International Dredging Review

International Dredging Review

The Port of Brisbane (Australia) Corporation took delivery of the new $40 million hopper dredge Brisbane on November 3 2000.

Leaving the NQEA shipyard in Cairns on October 24 the new dredge sailed down the Queensland coast calling at Townsville and Gladstone en route.

The Port of Brisbane will use the dredge to maintain its shipping channels in Queensland ports replacing the dredge Sir Thomas Hiley which was retired after 27 years of service.

The Brisbane incorporates state-of-the-art technology and environmental design including a fluidized discharge system which reduces turbidity by pumping the water from the dredging operation into the ocean from beneath the dredge.

A 13-person crew will operate the new dredge on a 24-hour basis.

The Sir Thomas Hiley’s last project was a beach renourishment job at Woorim Beach on Bribie Island.

In eight days the Hiley pumped 60000 cubic meters of clean sand close to the low water mark. This placement of the sand at the surf line will allow the natural wave action to push it onto the beach increasing the sand on the beach while protecting the existing beach from further erosion.

Port of Brisbane Corporation CEO Graham Mulligan said the Corporation was pleased to cooperate with the Environmental Protection Agency and Caboolture Shire Council by providing the Hiley and the dredging expertise to undertake this important community project.
