The purpose of NSRP Project 3-96-4 was to evaluate the productivity of and areas of hydroblast water-jetting removal of coating on representative area the hull non-skid decking areas, tanks, complex geometry using open and closed loop systems. The objective of this multi-task, 24-month project was to compile supporting information regarding productivity data. During this study various tasks were undertaken and completed a brief description of each task follows. During this project a review of current literature on water-jetting, and surveys to shipyard industries was performed. The literature search was performed in publications dedicated to the painting industry. This was done to determine a baseline of what to expect in the shipyard industry. The next stage was to canvass public and private shipyards in the United States to determine if they were currently using water-jetting to remove coatings. Shipyards which stated that they perform water-jetting at their yard were sent a survey with an enclosed postage paid envelope to facilitate the prompt return of the survey. The surveys provided information on the types of equipment used types of vessels and coating systems water-jetted production rates removal specifications down-time, manning levels, and how they dealt with flash rusting. Another aspect of this project was to identify ships suitable for the project study. As ships operational and repair schedules are constantly changing this was an ongoing process throughout the study. Shipyards which stated that they did use water- jetting during our initial canvassing were regularly contacted for upcoming work in order to schedule on-site inspections. Water-jetting contractors were also contacted to advise us of their upcoming work so that we could schedule on-site visits.
