US-based shipbuilder St. Johns Ship Building has delivered two custom built twin screw push tugs, the Lady Shayne and the Lady Dashelle, to Smithbridge of Brisbane, Australia.
Equipped with a pair of John Deere 6081 diesel engines, the two 25ft tugs have a combined rating of 600hp and conventional shaft drives with reversing gears.
Smithbridge marine operations manager and new construction projects manager Ron Mason said the tugs will be assigned to a very high profile marine construction site in Botany Bay in Sydney, Australia where a new bulk liquid terminal is being built to accommodate tankers.
According to Smithbridge, with the two tugs it can adapt various kinds of utility equipment to the front of the vessel for different project requirements.
Both the vessels will have a length of 25ft, beam of 13ft and draft of 3ft, and will handle the 160ft by 80ft piling barge as it goes through the piling process for the terminal.
The US shipbuilder will also start work on a second pair of identical tugs, as well as a pair of 39ft truckable tugs, for the Australian firm.
Smithbridge specializes in civil and marine design and construction and operates in Australia, New Zealand, Guam and New Caledonia.
St. Johns Ship Building features over 900ft of bulkhead waterfront including a 400ft launch basin, a 1,200 tonne dry dock, a 425ft by 75ft fabrication shop as well as complete carpentry, electrical and machine shops.
