Abstract
An apparatus for anchoring a structure, such as a drilling platform, to a floor of a body of water has a movable jet nozzle operably disposed in a chamber which is lowered to the floor of a body of water. The jet nozzle is operable to slurry a portion of the floor underlying the chamber, and a pump is provided to evacuate the slurried portion of the floor to provide an excavation into which the apparatus may be lowered. Another pump may depressurize the chamber to provide a pressure differential to hydrostatically urge the apparatus towards the floor of the body of water.
