Abstract:

What is CO2 blasting CO2 blasting is a relatively new paint removal-technology that turns liquid carbon dioxide into pellets. The most promising applications are elimination of hazardous waste, dust plumes, and contaminated water associated with the use of slag abrasives. This paper will describe the process that Naval Sea Systems Command used to take CO2 blasting from the talking stage to implementation in naval shipyards. The process started with a visit from a vendor and ended with a thirty day test of the blasting system. TEXT Navy ships bottoms are painted with antifouling paints that Contain pesticide ingredients that are used to control attachment and growth of marine animals and plants living in association with structures that are in prolonged contact with salt or fresh water. Significant growth of these fouling marine organisms, such as barnacles, seaweed, and algae, can restrict the openings of piping, increase the weight of buoys or other navigational equipment, constrict moving parts such as propellers, inhibit vessel maneuverability, and cause roughness that reduces boatship speed and increase fuel consumption. Fouling organisms may damage surface coatings, promote corrosion, interfere with sonar equipment by increasing noise levels, increase maintenance costs, and detract from the appearance of the vessel.
