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.

A kayak anchor support system includes a first support arm having a first end opposite a second end, wherein the first support arm is removably securable to a kayak via at least one mounting bracket. A proximal end of a second support arm is affixed to the first support arm adjacent to the first end. The second support arm extends orthogonally from the first support arm such that a distal end of the second support arm is maintained in an elevated position above the kayak. A pulley is affixed to the distal end of the second support arm. An anchor cable is engaged with each of the pulley and a reel, wherein the reel is disposed opposite the pulley. An anchor is affixed to a terminal end of the anchor cable, whereupon actuation of the reel, the anchor is selectively movable between a raised position and a lowered positioned.

A resident remotely operated vehicle may be deployed subsea by deploying a remotely operated vehicle (ROV) (200) configured to be disposed and remain resident subsea for an extended time where the ROV comprises an ROV electrical power connector port (202) to be operatively connected to an electrical power supply (700) dedicated to the ROV. An RTMS configured to be disposed subsea for an extended time is also deployed subsea (210), typically proximate the ROV. A subsea docking hub subsea is also deployed subsea proximate the RTMS and operatively connected to the ROV and the RTMS. In addition, an umbilical is connected from the subsea docking hub to a subsea structure and a signal supplied from the subsea structure to the ROV.

Described and disclosed is a foundation structure of an offshore structure, in particular of a wind turbine, with a floating foundation, including at least one floating body for floating on the surface of the sea, at least one anchor for anchoring the at least one floating body the seafloor and at least one holding element for holding the at least one floating body to the at least one anchor. At least one transmission cable extends from the at least one anchor along the at least one holding element to the at least one floating body and/or back. To enable a reliable monitoring of the anchoring of the offshore structure, provision is made for the transmission cable to be guided in sections through at least one protection element provided between the holding element and the at least one anchor and/or the at least one floating body.

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.

A variable weight boat anchor having an added weight storage capacity for submerged unloading of added weight is presented. Remote signal from a boat triggers the release of added matter in the anchor for a lighter pulling.

A tillable anchor has a number of planar sides, typically four, attached to a base and to one another, forming an enclosed structure with a cavity therein. Attachment points for a deployment line and for mooring lines are provided. After the empty anchor is deployed to the seafloor or other water bottom, an inlet and an outlet permit placement of a flowable weight material into the cavity. The anchor may have an extended skirt around the base to enhance holding capability.

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.
