ABSTRACT:
A method and system for dispersing oil in the event of an oil leak into a body of water from an oil tanker or an oil drilling platform. There is provided structure for detecting the existence of a leak from a container of oil generally surrounded by a body of water into which the oil is leaking; structure for storing an oil dispersant at the site of the leak; and structure responsive to the occurrence of the leak, for automatically causing the dispersant to be released from the containment structure into the leaking oil. In an oil tanker, the system and method may be implemented by providing structure for detecting a leak in the oil tank wall, suspending a container of dispersant inside the oil tank, and providing structure for rupturing the dispersant container in response to the detection of a leak so that dispersant is caused to mix with the oil in the tank before the oil leaks therefrom. In the case of an offshore oil drilling platform, the system and method may be implemented by leak detection devices mounted to the drill casings or on buoys in the water body, one or more dispersant containers with release chutes directed toward the water body mounted to the side of the platform, and structure responsive to the detection devices for opening the dispersant containers in response to the detection of an oil leak.
