The NTSB record keeps in mind that, in 2015, a Coast Guard Towing Safety Advisory Committee (TSAC) assembled a job pressure to offer suggestions to recognize services for protecting against allisions in between hauling vessels as well as tows with frameworks (such as bridges) freight barges. In the TSAC’s last record on air draft, dated May 10, 2016, the board suggested that all hauling security administration systems:
“clearly state that it is the towing vessel master’s responsibility to review properly published information on overhead clearance, and, based on this information determine and verify all overhead clearance issues along the intended route as part of Voyage Planning / Navigational Watch Assessment. The Master must be allowed to rely on the published height of any overhead clearances and has no duty to independently verify this information.”
The TSAC additionally suggested that when a third-party vessel (barge, crane, and so on) is being hauled, the third-party proprietor ought to be accountable for supplying precise air draft details to the driver relocating that tow.
