Vessel Impact Protection

Previous Issue: February 27, 2012
The City of Vancouver retained Associated Engineering to evaluate the historic Burrard Bridge and make
recommendations for rehabilitation and safety improvements. As a part of our evaluation, we have
assessed the effectiveness of and the requirements for the protection of piers in the water that are
vulnerable to ship impact.
1 Introduction
The Burrard Bridge is located in False Creek. Shipping in False Creek consists of barges supplying
material to the ready-mix concrete plant on Granville Island; light day-cruiser vessels; as well as
small fishing boats, sailboats, yachts, rowing-boats, kayaks and canoes. The speed limit of 5 knots
(9 km/h) applies to all navigation in False Creek. As ocean-going freighters do not navigate False
Creek we have not considered the possibility of a large ocean going freighter colliding with the s ; s ; s c ; s a ; an s

4 Conclusion
In conclusion, based on the results of our evaluation described above, we confirm that the mainpiers of the Burrard Bridge, P3 and P4, can safely withstand our estimated vessel impact force.
Pier P2, south of the navigation channel, is highly unlikely to be exposed to barge impact; however
based on our analysis, this pier can readily withstand the resulting impact force as well. Therefore,
the piers do not need to be protected from vessel impact by an external fender system.
