The purpose of NSRP Project 3-96-4 was to evaluate the productivity of and areas of hydroblast (water-jetting) removal of coatings on representative areas of a ship, such as the hull, non-skid decking areas, tanks, complex geometry using open and closed loop systems. These procedures include surface cleanliness, surface contamination, coating removal rates, visual appearance, flash …

·Atlantic Marine Holding Company – (Prime Contractor) Will contribute shipyard resources and shipyard facility. · Worker fatigue induced by activities involving prolonged and repetitive use of heavy tools and equipment ·Discharge of water (process and storm water) contaminated with heavy metals into adjacent waterways and onto adjacent property via storm drains and into the ground …
Ergonomics of UHP
The project team will strive to achieve a 50% reduction in total costs associated with the UHP Water Blasting Process through industrial engineering methods, ergonomic analysis, and environmental engineering efforts. ·18 shipyards responded to survey (374 surveys mailed) ·38% of responses indicated that they use UHP Waterblasting for surface preparation ·The respondents indicated that most …
Costs of Incidents
Few safety departments have systems in place to verify these statements, however. Furthermore, companies which use verification systems that simply capture cash costs are missing a significant piece of the true incident cost puzzle. If the department does not understand an organization’s true financial loss, senior management will find it difficult to see what financial …
Partnering for the Environment
Because of the inherent types of operations, processes and some of the materials utilized in the shipbuilding and ship repair business, these facility are subject to regulatory oversight, specifically in this case, environmental regulation. Conventional stormwater management activities that are effective at other types of facilities may not necessarily be effectively implemented at a shipyard. …
Managing Shipyard Stormwater
Shipyards are facing increased regulation of stormwater discharges through the National Pollutant Discharge Elimination System (NPDES) permitting process. The development of low-cost but effective stormwater control, collection, and treatment alternatives is necessary to minimize environmental compliance costs at U.S. shipyards and strengthen the public image of shipyards as stewards of the environment. This paper presents …
Pollutants in Storm Water Discharge
[download id=”41″]Various shipyard operations and processes can be the source of pollutants found in shipyard stormwater discharges. It is important to identify the pollutant types, their potential sources and estimate the loading from these sources in order, to determine where Best Management Practices to control the discharges can be applied. This paper uses common shipyard …
Clean Water Act and Runoff
Polluted storm water runoff is a leading cause of impairment to the nearly 40 percent of the surveyed U.S. water bodies which do not currently meet water quality standards set forth by the United States Environmental Protection Agency. When left uncontrolled, this water pollution can result in a negative effect upon fish, wildlife, and aquatic …
Techniques Used in Environmental Labs
Because some analytes are light sensitive, samples must be placed in an amber container rather than a clear one. Usually, an equal volume from each of the bottles is poured into a consolidation container and then passed on to the appropriate lab for analysis. Hydrogen ion concentration (pH), for example, must be analyzed immediately whereas …
