U.S. Navy, Puget Sound Naval Shipyard
Coastal Engineering and Dredge Project Support
The U.S. Navy’s four public shipyards, Norfolk Naval Shipyard (NNSY), Portsmouth Naval Shipyard (PNSY), Puget Sound Naval Shipyard (PSNS), and Pearl Harbor Naval Shipyard (PHNSY), perform a vital role in national defense by executing maintenance on surface vessels and submarines for combat readiness. PSNS, located in Bremerton, Washington is the largest of the nation’s four public shipyards and is the only location on the West Coast that can make significant repairs to the U.S. Navy aircraft carriers (CVNs).
With focus on operations paramount, the Navy’s aging shipyards also need to adequately sustain and optimize their facilities and infrastructure. Serving as Coastal Engineer Lead for a large A/E consultancy, Lally performed site physical processes analyses, wind hindcasting and wave modeling for 100-year recurrence interval storms, detailed vessel wake and propeller wash modeling for a range of design vessels, and applied these results to engineer improvements to the PSNS shoreline armoring system under a Remedial Action Contract (RAC).
Lally was also requested under the RAC contract to share dredging and dredged material disposal knowledge gained formerly as a dredging contractor in support of the Navy’s navigation deepening and contaminated sediment removal project at PSNS.
