Two big ASD tugs custom-designed for moving LNG tankers

摘要

The four azimuthing stern drive (ASD) tugs at the Moran Towing of Lake Charles dock, located off a lonely stretch of Gulf Coast highway near Cameron, La., have a combined horsepower of 25,800. Two of the tugs, Hercules, built for Suderman & Young Towing (SYT), and Tristan K, built for Bay-Houston Towing (BHT), are 6,300-hp, 7500 class Z-Tech units. Delivered in 2011, they joined Catherine C. Moran and Loretta B. Moran, both 6,600-hp z-drive tugs. Moran, in a joint venture with SYT and BHT, is providing escort and assist services to LNG ships berthing at the newly-built Cameron LNG facility near Lake Charles, La. The Cameron LNG receipt terminal is owned by Sempra LNG, a subsidiary of Sempra Energy.
