Underwater ROV, Sonar & Cleaning Systems

Explore OMNI UXV observation and work-class ROVs, hull-cleaning platforms, side-scan sonar and underwater imaging instruments.

Category brief

Start with the operating problem

Underwater systems must be matched to depth, current, visibility, tether length, payload, launch method and the work the vehicle is expected to perform. A sonar that excels at search is not automatically the best tool for close inspection.

OMNI UXV combines vehicle, sensing and operator-workflow selection. The reference portfolio spans ROV inspection and cleaning, side-scan search, multibeam bathymetry and close-range acoustic imaging.

Technology guide

How to choose an underwater ROV and sonar system by evidence need

Underwater inspection systems should be selected by the evidence the mission must produce: broad seabed search, a bathymetric surface, close acoustic awareness, visual inspection, measurement, cleaning or intervention. An underwater ROV and sonar supplier should be able to explain how the vehicle, sensor, positioning, tether, topside power and crew form one operating system.

Depth rating alone is not a practical working envelope. Current, turbidity, obstructions, launch height, deck space, tether drag and the ability to relocate a finding often determine whether a technically capable instrument can complete the job.

01Efficient corridor and seabed search

Side-scan sonar

Side-scan sonar creates acoustic imagery across a swath and is useful for locating anomalies for later classification.

Selection note: Plan tow or vehicle stability, altitude, overlap, positioning and a target-reacquisition method.

02Bathymetry, depth surfaces and coverage measurement

Multibeam echo sounder

Multibeam systems measure depth across a swath and require disciplined calibration, positioning and sound-velocity control.

Selection note: Specify vertical and horizontal uncertainty, coverage, datum and deliverable format rather than beam count alone.

03Close navigation and structure awareness in low visibility

Imaging sonar

Forward-looking acoustic imagery helps an operator approach and inspect an object when cameras provide limited range.

Selection note: Match frequency, range, field of view, stand-off and update rate to the target and vehicle workflow.

04Visual confirmation, measurement, tooling, cleaning and intervention

Inspection or work-class ROV

An ROV carries cameras, sonar and tools to a known point of interest while the tether provides power or communications.

Selection note: Evaluate thrust, payload, tether, surface system, launch and recovery and the forces created by tooling or contact.

01

Water conditions

Define depth, current, salinity, turbidity, temperature and expected obstructions.

02

Evidence requirement

Determine whether the mission needs video, acoustic imagery, bathymetry or georeferenced targets.

03

Launch and recovery

Plan crew, deck space, power, tether management and safe recovery before selecting vehicle size.

Buyer workflow

From requirement to accepted configuration

Use the same decision sequence for every shortlisted product so that published specifications, project assumptions and delivered evidence remain comparable.

  1. STEP 01

    Define the evidence chain

    Separate search, target marking, reacquisition, close inspection and reporting.

    Output: Stage-by-stage mission plan

  2. STEP 02

    Survey water and access

    Record depth, current, visibility, obstructions, launch position, power and deck limits.

    Output: Environmental and mobilization envelope

  3. STEP 03

    Design positioning and records

    Choose coordinate, time, asset, target and file conventions before collection.

    Output: Survey control and evidence structure

  4. STEP 04

    Shakedown the complete crew

    Use a known target to test launch, search, marking, repeat approach and data transfer.

    Output: Representative system acceptance record

Before requesting a quotation

Questions a serious buyer should resolve

  1. 01Is the primary mission search, measurement, inspection, cleaning or intervention?
  2. 02How will the target or defect be positioned and found again?
  3. 03Which current, tether and launch limits define the real working envelope?
  4. 04What topside power, control, positioning and recording equipment is included?
  5. 05Can another crew reproduce a finding using the delivered report and raw evidence?

Selection questions

What is the difference between side-scan and imaging sonar?
Side-scan sonar is efficient for searching wider seabed corridors. Imaging sonar supports close-range awareness and inspection, especially when optical visibility is poor.
What determines practical ROV operating depth?
Vehicle rating is only one limit. Tether, connector, camera, payload, surface power, current, launch method and operational reserve all affect the safe working envelope.
Can a cleaning ROV be used on every hull coating?
Brush and operating parameters must be reviewed for the coating, fouling level and environmental rules. A site trial is recommended before production cleaning.
