ABSTRACT:
An automatic detection system for control of oil spillage into sea waters comprising a plurality of optical fiber cables connected each to a control box and to a plurality of sensors located remotedly in the open sea, and each of the sensors is a part of a closed loop of a light signal, transmitted from the control box and received back by it. Each of the sensors consists of a floating buoy affixed to a permanent location in the open sea, having its center of gravity adjustable and stabilized, so that when it floats, the central part of the sensor rests at sea level. The buoy is provided with a central bore, into which the optical fiber cable's ending is positioned; and a plurality of concentric channels are provided from all sides of the bore, leading sea water from the outer surface of the buoy inwards. The optical fiber cable's ending is provided with a light indicator; so that when an oil slick enters the bore, the light parameters' change can be instantaneously detected by the light indicator and the control box set on the alarm.
