Delivering the foundation of fleet readiness

2023 Shipyard Infrastructure Optimization Program’s (SIOP) Major Accomplishments

SIOP has $6.5 billion under construction, including four dry docks at three of the four naval shipyards.  Thirty projects ($867M) have been completed and 165 pieces ($399M) of industrial plant equipment delivered.

The completed digital twin at Pearl Harbor Naval Shipyard (PHNS) is being used to support scenario analysis and course of action (COA) development. The future evolution of the digital twin to the equipment level will enable additional optimization of maintenance processes at the facility level to inform project development, facility design and capital equipment modernization requirements.    

SIOP’s North Star:
Enable increased nuclear-fleet maintenance throughput by recapitalizing shipyard infrastructure and equipment required to conduct scheduled depot maintenance and by reconfiguring infrastructure layout to deliver reductions in availability durations.

The accomplishments below highlight significant progress in infrastructure recapitalization and enhancement across the Navy’s four public shipyards, advancing SIOP’s goals of improving maintenance throughput and operational efficiency for the Navy's nuclear fleet.


  • Commenced second phase of industrial modeling for each shipyard.

    • Norfolk Naval Shipyard (NNSY), Portsmouth, Va.

    • Pearl Harbor Naval Shipyard (PHNS), Pearl Harbor, Hawaii.

    • Portsmouth Naval Shipyard (PNSY), Kittery, Maine.

    • Puget Sound Naval Shipyard (PSNS), Bremerton, Wash.

  • Awarded Area Development Plans (ADPs) for NNSY and PNSY; previously awarded for the other two shipyards.

  • Completed Environmental Impact Statement for PHNS Dry Dock 5 and Waterfront Production Facility (WPF).

  • Initiated planning studies for WPFs at PHNS, PSNS, and NNSY.

  • Completed rapid seismic assessments of PHNS Dry Docks 1-4.

  • Completed comprehensive seismic analysis of PSNS Dry Dock 6.

  • Completed rapid seismic assessments of PSNS Dry Docks 1-5.

  • Completed equipment standardization selection for Shop 31.

  • Conducted material RFID tagging pilot at NNSY.

Design & Construction

  • Started construction of PHNS Dry Dock 5.

  • Completed electrical upgrades for PSNS Dry Dock 4 and Pier 3.

  • Implemented Survivability Flooding Protection for Dry Docks 2-4 at NNSY.

  • Completed restoration of NNSY Dry Dock 4.

  • Initiated upgrades for NNSY Dry Dock 8 (cooling, berths, caisson).

  • Completed portal crane rail upgrade for PNSY Dry Dock 2.

  • Restored Communications Center at PNSY.

The prioritization of dry dock re-capitalizations continues, aiming to accommodate upcoming platforms. This necessity arises from the requirement to accommodate the size and configuration of future force platforms, including the USS Ford class aircraft carriers, and future versions of the USS Virginia and USS Columbia class submarines. Each dry dock's re-capitalization is scheduled to align with availability dates for these platforms. In conjunction with dry dock upgrades, the optimization and equipment re-capitalization components of SIOP are crucial. They aim to shorten maintenance and modernization timelines and enhance operational readiness of these platforms to meet fleet demands.

The Navy's four public shipyards perform a vital role in national defense by maintaining the nuclear-powered fleet in order to provide combat-ready ships. Originally built in the 19th and 20th centuries to build sail- and conventionally-powered ships, the Navy's public shipyards are not efficiently configured to maintain and modernize nuclear-powered aircraft carriers and submarines. With the Navy's needed focus on operations, the aging shipyards have been unable to adequately sustain and optimize their facilities, utilities, dry docks, equipment and information technology infrastructure. These inefficiencies and obsolete facilities result in higher maintenance costs, schedule risks and reliability issues.  
To create the shipyards that our Nation needs requires making significant investments to modernize dry docks, optimize industrial processes and modernize standard equipment to bring these critical industrial sites to modern standards.

The Navy established the SIOP program office in May 2018. SIOP is a centrally-managed program led by Naval Facilities Engineering Systems Command (NAVFAC) with support from Naval Sea Systems Command (NAVSEA) and Commander, Naval Installations Command (CNIC).  NAVSEA is the operating agent and the technical authority for all four shipyards, executing the capital equipment program while NAVFAC provides facilities engineering and construction programs, supports environmental and compliance requirements and retains head-of-contracting-activity authority for facilities and dry dock investments. CNIC is the Navy's shore integrator and directs the Navy's shore environmental program.

The Navy will ensure that the optimization process fully integrates environmental considerations including natural and cultural resources, water and air quality, and more. During the planning for each shipyard, the Navy will develop alternatives for assessment under the National Environmental Policy Act (NEPA), Endangered Species Act (ESA) and the National Historic Preservation Act (NHPA). The Navy will work with stakeholders as part of the decision-making process and will conduct all appropriate NEPA, natural resource and NHPA analyses; agency and government-to-government consultations and public engagement and obtain all required permits to ensure a proactive approach to environmental protection.

Shipyard Infrastructure Optimization Program (SIOP) Industry Day

The Program Executive Industrial Infrastructure (PEO II) and Naval Facilities Engineering Systems Command (NAVFAC) are organizing a two-part SIOP Industry Day aimed at enhancing the efficiency and effectiveness of the SIOP initiative across the Navy's four public shipyards: Pearl Harbor Naval Shipyard (PHNS), Puget Sound Naval Shipyard (PSNS), Norfolk Naval Shipyard (NNSY), and Portsmouth Naval Shipyard (PNSY). The objective is to integrate best commercial practices, innovative government approaches, advanced materials, and technologies to improve program cost, schedule, and performance metrics.

The Shipyard Infrastructure Optimization Program (SIOP) mission is to execute the Navy’s once-in-a-century investment to reconfigure, modernize and optimize our four aging naval shipyards into new modern facilities that will serve our Nation into the future.

In September 2021, the Department of the Navy updated SIOP’s reporting relationships to ensure disciplined and synchronized execution of the multiple major construction efforts managed within SIOP and designated Naval Facilities Engineering Systems Command as the single, responsible executive lead for execution of SIOP and established the Program Executive Office Industrial Infrastructure (PEO II) to oversee the Program Management Office-555 (PMO-555) SIOP.

  • The Navy’s four public shipyards – Norfolk Naval Shipyard (NNSY), Portsmouth Naval Shipyard (PNSY), Puget Sound Naval Shipyard and Intermediate Maintenance Facility (PSNS & IMF), and Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNS & IMF) – are essential elements of our national defense.
  • The Navy's four public shipyards need substantial recapitalization and reconfiguration in order to improve the timely return of ships and submarines to the fleet following maintenance and modernization.
  • Completing ship and submarine maintenance availabilities on time and getting them back to the fleet is vital to ensuring the United States maintains its maritime dominance. 
  • The Navy is investing heavily in shipyard infrastructure. SIOP will construct and recapitalize dry docks, recapitalize and reconfigure infrastructure, and modernize industrial plant equipment.
Shipyard Infrastructure Optimization Program Q&A:
An Interview with Capt. Luke Greene, PMO-555, on the Importance of Shipyard Modernization

Story by Michael D. Brayshaw, Norfolk Naval Shipyard  

sharethis sharing button

PORTSMOUTH, Va. (Dec. 1, 2023) - Norfolk Naval Shipyard (NNSY) Public Affairs recently had an opportunity to meet with Capt. Luke Greene, Program Manager for Program Management Office-555 (PMO) supporting the Shipyard Infrastructure Optimization Program (SIOP). Via SIOP, the Navy is making substantial investments across the four public shipyards through the construction and modernization of dry docks, other infrastructure and modernized industrial plant equipment. The results of this effort are being seen at NNSY with upgraded facilities such as Dry Dock 4, which had a $191 million renovation completed earlier this year. While NNSY has had an important past over its 256-year history, PMO-555 leaders like Capt. Greene are at the forefront of ensuring a vital future at America’s Shipyard supporting the 21st century Navy.

Q: What is your role in SIOP?

Capt. Greene: As the Program Manager, I lead a team that’s going to bring recapitalization effort to all four shipyards. Recapitalization includes facilities and equipment, and its focus is to bring new capability or restore capability for the shipyards in order to increase maintenance throughput.

Q: Specifically, what is the overall intent of visiting Norfolk Naval Shipyard?

Capt. Greene: Two things, primarily. One is, as a civil engineer, I do always love to come down and see the projects—that’s my bread and butter. An opportunity to see the projects at the ground level as well as the conditions around the shipyard that the program will restore. With the projects specifically going on, there’s Dry Dock 8 [undergoing renovation], and we also visited Dry Dock 4, where we we’ll do the Reactor Servicing Complex. The other half, and a major component of our program, is equipment recapitalization and meeting with the team that really delivers on equipment.

Q: What do you see as being the specific mission of SIOP and its ultimate goal?

Capt. Greene: The ultimate goal is all about Fleet readiness. We are enabling the team here at the shipyard, giving them the best tools and opportunities to be able to turn ships around on time. Our mission is to deliver condition, capacity and configuration in the facilities—in some cases we’ll deliver new facilities, in some cases we’ll recapitalize older facilities. All of that is with a focus on increasing that maintenance throughput.

Q: How do you think SIOP is going to benefit not only NNSY meeting its mission, but also quality of work life for employees?

Capt. Greene: Quality of service is a major component of this program. As we lay out and assess the best optimized shipyard, we account for things that impact people’s day-to-day experience. We account for break rooms, travel distance and parking. The overall condition of the facilities you work in is a major component of your daily experience. If you work in a modern, upgraded facility, it’s a very different experience that shows we value you.

Q: Are there any specific SIOP projects at NNSY you’d like to discuss?

Capt. Greene: Certainly the dry docks. The dry docks are a foundational building block for the shipyards; we focus heavily on those and build everything from that foundation. The work going on at Dry Dock 8 to support Ford-class carriers is a complex, interlinked series of projects that requires close coordination between [NNSY SIOP Department Director Gary Dion-Bernier] and his team. The [adjacent] Berth 40/41 project is a perfect example of why we have to have the best people on the ground managing these projects. There’s still a lot of work and coordination to do with that project, but we’ve got the right people on that team.

Q: Mark Edelson, Program Executive Officer for Industrial Infrastructure, said that for the shipyards, “the task at hand is to bring vital infrastructure that is centuries-old into the modern era.” How do you feel PMO-555 is most effectively meeting that task?

Capt. Greene: This is a problem that has existed at the shipyards and across all Navy infrastructure for quite a while. We are taking a different approach with a more holistic look at the shipyards so that we can really focus on delivering capability versus taking a project-by-project approach. The perfect example right there is building out the area development plan for each shipyard which lays out the long-range plan to deliver those capabilities.

Q: There are obviously some challenges with updating vital infrastructure at the shipyards. How is PMO-555 working to effectively mitigate those?

Capt. Greene: It’s a team effort. PMO-555 is certainly at the crux of the program, but we rely heavily on each of the shipyards as the end operator. We rely on their inputs for long-term solutions. And then of course, we rely heavily on NAVFAC in providing some of the facilities and infrastructure solutions. Beyond a holistic plan, it’s really corralling a team in a way of aligning everybody on the same goals. With the program’s complexity and number of stakeholders who all have a very valid, vested interest in its success, it really is a team effort.

Q: Can you give some perspective on the PMO-555 involvement in the Navy’s Chief Digital Transformation Office efforts at the shipyard?

Capt. Greene: A part of this program on the digital side is twofold. One is looking at the equipment we provide and opportunities to connect it and maximize the capabilities that equipment brings. We have a lot of modern technologies available, and frankly we’re leaving some of those capabilities on the table because we cannot connect it. Another that’s very near and dear to the mechanics’ day-to-day experience is the ability to locate components and materials when they need them. We’re introducing a Naval Autonomous Data Collection System which helps with that asset visibility and helps shipyard employees locate those components and materials. On the digital side, the final thing I would highlight is building out a digital process model. The model lays out the most optimized shop floor in future buildings as we recapitalize or deliver new facilities. It’s an enormous benefit to the shipyard workforce because it allows them in real time to evaluate and streamline their processes. It’ll be a continuous adjustment as you identify choke points to continually improve. Delivering that model will be a big benefit for the shipyard.

Editor’s Note: SIOP is a holistic plan that integrates all infrastructure and industrial plant equipment investments at the Navy’s four public shipyards to meet nuclear fleet maintenance requirements, as well as improve Navy maintenance capabilities by expanding shipyard capacity and optimizing shipyard configuration.

Q1:  In practical terms, why was it necessary to establish the Program Executive Office Industrial Infrastructure (PEO II) over the existing Program Management Office 555 (PMO 555) Shipyard Infrastructure Optimization Program (SIOP)?

A1:  The standup of PEO II ensures that SIOP’s once-in-a-century recapitalization effort has the necessary discipline and synchronization in defining and executing the multiple major construction efforts within the program while maintaining uninterrupted support to the fleet.  PEO II was established as a NAVFAC-affiliated PEO. PEO II and the PMO 555 SIOP are implementing agile acquisition methodologies to coordinate the programmatic execution of this complex effort.  PEO II also remains integrated with the Naval Sustainment System – Shipyards (NSS-SY) efforts as the lead for the NSS-SY Infrastructure Pillar. NSS-SY is the Navy’s enterprise approach to identify and execute initiatives that improve shipyard operations to increase capacity with more efficient maintenance throughput for nuclear ships and submarines.


Q2:  The initial 2018 Report to Congress projected SIOP as a $21-billion, 20-year program. What is today’s estimate? 

A2:  Numerous information points and learning tell us the early program estimates will be higher than initially projected in 2018. We are much farther along in our planning and designs, but additional items impact the program’s ability provide a full cost estimate at this time.  These include:

• Dramatically changed economic conditions – first major COVID-19 impacts affected the Portsmouth Naval Shipyard (PNSY) Dry Dock 1 (DD1) project.
• Continued infrastructure degradation.
• The extent of facility and shop reconfiguration, which result from completion of the Area Development Plans (ADPs) that are currently underway.
• Fidelity in sequencing and interdependency of investments – as a result of master planning efforts associated with the first ADP at Pearl Harbor Naval Shipyard (PHNS).


Q3:  SIOP is primarily focused on dry dock construction at the public shipyards, and optimization is not being given enough of a priority. What is the program doing to prioritize optimization efforts?

A3:  Dry docks are critical to conducting maintenance availabilities. The Navy is prioritizing those dry dock efforts that are required to execute planned availabilities. Infrastructure and capital equipment efforts will follow, as they remain integral to SIOP’s overall success in developing 21st Century shipyards for the Navy.


Q4:  Is Line of Effort (LOE) 1 prioritized over LOE 2 and 3?

A4:  No. The three LOEs are mutually supporting, not mutually exclusive. While LOE 1 started first, it was because LOE 1 is focused on the construction or modernization of dry docks. These projects had a known requirement early on, while LOE 2 comprises the studies, modeling and simulation at the shipyards; first at the facilities level and then at the equipment level to determine the path toward optimization of the shipyard activities. The planning and project development for many of these projects is currently underway; and over time, we will see the majority of the work shift from LOE 1 to LOEs 2 and 3.

Q5:  What is SIOP doing to de-conflict ongoing and future projects with maintenance availabilities at the shipyards?

A5:  PEO II/PMO 555 SIOP coordinates with Naval Sea Systems Command (NAVSEA) and shipyard leaders on a regular basis to ensure projects are sequenced to de-conflict with maintenance availabilities. The program also supports ongoing NAVSEA transformation efforts such as NSS-SY.  The program also remains closely aligned to the fleet maintenance scheduling process by attending the annual fleet scheduling conference and also has a program office at each shipyard that engages directly with shipyard leadership and production teams to ensure alignment of construction and maintenance schedules.


Q6: Given the magnitude of the SIOP construction projects, how does this impact the shipyard workers (how does this impact NAVSEA’s workload)?

A6:  SIOP works at all echelons to coordinate and integrate the workload of the construction projects with the work taking place within the shipyards to support submarine and aircraft carrier maintenance availabilities.

Q7:  How does SIOP improve resiliency and mitigate environmental risks at the shipyards?

A7:  All SIOP construction projects will be planned, designed, and constructed in accordance with the Administration’s objectives for climate change, sea level rise, seismic vulnerability, and energy efficiency/resiliency. The majority of the Department of the Navy’s (DoN) existing infrastructure at the four naval shipyards was constructed to outdated codes and is, therefore, at a greater risk to climate change than new buildings that have demonstrated much higher survivability. The investment in America’s four public shipyards enhances the sustainability and resiliency of these major infrastructure facilities, mitigating the effect of adverse environmental conditions such as sea level rise, flooding and severe storm, or seismic events. These improvements will address the disproportionately high and adverse human health, environmental, climate-related and other cumulative impacts on disadvantaged communities. SIOP leverages the on-going DoN mission to improve installation resilience in the face of climate change. These facilities will meet the needs of future shipyard maintenance, while also improving the facilities to reduce the Navy’s impact on the environment and the local community.
