An underwater inspection was carried out on a pier structure following a reported boat collision. The objective was to evaluate the structural integrity of the foundations, identify any potential damage, and confirm the safety of continued operations.
Project Execution
The inspection was performed using a Blueye Pioneer ROV equipped with high-resolution cameras and sensors, allowing a detailed assessment without diver intervention. The survey scope included close visual checks of the columns, foundations, and seabed conditions.
Key Findings
-
Structural safety confirmed: all columns and foundational elements were securely connected, with no cracks, fractures, or displacement detected.
-
Debris assessment: broken concrete fragments observed at the pier base were unrelated to the pier structure.
-
Marine growth patterns: biological coverage indicated no recent disturbance or impact.
HSE Compliance
All activities followed a strict HSE plan, including risk assessments, emergency protocols, and a controlled operational zone. The entire project was completed incident-free.
Conclusion & Recommendations
The pier was confirmed as structurally sound and safe for continued operation.
NWE recommended:
-
Routine underwater inspections after significant events,
-
Debris removal to maintain clear access around the pier,
-
Preventive measures such as installing navigational aids or protective barriers.
Closing line:
This project demonstrates NWE’s capability to deliver fast, standards-driven underwater assessments that safeguard critical marine infrastructure.
