Subsea Target Investigation

Operational Integration

Working Alongside Dive Teams

Our EOD Engineers operate as part of the wider dive and marine spread. They understand commercial diving procedures, ROV operations, vessel management and the pressures of programme delivery.

From mobilisation through to demobilisation, UXO considerations are integrated into the daily workflow — not treated as a separate activity. Whether supporting diver operations or ROV investigation, our approach ensures seamless integration with existing marine procedures.

Refining Target Selection

Prior to mobilisation, our engineers work with geophysical teams to refine potential UXO target lists. By reviewing anomaly data collaboratively, we help reduce unnecessary investigation while ensuring credible threats are not overlooked.

This supports efficient dive time allocation, optimised ROV deployment, and controlled subsea exposure; reducing operational costs while maintaining appropriate safety standards.

Investigation & Identification

Real-Time Technical Judgement

During target investigation, our engineers provide immediate assessment of items that may present as potential UXO. Their presence, whether supporting diver operations or ROV investigation, ensures that identification decisions are informed, proportionate and defensible.

Advanced EOD Engineers draw on extensive operational experience with ordnance types, fuzing mechanisms, and degradation states to deliver confident classification. Real-time communication ensures immediate escalation when required and swift clearance when targets are confirmed as non-UXO.

Reporting & Regulatory Compliance

Where required, we manage reporting to relevant national authorities through established procedures. This ensures regulatory obligations are met without disrupting operational continuity.

Clear communication and defined escalation routes underpin safe decision-making. Comprehensive investigation reports include target coordinates, photographs, measurements, identification, and recommendations for avoidance, relocation, or disposal.

Safety in Practice

Subsea target investigation of UXOs involves proximity, exposure and environmental variables. Safety is therefore embedded through:

• Structured pre-task planning

• Defined roles and responsibilities

• Clear authority for work stoppage if required

• Continuous liaison with dive supervisors, ROV pilots and vessel masters

• Equipment inspection and maintenance protocols

• Emergency response procedures and evacuation planning

Our engineers understand that safe outcomes depend on calm, disciplined execution in real offshore conditions, whether operating at 5 metres or 50 metres depth.

The 15-metre threshold represents the optimal transition point between diver and ROV deployment, balancing operational efficiency, safety considerations, and investigation effectiveness:

Deeper than 15m

ROV operations eliminate decompression constraints, extend bottom time, and maintain capability in challenging environmental conditions.

15m depth and less

Divers provide superior hands-on capability, faster mobilisation, and greater tactical flexibility for shallow water complexity.

Depth Selection & Method Optimisation

Supporting Controlled
Near-Shore Progression

By integrating ordnance expertise directly into subsea operations, we help clients manage UXO risk proportionately and safely across all water depths.

The result is controlled investigation, reduced uncertainty and confidence for both operators and regulators, delivered through deployment methods optimised for each specific operational environment.
