The invention is comprised of a Quick Anchoring Equipment system () which permits underwater connection and disconnection of anchoring lines () to anchoring devices that are already fixedly attached to the bottom of the sea. The Quick Anchoring Equipment () consists of chain cable, cables, hooks and buoys specifically organized and configured, which, are attached at the submerged end of the anchoring line (), which makes it possible with a single support boat (), together with a remote operated vehicle (), to carry out this whole anchoring lines () operation fundamental to floating platforms (). The invention also includes the method to install and uninstall the Quick Anchoring Equipment ().

Apparatus and method of operation for quick anchoring equipment

A pile for anchoring a floating structure in deep water includes an elongated body provided with a tapered pointed tip at the lower end thereof and a closure disc at the upper end thereof. A plurality of radially and axially extending fins are secured to the pile adjacent the upper end thereof. The elongated body of the pile is filled with material having a high specific gravity distributed in such a manner that the center of gravity of the pile is located well below its center of buoyancy. The process for installing the pile uses the potential energy generated by the free fall of the pile from a vessel in order to ensure that the pile penetrates the ocean floor.
