Preliminary Survey Report: Pre-Intervention Quantitative Risk Factor Analysis for Ship Construction Processes at JEFFBOAT LLC, Jeffersonville, Indiana.

摘要

A pre-intervention quantitative risk factor analysis was performed at various shops and locations within Jeffboat LLC, a builder of river barges in Indiana, as a method to identify and quantify risk factors that workers may be exposed to in the course of their normal work duties. This survey was conducted as part of a larger project, funded through Maritech Advanced Shipbuilding Enterprise and the U.S. Navy, to develop projects to enhance the commercial viability of domestic shipyards. Four locations were identified: the rake frame subassembly process, the unloading of angle irons in the steelyard, the honeycomb confined space welding process for double hull barges, and the shear press operation in the plate shop. The application of exposure assessment techniques provided a quantitative analysis of the risk factors associated with the individual tasks. Possible engineering interventions to address these risk factors for each task are briefly discussed.
