Not sure which ROV is right for you?
Answer a few quick questions about your mission, depth, environment, and budget — our ROV Finder matches you to the best platforms from across our 7-brand portfolio.
From Dive to Deliverable
An ROV is only as valuable as the evidence it brings back. Across every platform we supply, the goal is the same — defensible, repeatable inspection data, captured safely and turned into a report your stakeholders can act on.
See the asset clearly — without putting a diver in the water
Confined ballast tanks, sea chests, intakes and flooded structures are exactly where diver access is slow, costly and risky. A compact ROV flies in, lights the space and streams 4K imagery with live telemetry overlaid — so the inspector sees and records the asset in real time, from the safety of the deck.
- Real-time depth, heading and temperature telemetry on screen
- High-output LED lighting for zero-ambient-light interiors
- Footage re-reviewed and re-measured offline for the report
Turn a dive into a document stakeholders trust
Modern inspection ROVs log every dive — time, duration, depth profile, GPS position and tagged observations — and export it straight into a structured report. That traceable record is what turns a quick look into a defensible engineering or class deliverable.
- GPS-tagged dives with depth and duration logged automatically
- Flag and annotate findings during or after the dive
- One-click export to PDF and reporting tools
- Repeatable passes for change detection over time
Built for Real Underwater Work
Across our portfolio there is a platform matched to the mission — from quick visual checks to quantitative survey, in harbours, offshore and inland water.
Hull & Class Inspection
Hull, propeller, rudder and sea-chest surveys plus in-water class inspections — documented in 4K without dry-docking the vessel.
Ports & Infrastructure
Quay walls, piles, pipelines, intakes and submerged structures — inspect and measure damage safely from the surface.
Aquaculture
Net integrity, mooring and biomass checks at fish farms — daily inspection without divers and without disturbing stock.
Search & Recovery
Rapid visual search, evidence recovery and incident response for public-safety, police and salvage teams.
Environmental & Research
Survey, sampling support, habitat mapping and monitoring for scientists, consultants and universities.
Defence & MCM
Harbour security, ship-husbandry, mine countermeasures and naval inspection with open and ruggedised platforms.
Accessories & Rental Fleet
Beyond the ROV itself — we supply the accessories, sensors, and payloads that complete your underwater operations, plus a rental fleet for project-based and short-term needs.
ROV Accessories & Payloads
Sonar systems, grippers, positioning beacons, lights, cameras, cable reels, surface control units, underwater connectors, and more — sourced from across our brand portfolio. Everything you need to build out your ROV system.
