LNG Tanker Propeller Polishing Thailand – A+ Grade (Rubert Scale)

LNG Tanker Propeller Polishing Thailand – Project Overview

MaxiDive Co., Ltd. successfully completed LNG tanker propeller polishing Thailand operations at Map Ta Phut Anchorage. The vessel (LOA 300M) required polishing of two propellers to achieve A+ grade (Rubert’s Scale), ensuring optimal hydrodynamic performance.

All works were executed by ISO-certified, class-approved commercial diving teams, similar to our Underwater Hull Cleaning Thailand services.

Scope of Work – A+ Grade Propeller Polishing

The project included:

• Underwater inspection of both propellers

• Surface preparation and fouling removal

• Precision polishing to A+ grade (Rubert’s Scale)

• Final visual verification via real-time CCTV inspection, aligned with UWILD Inspection Services

The polishing process restored blade surface smoothness, reducing resistance and improving propulsion efficiency.

Operational Execution at Map Ta Phut Anchorage

Operations were conducted at Map Ta Phut Anchorage, Thailand, a high-traffic LNG logistics zone requiring strict coordination and safety compliance.

Key execution factors:

• Deployment of certified commercial diving team

• Use of professional polishing equipment

• Continuous monitoring via real-time CCTV inspection

• Compliance with class-approved procedures

All works were completed without disruption to vessel schedule. In case of urgent requirements, similar operations can be supported via Emergency Underwater Repair.

Results – Performance & Efficiency Gains

Achieving A+ grade polishing delivers:

• Reduced fuel consumption

• Improved vessel speed performance

• Lower emissions

• Extended drydock intervals

For LNG carriers, maintaining propeller condition is critical due to operational efficiency requirements and fuel cost sensitivity.
