Apparatus and method to secure items in or around coastal and shoreline areas including sandbars. In one embodiment an anchor includes a shaft having an outer surface and opposing upper and lower ends and an auger attachable to the shaft for penetrating into material of an earthen medium and driving the shaft lower end into the earthen material. A first wall is connected to the shaft outer surface to create a cavity having an opening into which material may enter the cavity as the auger rotates. When a portion of the anchor is in the earthen material and after at least one of the plurality of concentric cylinders is penetrated into the earthen material, the earthen material is moved into the annular cavity.

The application relates to a floatable offshore wind turbine with at least one floatable foundation. The floatable foundation includes at least one floating body. The floatable offshore wind turbine includes at least one anchoring arrangement configured to fix the offshore wind turbine to an underwater ground while the offshore wind turbine is in its anchoring state. Further, the floatable offshore wind turbine includes at least one height adjustment device configured to change the vertical distance of the floatable foundation to an underwater ground surface of the underwater ground and/or to a water surface during the anchoring state based on at least one specific meteorological environmental parameter of the offshore wind turbine.

Disclosed herein is an overwater photovoltaic panel installation structure having an environment-friendly marine-farm-type mooring anchor module that supports a photovoltaic panel on the water and includes a growth space where aquatic organisms are growable. The environment-friendly marine-farm-type mooring anchor module including a growth space where aquatic organisms are growable, includes an anchor module body defining an external appearance thereof, a frame section disposed inside the anchor module body and made of a more rigid material than the anchor module body, and a connection section exposed through an upper surface of the anchor module body and having both lower ends coupled to the frame section. The anchor module body has a plurality of growth space sections recessed from at least one surface thereof to provide a growth space for aquatic organisms.

A mooring system comprising: a ballast platform; and a chain comprising a plurality of links that are pivotally connected to each other via parallel pivot pins such that the chain is configured to not rotate about a vertical axis that is orthogonal to axes of rotation of the pivot pins, wherein the chain has proximal and distal ends, and wherein the proximal end is attached to a top of the ballast platform and the distal end is configured to be attached to a buoyant object.

The present invention discloses a floatable flow-resisting and sand-resisting multi-functional device. The device includes a hollow floatable body, a flow-resisting and sand-resisting plate, a flow-resisting and sand-resisting net and a mooring system, wherein a plurality of flow-resisting and sand-resisting plates are arranged, each of the flow-resisting and sand-resisting plates is arranged perpendicular to a seabed, a top end of the flow-resisting and sand-resisting plate is fixed to the bottom of the hollow floatable body, the flow-resisting and sand-resisting net down to the seabed is mounted between every two of the flow-resisting and sand-resisting plates, one end of the mooring system is connected to the hollow floatable body, and the other end of the mooring system is fixed to the seabed.

Embodiments of an underwater monitoring system are provided. In one embodiment, the system has an anchor stake connected to a vented pipe. The pipe has an interior and an exterior and is configured to house a sensor in the interior. The vents on the vented pipe are configured to exchange water between the interior and the exterior while protecting any interior sensors.
