Mitsui O.S.K. Lines (MOL) and its partners have successfully tested a groundbreaking laser-based rust removal technology, known as the "InfraLaser" system, on a vessel’s outer hull. This innovative approach promises to enhance ship maintenance efficiency while significantly reducing environmental impact.
Key Takeaways
- Innovative Technology: The InfraLaser system aims to replace traditional sandblasting methods.
- Environmental Benefits: The laser method minimizes dust, noise, and waste, leading to reduced pollution.
- Improved Safety: The technology enhances occupational safety for workers involved in ship maintenance.
- Collaborative Development: The project involved MOL, MOL Drybulk, Furukawa Electric, and TSUNEISHI Shipbuilding.
The Need for Change in Ship Maintenance
Ship maintenance is crucial for ensuring the longevity and safety of vessels. Traditionally, rust and coatings are removed using sandblasting, which involves abrasive materials that can create significant debris and pollution. This method not only requires extensive cleanup but also poses health risks to workers due to the inhalation of dust and exposure to hazardous materials.
The InfraLaser System
The InfraLaser system represents a significant advancement in ship maintenance technology. Developed through a collaboration that began in 2021, this laser-based approach offers several advantages:
- Minimal Environmental Impact: Unlike sandblasting, the laser method produces minimal dust and waste, reducing the environmental footprint of ship maintenance.
- Enhanced Safety: The technology operates with zero reaction force, eliminating recoil and making the process smoother and safer for operators.
- Efficiency: The system is designed to streamline the rust and coating removal process, potentially leading to faster turnaround times for ship repairs.
Collaborative Efforts and Testing
The successful trial of the InfraLaser system was conducted in December 2024 on an MOL-operated vessel, utilizing outer hull paint supplied by Kansai Paint Marine. The collaboration involved:
- Furukawa Electric: Leveraging expertise in metal processing to optimize laser conditions for effective rust and paint removal.
- TSUNEISHI Shipbuilding: Providing insights from shipbuilding and repair to refine the technology.
- MOL and MOL Drybulk: Offering operational feedback to ensure the system meets real-world needs.
Future Prospects
Following the successful trial, MOL and its partners are committed to expediting the development of the InfraLaser system as a viable alternative to traditional sandblasting. The focus will be on:
- Automation: Integrating automation into the rust removal process to further enhance efficiency.
- Labor-Saving Innovations: Reducing the manpower required for ship maintenance tasks.
As the maritime industry continues to seek sustainable solutions, the InfraLaser system stands out as a promising advancement that aligns with environmental goals while improving operational safety and efficiency in ship maintenance.
