7. Water Tank Inspection

ROVs offer a safe, efficient solution for water tank safety audits, inspecting tank bottoms and shells with visual checks, spot cleaning, and UT thickness testing services without human entry. They reduce downtime, enhance safety, and provide high-quality data, making them ideal for water storage tank inspections and structural integrity assessments in confined environments.

8. Reef Inspection

ROVs enable non-intrusive, high-resolution coral reef health assessments, vital for monitoring rocky reefs that support diverse marine life across various depths and climates. These reefs sustain complex ecosystems, and ROVs facilitate marine reef inspection dives, aiding conservation and research efforts without disturbing the environment.

9. Biodiversity and Habitat Monitoring

ROVs are vital for biodiversity monitoring field services, capturing detailed visuals and geolocated data in hard-to-reach marine ecosystems using HD cameras and sensors. With tools like side scan sonar, they enable environmental habitat monitoring services and non-intrusive seabed mapping, supporting marine research and conservation without disturbing sensitive underwater habitats.

10. Offshore Platform Inspection

ROVs play a key role in offshore platform safety audits, providing safe, efficient access to underwater areas. Using HD cameras, sonar, and NDT tools, they detect corrosion, cracks, and marine growth, ensuring offshore structural integrity checks and regulatory compliance while reducing downtime without risking diver safety.

11. SPM PLEM Inspection

ROVs provide safe, efficient SPM PLEM integrity checks for Single Point Moorings (SPMs) and Pipeline End Manifolds (PLEMs), key offshore transfer points for oil and gas. They deliver high-resolution visuals and sensor data to detect wear and damage, enhancing mooring system safety inspections, regulatory compliance, and maintenance while reducing reliance on divers.

12. X-mas Tree, Risers, and Umbilical Inspection

ROVs facilitate safe, real-time X-mas tree integrity audits and inspections of subsea risers and umbilicals—key components in offshore oil and gas flow control. Utilizing advanced sensors and imaging systems, they detect corrosion, ensuring riser system safety inspections and compliance with industry regulations. By eliminating divers, ROVs prevent failures and support uninterrupted offshore production.

13. FPSO Inspection

ROVs play a critical role in FPSO safety inspection services for subsea systems, including moorings, risers, and turrets, particularly in deepwater or hazardous environments. Equipped with advanced imaging sonar, they enable floating platform condition audits, detecting corrosion, fatigue, and structural anomalies, ensuring safety, regulatory compliance, and optimized maintenance to extend FPSO operational life.

14. Subsea Pipeline Inspection

Remotely Operated Vehicles (ROVs) are crucial for subsea pipeline integrity checks, identifying corrosion, cracks, and free spans using high-resolution cameras, sonar, and advanced sensors. Capable of operating in deep environments without interrupting production, ROVs deliver accurate geolocation data, ensuring offshore pipeline safety inspections and long-term reliability of pipeline systems.

15. Vessel Inspection

ROVs provide a safe, efficient way to conduct vessel safety inspection services, inspecting hulls, propellers, and rudders while afloat, reducing dry-docking needs. Using high-resolution cameras and sensors, they detect corrosion, damage, and marine growth in real time, supporting marine vessel condition audits and ensuring structural integrity and navigational safety.

16. Geosynthetic Tube Inspection

ROVs offer a safe, efficient solution for geosynthetic tube integrity checks used in shoreline protection. Outfitted with cameras and sonar, they detect tears, displacement, and deformation, while evaluating sediment accumulation. This non-intrusive approach ensures coastal geosynthetic tube inspections maintain structural integrity, performance, and durability without divers.

17. Breakwater Inspection

ROVs provide a safe, efficient method for breakwater structural safety audits, identifying armor unit displacement, scouring, cracks, and marine growth. Equipped with high-definition cameras, sonar, and positioning systems, they capture precise underwater data for coastal breakwater condition checks, enhancing structural stability assessments and supporting timely maintenance of coastal defense structures.

18. Shipwreck Survey

ROVs enable safe, non-intrusive shipwreck underwater survey services for archaeology, environmental studies, and investigations.
