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.
