Seismic upgrades to Dry Dock No. 4 at Puget Sound Naval Shipyard & Intermediate Maintenance Facility in Bremerton, Ore., have been completed. USS Pennsylvania (SSBN 735) was docked for its extended refit period on May 11 after a testing and recertification of the dry dock. Seismic mitigation work continues at PSNS & IMF’s Dry Dock 5 and at the Trident Refit Facility Delta Pier in Bangor, Ore.
“This seismic mitigation project is a huge undertaking with a lot of moving parts,” said Capt. Jip Mosman, commander, PSNS & IMF. “The Navy is working as quickly and safely as possible to return our dry docks to full functionality, and I extend my sincere gratitude to everyone who has been involved thus far.” The facilities were temporarily closed by the Navy in January following a seismic assessment. A joint venture of Kiewit-Alberici SIOP MACC was awarded the $75.35-million contract for the repairs of Dry Docks No. 4 and No. 5 in February.
