All of Crowley's Articulated-Tug Barges (ATBs) are built under the ABS SafeHull program for environmental protection. This dynamic-based ship design evaluation system founded on engineering principles puts the vessel design through an exhaustive review to identify structural loads and strengthen the vessel structure. This finite analysis assists in ensuring the vessel structure can withstand extreme circumstances while at sea.
