Marine payload handling craft and system

A marine handling craft and system is intended for use in deploying, inspecting and receiving vessels and payloads to and from locations on, under, over or near water and wet soils in potentially turbulent aquatic or atmospheric conditions. The marine handling craft may operate as a robot, or deployed from a crane or boom on a mother ship or other platform or helicopter so that it can transport and mate and dock at various locations, such as supply ships or autonomous marine vessels, at a stand off distance to limit potential harm to valuable assets. A sliding fastener and track are included on the marine handling craft so that it can be tethered and lifted by a single line or cable, and so can be manipulated by a single crane or helicopter. The utility of the handling craft is not limited to the transport of payloads and it may function as a stand-alone vessel for various remote sensing purposes. Smart communication between the marine handling craft and other vessels or other nodes in a distributed computer network facilitates simultaneous, hierarchical and multi-tasking control of the craft and permits verification and inspection of payloads, which might otherwise cause damage when proximate to more valuable assets.

Launch and recovery system

The launch and recovery system provides a dive wing and drogue assembly that is towed behind a ship by cables. The dive wing imparts a downward thrust to the drogue, so that the drogue is towed underwater, placing tension on the cables. The cables become stiff due to the speed of the ship and the weight and depth of the dive wing and drogue assembly, so that the cables take on the character of rails. The boat or watercraft to be launched is placed on a sling carriage that is slidably mounted on the cables, so that the sling slides down the cables, launching the watercraft in the stable wake of the ship. The watercraft is recovered by tying a winch cable or line to the watercraft, winching the watercraft back onto the sling, and winching the sling back onto the fantail of the ship.

Hydraulic lift for small watercraft mounted to a boat transom

A transom bracket enclosing a hydraulic power cylinder is mounted to the transom of a watercraft. An actuation rod of the power cylinder moves multiple lift arms connected to a platform bracket supporting a platform for supporting a small auxiliary watercraft. Electrical or manual operation of the power cylinder causes the platform bracket to move in a vertical direction either upwards out of the water or downwards into the water. A lock mechanism operated by a lock cylinder locks the lift apparatus in place when not in operation. Grooves on sides of the transom bracket and transversely extended pins connecting the linkage arms provide a downward stop to movement of the lift apparatus.

Launch and recovery system for unmanned undersea vehicles

A system operable by a single workman safely launches and recovers an unmanned undersea vehicle (UUV) using a motor-driven carriage to transport the UUV to the water. The UUV is fitted to a reconfigurable sabot. An elevating ramp on the carriage supports the sabot and UUV on an elongate conveyer assembly having inclined rollers aligned with motor-driven belts to selectively outwardly and inwardly displace the UUV between the carriage and the water. Hinge members are used to rotatably connect the elevating ramp to the carriage, and a lifting mechanism connected to the carriage and ramp rotatably displaces the ramp about the hinge members. The rollers and belts displace the UUV on the conveyer assembly. A winch on the elevating ramp has a line connected to the UUV to lower and raise the UUV during launch and recovery operations.

Method of installation of a tension leg platform

A method and system for attaching a TLP to its tendons using pull-down lines to rapidly submerge the hull to installation draft while compensating for inherent hull instability during submergence and to provide motion arrest and aid in station keeping. The system includes tensioning devices mounted on the TLP, usually one for each tendon. Each tensioning device is equipped with a pull-down line which is connected to the corresponding tendon. The TLP hull is submerged to lock-off draft by applying tensions to the pull-down lines connected to the top of the tensions, or by a combination of applying tensions to the pull-down lines and ballasting the hull. As the tensioners take in pull-down line, the hull submerges, i.e. the draft increases. After lock-off, high levels of tension in the pull-down lines can be rapidly transferred to the connection sleeves by slacking the pull-down lines, thus allowing the TLP to be made storm-safe much faster than by prior art methods which require de-ballasting to tension the tendons. In concert with TLP installation, the method may be used attach the mooring tendons to the seabed by suspending and lowering the tendons into their foundation receptacle in the seabed.

Method for measuring continuously-variable load precision of large-scale floating dock in floating state

The invention relates to the technical field of engineering ships, in particular to a method for measuring continuously-variable load precision of a large-scale floating dock in a floating state. The deck plane of the floating dock and the deck plane of a ship body are measured respectively by two electronic total stations (total stations for short), deformation data generated by the two electronic total stations in the ship body dragging process are fed back to a central control room at the same time based on a uniform reference, and the central control room is guided to perform water compressing adjustment or water discharging adjustment on the ballast tank of the floating dock. The method has the advantages that: the dynamic deformation of the floating dock and the ship body in the ship dragging process are instantly and statically fed back, and the instant deformation states of the floating dock and the ship are effectively measured, so that the central control room of the floating dock is guided to adjust the water compression in each ballast tank, the deformation precision and the launching safety of the ship body in the dragging process are ensured, a great number of working hours are saved, and the launching dragging efficiency is improved.
