Exail: R7 Inspection ROVs and Maritime Robotic Systems
Review Exail R7 remotely operated inspection vehicles, payload choices and the Jan De Nul customer reference, with clear scope for maritime inspection and survey projects.
Company identity and heritage
Exail supplies robotics, maritime, navigation and other industrial technologies. ECA Group and iXblue joined under the Exail brand in 2022; the current company page identifies Exail as a subsidiary of Exail Technologies. Older ECA and iXblue documents may therefore describe relevant product heritage. This directory treats that shared operating brand as one company profile rather than counting the historical names again. Company overview; 18 October 2022 announcement.
R7 remotely operated inspection vehicle
R7 is a compact remotely operated vehicle, or ROV, intended for underwater observation and inspection. Exail describes a modular digital architecture supporting different sensors and tools, with a five-function manipulator available as an additional configuration. Its civil applications include submerged structures such as bridges, dams, ports and wind farms. Specify the complete sensor and tool package; the product family description is not a list of equipment included in every purchase. R7 product page.
Inspection and survey roles
Exail's renewable-energy portfolio distinguishes R7 inspection work from DriX surface survey vehicles, FlipiX towed systems and subsea positioning equipment. These systems perform different roles in a survey or maintenance project. Define the inspection question first, then determine whether the work requires close visual observation, acoustic imaging, positioning, wider-area survey or a combination. R7 remote operation should not be described as unattended autonomous inspection. Renewable-energy applications.
Jan De Nul customer reference
An Exail customer story dated 24 June 2025 describes Jan De Nul using R7 for vessel inspections and marine engineering work. Reported tasks include examining propellers, rudders and hulls, as well as checking seabed geotextile and rock-block alignment on an artificial-island project in Dubai. This supplier-published account illustrates the inspection workflow. It does not establish identical visibility, setup time or results at another location. Jan De Nul customer story.
Site and payload requirements
Provide the target structure, depth range, water clarity, expected currents, launch location and available working space. Identify tether-management constraints, obstacles and the required distance from the inspection surface. Ask the supplier to confirm the depth rating, navigation and imaging performance of the exact configuration. Assess whether the selected camera and sonar can capture the defect types that the asset owner actually needs to evaluate.
Data and inspection deliverables
Agree how video, sonar records, position information and operator observations will be associated with each asset. Define the coordinate reference, timestamp requirements, inspection coverage and file exports. Require sample deliverables that can be reviewed by the intended engineer or asset-management team. Distinguish a recorded observation from an engineering assessment of structural condition, and assign responsibility for interpreting uncertain findings.
Demonstration and lifecycle support
During a representative trial, evaluate controllability near the structure, usable image quality, recovery arrangements and the time required for deployment and routine checks. Test the proposed reporting workflow with real reviewers. Ask for operator training, replaceable-module availability, inspection intervals and support arrangements. Keep acceptance criteria tied to the required inspection evidence rather than a demonstration of vehicle movement alone.
Sources and enquiry preparation
Primary sources were reviewed on 11 September 2026. Manufacturer pages and the dated customer story support the portfolio description above. Prepare an inspection brief with asset drawings, environmental conditions, required evidence and the planned operating team. Request separate scope for the vehicle, tether and control equipment, payloads, launch support, training, software and ongoing service.
