The Cathodic Protection Repair of Berth 4&5, Port of Brisbane

1999
Godson, I.B.

The Port of Brisbane’s berths 4 and 5 at Fisherman Islands were contracted in 1979-1980, forming 600 metres of container berth supporting several 1000 tonne container cranes. The structure was constructed with cast in situ concrete beams and deck, supported by steel tubular piles. 

Significant concrete deterioration was identified and monitored from 1994. 

The Port’s primary requirement was to address the onset of severe concrete deterioration tot he wharves’ structure, which was confined to the crane support beams, receiving slabs, the abutment wall and fender panels. The main aim was to achieve an extended 40 year life from the structure with minimal on-going maintenance or further rehabilitation. Whichever solution was chosen the structure had to continue to function as a fully operational container wharf, whilst rehabilitation works were being carried out.
