CORROSION-AND-CHAFING-RESISTANT, MOORING SYSTEM AND METHOD

摘要

A mooring system provides an anchor, imbedded in a sea floor from which arises a line to a mid-line float resisting entanglement by operation of a “worm grip” providing a tortuous path without exceeding permissible working loads nor reducing the tension capacity of the line. A slack region accommodates changing tides, before entering into an upright tube weighted at a lower end and flanged at an upper end thereof to secure a buoy in place. The embedded anchor is driven into the sea bed by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface.

主权项

1. A method for anchoring to an underwater substrate, the method comprising:
selecting a substrate forming a floor beneath a water feature; providing a head, having a lead end and trailing end, the head being secured to a source of water pressurized above the pressure of the ambient water feature at the floor; ejecting the pressurized water from the lead end; drilling, by the pressurized water exiting the head, a bore in the substrate for a pre-selected distance; removing the source of pressurized water; and leaving the head in the bore.
