Deep water high capacity anchoring system and method of operation thereof

Deep water high capacity anchoring system, which includes a metal anchoring structure (100) in a preponderant conical form, provided with a cable (120), cast on the ocean floor (S) from a handling ship (F), provided with a pumping system (300) that supplies one of the extremities of anchoring structure's (100), with a flow of liquid, through a hose (302), and additionally characterized by the anchoring structure (100) presenting four basic and fundamental functions:

• 1—directs the upward-moving of an eroded substrate under said anchoring structure,
• 2—offers little resistance to fixing the anchor,
• 3—at the same time offering high breakaway resistance,
• 4—propitiating its own descending vertical displacement using its own weight and the external shape tending to be conical;
• by virtue of these functions, the layout of the anchoring structure complies with a certain minimum parameters, such as present a conical circular form, or pyramidal form with no fewer than three faces;
• the angle (φ) of placement of the external surfaces (101) of the anchor structure (100) with the horizontal should be within the range of 30° to 60°;
• said anchor structure (100) be provided with a central body (103) preferably made up by a segment of metal tubing that extends vertically from the apex (104) of said anchor structure (100) up to a height corresponding to its inverted base;
• in the central body (103), coincident with the apex (104), the tip is attached to the anchoring structure (100), which is provided with a jetting device (200);
• the other extremity (103b) of said central body (103) is provided with an anchor ring (105) and a mean for coupling a hose (302);
• an anchor ring (105) will be fixed to a cable (120);
• a fluid is injected into the extremity (103b) of the anchor structure (100), through a hose (302), crossing the inside of the main tubular body (103) and is expelled, in the form of a continuous and directed jet, through the other extremity of the anchor structure (100), and through the jetting device (200);
• said jetting device (200) consists of a directional conical tip (201), which is metallic and massive that connects to the lower extremity (103a) of the central body (103), sealing it;
• the directional tip (201) is provided with a series of openings or nozzles (202) placed perpendicular to the main axis of the central body (103), along the entire perimeter of the jetting device (200);
• simultaneously, a second series of openings or nozzles (203) placed along the entire perimeter of the second jetting device (200), which have their outlets turned towards the apex, so as to release the fluid in an ascending direction parallel to the lower external surface of the anchor structure (100);
• the pumping system consists of pumps (301) and a hose (302);
• the pumps (301) may be located in the handling ship itself (F), or submerged;
• the liquid pumped by the pump (301) may have a density that is greater than, equal to, or less than that of the sea water.
