Naval architecture and design firm Glosten has unwrapped a new tug design – the CT-120, a tug specially built for long-distance and emergency deep-sea towing and moderate-duty anchor handling.
At 120’× 39’× 23’, with over 6,800 horsepower and 95 short tons of bollard pull, the tug is suited for heavy ocean tows, including large deck cargo barges approaching 20,000 deadweight tons.
“Unique from conventional line-haul tug designs of similar size, it can accommodate a variety of powerful medium-speed engines and modern exhaust gas treatment equipment, including both large SCR units and diesel particulate filters (where required) made possible by its expansive engine room and large stack casings adjoining the deckhouse,” said Seattle-headquartered Glosten.
The design “is optimized for constructability and low operational costs and can be outfitted with either ASD or conventional twin-screw propulsion.”
The CT-120 “also offers substantial tank capacity for unsupported long-range towing operations and its largest tanks, positioned fore and aft, can be fitted with cofferdams to support conversion to methanol, if desired,” the company said.
“This sub-200 GRT design is optimized for constructability and low operational costs, and is adaptable for either ASD or conventional twin-screw propulsion, and optional tunnel thrusters in the bow and skeg afford dynamic positioning capability,” the company said.
Pairing these features with either a single or double-drum tow winch and modest anchor handing capability “make CT-120 a very practical option for supporting a range of offshore installation projects.”
