Revolutionizing Marine Maintenance with Laser Cleaning
Cleaning With Light: A New Era for Ship Maintenance
The Cost of Corrosion
Corrosion removal has been among the heaviest and most expensive tasks for both military and civilian ship maintenance technicians. A 2022 audit by the Department of Defense showed that between 2017 and 2020, corrosion maintenance conducted by Naval Air squadron maintainers on F/A-18C-G aircraft alone cost the Navy more than $2 billion. This figure does not include the costs of treating corrosion in the Navy’s many other aircraft and ships in service. Various estimates place this figure at approximately $3 billion annually. Cleaning vessels used in commercial shipping and fishing, ferries, cruises, and luxury vessels generate equally substantial costs.
Old Versus New: Traditional Methods vs. Laser Cleaning
Traditional methods of corrosion removal and surface preparation can be both time-consuming and costly. But there is a solution to make the process more efficient, cost-effective, and environmentally friendly: MARLIN laser cleaning technology from Laser Photonics Corporation (LPC).
Traditional Methods:
- Handheld power tools (needle guns, grinding wheels, wire wheels)
- Sandblasting, dry ice blasting, high-pressure water jetting, and chemical cleaning
- Labor-intensive, polluting, and damaging the underlying material
- Require expensive consumables and substantial time for preparation and cleanup
- Cannot be automated, but rather require on-the-fly adjustments to handle complex tasks and avoid damage
- Draw scrutiny from regulators like the EPA and OSHA due to risks to applicators and the environment
- Not feasible for many interior and exterior applications
Marlin Laser Cleaning:
- Uses the thermal energy of laser light pulses
- Energy controllably blasts off the contaminant, vaporizing part or all of it
- Extreme precision achieved by manipulating output power, pulse length, beam pattern, and exposure
- Suitable for rapid or deep corrosion removal or removing thin layers of coating without damaging the base
- Surface ready to recoat without further preparation
- More efficient and effective in treating surfaces compared to handheld tools
- Selectivity in removing coating layers of various thicknesses and versatility in accessing areas handheld tools cannot reach
- Versatility in application and range of material, with the additional benefit of cleaning equipment and tools
Shipbuilding Industry: Cost & Efficiency
The Problem Is Big
Many hours are spent assessing compromised surfaces for corrosion, prepping surfaces for paint adhesion, and coating surfaces with fresh paint or other finish. While the cost of laser-cleaning technologies can be steep, the production efficiency (fewer worker hours) and reduced spending on consumables, cleanup, and disposal of hazardous waste more than balance the scales.Business economics, labor reductions, training cutbacks, shortened shipyard availabilities, and diminished waterfront/intermediate maintenance capacity all contribute to the growing need for the new and better maintenance approaches delivered with technologies such as the MARLIN systems.
Importance of Shipbuilding
Critical Applications
- Material processing with laser equipment produces cleaner marine steel surfaces, leading to better results in coating, welding, and other processes.
- Treating metal surfaces to eliminate corrosion, saltwater stains, biological growth, and other contaminants is key for maintaining components like engines, generators, fuel pumps, winches, anchoring chains, water separators, latches, door hinges, locks and gear shifting and throttle mechanisms without disassembly.
- Proper treatment helps preserve functionality and longevity, prevents further corrosion and deterioration, and reduces the risk of premature failure.
- Cleaning hulls and underwater components and removing marine organisms without toxic antifouling paints improves fuel efficiency and reduces drag without introducing contaminants into the environment.
- Laser cleaning generates minimal particulate dust, which can be quickly cleaned with a filtered fume extractor.
- Laser tools are suitable for integration into automated operations.
