Described herein are mooring systems for floating structures and methods for manufacturing and installing such mooring systems. The mooring system may comprise a line having a first end operatively connected to the floating structure and a second end operatively connected to an anchor underwater or to a seabed, wherein the line comprises at least two substantially rigid links joined together; and a watertight sheath surrounding the line and extending at least along a length of the line from a position below the waterline to a position above the waterline.

A mooring apparatus (50) comprising a guide portion (55) for guiding a portion of a first mooring line (60), an arrangement (65) for connecting or coupling the apparatus (50) to a second mooring line (70), and a lock (75) or lock means. The guide portion (55) is moveably connected to the arrangement, and the lock is connected to, attached to or provided on the arrangement. A system (250) for tensioning a mooring line, the system comprising the mooring apparatus (50) and the first mooring line (60) and/or the second mooring line (70). A method of tensioning a mooring line, wherein the method comprises providing the system for tensioning a mooring line, and the method further comprises applying a pulling force to a first portion of a first mooring line (60) in a direction away from the apparatus (50).

A boat hook assembly includes a clamping assembly, which is attachable to a pole. The clamping assembly includes a mechanical clamp in one embodiment and a magnetic clamp in another embodiment adapted to temporarily secure a boat hook which is configured to connect to a receiving member on a boat dock. The boat hook is configured to receive a boat line extending from the boat. The temporary securement of the boat hook by the clamping assembly is overcome by an operator moving the pole in a manner to release the clamping assembly from the boat hook, wherein the boat remains connected to the dock by the boat hook and the extended boat line. The boat hook assembly includes structural element and arrangements to prevent unintentional release of the clamping assembly from the boat hook.

A release mechanism for separating sections of mooring lines has a main body with two separable first and second halves or sections. A hydraulic assembly within the main body is controlled by an acoustic system, and moves a rod and button so as to move locking shoes within the main body. The locking shoes hold the first and second sections locked together, or alternatively release them to disconnect the mooring line. In addition to the acoustically controlled hydraulic assembly, the release mechanism has a mechanical disconnect, which is operated by pulling the release mechanism into a chain fairlead or the like, or by pulling an encircling member such as a trigger sleeve into the release mechanism. The release mechanism may include instrumentation to transmit various operating conditions of the release mechanism when in use.

A system (100) for attaching devices of subsea equipment to a line (10) comprising a line holding mechanism (11,110) and a line holding unit (404). The line holding unit (404) comprises a 5 longitudinal slit (403) for receiving the line (10), multiple gripping elements (13,130,230), and at least one resilient element (12,120,220), related to one subsea device. The resilient element(s) is/are configured to force the multiple gripping elements (13; 130,230) in a direction towards the line (10), whereby the line holding unit (404) is locked to the line (10) in a locking position. By the invention an improved latching device and an accompanying system for attaching and 10 detaching subsea equipment to and from a line is obtained.

An adjustable tensioner particularly suited for use in applying tension to a halyard line circuit on an outrigger is disclosed and features a length of hollow braided rope having a proximate end serving as a first anchor point for attachment to a boat gunwale; a distal end; a loop section positioned intermediate the proximate end and the distal end, and a braid-in-braid section positioned intermediate the loop section and the proximate end; the loop section serving as a second anchor point for attachment to the halyard line circuit; wherein the effective distance between the first and second anchor points is adjusted by reducing or enlarging the size of the loop section; and wherein when tension is applied to the first and second anchor points, the braid-in-braid section provides a self-induced friction amplification effect to prevent an increase in the distance between the first and second anchor points.

A pulley stopper including: a clamp portion that includes a bar-shaped upper clamp and a bar-shaped lower clamp; and a pair of fasteners that are disposed at opposite ends of the clamp portion to couple the upper clamp and the lower clamp. The pair of fasteners and the clamp portion are coupled such that the upper clamp and the lower clamp are fixed side by side through the coupling of the fastener and the movement of a belt disposed between the upper clamp and the lower clamp is stopped.

A fluid actuator arrangement comprises a first cylinder housing including a first head member and a second head member; a first piston body is slidable arranged in said first cylinder housing; the first piston body divides the first cylinder housing interior into a first cylinder chamber and a second cylinder chamber, at least the first cylinder chamber is coupled to a fluid supply. The first piston body exhibits a first through-bore and a second through-bore that extend through the first piston body in an axial direction; a first piston rod is arranged slidable in the first through-bore and a second piston rod is arranged slidable in the second through-bore; and the first through-bore comprises a first engagement and disengagement device and the second through-bore comprises a second engagement and disengagement device, which are arranged for providing individual engagement or disengagement to or from the respective first and second piston rod.
