Underwater Intelligence —
Without the Risk
A Remotely Operated Vehicle (ROV) is a tethered underwater robot controlled from the surface — delivering live video, sensor data, and physical capabilities to depths and locations inaccessible or unsafe for human divers.
Modern compact ROVs have transformed what is operationally possible. Where traditional inspection once required a commercial dive team, specialist vessels, hours of preparation, and significant HSE risk exposure — today a single operator can deploy an ROV from a small vessel or dock within minutes.
Industries from offshore energy to aquaculture to municipal water utilities are replacing diver-dependent workflows with ROV-based inspection programmes — reducing costs by up to 90%, improving safety records, and generating richer data than manual methods can provide.

What ROVs Can Do
Six primary application categories covering the full spectrum of underwater robotic deployment — from infrastructure inspection to marine conservation.
Inspection & Asset Integrity
The largest ROV application category. ROVs deliver non-invasive visual and NDT inspection of underwater structures — eliminating the need for dewatering, scaffold rigging, or dive teams across virtually every industry.
Hull & Vessel Inspection
UWILD hull surveys, biofouling assessment, anode condition checks, propeller and rudder inspection — performed at anchorage without drydocking. Real-time video streamed to remote teams via Microsoft Teams or cloud platforms.
Ballast Tank & FPSO Inspection
Class-certified ballast tank surveys replacing rope-access teams. Hydromea's EXRAY reduced one FPSO inspection from 6 personnel / 4 days to 2 personnel / 2 days — cutting inspection costs by approximately 90%.
Offshore Wind Foundation Inspection
Monopile and jacket foundation inspection, bend restrictor surveys, inter-array cable inspection, and scour monitoring — without mobilising a support vessel. QYSEA W6 NAVI operates to 350 m with AI-assisted image enhancement in turbid water.
Dam, Reservoir & Hydropower
Turbine runner blade inspection, penstock surveys, and dam wall crack assessment — without shutdowns or dewatering. ROVs provide distortion-free HD video for proactive maintenance planning and early risk identification.
Pipeline & Subsea Infrastructure
Internal pipeline inspection for fouling, corrosion, and structural defects. External pipeline route survey, leak detection, and cathodic protection assessment. QYSEA completed a Kuwait petrochemical pipeline inspection in a single day — replacing a multi-week programme.
Port, Bridge & Civil Infrastructure
Quay wall and piling inspection, bridge scour monitoring, mooring system assessment, and underwater construction documentation. Aarhus Port identified silo structural failure risk before collapse using Blueye ROV inspections — preventing a major environmental incident.
Aquaculture Operations
ROVs have become standard operational equipment on modern fish farms. Daily net inspection, fish health monitoring, and environmental surveillance — replacing diver-dependent programmes with scalable, data-driven workflows.
Net & Cage Inspection
Regular net damage detection prevents fish escapes — a major financial and regulatory risk. ROVs enable daily visual inspection of all cage surfaces, mooring lines, and anchor systems. AI-assisted net damage detection flags issues automatically for faster response.
Fish Welfare & Mortality Monitoring
Real-time fish health observation, mortality detection and retrieval, feeding system inspection, and stocking density assessment. Water quality sensors measure pH, dissolved oxygen, salinity, turbidity, and temperature — providing environmental context for health data.
Offshore Energy
Oil & gas and offshore wind operations depend on continuous subsea asset integrity. ROVs provide real-time monitoring, structural assessment, and equipment verification — dramatically reducing costly vessel mobilisations and diver risk exposure.
Platform & FPSO Inspection
Jacket structure inspection, conductor guide surveys, riser assessment, and anode consumption monitoring. Equinor saved one million NOK per avoided specialist vessel hire through routine platform inspection with Blueye ROVs on the Kristin and Ivar Aasen fields.
Offshore Wind Asset Inspection
Monopile installation monitoring, transition piece surveys, inter-array cable inspection, cathodic protection assessment, and marine growth evaluation. Direct power supply enables 24/7 continuous operation — no battery recharge delays for extended inspection campaigns.
Search, Rescue & Security
ROVs provide situational awareness, evidence recovery, and threat assessment in missions where diver deployment is dangerous or impossible. Rapid deployment and extended reach make them indispensable for law enforcement, coastguard, and defense operations.
Search & Rescue Operations
Missing person searches, post-incident underwater evidence recovery, and rapid pre-dive survey for emergency responders. The Norwegian Coast Guard recovered a victim at 100 m depth using a Blueye ROV — a depth unreachable by their own divers. Deploy time: under 5 minutes.
Harbor & Critical Infrastructure Security
Port perimeter surveillance, vessel hull security checks for foreign objects or contraband, and bridge/dam integrity monitoring for threat identification. Norwegian Customs deploys Blueye ROVs for frequent commercial vessel hull checks — eliminating dependence on contracted dive services.
Defense & Naval Operations
Military vessel hull threat inspection, EOD support, IED investigation, and submarine maintenance assessment. Fielded by the Norwegian Coast Guard, Royal Netherlands Army, and Royal Australian Navy. Class-certified for visual and NDT data collection in defense contexts.
Scientific Research & Environmental Monitoring
ROVs have democratised access to underwater environments for research institutions. Where expeditions once required large vessels and specialist pilots, modern compact ROVs can be deployed by a single researcher within minutes — anywhere in the world.
Marine Biology & Habitat Monitoring
Coral reef health assessment, species population surveys, marine litter mapping, and climate change impact documentation. Used by NTNU, UNIS, and University of Tromsø to monitor northward species migration — revealing ecological change invisible from the surface.
Environmental Impact Assessment
Pre- and post-development surveys for offshore projects, water quality monitoring, sediment analysis, and pollution source tracing. Modular payload systems integrate water samplers, sediment samplers, and multi-parameter sensors for comprehensive data collection in a single dive.
Oceanography & Seafloor Mapping
Bathymetric mapping, volcanic activity monitoring, geological surveys, shipwreck documentation, and underwater archaeology. QYSEA's U-INS inertial navigation enables fully autonomous 3D path planning and repeat inspection with centimetre-level positioning — ideal for change detection over time.
Survey, Mapping & Documentation
High-quality underwater documentation — from photogrammetry and digital twins to cinematic film production. ROVs deliver data quality and consistency impossible to achieve through manual diving.
Photogrammetry & Digital Twins
Systematic visual documentation for 3D photogrammetric models, digital twin creation, and change detection baselines. DVL-enabled station-keeping ensures consistent frame geometry and enables precise repeat-survey positioning for longitudinal condition monitoring.
Film, Television & Media Production
Cinematic underwater footage for documentaries, commercials, and live broadcasts. QYSEA's ZEN-V supports full cinema-grade cameras (ARRI/RED) with 60 kg payload capacity and programmable crane-like movement. The V-EVO delivers 4K 60fps with real-time HDMI lossless streaming for broadcast-ready output.
Inspection Reporting & Compliance Documentation
Automated inspection report generation from dive footage, cloud-based fleet management, and regulatory compliance documentation. Blueye Cloud and QYSEA platforms generate structured reports with timestamped video, GPS coordinates, and annotated findings — reducing post-inspection reporting time by hours.
