OceanAlpha’s Proven USVs for Every Marine Survey Challenge

OceanAlpha has redefined reliability in marine survey—with a proven fleet of USVs ranging from compact 4.5m models to mission-ready 20m+ platforms, delivering over 70 nos. of unmanned vessels to global clients over the past years.

This scale-driven maturity means we understand every challenge—from shallow coastal complexities to deep-water asset inspections—and have built tailored solutions to solve them.

Offshore Energy Asset Inspection

Challenge: Inspecting subsea cables, wind turbine foundations, and pipelines for corrosion, cracks, or fatigue damage is slow and risky for divers or remotely operated vehicles (ROVs), especially near complex structures in bad weather.

OceanAlpha Solution: Our 24m USV + ROV combo provides turnkey solution for deep-water energy inspections, significantly reducing project downtime compared to traditional methods.

Shallow Offshore Surveying

Challenge: Shallow coastal waters and shifting seabeds (like erosion zones or reclaimed areas) make traditional crewed vessels risky—deep drafts may ground them, while divers face danger inspecting subsea cables and pipelines for hidden structural issues.

OceanAlpha Solution: OceanAlpha’s compact, shallow-draft USVs access hard-to-reach zones near shores and seabed interfaces. They pinpoint anomalies (like buried cable segments or localized scouring), and operate in fleets to map extensive pipeline networks efficiently.

Dynamic Ocean Observation

Challenge: Fixed buoys and research ships miss dynamic ocean processes and struggle to collect data in harsh weather or remote zones.

OceanAlpha Solution: OceanAlpha USVs can track moving ocean features (e.g., temperature shifts or nutrient flows) using onboard environmental sensors. They work tirelessly for weeks in tough conditions, filling data gaps left by stationary platforms.

Cost - Effective

USVs consume less energy and have no crew - related expenses, greatly reducing long - term operational costs for offshore wind farm inspections.

Inspection Precision

Equipped with advanced navigation, USVs can make precise maneuvers. They can get close to pile foundations for high - resolution detection, ensuring accurate inspections.

Security Reinforcement

Able to conduct continuous monitoring, USVs remove surveillance gaps in offshore areas. They promptly spot and handle any unauthorized entries, enhancing security.

Operational Safety

Operating in the tough offshore environment, USVs keep human workers out of harm's way, protecting lives and assets during wind farm operations.

Rapid Large-Scale Surveying

Unmanned vessels quickly map extensive seabed areas, accelerating project planning with faster, automated data collection.

Access Hard-to-Reach Zones

USVs can operate in complex nearshore waters and shallow areas where conventional vessels can't reach, ensuring complete site coverage.
