Suderman & Young Christens Z-Tech Tug
Suderman and Young Towing Company, L.P. (S&Y) completed sea trials for its newest tug Thor, which features the ZTech drive, the first of its kind in the western hemisphere, with only four other ZTech vessels operating in the world. The Z-Tech design incorporates design features from standard tug Azimuth Stern Drive (ASD) and Z-drive configurations. With its 360 degree turning wheel the design improves maneuverability while the Thor Z-Tech's much larger skeg boosts towing capability and directional stability. This new operational design is aimed to enable the tug to handle larger container vessels more efficiently. "Because of the deepening, from 40 to 45 ft., and widening, from 400 to 530 ft., of the Houston Ship Channel, bigger ships will call into the Port of Houston's Bayport Facility," said Lamar Doyle, President. Designed to increase power, while providing more maneuverability, the Thor Z-Tech will be able to "move more water, more quickly," according to Doyle. The Z-Tech design was developed by naval architect Robert Allan of Vancouver. Based in the Texas Gulf Coast since the late 1800s, S&Y began as a stevedoring operation in Galveston. Sponsor Gay N. Greer christened Tug Thor Saturday, July 14, 2007 at the Port of Houston's Barbour's Cut Container Terminal.
