Bell Street Pier Marina, Cruise Ship Dock and Passenger Boarding System
This project was a comprehensive redevelopment of Seattle's downtown waterfront covering Piers 64, 65, and 66 and the
uplands across Alaskan Way to the Highway Viaduct. Features of the new facility included hotels, condominiums, retail
shops, a convention center, maritime museum, restaurant, cruise ship terminal, marina, and fish-processing facilities. Marine project elements included a full-service marina for transient moorage, a 900-foot-long fixed breakwater, and a passenger boarding system.
The Bell Street Pier Passenger Boarding System provides barrier-free access to passengers for all except the most extreme tides, which is fairly unique because the Northwest is known for its extreme tidal fluctuations.
The gangway is mobile (self-powered), allowing setup in several locations on the dock and stowage when the
pier is occupied by other vessel types.
Smith Cove Passenger Boarding System (Terminal 91)
The new passenger boarding gangway system is a mobile system with the ability to access five designated terminal building gate locations while serving vessel doors anywhere along a 270-foot connection zone near the bullrail. The system maintains a 25-foot-wide by 15-foot-clear-height access corridor along a building by bridging over a drive lane on the terminal pier; this corridor includes a bullrail for dock operations, with the exception of a width less than 10 feet where the vessel walkway bridges over this corridor. The new system’s mechanically controlled gangways and ramps allow fast and trouble-free deployment to the terminal building and vessel.
The Smith Cove gangway system, once deployed to the vessel, follows vessel movement with minimal user input for adjustment with the changing tide levels. Tide range is approximately 12 feet. The entire system features fully ADA-compliant ramps and gangways throughout the entire operational range of the system.
