Tethys ONE: A Technical Look at a Versatile Next-Gen ROV
The Tethys ONE ROV is engineered for demanding subsea operations, combining portability with advanced performance. Whether for offshore industrial inspections or mission-critical SAR & UXO detection, its modular design and robust sensor suite make it a powerful and adaptable underwater tool.
Technical Specifications
Dimensions & Build
Compact footprint designed for rapid deployment in offshore and nearshore environments.
Lightweight frame suitable for vessel, shore, or rapid-response deployment scenarios.
Modular design for quick payload integration.
Depth Rating
Capable of operating at significant depths (spec sheet-defined), ensuring coverage for both shallow inspections and deepwater missions.
Propulsion & Maneuverability
Multiple vectored thrusters for 6 degrees of freedom (DOF) movement.
Excellent station-keeping ability, even in currents, ensuring precision for survey and intervention tasks.
Speed optimized for both stable inspections and rapid response maneuvers.
Power & Endurance
Designed for efficient energy use, enabling extended subsea missions.
Power input compatible with offshore deployment systems.
Imaging & Sensors
High-definition camera systems with low-light sensitivity for visibility in challenging subsea conditions.
Optional integration of multibeam sonar for target recognition and wide-area scanning.
Configurable payload options such as non-contact cathodic protection sensors, environmental sensors, or UXO-specific detection equipment.
Payload & Tooling
Payload capacity sufficient for SAR recovery tools, UXO sensors, or offshore inspection modules.
Quick-swap payload bays make configuration fast and flexible.
Offshore Applications
For energy and infrastructure, Tethys ONE supports:
Subsea pipeline and cable inspection.
Structural monitoring of platforms, risers, and moorings.
Environmental surveys and seabed mapping.
Its compact design means it can be deployed rapidly from smaller vessels, reducing operational costs compared to heavy work-class ROVs.
SAR & UXO Capabilities
In search and rescue missions, the Tethys ONE excels by:
Providing real-time imaging for locating submerged objects or persons.
Supporting recovery operations with payload integration for grabs or recovery lines.
For UXO detection and clearance, the ROV can be configured with:
Sonar arrays for wide-area scans.
High-definition video for positive identification.
Sensor payloads that allow safe, remote UXO investigation without diver risk.
Key Advantages
Versatility: One platform for multiple industries and missions.
Scalability: Modular payloads adapt to mission needs.
Efficiency: Quick deployment, low logistical overhead.
Safety: Reduces the need for diver intervention in hazardous environments.
The Tethys ONE is more than a compact ROV — it’s a high-performance subsea platform that bridges the gap between industrial-grade capability and rapid, accessible deployment. From offshore inspections to life-saving SAR operations and safety-critical UXO clearance, it delivers the technical performance professionals can rely on.
