Methods and apparatus are disclosed for a self-directed (i.e., autonomous), steerable gravity-embedded anchor. This anchor free-falls through the water column, accelerates due to gravity and uses its kinetic energy to embed itself into the seafloor so as to function as an anchor for mooring of both floating vessels and other underwater structures. Unlike existing gravity-embedded plate anchors, this device can steer itself to its intended target location on the seafloor, enhancing placement accuracy and allowing release directly from an installation vessel on the water surface, thereby greatly simplifying installation. |
