The MULTIBODY AIRCRANE performs relative positioning, predictive control, and ballast control to achieve very heavy-lifting tasks on land or sea. Such tasks allow station keeping and precise transfer of very heavy payloads between ships underway. This scalable multibody system features three subcomponents: AIRSHIP, SKYCRANE and LOADFRAME. This semi-autonomous system combines aerodynamic (kinetic) and aerostatic (buoyancy force) lift with efficient power and propulsion. During low-speed flight, the Airship and Skycrane are decoupled but linked via a reelable Tether Control Line. Beneath the Skycrane, centered on its hull, a patented NIST (National Institute of Standards and Technology) RoboCrane (featuring a computer controlled six degrees of freedom (DoF) cabling system,) is attached, to precisely suspend and control a Loadframe, with or without payload. During subsonic forward flight, these Airship and Skycrane are coupled as a single airframe (fuselage and delta wing.)

A system and process for improving container flow within a port facility, including improved equipment and software for controlling operation and flow of the equipment in the part facility. The system may include a port facility geographically arranged to separate land operations and water operations. Land operations such as over-the-road missions and rail missions may use landside access areas positioned at one end of a yard including rows of container stacks. Water missions such as loading / discharging a vessel may use waterside access areas positioned at the opposite end of the yard. Automated cranes linked with a terminal operating system may pick / drop / shuffle containers and / or refrigerated containers (“reefers”) within the container stacks. Shuttle trucks may be used to pick / drop containers at quayside access points and the waterside access areas. The shuttle trucks may utilize shared wheelpaths. Software systems may be used to implement various principles of the invention.

The present invention represents a procedure for compensating the heave movement of offshore cranes. The dynamic model of the compensation actuator (hydraulically operated winch) and the load hanging on a rope are derived. Based on this model, a path-tracking control unit is developed. To compensate the movement of the ship / watercraft caused by waves, the heave movement is defined as a time-varying disturbance and is analyzed with respect to uncoupling conditions. With a model expansion, these conditions are satisfied, and an inversion-based uncoupling control law is formulated. To stabilize the system, an observer is used for reconstructing the unknown state by means of a force measurement. Furthermore, the compensation efficiency can be improved by predicting the heave movement. There is proposed a prediction method in which no ship / watercraft models or properties are required. The simulation and measurement results validate the heave compensation method.

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.

A container security scanning system may be provided on the second platform for scanning the containers while on the second platform to determine whether one or more preselected chemical, biological, explosive or nuclear materials are present in the containers.

A method and system for transporting an offshore structure such as a wind turbine generator includes a supporting frame in which the offshore structure is assembled on land in an upright configuration. The frame is used for lifting the structure onto a transport vessel, on which it is retained in the upright configuration. At its location of use, the offshore structure is transferred to a pre-prepared foundation. The foundation is provided with a frame which cooperates with the supporting frame. The supporting frame includes a plurality of legs having hydraulically controlled feet. The frame of the foundation includes an equal number of supporting formations on which the feet ultimately rest. The feet are moveable in response to the hydraulic control along a nominally vertical line of action and provide a damping arrangement for the mounting of the offshore structure.

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.

The AUVs are configured to acoustically communicate with the underwater vehicle or a second surface vessel for deployment and retrieval operations. The underwater vehicle and / or second surface vessel is configured to instruct the AUVs to leave the subsea station or underwater vehicle and to travel to their intended seabed destination. The underwater vehicle and / or second surface vessel is also configured to selectively instruct the AUVs to leave the seabed and return to a seabed location and / or a subsea station for retrieval.

This invention provides a means of loading, processing and conditioning raw production gas, production of CGL, storage, transport, and delivery of pipeline quality natural gas or fractionated products to market. The CGL transport vessel utilizes a pipe based containment system to hold more densely packed constituents of natural gas held within a light hydrocarbon solvent than it is possible to attain for natural gas alone under such conditions. The containment system is supported by process systems for loading and transporting the natural gas as a liquid and unloading the CGL from the containment system and then offloading it in the gaseous state. The system can also be utilized for the selective storage and transport of NGLs to provide a total service package for the movement of natural gas and associated gas production. The mode of storage is suited for both marine and land transportation and configured in modular form to suit a particular application and / or scale of operation.
