HIGH-LEVEL simulations are being undertaken by TasPorts to determine whether TT Line’s existing ropax terminal at east Devonport can be modified and safely used for the new, larger Spirit of Tasmania ferries.

The continued use of No. 1 berth has been proposed as a temporary alternative, given contractual problems mean the new terminal at No. 3 will not be completed before early 2026. The first of the new vessels, Spirit of Tasmania IV, was handed over on 12 September but remains at the Finnish builders’ yard amidst speculation it and its sistership will be ‘parked’ until suitable infrastructure is available.

TasPorts has been tasked with modifying No.1 to physically accommodate the larger ships on a temporary basis, at a reported likely cost of more than $50 million. However, safety concerns have been expressed by, amongst others, master mariners, and the operator of the adjacent Berth No. 2, Searoad Shipping.

CEO Anthony Donald told Tasmanian media simulation testing, being conducted at both Smartship in Queensland and at the AMC in Launceston, would inform the safest and most efficient option.

“The testing looks at the design from a risk, safety, regulatory, compliance and operational efficiency perspective, which will help to inform decision making,” Mr Donald said.

“The simulation exercise uses cutting edge technologies, including a computer simulation of the vessel model, which accurately mirrors vessel performance, and integrates this with a detailed model of the river.

“The vessel is tested in a range of varying wind, depths and tidal current flows to identify the limits of safety.

“The simulations are undertaken with skilled masters who have a detailed understanding of the vessels and port and river environment, and with oversight from TasPorts’ Harbour Master.”

Mr Donald said the simulation testing, assessment and reporting process was expected to be finalised by mid-October and the results will be handed to the Tasmanian Government. In turn the government has undertaken to brief stakeholders on 1 December.

Meanwhile, further hearings of the Tasmanian Parliament’s Public Accounts Committee in Hobart today heard evidence from former TT Line chairman Michael Grainger, who was effectively forced out by the government in mid-August.
