Pier D Replacement, Naval Base Kitsap - Bremerton, WA
RFP Engineering for this design/build project was provided by Senior/Key Wood Harbinger engineering staff that developed 40% pier design, 60% upland design, and 90% Substation X design including all mechanical and electrical utility systems.
Wood Harbinger also provided electrical construction period services for the U.S. Navy during the design/build contractor’s design and construction phase.
The project required demolition and replacement of the existing Pier D. A new state-of-the-art 2,000-foot long by 100-foot wide concrete pier, new 60 MVA -115 kV: 11.75 kV double-ended substation, fire-water and domestic water distribution as well as oily water, steam, condensate, compressed air and sanitary main distribution and ship-to-shore hydrants. The power distribution and shorepower mounds on the pier were specifically designed to accommodate both 5 kV and 15 kV CVN loads. This pier is immediately adjacent and can also accommodate our next pier replacement project (Pier B) to also incorporate 34.5 kV infrastructure.
