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.
What are you looking for?
Two ways in. Pick the technology if you already know what you need — or tell us the job and we'll match the right technology to it.
I know the technology
Go straight to a category and compare honestly across every brand we carry.
I have a job to do
Not sure which technology fits? Start from your mission and let us narrow the fleet for you.
Six Categories, One Partner
The whole portfolio, organised by what the technology is — so you can find and compare the right systems fast. Every category links through to the full range and the brands behind it.
ROVs & Underwater Drones
From 8 kg single-operator inspection drones to 130 kg observation-class systems. Seven manufacturer partnerships under one roof — compare honestly across brands and match the platform to the mission.
Autonomous Vehicles
Man-portable autonomous underwater vehicles and a foldable catamaran surface vessel — for large-area seabed mapping, UXO detection, environmental monitoring and hands-off survey. Open Linux / ROS autonomy.
Sonar & 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.
Sensors & Payloads
Whatever platform you run, the same cross-supplier catalogue completes it — cameras, lighting, sonar, DVL & USBL, manipulators, tether and controllers. Sourced, integrated and quoted through one partner.
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.
Not sure where to start?
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.

Try Before You Buy
Access professional-grade underwater ROVs without capital investment. From 8 kg inspection drones to the 130 kg DWTEK I90+ observation-class system — fully pre-tested, insured, and operator-support available worldwide.
Your Dedicated Marine Robotics Partner
We don't just sell hardware — we help you choose the right system, get it operational, and support it throughout its life. Here's what that means in practice.
Authorized Distributor
Official distribution agreements with the brands we carry — full manufacturer warranty, genuine spare parts, and direct factory support channels backed by SepcoTech.
Mission-First Selection
We help you choose the right system for your mission profile, depth, environment, and budget — not just the most expensive option. Honest advice from engineers who deploy these systems.
Service & Support
Training, commissioning assistance, maintenance, and spare parts supply. When something goes wrong in the field, you reach our team — not a support queue in another country.
Try Before You Buy
Use our rental fleet to evaluate platforms before committing capital. Many customers confirm their purchase decision after running a rental mission with the actual system.
Talk to Our Marine Robotics Team
Whether you're scoping a project, comparing systems, or ready to purchase or rent — our team is available to advise, demo, and quote. No obligation.
