Princes Wharf #4
30/06/2021
A busy berthing wharf in Hobart, Princes Wharf #4, was showing its age and needed thorough remediation.
CSIRO engaged VEC Civil Engineering and joint venture partner SAVCOR for repairs and remediation.
Built in 1963, Prince Wharf #4 had experienced concrete corrosion and spalling (breaking) to the main wharf and fender system.
The remediation was done on a working port site, which also houses CSIRO buildings and scientific staff.
The project included:
- Removal of redundant cathodic protection.
- Installation of a hybrid cathodic protection system.
- Galvanic and impressed current cathodic protection.
- Removal of redundant bollards and refurbishment of others.
- Hydro demolition of defective concrete wharf elements.
- Concrete repairs to existing wharf structure.
- Installation of a Trellybord fender system.
- Installation of an RV Investigator shore power system.
Challenges included managing changes to planned work and ensuring minimal disruption to stakeholders including nearby residents and businesses.
The project was finished in time for the wharf to receive Antarctic ship RV Investigator.
