What Ordtek does

Ordtek is a UK-based engineering consultancy founded in 2012 by UXO specialist Lee Gooderham, providing unexploded ordnance (UXO) risk management services across land and marine developments. The company became a wholly-owned subsidiary of Venterra Group in 2021 and operates as a core component of the Venterra Geoscience division, with offices at the Hethel Engineering Centre in Norfolk and a registered address in Diss.

The company's core technology asset is "The Vault," a proprietary database containing nearly 60,000 historical UXO data sources — including WW1/WW2 mine maps, ship logs, air raid reports, EOD task records, military exclusion zone maps, and previous UXO desktop studies — curated by dedicated archivists and historians. This archive underpins an eight-phase UXO risk management framework that integrates geoscience techniques with risk management methodology, enabling services such as UXO Hazard Assessments, Offshore Risk Assessment and Mitigation Strategy, Offshore UXO Survey Support, Target Identification and Clearance Campaign Support, ALARP Sign-Off certification, and UXO Residual Risk Management. The company also delivers onshore UXO risk assessments, geophysical survey technical specification and management, target grading and modeling, EOD engineer site supervision, safety and awareness briefings, and survey client representatives. Ordtek reports that its approach reduces geophysical anomalies requiring investigation by over 90%, and its ALARP sign-off is positioned as a means to discharge legal UXO liabilities for clients.

Commercially, Ordtek operates a B2B sales-led go-to-market targeting enterprise clients including offshore wind developers (RWE, Ørsted, SSE, Equinor), subsea cable operators (National Grid/Viking Link), and infrastructure developers across 30+ countries in Europe, Asia Pacific, and North America. Revenue is generated through project-based professional services engagements with quote-based pricing, 30-day payment terms, and project scoping tailored to environment, geography, complexity, and duration. The customer base spans major projects such as Hornsea, Dogger Bank, Greater Changhua, Empire Wind, Beacon Wind, South Fork, Revolution, Formosa, Moray East & West, and Viking Link. As part of Venterra Group's 700+ personnel platform spanning 15 countries, Ordtek benefits from cross-selling and integrated delivery alongside sister companies CAPE Holland, Osbit, and Oceanscan. The company holds ISO 9001, ISO 45001, and Netherlands Safety Culture Ladder Level 3 certifications, which are commonly required for offshore wind procurement.

Emerging players

• Cathie Group: Independent geoscience and engineering consultancy focused on offshore wind, providing integrated ground modelling and geotechnical services. Adjacent to Ordtek within Venterra Group's geoscience peer set, with overlapping customer base among offshore wind developers.

Broad incumbents

• RPS Group: Large multi-disciplinary engineering and environmental consultancy providing offshore wind development services including survey, environmental, and consenting support. Competes at the broader project level rather than as a UXO specialist, but can absorb UXO work into integrated packages.
• Fugro: Global geo-data specialist providing geophysical, geotechnical, and survey services to offshore wind developers. While not a UXO specialist, Fugro runs the geophysical surveys Ordtek supports, giving it the ability to bundle UXO-related interpretation or to compete for adjacent scopes.
• Saipem: Major offshore EPCI contractor active in offshore wind installation and oil & gas decommissioning. Competes indirectly for project scopes where UXO risk management is bundled into wider offshore construction contracts.
• Wood Group: Large global engineering and energy services firm with significant offshore wind and oil & gas decommissioning exposure. Can deliver integrated decommissioning and infrastructure packages that include UXO management as one component, competing with Ordtek on bundled scopes.

Direct peers

• Risktec (TÜV Rheinland): Risk and safety consultancy with a dedicated UXO risk practice serving offshore wind and infrastructure developers. Competes with Ordtek on UXO hazard assessment, ALARP, and integrated risk management for offshore and onshore projects.
• 1st Line Defence: UK-based UXO risk management consultancy providing desktop threat assessments, on-site support, and clearance services for construction and infrastructure projects. Competes directly with Ordtek in onshore and offshore UXO consultancy.
• 6 Alpha Associates: UK-based specialist UXO risk management consultancy serving offshore wind, subsea cable, and onshore infrastructure developers. Direct competitor to Ordtek on hazard assessments, ALARP sign-off, and survey support across the UK and Europe.
• Wessex Archaeology: Major UK heritage and archaeology consultancy with an established UXO and unexploded ordnance service line for offshore renewables, subsea cables, and infrastructure. Overlaps Ordtek in desktop UXO assessment and offshore survey support.
• BACTEC (Dynasafe / Esken): Specialist UXO risk assessment and clearance provider operating across land and marine environments, with a long track record in offshore wind, subsea cable, and harbour projects. Direct competitor on ALARP sign-off and survey support services.
