A subsea line clamp assembly (1) has a body (10) having an axis and a clamp member (50), assembled in segments around a subsea line (3), and tethered to a subsea anchor (5). The clamp member (50) is movably located within the body (10). The inner surface of the body (10) and the outer surface of the clamp member (50) have respective tapered portions as part of teeth (32, 72) arranged to inter-engage. Adjacent teeth (32, 72) may be separated by axis-parallel portions. The clamping force on the subsea line (30) can be maintained at a consistent clamping force throughout the service life of the subsea line (3), despite the actions of creep and compression acting to reduce the outer diameter of the line (3).

Watercraft docking apparatus including a spreadable clamp attachable to a watercraft to be docked, an elongated pole attached at one end to the spreadable clamp, and structure attaching mechanism attached to an opposite end of the elongated pole. The spreadable clamp and the structure attaching mechanism are both designed to prevent lateral horizontal movement of the elongated pole.

An improved button shackle (2) and method of making the same. The button shackle (2) generally comprises a single length of braided rope (3) noosed at one end by looping one end of the rope and running it back through itself, such that the end passes through the braids, to form a noose. The two ends of the rope are then woven together to form an eye, and a novel two-piece button (4) is inserted onto the eye. The two-piece button includes an inner disk (12) formed with opposing yokes (22, 24) for receiving the rope (3), and an outer collar (14) for holding the rope (3) captive once inserted into the yokes (22, 24).

A watercraft securement device including a boat attachment line configured for connection to a watercraft and a dock attachment line configured for connection to an anchoring structure. A tensioning apparatus is connected to the boat attachment line and the dock attachment line. The tensioning apparatus is configured to adjust the length of one of the boat attachment line or the dock attachment line. The tensioning apparatus further includes a pulley for engaging the adjustable length and a ratcheting mechanism. The ratcheting mechanism operates to permit rotation of the pulley in only one direction when engaged, and to permit free rotation of the pulley when released. The ratcheting mechanism maintains tension as the adjustable length is pulled through the pulley.

Some embodiments provide ocean rig releases apparatus, systems and methods. In some implementations, a rig release apparatus comprises: a body having a first and second mating sections each being connected to one of two separate tethers; at least one locking shoe movably secured with the first mating section and movable between a first position configured to secure the first mating section and the second mating section together and a second position configured to allow the first mating section and the second mating section to separate; and a locking system configured to releasably lock the first and second mating sections and prevent hydrostatic pressure created by ocean depths from inadvertently unlocking, wherein the locking system comprises: a restraint system that inhibits the movement of the at least one locking shoe, and comprises a stop element that when released physically retracts to unlock the locking system allowing.

A fender hook is disclosed that is formed by a base material carrying a gripping material disposed between sections of hook and loop material. By wrapping the base material over upon itself, the gripping material is brought into frictional engagement with a mounting substrate such as a nautical railing and is held in place by the hook and loop material.

A boat strap is described herein, as well as a system and method of attaching two boats with the boat strap. The boat strap is made up of a main strap, a free cam, a lower cam strap, and a lower cam. The free cam is mechanically connected to the main strap, where the main strap loops through a free cam strap connector. Additional stitching connects the main strap to itself forming a free cam loop to connect the free cam to the main strap. The lower cam is mechanically connected to the lower cam strap. The lower cam strap loops through a lower cam strap connector, and a primary stitching connects the lower cam strap to itself forming a lower cam loop to connect the lower cam to the lower cam strap, wherein the primary stitching further connects the lower cam strap to the main strap. The main strap loops through a connector on one boat and runs through the lower cam to attach the boat strap to the rail. The main strap then is run through the cam on a second boat strap on the other boat, attaching the boats.
