Modular Outfitting/Packaged Units
Project Participants: Huntington Ingalls Industries, Inc.
Project Start: September 2014
Legacy designs, such as LHA/LHD and DDG 51, date back several decades and have not had the opportunity to invest in an optimized build strategy. The current build approach for congested spaces such as machinery rooms, fan rooms, pump rooms, elevators, and other specialized spaces/equipment is cumbersome. Often times these spaces are outfitted very late in the build schedule (during erection or post launch) where accessibility is limited and demand on support services is higher, making outfitting activities of these spaces more difficult and costly. A reliable, cost effective process/tool to determine where the opportunities exist and the potential savings is needed to assess current build strategy approaches.
The Modular Outfitting project is focused on providing a reliable, cost effective tool that will assist in identifying opportunities and savings for alternate build strategies. Significant opportunities exists to “pre-package/test” large portions of the ship but often times the projected cost of the changes prevents the program offices from seriously considering the change. The build strategy (build sequence, configurations, make/buy, testing etc.) of these spaces could be modified using a modular outfitting approach which could result in significant cost savings.
The Modular Outfitting Project will develop and demonstrate, through actual examples, a build strategy assessment tool/process. The goal will be to standardize the methodology for evaluating/changing the current build strategy approach for a ship program. The build sequences of outfitting activities will be examined in detail to identify possible changes that could result in cost savings. Changes to design may also be identified and proposed that would result in additional cost savings however that will not be the main focus of this project.
The Ingalls project has two phases, with Phase I identifying opportunities for modularity and conducting an impact assessment and Phase II developing and demonstrating a build strategy tool/process and pilot testing for validation. To support implementation, Ingalls will deploy the solution in its target environment after initial acceptance tests are complete, and engage end users to ensure the solution satisfies documented needs and expectations. Once implemented, HII-Ingalls anticipates this effort will reduce labor hours for current activities with an estimated cost savings of $2.3M per LHA hull.
