Project Scope

The scope of work included:

Visual Inspection: Conducted by expert divers and remotely operated vehicles (ROVs) to examine the buoy structure, anchor chains, and piping.

Non-Destructive Testing (NDT): Utilizing ultrasonic thickness gauging, magnetic particle inspection, and cathodic protection system evaluation.

Marine Growth Removal: Cleaning of biofouling to enable accurate assessment.

Leak and Corrosion Assessment: Checking for structural degradation and potential failure points.

Reporting & Recommendations: A detailed report with findings, risk assessments, and recommended maintenance actions.

Project Objective

The primary objectives of this inspection were:

To evaluate the overall condition of the SBM and its components.

To detect structural weaknesses, corrosion, or marine growth that could impact performance.

To ensure compliance with international safety and environmental regulations.

To provide recommendations for preventive maintenance and repairs.

Challenges and Solutions

Harsh Marine Conditions: Strong currents and poor visibility were mitigated using advanced sonar imaging and high-powered ROV lighting systems.

Biofouling & Marine Growth: High-pressure water jets and manual cleaning techniques were used to remove accumulated debris.

Limited Downtime for Inspection: A well-coordinated plan minimized disruptions to SBM operations, ensuring efficiency.

Impacts and Outcome

ROVs & Diver Inspections – For high-resolution imaging and close-up assessments.

Ultrasonic & Magnetic Testing – To detect corrosion and structural weaknesses.

3D Sonar Mapping – For digital modeling of the SBM.

Biofouling Removal – High-pressure water jets for cleaning.
