CLASS UNDERWATER INSPECTION OF MT ELI AKASO AT BONNY OFFSHORE

CLASS UNDERWATER INSPECTION OF MT ELI AKASO AT BONNY OFFSHORE

A comprehensive underwater inspection was carried out on MT ELI AKASO at Bonny Offshore to assess the vessel’s structural integrity and ensure compliance with classification society requirements. This inspection was crucial for maintaining the vessel's seaworthiness, detecting potential issues, and obtaining necessary certification for continued operation.

Technology Used

Remote Operated Vehicles (ROVs) – Used for high-resolution video inspections. Ultrasonic Thickness Gauging (UTG) – To measure steel thickness and detect corrosion. Magnetic Particle Inspection (MPI) – For identifying cracks and material defects. High-Definition Underwater Cameras – To capture evidence for class approval.

Project Status

Completed

Project Scope

Hull Inspection: Visual and ultrasonic assessment of plating and weld seams.

Propeller & Rudder Examination: Checking for cavitation, misalignment, or damage.

Sea Chest & Anodes Inspection: Verifying the condition of sea valves and cathodic protection systems.

Underwater Video & Photography: Documenting findings for class verification.

Project Objective

Conduct a detailed underwater survey to assess the hull’s condition.

Identify and document potential structural defects, marine growth, or damage.

Ensure compliance with class society regulations for vessel certification.

Provide recommendations for any necessary repairs or maintenance.

Challenges and Solutions

Tidal and Currents Interference: Scheduled dives at optimal tidal windows for better stability.

Marine Growth Accumulation: Deployed specialized cleaning tools for clear assessment.

Impacts and Outcome

Achieved full compliance with class society standards.

Identified and addressed potential structural concerns, ensuring vessel safety.

Facilitated smooth certification renewal for continued operations.
