Everything Marine Robotics,
under one roof
ROVs and underwater drones, autonomous vehicles, sonar and positioning, hull-fouling analytics, a worldwide rental fleet and the accessories that tie them together — SepcoTech brings the world's leading underwater technology brands into a single catalogue, backed by engineers who deploy these systems themselves.
One Source · Every Discipline
Your single home for underwater technology
Most underwater projects need more than one tool — an ROV to see the asset, a sonar to find it, an autonomous vehicle to survey the route, software to turn the dive into a report, and the right payloads to tie it together. SepcoTech brings every one of those disciplines under one roof, so you can compare honestly across brands instead of being sold a single line.
- Six complete solution areas — vehicles, sensing, software, rental and accessories
- Eleven-plus manufacturer partnerships, recreational to observation-class
- A rental fleet to evaluate platforms before you commit capital
- Training, commissioning, spare parts and field support from our own team
- Mission-first advice from engineers who dive with these systems
Six Solution Areas, One Partner
Everything we offer in marine robotics, mapped to the job it does. Five core platforms and services below — plus the cross-supplier accessories layer that completes them all. Start anywhere; every area links through to the full range.
ROVs & Underwater Drones
Seven manufacturer partnerships under one roof — from 8 kg single-operator inspection drones to 130 kg observation-class systems. Compare honestly across brands and match the platform to the mission.
AUVs & Underwater Acoustics
French man-portable autonomous underwater vehicles and passive acoustic monitoring — for seabed mapping, UXO detection, environmental compliance and marine-renewable assessment. Open Linux / ROS autonomy.
Sonar, Imaging & Positioning
Professional-grade acoustic imaging, subsea USBL positioning and single-beam bathymetry — at a fraction of traditional cost. Plug-in sensing for ROV navigation, inspection and seafloor mapping.
Hull Inspection & Fouling
Predict where fouling builds with data-driven Hull-Sight analytics, then prove what's really there with a class-certified, diver-free micro-ROV in-water survey. Run them as one loop or standalone.
ROV Rental
Access professional ROVs without capital investment — five systems from compact inspection drones to the 130 kg DWTEK I90+ observation-class platform. Fully serviced, insured, operator support, mobilised worldwide.
Accessories & Payloads
Whatever platform you run, the same cross-supplier catalogue completes it — 80+ add-ons across ten categories from six specialist brands, sourced and quoted through one partner. Pick a category to jump straight to it.

Answer a few quick questions about your mission, depth, environment, and budget — our ROV Finder matches you to the best platforms from across the whole portfolio.
From Survey to Decision
Hardware is only the start. Across every solution area the goal is the same — defensible, repeatable data, captured safely and turned into something your stakeholders can act on.
See what's down there — before you commit a single diver
Autonomous vehicles cover the route, imaging sonar cuts through zero-visibility water, and bathymetry builds the model of the seabed and the structure. Together they answer the first question of any subsea job: what is actually there, and where.
- Imaging sonar that works where cameras can't
- USBL positioning so every target has a coordinate
- Man-portable AUVs for large-area seabed survey
Turn a dive into a document stakeholders trust
An ROV flies in, lights the asset and streams 4K imagery with live telemetry — then logs every dive, tags the findings and exports a structured report. That traceable record is what turns a quick look into a defensible engineering or class deliverable.
- 4K imaging with live depth, heading & temperature overlay
- GPS-tagged dives logged and exported to PDF
- Class-certified in-water surveys without dry-docking
- Repeatable passes for change detection over time
Learn Where & How ROVs Work
Not sure where underwater robotics fits your operation? Our knowledge center documents 40+ real applications across 13+ industries, the technology behind modern ROVs, and case studies from the field — built to help you scope a project before you buy.
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.
Survey & Hydrography
Seabed mapping, bathymetry and large-area autonomous survey for route planning, dredging and marine-renewable projects.
Environmental & Research
Acoustic monitoring, sampling support, habitat mapping and compliance for scientists, consultants and universities.
Defence & MCM
Harbour security, ship-husbandry, UXO detection, mine countermeasures and naval inspection with rugged platforms.
The ROV Applications Knowledge Center
A complete, free-to-browse library: what ROVs can do, the industries they serve, the technology inside them, real-world case studies, and a guide to matching the right platform to your mission.
