Outfitting Process Improvement

Project Participants: General Dynamics Electric Boat Project Start: June 2007 Reducing VIRGINIA-Class Submarine (VCS) construction costs to $2B and cycle time to 60-months are the primary goals to increasing acquisition and maintaining the submarine industrial base. With the VCS design essentially complete and the bulk of the construction work ahead, one of the greatest opportunities […]

Design for Production 0- Process Improvement

Project Participants: General Dynamics Electric Boat Project Start: April 2007 Electric Boat Corporation assessed and evaluated a new methodology utilizing “design for production” (DfP) process improvement techniques at their ship construction facilities in Groton, CT and Quonset Point, RI. This project targeted three key areas of the DfP process: cost-based design, design standards/rules, and seamless […]

Laser Image Projection

Project Participants: General Dynamics Electric Boat Project Start: January 2007 General Dynamics Electric Boat (EB) successfully piloted a new laser imaging system that enables their Quonset Point facility to automate the layout of attachments during early outfitting stages of VIRGINIA-Class Submarine (VCS) construction. The project team used an innovative laser image projection system to locate […]

Internal Supply Chain

Project Participants: Marinette Marine Corporation Project Start: December 2006 Marinette Marine Corporation (MMC), a subsidiary of The Manitowoc Company Inc., is currently designing and building vessels for the U.S. Navy, the U.S. Coast Guard and commercial customers. The U.S. Navy work includes construction of the first Littoral Combat Ship (LCS) and the Improved Navy Lighterage […]

Computed Radiography Alternative to Conventional Film

Project Participants: General Dynamics Electric Boat Project Start: February 2006 Conventional film radiography has been used for volumetric inspection of piping and structural welds, castings and various components used for construction, overhaul and repair of naval surface vessels and submarines and for more than fifty years. Computed radiography technology advancements promise to revolutionize industrial radiography […]

Nested Material Manufacturing Technology Improvement

Project Participants: National Steel and Shipbuilding Company (NASSCO) Project Start: February 2006 As shipyards struggle to improve fabrication process efficiency, especially pipe fabrication, there is increased reliance on automated fabrication machines and processes. Planning and routing decisions, whether manual or automated must account for variables in individual process times, work station capacities, emerging engineering design […]

Thermal Tensioning of Thin Steel Ship Panel Structures

Project Participants: Northrop Grumman Shipbuilding Project Start: June 2005 Several current U.S. Navy construction programs are experiencing high rates of distortion and buckling on thin steel structures. The standard shipyard practice of fabricating stiffened steel panels by arc welding causes heat-induced buckling and angular distortion. Correcting the distortion is a necessary but time-consuming operation that […]

Re-engineering the Internal Supply Chain/Material Delivery Process

Project Participants: Northrop Grumman Shipbuilding Project Start: November 2004 Misplacement or loss of material and data in a ship-focused organization can create considerable disruption in the workflow. The details of where the material/data is needed and when needed are critical to the successful completion of the vessel and to control construction costs. Misplaced material can […]
