Sydney's wharf upgrade program: are lessons being learnt?

The upgrade of Sydney's ferry terminal infrastructure started with Milsons Point Wharf in December 2010.  It came as a surprise to many that, just over six years later, Milsons Point is again being upgraded (or "expanded") by the addition of another berth face. This will allow two ferries to berth at the same time, eliminating one of the systemic causes of ferry delays - berthing conflicts between inbound and outbound vessels. 

One of the mysteries surrounding Roads and Maritime Services' (RMS) upgrade program is why this was not done as part of the first upgrade. The closure of the wharf for a further six months and, presumably, duplication of costs are unfortunate. Berthing conflicts between inbound and outbound ferries at Milsons Point, plus access by non regulated ferries and charter boats were significant issues long before 2010. Increasing the frequency of Darling Harbour services in the AM and PM peaks from October 2017 will add to the urgency of this work, but the need was always there.

On the positive side, the design of the new terminal provides a glimpse of what Sydney's wharf infrastructure ought to look like! It will have two separate landing platforms, both with outside berth faces only.

All other dual berthing intermediate stop wharves designed to date by RMS have been single pontoons with capacity for vessels to berth on either side. McMahons Point and Balmain East are examples of this. But these double sided landings have a significant disadvantage, which RMS notes in its Review of Environmental Factors for the Expansion of Milsons Point Wharf: (a double sided landing) "would require ferries to reverse out of the inside face berth." 

An urban transit ferry line with multiple intermediate stops must ensure maximum efficiency in the line of approach of vessels to a wharf.  Reversing should be avoided wherever possible as it adds unnecessary time into the run cycle and slows the journey for passengers. 

This was figured out a long time ago in the Brisbane Ferries network, where none of the dual berthing wharves have double sided landings. They are either long single pontoons with sufficient room for two outside berth faces or they use two pontoons, similar to Milsons Point (except the landings at Milsons Point are actually hydraulic platforms, not floating pontoons).

A further disadvantage of the double sided pontoon is they are prone to crowding problems. The pontoon may need to accommodate two groups of passengers waiting to embark and enable disembarking passengers from two vessels to exit quickly at the same time. Not an easy task with one small pontoon.

Curiously, RMS has persisted with the concept of a single double pontoon for the soon to be upgraded Cockatoo Island Wharf, despite acknowledging its deficiencies in relation to Milsons Point. The plan for Cockatoo Island is shown below.

And it must be said that the expanded Milsons Point wharf is not without flaws, either. It may give a glimpse of what a dual berthing wharf should look like, but the two landing platforms are unfortunately far too small for a high demand stop. I can't imagine there is enough room for the stern and midships gangways on First Fleet or Heritage Class ferries to be used, which is really necessary to manage large crowds.

There is no question that the RMS wharf upgrade program is making improvements to the operation of the Sydney Ferries network. We have yet to see in Sydney, however, the level of thoughtfulness of design which is evident in the Brisbane Ferries system. This comes at a cost to taxpayers and means the network is less useful to passengers.
