite difference, and machine learning analysis methods. The firm has co-authored the Carbon Trust Cable Burial Risk Assessment (CBRA) guidelines and contributed to API and ISO standards, embedding its know-how into industry reference methodology. Delivery is led by a staff of approximately 90 specialist engineers operating from offices in the UK, Belgium, France, and Italy.
The business model is professional services: project-based engineering consultancy engagements with multi-year framework agreements for anchor clients. Cathie serves enterprise customers across the offshore energy value chain — including Shell, Orsted, TotalEnergies, ExxonMobil, Subsea7, Vattenfall, SSE Renewables, EDF Renewables, Perenco, ENI, TechnipFMC, and Heerema — and operates transmission system clients such as Elia and 50Hertz under long-term frameworks. The firm is privately held following its 2016 acquisition by Pont.

Products and services
- OPILE Commercial software program designed to analyze the capacity and response of single piles subjected to axial, lateral and torsional loads; computes pile capacities (ultimate and mobilisable), response curves (T-Z, Q-Z and P-Y), Soil Resistance to Driving, axial/lateral load-displacement response, and performs back-analysis of SRD based on pile driving records. Includes ALLCAP for sensitivity analysis and PROWEAP for back-analyzing soil resistance from hammer records. Used by engineers for piled jacket, monopile, and anchor pile design.
- JACA (Jack-up Leg Penetration Software) Bespoke in-house engineering tool for jack-up leg penetration calculations implementing SNAME, ISO 19905-1 and InSafeJIP methods, plus mechanism-based and strength averaging approaches. Used internally by Cathie engineers only; not commercially available.
- CAISSON Bespoke in-house software providing rapid dimensioning tool for Suction Installed Caissons (SICAs) embedded in a 2-layer cohesive soil, including inverted catenary solution for embedded chains. Used internally by Cathie engineers only.
- Feasibility Services Consultancy services covering site suitability, desk studies, geohazard assessment, concept design and risk management, designed to enable key strategic decisions at the front end of offshore projects.
- Development Services Survey consultancy, data management, integration and interpretation, ground modelling, cable burial risk assessment (CBRA), and route design services to define site conditions and quantify risk during the project development phase.
- Design Services Engineering solutions for offshore infrastructure interacting with seabed, including pipelines, foundations, anchors, and cables; uses finite element, finite difference and machine learning methods to lower CAPEX and improve reliability.
- Installation Services Practical engineering support for installation issues including jack-up analysis, trenching and burial assessment, foundation and anchor installation support, and pile driving monitoring delivered through sister company G-Octopus.
- Operation Services Services for dynamic marine environments including cable integrity risk assessment, remedial design, design re-evaluation for life-extension, decommissioning studies, and ongoing risk management for operational offshore assets.
- Cable Route Engineering and CBRA Subsea cable consultancy including landing site and route corridor definition, routing design, burial risk assessment (CBRA), burial assessments, and thermal conductivity modelling; Cathie co-authored the Carbon Trust Cable Burial Risk Assessment Guidelines.
