Automatic detection system of oil spillage into sea waters

An automatic detection system for control of oil spillage into sea waters comprising a plurality of optical fiber cables connected each at the first ending to a control box having an electronic processing and alarm means, and a plurality of light transmitters and light detectors connected to said first endings of said optical fiber cables;

• and the second endings of said fiber cables are connected to a plurality of sensors located remotely in the open sea;
• and each of said sensors is a part of a closed loop of a light signal transmitted by one of said light transmitters through one of said optical fiber cables through said sensor, and received by one of said light detectors provided in said control box;
• and each of said sensors consists of a floating buoy affixed by mechanical means to a permanent location in the open sea, so as to allow said buoy free vertical movement but limit its horizontal movement;
• and said buoy is constructed of a light weight floatable material, and has its center of gravity adjustable and stabilized by a weight, so that when it floats, the central part of said sensor rests at sea level and said buoy is provided with a central bore, into which said second optical fiber cable's ending is positioned;
• and a plurality of concentric channels are provided from all sides of said bore, leading sea water from the outer surface of said buoy inwards;
• and said second optical fiber cable's ending is terminated in said bore and provided with a light indicator;
• so that said light signal, transmitted through said optic fiber cable form said light transmitter, passes through said light indicator and when an oil slick enters said bore, the light parameters' change can be instantaneously detected by said light detector and said electronic processing means of said control box set on said alarm means.
