Four dry docks the Navy uses to overhaul nuclear submarines in Washington are temporarily closed after the service found they are at risk for earthquake damage, service officials told USNI News on Thursday.
The dry docks, three at Puget Sound Naval Shipyard & Intermediate Maintenance Facility in Bremerton, Wash., and the delta pier at the Trident Refit Facility in Bangor, Wash., are still certified to overhaul nuclear submarines, but the Navy has decided to keep the dry docks empty pending further investigation.
“The seismic assessment and expert validation enhances the Navy’s knowledge of the potential issues associated with a large earthquake occurring during a submarine maintenance availability,” reads a statement from the service.
