Improved Welder Productivity

Project Participants: General Dynamics Electric Boat Project Start: April 2012 Welding at shipyards remains a large cost-driver in the construction of US Navy ships. This is particularly evident with the VIRGINIA class submarine (VCS), where there are hundreds of thousands of structural weld joints alone. Therefore, it is no surprise that a large focus has […]

Lead Installation Process Improvement

Project Participants: General Dynamics Electric Boat Project Start: April 2012 In support of the increased construction rates of the VIRGINIA-Class Submarine (VCS), the U.S. Navy and General Dynamics Electric Boat (GDEB) have joined forces to address costs for contractor labor, shipbuilder materials, and government furnished equipment. A goal of reducing lead installation labor hours by […]

Support of Advanced Coatings

Project Participants: General Dynamics Electric Boat Project Start: June 2011 Preservation is a significant cost driver when considering total ownership costs of Navy Ships. There is great potential to reduce additional costs associated with fleet unit repairs. This General Dynamics Electric Boat (EB) project will provide technical expertise to support an Institute for Manufacturing and […]

Measure, Layout, and Install Ship Components Using 3D Laser Scanning Tool

Project Participants: General Dynamics Electric Boat Project Start: May 2011 This General Dynamics Electric Boat (EB) project seeks to significantly reduce the labor intensive installation of ship components by implementing the use of a high speed (phase-based) 3D laser scanning tool. The 3D laser scanner is a non-contact measuring device, which eliminates expensive manual targeting […]

VCS Shipyard Material Flow Processes and Technology

Project Participants: General Dynamics Electric Boat Project Start: July 2010 Process Engineers at General Dynamics Electric Boat (GDEB) are currently executing an effort to drive down the costs associated with material flow within the VIRGINIA Class Submarine (VCS) construction facilities at its Groton and Quonset Point facilities. The two phased, 21 month project could save […]

VCS Supply Chain Manufacturing Technology Review

Project Participants: General Dynamics Electric Boat & Newport News Shipbuilding Project Start: January 2010 Contractor furnished components make up nearly 30% of the overall cost for a VIRGINIA-Class Submarine (VCS). Of that nearly $600M, $146M is attributable to the 40 most costly components. The General Dynamics Electric Boat (GDEB) and Northrop Grumman Shipbuilding-Newport News (NGSB-NN) […]

Sequencing and Scheduling

Project Participants: General Dynamics Electric Boat Project Start: May 2009 General Dynamics Electric Boat (EB) has a pressing need for improved tools to enable better planning and sequencing of the various tasks and trades involved in outfitting a VIRGINIA-Class Submarine (VCS) hull. This project developed an advanced visualization application that will provide the ability to […]

Pipe Shop Process Re-Engineering

Project Participants: General Dynamics Electric Boat Project Start: May 2009 In support of the increased construction rates of the U.S. Navy VIRGINIA-Class Submarine (VCS), General Dynamics Electric Boat’s (EB) pipe manufacturing facility has anticipated the need to double production in the near future. This project, completed in September 2011, focused on overhauling current methods, developing […]

Improved Production Engineering Management Tools

Project Participants: General Dynamics Electric Boat Project Start: April 2009 Shipbuilders are constantly striving to eliminate waste from their production processes. Often, this waste is nothing more than downtime due to an unavailable resource or a scheduling conflict. The resulting delay can jeopardize delivery dates and drive up costs associated with the labor overtime and […]

Metrology for Automated Hull Layout

Project Participants: General Dynamics Electric Boat Project Start: October 2008 The significant number of hull attachments that are fabricated and later installed on each hull contribute significantly to the cost and span time for outfitting Navy warships, particularly submarines. Each attachment or penetration may entail only a modest effort in its own right, but there […]
