These 25-ft tugs feature twin John Deere model diesel engines with a combined rating of 600 hp and conventional shaft drives with reversing gears.
“The Lady Shayne and Lady Dashelle 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,” said Ron Mason, Marine Operations Manager and New Construction Projects Manager for Smithbridge.
The Shayne and Dashelle will handle a160-ft by 80-ft piling barge as it goes through the piling process for the terminal.
With these tugs, Smithbridge can adapt various kinds of utility equipment to the front of the vessel for different project requirements –“thanks to the excellent job St. Johns did in developing our hydraulic anchor handling frame for the front,” said Mr. Mason.
