Abstract
A submarine cable laying system having an underwater cable laying device towed by a cable laying ship along the sea bottom is disclosed. The underwater cable laying device comprises a cable depressing wheel, a mechanism for elevating and lowering the cable depressing wheel, means detecting passage of repeaters and the like under said cable depressing wheel, and means for detecting the length of a part of the cable having been laid by the cable laying device. The output signals of the two detecting means are sent to a controlling device provided on said cable laying ship, and are so processed that the output signal from the controlling device can control the elevation or lowering of the cable depressing wheel automatically each time the repeaters or the like pass through the cable depressing wheel.
