In 2014-15 we invested over $27 million delivering 177 projects.
In 2014-15 we invested over $27 million delivering 177 projects around the state. This was our largest workload for remediating and renewing our commercial port infrastructure, marine fleet and community assets.
In 2015-16 we’re continuing to roll out major projects in Tasmania.
The largest maintenance dredging project in 10 years
The dredging project was essential to restore and maintain safe navigational access for port customers including TT Line (Spirit of Tasmania), Searoad and Cement Australia.
Dredging within the Port has been necessary for over 100 years. The dredging is required to remove the material infilling the channel, swing basin and berths from naturally occurring river run off (the Mersey River) and coastal processes (including winter storms).
Dredging commenced on 21 May 2015 and was completed at the end of July 2015. 380,000m3 of material was removed from the Port comprising of sand and cobble from the inner and outer entrance channel and silt and clay from the swing basin and berths.
A key part of the project was the implementation of the Adaptive Dredge Management Plan (ADMP) which reflects Tasports’ commitment to managing environmental risks associated with the disposal of dredged spoil.
The monitoring program (which included specialist scientific equipment on the seabed) was maintained throughout the project with real time data provided on a number of parameters including turbidity, salinity, water temperature, oxygen levels, tide and current, wind speed and the movement of silt in the water column.
“The ADMP includes methods to monitor environmental risk and scalable dredging mitigation measures that can be used if required. The expertise and methodology demonstrated in this Plan are some of the key reasons why the Federal Department of the Environment provided Tasports with a permit to undertake the sea disposal activities related to the dredging.
The monitoring results recorded throughout the project correlated closely with the forecast modelling which predicted extremely low volumes of turbidity and dredged material movement at the disposal site.
Tasports utilised the services of worldwide marine dredging contractor, Rhode Neilson, to undertake the dredging work. The chosen vessel, the Brage R recently completed similar dredging projects in the ports of Dampier and Newcastle.
As anticipated the vessel’s size and maneuverability proved advantageous in dredging the port’s tighter berth pockets, particularly on Devonport West. The vessels pump configuration and pipe thickness was also successful in minimising noise emission, a key benefit for the surrounding community.
The project reached the ports targeted design depth which is expected to keep the port clear for navigation for many years to come.
Tasports invested $6.7 million in this project to ensure the safe access for over 800 ship calls per annum by Tasports’ key Devonport customers who contribute over $150 million per annum to Tasmania’s Gross State Product.
Logistics optimisation within the port zone.
The Burnie Optimisation Project is a tri-partite agreement between the Tasmanian Ports Corporation Pty Ltd (Tasports), Tasmanian Railway Pty Ltd (Tasrail) and Toll Transport Pty Ltd (Toll).
The joint project is the first agreement of its kind between the three key stakeholders and is a positive step for Tasmania in relation to state wide collaboration and integration of freight transport systems.
The project will improve the capacity and efficiency of container handling through the port by enhancing the existing rail intermodal terminal and its links with the Toll terminal.
For Tasports the benefits include a strategic upgrade of port container capability as well as improved port security and traffic management measures.
Both TasRail and Toll will benefit from improved state wide freight capacity due to the delivery of a rail head in northern Tasmania to complement the container handling capability of the Brighton intermodal facility in the south.
In addition, the improvements will have a positive impact on the community due to the expansion of the existing rail yard. Importantly for the community this means that trains will no longer need to be shunted along the main waterfront, providing safer access to the beach and improving the overall aesthetic of the area.
Expanded maintenance and renewal of high-use assets
In 2013-2014 Tasports initiated an expanded maintenance and renewal program to focus on a priority list of high use community-based assets. The community asset sites are Sullivan’s Cove, Strahan, Stanley and Inspection Head on the Tamar River. Tasports wants to ensure that these areas, which are continuing to grow, are able to be enjoyed well into the future and that the number of community events and tourism operators that utilise these assets continue to do so, and are not adversely affected by any change of access or load restrictions which may occur if maintenance is not able to be undertaken. For the past two years now Tasports has been continuing to undertake asset remediation across Sullivan’s Cove. In 2015 we are turning our focus to the much needed Franklin Wharf remediation.
Tasports is continuing the remediation of waterfront assets in Sullivan's Cove. We are cognisant of the community and tourism value of Sullivan's Cove and are working hard to ensure the much loved waterfront can continue to be used well into the future. In 2016 we will be implementing the first stage of the replacement of Franklin Wharf, the existing wharf was constructed in stages from 1932 and since this time has been heavily utilised.
Starting 3 March 2016, the first area to be replaced is from the corner of Brooke Street Pier through to Elizabeth Street Pier. Independent engineering advice has concluded that traditional remediation to this wharf structure would not be a suitable solution; therefore the existing deck and beams will be demolished, with new deck and beam elements constructed atop the original concrete piles.
Over 2016 Tasports contractors, will first saw cut and remove sections of the deck. The removal of the deck slabs requires the presence of a crane on site. To ensure the safety of vehicles and pedestrians in the area this activity will be supported by significant traffic management activities. The ticket office which houses Hobart Historic Cruises will need to be removed in order to allow replacement of the wharf structure underneath. Subsequent to the deck removal, wire cutting and removal of the beams will occur, which will enable remediation work to be done on the existing piles. Once this is completed Tasports will once again utilise a crane to place the new prefabricated pile heads, beams and wharf planks. The new concrete wharf deck will then be poured in situ to complete the new surface.
The new wharf deck aims to sustain the ongoing community use of the area for the next 25 years. This project is essential to ensure that Sullivan's Cove continues to be a vibrant and busy place. We appreciate the patience of the local community and visitors to the area while this project is underway.
