EPI Group provides unexploded ordnance (UXO) risk mitigation consulting services for the Renewable, Oil & Gas, and Construction & Infrastructure sectors. EPI Group have joined forces with NjordIC, an international specialist in offshore UXO consultancy, to provide comprehensive marine UXO risk mitigation services.
As one of the leading offshore UXO consultancies, NjordIC has expanded its capabilities across the Americas and Asia-Pacific, delivering full-spectrum UXO consulting services including threat and risk assessment, UXO survey data analysis, UXO target investigation supervision, and UXO ALARP certification.
Whether project requirements are marine or terrestrial, EPI Group and NjordIC combine hydrographic, geophysical, environmental, and HSE expertise to ensure UXO risks are reduced to As Low As Reasonably Practicable (ALARP), in full alignment with international best practice.
UXO Mitigation Flow
EPI/NjordIC apply a systematic, stepwise approach to ensure safe, efficient, and transparent UXO risk mitigation. Each phase is supported by verified data, clear communication, and ALARP-driven decision-making.
Phase 1 – Historical Research (Desk-Based Assessment)
EPI/NjordIC begin by conducting a detailed historical and conflict analysis using archives, military records, and post-war documentation. This establishes the potential for UXO presence within the project area and forms the foundation of the UXO Threat Assessment.
Phase 2 – UXO Threat & Risk Assessment
Building on the historical findings, we assess the likelihood of presence and potential impact of UXO encounters based on planned project activities. The outcome defines the UXO risk zones, the applicable UXO threshold and provides tailored mitigation recommendations aligned with project-specific tolerances.
Phase 3 – Survey Planning & Data Review
We define survey objectives, detection thresholds, and coverage requirements to ensure detection of relevant UXO types. When survey data is provided, NjordIC’s Remote Data Centre (RDC) performs quality control, anomaly review, and prioritisation of potential UXO (pUXO) targets.
Phase 4 – Target Assessment & Master Target List
All geophysical anomalies are reviewed, classified, and consolidated into a Master Target List (MTL). This list ranks targets by risk level and guides subsequent investigation and clearance operations.
Phase 5 – Target Investigation & Identification
During the investigation phase, UXO specialists assess each target using remotely operated tools or divers, verifying whether anomalies are UXO or benign items. We provide supervision, on-call consultancy and quality assurance throughout the process.
Phase 6 – Clearance & Verification
If UXO are confirmed, they are safely removed or neutralised by authorised EOD teams under our supervision. All activities are verified and documented to ensure full compliance with national and international regulations.
Phase 7 – ALARP Certification & Reporting
Upon completion of investigation and clearance, we evaluate residual risk and issues an UXO ALARP Certificate, confirming that UXO risk has been reduced to As Low As Reasonably Practicable. The final report provides transparent documentation of all actions and justifications for sign-off.
Why Choose Us?
The partnership between EPI Group and NjordIC unites two industry leaders with complementary strengths in geophysical expertise and UXO risk management. Together, the joint venture delivers a fully integrated, end-to-end solution for UXO mitigation across marine, offshore, and terrestrial environments.
1. Proven Expertise Across Domains
EPI brings decades of experience in geophysical and hydrographic survey design, data acquisition, and interpretation. NjordIC complements this with unmatched expertise in UXO historical research, risk assessment, and ALARP certification. The result is a seamless workflow from data collection to final UXO sign-off.
2. Integrated Data-to-Decision Approach
Through the collaboration, clients benefit from a single interface connecting survey, analysis, and risk management. NjordIC’s Remote Data Center (RDC) ensures real-time data processing, daily QA/QC, coverage checks, and anomaly evaluation, enabling informed and rapid decision-making throughout the project lifecycle.
3. Global Coverage with Local Understanding
We operate globally — with established presence in Europe, the Americas, and the Asia-Pacific region — ensuring that regional regulations, environmental sensitivities, and project standards are fully respected and efficiently applied.
4. ALARP-Focused, Transparent Process and Pragmatic Approach
Every stage of the UXO management process follows international best practice, with traceable documentation leading to As Low As Reasonably Practicable (ALARP) sign-off. Clients receive clear, auditable evidence supporting safety, compliance, and operational continuity. Our pragmatic approach ensures that solutions are not only technically sound and compliant but also efficient, cost-effective, and tailored to the operational realities of each project.
5. Single-Point Accountability
Our partnership offers a single point of contact and accountability, reducing project complexity, ensuring smooth communication, and delivering consistent quality from start to finish.
6. Proprietary Remote Data Center (RDC)
NjordIC’s proprietary Remote Data Center is a state-of-the-art platform designed to handle large-scale UXO survey datasets with unprecedented analytical depth and precision. Equipped with advanced AI-assisted tools, anomaly classification software, and scalable infrastructure, the RDC ensures rapid turnaround, enhanced data integrity, and complete traceability from raw survey data to verified target lists.
