Abstract:

One of the projects sponsored by the MARITECH Advanced Shipbuilding Enterprise Initiative in 1999 is being conducted jointly by the Atlantic Marine Holding Company (AMHC) in Mobile, Alabama, (which also has facilities in Jacksonville, Florida) and the Manufacturing Engineering Laboratory of the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. this project, "Knowledge-Based Modular Repair: Advanced Technology Applications for Ship Repair and Conversion," has the following goal: to reduce cycle times and costs, and improve the precision and overall qualilty of repair and conversion processes conducted by American shipyards. This paper presents the work being conducted in this project, along with first year results. The project is incorporating precision metrology techniques and advanced modeling and simulation technologies into repair and conversion operations. The project is facilitating prefabrication and modular installation of structural and mechanical system components during large-scale overhaul and conversion projects by the use of advanced engineering technologies combined with reverse engineering and accurate, predictive modeling tools. Planning processes are being created to incorporate the technologies developed by the project into contracted work in the shipyard and to assist the customer in making informed, accurate decisions about optimum approaches to real-world projects.
