Design for Production 3- Design Alternatives

Project Participants: General Dynamics Electric Boat Project Start: February 2008 Recent studies have concluded that Design for Production (DfP) is the single most influential factor to reduce ship production cycle time and costs, as ship design processes are not keeping pace with state-of-the-art manufacturing practices. The production workforce must receive timely, accurate, configuration-managed, electronic data […]

Design for Production 1- Knowledge Tools

Project Participants: General Dynamics Electric Boat Project Start: October 2007 Recent studies have concluded that Design for Production (DfP) is the single most influential factor to reduce ship production cycle time and costs, as ship design processes are not keeping pace with manufacturing practices. Although design of the VIRGINIA-Class Submarine (VCS) is essentially complete, there […]

Design for Production 2- Seamless Delivery 3-D Product Model

Project Participants: General Dynamics Electric Boat Project Start: October 2007 Recent DOD studies have concluded that Design for Production (DfP) is the single most influential factor to reduce ship production cycle time and costs, as ship design processes are not keeping pace with manufacturing practices. This project will use previously developed DfP elements to develop […]

Small Weldment Optimized Cell

Project Participants: Northrop Grumman Shipbuilding-Newport News Project Start: August 2007 Small weldments at Northrop Grumman Shipbuilding-Newport News (NGSB-NN) are considered any structural part manufactured or assembled in the small component fabrication and assembly shops (generally up to 4-ft by 8-ft and weighing no more than 5 tons). Current manufacturing and assembly methods for small weldments […]

VCS Material Management

Project Participants: General Dynamics Electric Boat Project Start: July 2007 Material flow, from requirement identification to delivery to the trades and into work-in-process for consumption at large shipyards is difficult to manage. Current practices frequently result in high cycle times, excess inventory, material availability rates that are lower than desired, and unacceptable levels of lost […]

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 […]

Weld Distortion Prediction Software for Submarine Construction

Project Participants: General Dynamics Electric Boat Project Start: November 2004 The costs required to effectively deal with weld distortion and/or correct the resulting negative effects are significant during submarine construction. Weld distortion impacts the fabrication costs of all welded parts, however, the larger the structure, the greater the impact on construction schedule. What are absent […]

Ultralight Pulse Gas Metal Arc Welding for Shipyard Applications

Project Participants: General Dynamics Electric Boat Project Start: June 2004 Set-up costs associated with welding operations that support unit erection and outfitting represent a significant portion of overall shipbuilding costs. For small welding jobs such as hanger and tack welding, the labor associated with equipment relocation and setup can be a large part of the […]
