Embodiments, including apparatuses, systems and methods, for attaching autonomous seismic nodes to a deployment cable. In an embodiment, an apparatus includes a seismic node having a direct attachment mechanism configured to directly attach the seismic node to a deployment line, the direct attachment mechanism being configurable between an open and/or unlocked position and a closed and/or locked position to release and retain the deployment line.

A cleat for a boat includes a cam mounted to the boat, where the cam has a rotatable toothed surface for pressing against a line. The cleat also includes a guide mounted to the boat adjacent the cam, where the guide has a surface for directing the line above a top of the cam. In addition, the cleat has a slot formed in the surface of the guide, which permits the line to be moved into opposition with the rotatable toothed surface of the cam.

Embodiments, including apparatuses, systems, and methods, for attaching autonomous seismic nodes directly to a deployment cable. The nodes may be attached to the deployment cable by a removable fastener or insert. The fastener may be a staple that surrounds the cable and rigidly couples to the node to securely fasten the cable to the node. The fastener may be secured into the node itself, a housing or enclosure surrounding the node, or into a receiver or mechanism attached to the node. Other fasteners besides a staple may include bands, wires, pins, straps, ties, clamps, and other similar devices that may be inserted around a portion of the deployment line and be removably coupled to the node. After retrieval of the node, the fastener may be removed and discarded.

An offshore floating structure such as a wind turbine includes a number of improvements. The floating structure can include a chain engaging system configured to prevent any lengthwise movement of a mooring chain. The floating structure can also include a mooring fixture pivotally coupled to the hull to prevent shock loads from being transmitted directly from the mooring line to the hull. The floating structure can also include installation aid structures that provide additional water plane area and/or buoyancy to the structure. The floating structure can also have a hull that is optimized for use as an offshore wind turbine.

The present invention relates to a system and method for mooring of and supply electrical power to a vessel, the system comprising a mooring buoy, a mooring connection being a combined mooring and electrical connection by comprising a mooring line and an electric conductive cable for supply of said electrical power and a retractable vessel connector provided at an end of the mooring connection, wherein the vessel connector is a combined mooring connector and electrical connector. The system further comprising or involves a gripping device arranged on a vessel wherein the gripping device is configured to grip and lock said vessel connector to moor said vessel to said mooring buoy.

A method and a spinnaker launching and/or recovering system releasably attachable to the deck or integrated on the deck or into the hull of the sailboat for launching and/or recovering a spinnaker. The spinnaker setting and/or recovering system has a first spinnaker guide member, which is attachable, e.g., to the bow, a bowsprit or is built into the deck near the bow with an opening through which the tack line and/or a retrieval line attached to the clew corner or to the lower luff of an asymmetric spinnaker or retrieval lines attached to the tack corner and the clew corner or to the lower luff of a symmetric spinnaker. Running with the asymmetric spinnaker, tack corner may be taken forward by a second tack line operated from the cockpit. The first and second spinnaker guide members may be connected by a sleeve, e.g., made of textile, or a solid material.

The present invention relates to systems for securing connectors of risers in petroleum production units. In this scenario, the present invention provides an autonomous system for securing a riser support, said system comprising (i) a riser support (32) connected at its bottom end to a submerged riser (34) and at its upper end to a tensioning element (30), (ii) a supporting ledge (20) comprising a through-hole (22) through which the tensioning element (30) and at least part of the riser support (32) pass, (iii) a securing device (40) located on the supporting ledge (20), said securing device (40) sliding relative to the supporting ledge (20) and driven by an actuator (48), wherein the securing device (40) slides between an unlocked position and a locked position on the through-hole (22), wherein, in the locked position, the securing device (40) can engage with locking in a connector (38) of the riser support (32) after the connector (38) has passed through the through-hole (22) of the supporting ledge (20). The present invention further provides an autonomous method for securing a riser support associated with the system described above.

A mooring device for mooring a water craft to a mooring berth. The mooring device includes an engaging element borne by the water craft or the mooring berth, and a lock borne by the mooring berth or the water craft, respectively. The lock includes two catch bars spaced out and extending vertically, at least a part of the engaging element being adapted to engaging between the two bars so as to be held by the lock and enabling the mooring of the water craft to the mooring berth. The catch bars are mobile relative to each other between a locking position in which the catch bars are brought closer to each other and maintain the engaging element and an unlocking position in which the catch bars are moved apart to enable the removal or insertion of the engaging element.
