Abstract
A method of controlling the position of an on-water water curtain device for building a water curtain on the water in order to stop or disperse dangerous gas leaking from a ship or to block flame and radiant heat due to the leaking gas. The method comprises the steps of detecting positions of the ship and the water curtain device, detecting wind direction and tidal current, and adjusting the position of the water curtain device to an optimal position in accordance with detected values so as to maintain the diaster prevention water curtain substantially perpendicular to the leaking gas.
