(WASHINGTON) — On April 1, 2013, the 473-foot tanker Harbour Feature struck the Sarah Mildred Long Bridge in Portsmouth, N.H., after the ship broke free from its moorings at the New Hampshire State Port Authority's Marine Terminal Wharf. The bridge sustained $2.5 million in damage; the Harbour Feature sustained $1 million in damage.
The National Transportation Safety Board (NTSB) has determined that the probable cause of the breakaway of Harbour Feature and the subsequent allision with the bridge was the inadequate mooring arrangement made by the master and the pilot for the vessel’s location and the prevailing tidal conditions.
