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.

A rotating fairlead device is provided, comprising a base frame having a bearing support member, a slew bearing mounted to the bearing support member; and an exit sheave assembly mounted to the slew bearing, combined to form a single head fairlead. The single head fairlead may further include a plurality of guide rollers mounted to the base frame adjacent to the slew bearing. A dual head fairlead is also provided, wherein both entry and exit sheave assemblies are mounted on their respective slew bearings on opposite sides of the base frame. Optionally, a load sending device is disposed within the base frame between the opposing slew bearings to detect the load on a cable residing within the dual head fairlead.

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 fairlead includes a chain guide support structure and a clump weight engagement member. A clump weight assembly includes a clump weight body, a clump weight coupled to the clump weight body, and a spring housing. The spring housing includes an upper housing wall and at least one spring operatively coupled between the upper housing wall and the clump weight. The clump weight body may be selectively engageable and disengageable with the fairlead to form a fairlead and clump weight assembly. A method of installing and using the clump weight includes engaging the spring housing with the clump weight engagement member, and latching the clump weight body to the clump weight engagement member.

The present invention provides a mooring apparatus for an offshore construction that makes it easy to install a mooring chain and can moor an offshore construction stably against external force such as waves and wind. The mooring apparatus for an offshore construction includes; a floating member generating buoyancy; and fixing frames coupled to a side of the floating member and combined with a plurality of fixing arms radially extending and being stretchable and retractable, in which mooring chains which are connected to the bottom of the sea are fixed to free ends of the fixing arms respectively, so that as the fixing arms stretches/retracts on the fixing frame, the positions of the mooring chains change.
