Naval Shipyards at Pearl Harbor, Portsmouth, New Hampshire, Norfolk and Bremerton
Naval public shipyards are the sole provider of nuclear depot-level maintenance and fueling for the Navy’s fleet. As such, it is critical for the shipyards to deliver vessels on time back to the
operating forces. Inefficient layout of shipyard infrastructure, aging facilities and equipment, antiquated network infrastructures, and inadequate facility configuration constrain how work is accomplished creating sub-optimized conditions for the flow of work at naval shipyards.
The Naval Shipyard Infrastructure Optimization I Plan (NSIOP) Phase I presents an unconstrained, optimal facility layout of the four public naval shipyards—Pearl Harbor Naval Shipyard and
Intermediate Maintenance Facility, Portsmouth Naval Shipyard, Norfolk Naval Shipyard, and Puget Sound Naval Shipyard and Intermediate Maintenance Facility—that reduces transportation and movement of personnel, material, and ship components to increase operational efficiencies and reduce costs.
HHF utilized two planning analyses to inform the development of an optimal facility layout: process flow analysis and zone analysis. Through a data-driven analysis of industrial process flows, existing inefficiencies in transportation and motion during the course of specific maintenance availabilities were identified. A zone-based planning framework was used to analyze the location of existing functions and identify optimal locations for shipyard functions. HHF developed a facility program to site notional building footprint plans and calculated rough order-of-magnitude construction costs. Based on the notional footprint plans, HHF mapped optimal process flows to quantify the reduction in distance between current and optimal facility locations that increase operational efficiencies and realize a substantial return on investment for the Navy.
HHF engaged stakeholders throughout the development of the plan. Workshops were conducted to defineprocess flow methodology, optimized planning concepts, and return on investment metrics. Site visits were used to collect data, interview subject matter experts, confirm current state process flows, present the planning framework, and create an optimal notional plan. Ultimately, the findings of the NSIOP Phase I were incorporated into a comprehensive Report to Congress that addresses the infrastructure deficiencies at the public naval shipyards.
