Deep-sea seabed nodes operating on the ocean floor

CASGEO · Mobula node

Empowering deep-sea exploration with intelligence

The next-generation self-navigating ocean-bottom node, Mobula (Ocean-Bottom Flight Node), combines autonomous positioning, precise seabed deployment, and large-scale scalability. It revolutionizes traditional deep-sea OBN exploration with a cable-free and ROV-free recovery system.

Core Technology

Core Values: Three

From deployment and observation to retrieval, the Mobula node covers the entire deep-sea exploration workflow with a differentiated technical approach.

Wireless Flight and Swarm Coordination

Cable-free autonomous deployment: Nodes use an onboard micro-propulsion system to fly underwater and land precisely after being released from the mother ship, enabling rapid wide-area array deployment without tether constraints.

Buoyancy Adjustment and Automatic Retrieval

Upon completion, the unit automatically lifts from the seabed using its smart release mechanism. The mother vessel then retrieves multiple units in a single batch, significantly reducing the risk of equipment loss and cable entanglement.

End-to-end closed loop from seismic source excitation to receivers

Supports air-gun source excitation. The array delivers high-fidelity, synchronized clock-triggered reception, completing the deep-sea seismic survey loop from source activation to data acquisition.

Applications

Deep-Sea Application Scenarios

Covering deep-sea oil and gas exploration, mineral exploration, disaster monitoring, CCUS, and offshore wind.

Deep-Sea Oil and Gas Exploration

High-precision geophysical exploration technologies accurately locate deep-sea oil and gas reservoirs, providing reliable data support and a geological foundation for energy development.

Deep-Sea Mineral Exploration

Maps the distribution and reserves of strategic mineral resources, including polymetallic nodules and cobalt-rich crusts, to support sustainable marine resource development and utilization.

Deep-Sea Disaster Monitoring

Real-time monitoring of marine geological hazards—including seabed earthquakes, tsunamis, landslides, and turbidity currents—to support ocean disaster prevention and mitigation research.

CCUS Carbon Sequestration Monitoring

High-resolution time-lapse (4D) seismic monitoring for offshore CO₂ storage, with periodic repeat surveys to track plume migration paths and containment boundaries.

Offshore Wind Farm Site Selection and Monitoring

High-resolution seabed geological imaging identifies hazards such as faults and shallow gas; foundation scour monitoring and cable route inspections are performed during the operational phase.
