UXO Marine Specialist Services
Subsea UXO risk management requires more than isolated services. It requires technical depth, offshore awareness and disciplined control from survey planning through to sign-off.
We provide specialist marine UXO expertise across the full lifecycle of offshore energy and infrastructure projects, ensuring risk is defined clearly and managed proportionately at every stage.
Subsea Ordnance & Risk Advisory
Geophysical Data Processing & Interpretation
What We Deliver
We process and interpret magnetometer data using recognised industry software and proven methodologies to identify anomalies that may represent potential UXO. Side scan sonar and, where beneficial, multi-beam data are incorporated to strengthen target understanding
How It Improves Project Control
Our geophysicists work closely with experienced EOD Engineers to refine anomaly lists and reduce false positives to the lowest practicable level. This minimises unnecessary target investigation, protects vessel time and supports informed decision-making.
Safety & ALARP Integration
Processed data feeds directly into ALARP-based certification and formal sign-off processes. By aligning interpretation with risk acceptance criteria, we provide clarity for developers, EPC contractors and regulators.
Survey Verification Testing & Surrogate Provision
Establishing Survey Confidence
Before full campaign rollout, survey verification testing confirms that equipment configuration, positional accuracy and data processing methods are fit for purpose.
We design verification specifications, provide controlled surrogate targets and oversee trial execution to ensure survey performance is validated early.
Controlled Surrogate Deployment
Our surrogate items are manufactured and maintained to known standards, with appropriate lifting arrangements and certification for safe handling offshore.
Why It Matters
Identifying configuration or processing issues during verification prevents costly downstream rework, protects installation schedules and strengthens regulatory confidence.
Verification enhances safety before operational exposure begins.
Offshore Client & EOD Representation
Operational Oversight
We provide experienced offshore representatives to oversee UXO survey and target investigation activities. This includes anomaly grading review, data capture quality control and confirmation of suitability for UXO identification and avoidance.
Integrated Governance
Offshore personnel are supported by our shore-based operations team, maintaining continuity, escalation capability and technical assurance.
Consistent oversight ensures survey data and investigation outcomes are aligned with project risk tolerances.
Real-Time Advisory Support
Where potential UXO is encountered, our representatives provide immediate guidance, ensuring safe management and appropriate reporting to relevant authorities.
Technical Advisory Notes (TAN)
Defining Safe Avoidance Radii
We prepare project-specific Technical Advisory Notes to assess the impact of intrusive offshore activities and define appropriate avoidance distances.
This may include cable installation, geotechnical investigation, anchoring, jack-up deployment, rock placement or other seabed interventions.
Supporting Proportionate Risk Management
Each advisory note is tailored to the specific operation and threat context. Clear definition of risk enables survey scopes and mitigation strategies to be optimised.
TANs provide structured evidence to support ALARP-based decisions and reassure contractors, insurers and stakeholders.
Munitions Migration & Burial Assessment (MMBA)
Understanding Seabed Dynamics
Munitions can migrate or become buried over time. We assess these dynamics using met-ocean, geotechnical, bathymetric and seabed morphology data, combined with project-specific desk study outputs.
Reducing Uncertainty
By understanding likely movement patterns, we provide assurance to project teams and third parties regarding seabed stability and evolving UXO risk.
Informed forecasting strengthens safety planning and protects programme certainty.
Informing Survey Longevity
MMBA supports decisions around survey validity periods and whether additional “just-in-time” survey is required prior to installation.
Emergency Response Planning & On-Call Advisory
Preparedness Before Exposure
We develop bespoke Emergency Response Plans for projects where UXO may be encountered unexpectedly. These plans define immediate actions, reporting procedures and escalation routes.
Training & Toolbox Briefing
We deliver emergency response training and UXO awareness briefings, both in person and remotely, ensuring crews understand roles, responsibilities and safety expectations.
24/7 On-Call Support
Where permanent offshore presence is not required, experienced EOD Engineers are available on-call to provide rapid advice and guidance.
Preparedness enhances control. Clear guidance supports safe response. Verification enhances safety before operational exposure begins.
Supporting Safe Offshore Progression
Across all advisory and operational services, our focus remains consistent:
define risk clearly, manage it proportionately and integrate UXO considerations seamlessly into offshore delivery.
This approach protects personnel, assets and programme integrity.
