Seismic Mitigation Work on Two Pacific Northwest Dry Docks Begins

15 February 2023

From the Navy Office of Information

This updates a story previously released Jan. 27, 2023. That story, Navy to Temporarily Suspend Some Dry Dock Operations in the Pacific Northwest, is beneath this one.

The mitigation efforts are designed to ensure the safety of the shipyard workforce, Sailors, the local public, the environment, and the submarines.

“Our way ahead is enabled by some excellent engineering work from a diverse team of NAVSEA, NAVFAC and industry experts executed on a very tight timeline,” said Rear Adm. Dean VanderLey, commander, Naval Facilities Engineering Systems Command. “As we proceed with the construction efforts, our engineering team will continue to conduct more detailed analysis to inform both immediate and long term efforts.”

Navy to Temporarily Suspend Some Dry Dock Operations in the Pacific Northwest

Navy Office of Information, Jan. 27, 2023

WASHINGTON -- The Navy will temporarily suspend submarine docking in Dry Docks 4, 5, and 6 at Puget Sound Naval Shipyard & Intermediate Maintenance Facility (PSNS & IMF) and the dry dock at delta pier located at Trident Refit Facility (TRF) Bangor following a planned seismic study and expert analysis.

The recently conducted seismic assessment, executed as part of the Navy’s long-range Shipyard Infrastructure Optimization Program (SIOP), identified potential issues associated with the remote possibility of a large-scale earthquake occurring simultaneously with a submarine maintenance availability. With this new information, the Navy is taking additional measures to further ensure the safety of the shipyard workforce, Sailors, the local public, the environment, and the submarines.

This action does not affect the nation’s strategic deterrent capability or the ability of the fleet to continue its overall mission.

“Our public shipyards are essential to our national defense,” said Vice Adm. Bill Galinis, commander, Naval Sea Systems Command. “We will begin implementing these mitigations immediately and safely return our dry docks to full capacity as soon as possible.”

The Navy is working to minimize delays to ship schedules and fleet impacts. The work packages for each affected availability are being evaluated and structured to continue work pier side when possible. Aircraft carrier maintenance is not impacted by this decision.

A Naval Sea Systems Command led team is working now to safely and efficiently return the docks to service with the additional upgrades in place.
