| HOME | Homeport Breakwater Pier - Ph 1 USN Homeport Carrier Complex - Everett, Washington |
The Breakwater Pier at the U.S. Navy Homeport Complex is a 90’ wide x 1500’ long structure with a dual function. It is a berthing facility for Navy ships, and it also serves as a breakwater for the adjacent Carrier Pier.
The pier structure is supported by 24" hollow octagonal prestressed piles and decked with precast prestressed panels. The piles are unspliced and over 180 feet long.
The breakwater wall runs along both sides of the pier and the individual breakwater panels span vertically from the pier deck to embedment in the soil at the harbor bottom. The panels are spaced apart horizontally to allow water circulation and free movement of marine life.
