Abstract: A self-deploying stabilizer for marine anchors is disclosed wherein the silizers fold into a collapsed, compact configuration for easy stowage and automatically self-extend to a working position after anchor deployment for stable anchoring performance. The stabilizers have hinged movable arms which include angled reaction force plates which operate against drag forces created on the plates as an anchor moves through various materials in a marine environment to force the stabilizer arms to move to a fully open position. Springs may be used for assisting or restricting deployment of the movable arms, and lock bolts or break-away shear pins may be provided to retain the movable arms in a desired position.

Abstract: A ground anchor is provided comprising a first part engageable within an anchoring medium such as, for example, the ground, along an insertion axis; a second part to which loads are, in use, attached; and linking means interconnecting the first and second parts yet permitting displacement of the second part with respect to the insertion axis; so that when load is applied to the second part after the first part has been inserted within the anchoring medium the second part can alter position without moving the first part and thus reduce the effective loading on the first part. The second part preferably includes supplementary anchoring which penetrates the surface of the anchoring medium upon application of load to the anchor.

Abstract: An improved, slow burning jet embedded anchor assembly for use in sedimentary strata and similarly nonconsolidated or rocky ocean bottom surfaces is shown. The anchor comprises an inertially loaded reaction member above a substantially elongated anchor shaft, coaxially positioned around an elongated drive tube assembly. The anchor shaft has a number of open cross-section triangular sheet metal anchoring fins, providing substantially low resistance to penetration within the strata, but providing substantially high resistance to sideways displacement forces, as would be imposed through a standard anchor rod. The anchor is positioned by lowering the inertial reaction unit and embedded by the weight of the inertial reaction unit a distance into the surface layer of the subocean strata. An internal detonator control assures vertical embedment unless the anchor is vertically positioned. The anchor is remotely fired after initial embedment.

Abstract: A quick deployment vehicle (QDV) for implanting a transponder or beacon on he ocean bottom in an upright position exposed for receiving or transmitting acoustic signals. The vehicle includes a ballistic body of separable fore and aft sections. The fore section includes a core mass for penetrating the ocean sediment, and the aft section includes a beacon for signal transmission. A predetermined interval after impact, as determined by a programmed deceleration profile stored in memory, the sections will separate. The sensed deceleration of the vehicle is compared at predetermined intervals to the stored profile, and when the sensed level is less than the stored level, a squib is fired to separate the two sections. The aft section penetrates and remains exposed above the sediment, while the fore section further penetrates into the ocean bottom.

Abstract: An anchor includes an approximately frustoconical main body having a small height, and a chain attaching shank is located at the center of the main body and is rotatable about a substantially vertical axis.

Abstract: An underwater pile driver assembly that includes a vertically disposed tubular housing that may slidably engage the upper end portion of a pile, with the housing having an upper open end, and the housing supporting an anvil that may be placed in abutting contact with the pile. An impact imparting ram is slidably and sealingly mounted in the housing, and may be successively raised to a first position therein. Pump means are provided to successively evacuate water from the interior of the housing between the ram and anvil. After each evacuation the ram is released to be forced downwardly by the hydrostatic head imposed on the upper surface thereof to impact the anvil, with the force imparted to the anvil being transverse to the pile to drive the latter downwardly. The greater the distance of the upper end of the housing from the surface of the water, the greater will be the magnitude of the downward force exerted on the pile each time the ram impacts the anvil.

Abstract: A deepwater propellant embedded anchor system having emergency release menism for separating an anchor fluke assembly from the gun assembly. In an emergency, a sear pin is rotated by a lever and release line to disengage the fluke assembly, thus allowing the fluke assembly and explosive cartridge to drop away and allow water to flood the gun barrel and soak the primer for disarming the anchor system.

Abstract: A permanent mooring for use with boats and the like is provided with folding flukes on a tubular body. The flukes are formed as portions of a cylinder and in their folded position completely envelope the mooring with a smooth cylindrical surface which decreases unwanted drag during installation. A connection is provided for attaching a high-pressure water pipe and the forward end of the mooring anchor is tapered so as to form a water jet nozzle. The mooring is directed to the bottom of the water and, upon pumping the water through the pipe and out of the nozzle, the mooring anchor is forced downwardly into the sand or mud by the washing action of the water, the weight of the mooring itself, as well as additional downward pressure on the water supply pipe by the installation personnel.

Abstract: An anchoring system comprising a pointed anchor body having either a wire apped therearound in one embodiment thereof or a coiled wire disposed within a hollow portion of the anchor body in a second embodiment thereof. One end of the wire is fixed to the pointed end of the anchor body and the other end projects through a pusher plate at the other end of the anchor body, behind which is an explosive or propellant charge for actuating the anchor. When the charge is ignited the anchor body is driven out of the charge housing, which is configured to retain the pusher plate, causing the wire to unwind as the anchor body embeds itself.

Abstract: A system for placing piles into the seafloor by using pressure differential as the driving force. The pressure differential is created by a pump unit located either within or external to the pile. Operation of the pump unit which displaces both water and soil across a bulkhead section, enables the pile to be driven into and under the seafloor. A section of piling with a pump unit can operate as an uplift anchor, and multiple pumps on a large diameter piling can be embedded into the seafloor as a large foundation.

Abstract: Method of generating rotary or turbine power within a deepsea environment, for drilling a hole in the seabed and dropping of a mooring pile in the hole so drilled. Rotary turbine power is developed by admitting water through a submerged turbine and into an evacuated sphere. The turbine drives an auger which engages and drills a hole in the seabed. An inorganic polymer may be supported in the evacuated sphere, so as to be reactant with admitted seawater for bleeding off of pure water and hydrogen gas at a surface location.
