New tug combines handling capabilities of tractor and azimuthing stern drive tugs
Suderman & Young Towing is modernising its fleet with a new Z-Tech tugboat. It has taken delivery of Ted C Litton from Gulf Island Shipyards to boost its Texas-based tug fleet.
This 29.8-m tug is one of five tugs the shipyard is building for Suderman & Young to a Robert Allan design to assist large container ships and car carriers berthing at ports on the Texas Gulf Coast.
Ted C Litton was built to a Z-Tech 30-80 design, which incorporates the best handling and operational characteristics of both Z-drive tractor tugs, azimuthing stern drive tugs and the RAstar series hullform.
Robert Allan said this “emphasises the safe and capable operation of ship-handling operations with large ships, particularly those with extreme flares.”
Z-Tech 30-80 can operate in push or pull mode under the flared ends of large container ships and car carriers because these tugs have a relatively low forward sheer, and a wide, heavily fendered bow.
Ted C Litton’s main propulsion includes a pair of Caterpillar 3516E diesel engines certified to comply with the US Environmental Protection Agency’s Tier 4 emission requirements. These drive Schottel SRP 510FP Z-drive units.
