A disconnectable mooring system for offshore semi-submersible floating structures. A disconnectable buoy has a number of mooring lines which include a buoy chain between the mooring chain and the buoy. The mooring chain and the buoy chain are connected via a three way mooring connector, with the third connection configured to pull the mooring connector to a mooring point on the structure. In a first configuration the buoy is disconnected and supports the mooring chains for recovery at shallow depths to be pulled in. In a second configuration, the mooring lines are pulled in via the mooring connectors thereby providing a spread mooring to the structure with the buoy chain left as a catenary between the buoy and mooring point.

A watercraft mooring system comprising a plurality of interchangeable mooring members for the temporary mooring of one watercraft to another watercraft or one watercraft to a stationary object such as a dock. The interchangeable mooring members comprising connecting rod member embodiments with adjustable lengths and connecting rod members without adjustable lengths, vacuum-handle member embodiments that provide an initial vacuum and a continuous vacuum to one or more vacuum cup assemblies, and a cleat connector member embodiment that is interchangeable with a vacuum-handle member. Embodiments of vacuum-handle member providing up to three points of omni-directional pivot functionality between the present invention and a temporarily moored watercraft.

Connectors assemblies. The connector assembly can include a stinger and a sleeve assembly that includes a latching mechanism. An outer surface of the stinger can define first and second grooves located toward first and second ends, respectively, thereof. An inner surface of the sleeve assembly can define first and second shoulders located toward first and second ends, respectively, thereof. The latching mechanism can be in an unlocked position or a locked position. When the latching mechanism is unlocked the stinger can be inserted into or removed from the sleeve assembly. When the stinger is within the sleeve assembly and the latching mechanism is locked, the latching mechanism can maintain a first split ring partially within the first groove and partially on the first shoulder and a second split ring partially within the second groove and partially on the second shoulder to secure the stinger within the sleeve assembly.

A release system for a tether line includes a housing having a side that is at least partially open. A tether lead within the housing is adjacent to the side of the housing. A release mechanism in the housing includes a shackle having a closed end and an open end. The shackle is disposed in the housing at a portion therein that is lower than that of the tether lead. The release mechanism also includes a hinge for mounting the shackle within the housing. In a tether-retention mode, the open end of the shackle faces the top of the housing and the shackle is prevented from rotation about the hinge. In a tether-release mode, the shackle is free to rotate about the hinge under gravity wherein the open end of the shackle rotates to face the side of the housing.

Disclosed is a mooring system (1) for mooring a floating vessel. The mooring system includes a connector structure (10) for attachment to a mooring line and an anchor structure (20) to be anchored to a sea bed. The connector structure comprises an engagement portion (14) and an attachment portion (12). The anchor structure comprises an open guide channel (22) extending from an entrance region (24) to a terminal region (26); and sized to accommodate at least the engagement portion of the connector structure. A longitudinal opening to the guide channel provides access for a mooring line connected to the attachment portion, while the connector and anchor structures are connected and disconnected. Connection and disconnection can be controlled from the water surface.

Yoke mooring systems and processes for using same. The system can include a turntable connected to and rotatable with respect to a base. A yoke can be connected to the turntable such that the yoke can at least partially rotate about a longitudinal axis of the yoke and at least partially rotate about a second axis that can be orthogonal to the longitudinal axis. A first and second link arm can be connected to the yoke and to a first component of a first and a second releasable connector, respectively. A first and second lifting line can be connected to the second end of the first and second link arms, respectively. A first and second lifting device can be disposed on a vessel and configured to be connected to a second end of the first and second lifting lines, respectively, to lift and lower the link arms and the yoke.

A mooring latch includes a passive foundation portion and a latching portion. The latching portion includes a mechanism, a conical surface shaped to mate with a conical surface of the passive portion, a connector for connection to a mooring structure and permitting rotation about a horizontal axis. The mechanism has a latched configuration that mates the conical surfaces and permits rotations about a shared vertical axis of the conical surfaces. A mooring line threaded through the passive and latching portions and equipped with one or more stops may be used to guide the latching portion to or from the passive portion and to actuate latching or unlatching or the mooring latch.

Mooring support structures, systems for mooring vessels, and processes for using same. In some embodiments, a system for mooring a vessel can include a mooring support structure than can include a post connected at a first end to a turntable disposed on a base structure. The post can extend out from the turntable and a yoke head connector can be connected to a second end of the post. A distal end of the yoke head connector can provide a disconnection location such that when a yoke head is disconnected from the yoke head connector, the yoke head can fall by gravity from the yoke head connector without contacting the mooring support structure.

A mooring ball system comprising: a mooring ball; a collar attached to the top of the mooring ball; an extendible, retractable, and lockable mast attached to the collar, and extending from the top of the mooring ball; a hook attached near or at the top of the mast; a chain attached to the mooring ball; a mooring line attached to the chain; a loop located at one end of the mooring line; and where the loop is configured to removeably attach to the hook, and where the loop is further configured to be removed from the hook and attached to a watercraft. A mooring apparatus comprising: a collar configured to attach to the top of a mooring ball; an extendible, retractable, and lockable mast configured to attach to the collar, and configured to extend from the top of the mooring ball; and a hook attached near or at the top of the mast.

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.
