A pre-intervention quantitative risk factor analysis was performed at various shops and locations within Marinette Marine, as a method to identify and quantify ergonomic 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 the Maritech Advanced Shipbuilding Enterprise and the U.S. Navy, to develop projects to enhance the commercial viability of domestic shipyards. The application of exposure assessment techniques provided a quantitative analysis of the risk factors associated with the individual tasks. Based on these analyses, four ergonomic interventions are suggested for Marinette Marine: 1) wheeled, adjustable work stools and knee supports for engine room and lifeboat rack welders, torch cutters, and grinders, 2) a rotating/tilting weld positioner for the tripod assembly welding process 3) worker awareness training in the sheetmetal shop and 4) come-alongs requiring the lowest maximum pull for a given capacity, with capacity appropriate to the shipfitting tasks performed. Of these interventions, it is expected that the wheeled, adjustable work stools/ knee supports and the rotating/ tilting weld positioner will have the most effective impact on reducing musculoskeletal injuries, and therefore they are the most strongly recommended changes. Detailed descriptions of each intervention are provided including cost benefit analysis where appropriate.
