Underwater Hull Cleaning and Propeller Polishing of MT Advantage Summer

Underwater Hull Cleaning and Propeller Polishing of MT Advantage Summer

The underwater hull cleaning and propeller polishing of MT Advantage Summer aimed to enhance the vessel’s hydrodynamic efficiency by removing marine growth and biofouling. This operation was essential in reducing fuel consumption, improving speed, and ensuring compliance with international shipping efficiency standards.

Technology Used

Hull Cleaning ROVs – Ensured thorough cleaning with minimal diver intervention. Cavitation Jet Cleaning – Used to remove stubborn biofouling with precision. Diver-Operated Polishing Systems – Achieved a high-gloss propeller finish for optimal performance.

Project Status

Completed

Project Scope

High-pressure cleaning of the hull to remove algae, barnacles, and sediments.

Propeller polishing using specialized abrasives to achieve a mirror-like finish.

Inspection and documentation of hull condition before and after cleaning.

Verification of fuel efficiency improvements post-cleaning.

Project Objective

Remove biofouling to reduce drag and fuel inefficiency.

Improve the vessel’s speed and maneuverability.

Enhance propeller performance through precision polishing.

Comply with IMO biofouling management regulations.

Challenges and Solutions

Strong Currents at Anchorage: Used high-tethered diver systems and real-time monitoring for safety.

Heavy Marine Growth on Propeller Blades: Applied graded polishing techniques for gradual removal.

Limited Operational Window Due to Traffic: Conducted cleaning during off-peak hours for efficiency.

Impacts and Outcome

Fuel efficiency improved by an estimated 5-10%.

Increased vessel speed and reduced Carbon Monoxide emissions.

Extended dry-docking intervals by maintaining hull cleanliness.
