One notable lean repair project that has demonstrated rapid pay- back and implementation involves the surface preparation process. Traditionally, about 25 percent of ship repair work has focused on surface prepa- ration processes, and roughly 67 percent of surface preparation work involves non- value-added activities, according to industrial engineering time studies from Atlantic Marine. Through an NSRP- sponsored Ultra-High Pressure Water Blasting (UHPWB) project. Atlantic Marine is achieving substantial process improvements and related savings in time and money. Interim statistics show a 22-28 percent reduction in total life cycle costs using Ultra-High Pressure Water Blasting on a recent destroyer project over the project's baseline — a destroyer earlier this year. Specific metrics include: • Overall process productivity — improved by more than 38 percent • Blasting gun on-time — doubled from 24 percent to 47 percent • Setup time — cut in half • Wait time — dropped from 42 percent to 19 percent • Labor per sq. ft. — 38 percent reduction • Environmental disposal cost/gallon — 94 percent reduction (expected in near term). A November demonstration in Jack- sonville showcased results to date of the project to U.S. shipyards as a means of quickly transferring this knowledge throughout the U.S. industry. The ship- yard compared statistics from similar water blasting jobs on two sister war- ships, the USS Spruance (DD-963) and the USS Obannon (DD-987). The Spru- ance underwent interim dry-docking availability a year ago when the project was just getting underway, which result- ed in some substantial man-hour overruns for the surface prep process. "This project has had a significant impact on increasing our competitive position in the surface preparation process of military and commercial ship repair." said Ed Fleming, president of Atlantic Dry Dock Corp. in Jacksonville. "It has allowed Atlantic Dry Dock to compete with the more efficient dry blasting operations while reaping the environmental benefits of water blast- ing." Contributing to the overall success of the hull blasting and painting effort on Obannon was the "lean" detailed plan the workers followed to prepare, blast and paint continuously from bow to stern with minimal delays and interruptions. Given the significance of surface prepa- ration and coating in many interim dock- ing schedules, these time reductions have the potential to directly reduce time in dock and thus return the warship asset to the deployment-ready status more quick- iy. Ergonomic improvements include a "Gun Rack" to support the blasting gun that takes the stress off the worker, and a "Crawler" that supports the worker in reclined positions and can be adjusted in many different angles. As part of the UHPWB project, Atlantic Marine is also tackling the environmental protection costs associated with surface preparation. To reduce the cost of disposing of conta- minated blasting water, the team assessed options and selected the Electro-Pulse System to remove "metals" which remain after primary cascade sedimentation has been accomplished.
