A floatable offshore structure, in particular a floatable offshore wind turbine, includes at least one floatable foundation with at least one floating body. The offshore structure further includes at least one anchoring arrangement configured to fix the offshore structure to an underwater ground in an anchoring state of the offshore structure. The anchoring arrangement includes at least one anchor connection between an anchor and the floatable foundation and at least one position stabilization device configured to change the length of the anchor connection between the anchor and the floatable foundation in the anchoring state based on at least one attitude parameter of the offshore structure and at least one attitude set point parameter.

A mooring arrangement for a floating vessel includes a linear anchor winch and an elongate mooring arm. The mooring arm is coupled to a mooring arm bracket via an articulating joint and the arrangement is adapted to receive an anchor chain. The bracket is attached to the vessel at the gunwale of the vessel, so that the bracket at least partially extends above the deck of the vessel. The anchor winch is coupled to or integrated with said bracket.

A dredging system for removing material under a structure may include a barge body including a plurality of barge sections, each barge section of the plurality of barge sections configured to selectively be fully submersed or partially submersed to adjust a height of the barge body. A dredging system for removing material under a structure may include a winch system attached to the barge body and including a cable. A dredging system for removing material under a structure may include a drag beam coupled to the barge body via the cable and configured to vertically move via the winch system between a deployed position and undeployed position.

A flexible lifting tether system for lifting a marine vehicle or object is described which is capable of significantly improving the primary characteristics of an existing cable by enhancing load-carrying capabilities (e.g. in air), modifying the tether to have altered specific gravities in water, and relieving torsional stresses when in operation.
