Working in partnership with Hong Kong-based architectural consultants Au Posford, Royal HaskoningDHV reviewed the design requirements and prepared a performance specification for the walkways before selecting a specialist contractor via tender procedures.
The five purpose-built passenger walkways provide a weatherproof connection for all passengers and crew members between the moored cruise liners and the new terminal building. They are fully automated, with each walkway traversing the length of the concourse alongside the berths on rails. The walkways are lifted and lowered using electro-mechanical devices.
A number of elements needed to be incorporated into the performance specification for the walkways. Their design and structure needed to accommodate movement of the vessel caused by tidal and environmental changes, both when traversing the quayside and while carrying passengers. The width of the walkway design needed to be limited to ensure the store access doors on the sides of the vessel remain accessible. A tie-down facility was also incorporated into the design for occasions when typhoon warnings are issued, and each walkway is connected to a backup generator in case of mains power failure from the terminal building.
