Floating System Case Study

NEW ZEALAND’S BIGGEST GANGWAY - 29 METRES



CLIENT: Total Floating Systems and Auckland Transport
PROJECT: 9m x 2.7m gangway, raised deck and ramp
YEAR: 2015
LOCATION: Auckland, New Zealand

THE CHALLENGE
To design a gangway that would set a new standard in ferry terminal infrastructure.
If you have ever been to Auckland city you will know what traffic is. The city’s transport infrastructure is under increasing pressure as the city expands and it is governing body Auckland Transport’s responsibility to deliver a service that will cope with this growth. One focus for the organisation in 2015 was the upgrade of the tired, outdated wharf that serves the Fuller’s public ferry ser-vice. With increasing numbers choosing to commute by ferry or enjoy day trips on the harbour, Auckland Transport decided to upgrade Pier 4, a ferry berth at the terminal. However, this was not just to be any upgrade, there was a desire to a set a new standard in ferry terminal infrastructure to ensure the new pier could endure the increasing demands of commuter traffic in the City of Sails.



THE SOLUTION
A 29m covered aluminium gangway.
Auckland Transport selected Total Floating Systems and Manson Engineering to design and build the solution. The two have worked together on several successful projects over the years and there was a mutual understanding of the standards and challenges involved. Total Floating Systems were charged with making the concrete pontoons, doing the piling and managing the installation process. The Manson team were responsible for manufacturing the gangway, raised deck and ramp. The brief came with a few hurdles; it had to be built under strict deadlines, safely support the weight of 400 people, affix to a heritage wharf and the install had to impose as little disruption to Auckland’s busy public transport system as possible. Aluminium was selected to build the 29m gangway which connects the heritage wharf to the pontoon. Due to aluminium’s natural anti-corrosive properties it is ideal for the harsh marine environment. Careful thought went into the on-going maintenance of this project and commuters are unlikely to be disrupted with future gangway maintenance as there is no requirement to recoat aluminium. The massive gangway was made off-site in the Manson Engineering workshop and barged to the terminal to minimize disruption to traffic. Installation to the heritage wharf was relatively easy as aluminium is a light¬weight material. Now installed, the smart 29m covered area provides shelter for up to 400 passengers, easing congestion on the main wharf. The project was completed on time and the happy customer (Total Floating Systems) has since commissioned the build of a similar structure at the neighbouring Devonport terminal.
