Extra heavy duty hydrostatic anchor together with its extra heavy duty tether cable

摘要

A permanent anchor embedded and encapsulated at unusual depth in the sea floor can become effected by ejecting an automatically fired chain tethered projectile into the sea floor and then covering it with a large mass of tremie concrete followed sequentially by the seizure to chains attached to the anchor flukes of the projectile by extra heavy duty tether cables only after the completion of the placement effort and making the tether cables vertically taut by means of a plurality of buoyant octahedrons.
