| Abstract: | The safety limitation of large new-built seagoing vessel design and operation is investigated to ensure safety of the new vessels towed through bridge area. We analyze the maneuverability characteristics of a towing fleet, and develop a mathematical drift model of ship motion for the fleet. Based on this drift model and the hydro-meteorological conditions in bridge area, we propose a method to systematically ascertain the safety limitations of water stages, current, wind, speed and visibility. This method is conducive to the safety of both navigation and bridges when large towing fleets transit through bridges. |
