ABSTRACT:
A system for releasing an anchor moored to the bottom of the sea, based on a mechanical device being inserted between the lower end of the anchor suspension chain or cable and the upper part of the arm of the anchor. The mechanical device basically comprises two in-between articulated parts, which, in their normal position, are blocked in order to form a single body for attaching the above-mentioned lower end of the anchor suspension cable to the upper end of the anchor arm. Through the use of an additional and independent accessory or piece which is made to slide along the very anchor suspension cable, both parts of the device are unblocked, by tractioning said additional and independent piece. The unblocking implies that one the parts of the device will be only attached to the lower end of the suspension cable, while the other part will be attached to the upper end of the anchor arm, all that so that the tractioning force for raising the anchor will be exerted from the lower part thereof, i.e., in a sense practically opposite to the axle of the plane formed by the claws or bills of the anchor. The way of tractioning the anchor is achieved by virtue of the fact that between the lower base of the anchor and the part being attached when unblocking to the lower end of the suspension cable, a small chain is fixed.
