New in the Delaware lightering fleet: OSG Horizon ATB

摘要

The second of three large articulated tug-barges (ATBs) built for Overseas Shipholding Group (OSG) America went to work on the Delaware River this past spring, with a third identical combination expected to join its predecessors next spring. New on the Delaware as of April is OSG Horizon, another in a class of vessel that is said to be the largest ATB operating in North America. The tug itself is a 12,100-hp heavy-fuel-burning powerhouse with 77 feet height of eye at its massive wheelhouse. Horizon is matched to a 655-foot barge with capacity of 342,000 barrels of oil. The two are linked together with a coupler system using 64-inch pins provided by Intercontinental Engineering. It is described as the largest coupler system produced by that company.
