New Z-drive tug for Suderman & Young

NOVEMBER 11, 2015—The 5,150 hp Triton, the first in a series of four Z-Tech 2400 class escort tugs for Suderman & Young, was recently launched at the Nelson Street facility of the Eastern Shipbuilding Group, Panama City, FL.

Those tugs are all operate by G&H Towing. The Triton is expected to be delivered before the end of 2015.flag

The Triton has two Schottel SRP 1215 fixed pitch Z-drives for propulsion, with an expected bollard pull of 66 tonnes.
