Abstract: A multi-use fully restrained platform system for offshore marine applications includes a monopile foundation, an interface piece mounted atop the monopile, and a deck structure coupled to the interface piece. The interface piece provides a standardized connection mechanism that enables various payload configurations to be mounted on the same foundational infrastructure, including wind turbines, oil and gas extraction equipment, hydrogen production facilities, offshore charging stations, electrical substations, offshore datacenters, and marine infrastructure such as bridges. The interface piece includes multiple receptacles configured to receive mounting columns from the deck structure, with the receptacles arranged to accommodate different deck geometries and payload requirements.

Abstract: Techniques are disclosed herein for minimizing movement of a fixed marine structure. Using the technologies described, a wind turbine may be mounted on a fixed marine platform (e.g., a fully restrained platform (FRP)) that is secured by mooring lines that may be maintained at a tension to restrain movement of the platform due to environmental loads (e.g., wind, waves, etc.). The mooring lines may be attached to the platform with assemblies that include a stopper attached to the mooring line and engaged with a mooring porch. The stopper may be positioned and/or repositioned to adjust the tension on the connected mooring line and secured in the adjusted position using the various systems and techniques described herein.

Abstract: The present invention discloses methods and apparatus for converting water wave energy into electricity on a utility scale. The device comprises: (1) an oscillating body that effectively responds to waves in all six degrees of freedom: surge, sway, heave, roll, pitch, and yaw, (2) a restraining system to prevent the oscillating body from being displaced by steady environmental loads, and (3) a power takeoff system comprising linear generators which are directly driven by the oscillating body to generate electricity. The devised devices excel in harnessing wave energy across a wide spectrum of frequencies and are well-suited for deployment in both shallow and deep ocean waters.

Abstract: Techniques are disclosed herein for minimizing movement of an offshore wind turbine. Using the technologies described, a wind turbine may be mounted on a marine platform that is constructed and deployed to reduce environmental loads (e.g., wind, waves, . . . ) on the platform in both shallow and deep water. In some configurations, a fully restrained platform (FRP) is configured to support a wind turbine. According to some examples, moorings are attached to the FRP and/or the structure of the wind turbine structure to reduce movement in six degrees of freedom.

Abstract: Various information systems may benefit from the appropriate simplification of data structures and processes. For example, certain health information systems may benefit from dimension reduction of claims data. A method can include creating a tensor to organize data. The method can also include conditionally reducing the size of that tensor in order to more effectively apply machine learning.

Abstract: A moving window history of at least one previous data address accessed by a processor is maintained, the at least one previous data address in the history each being associated with an index. A difference between a current data address and one of the at least one previous data address in the history is determined. The difference and the index associated with the one of the at least one previous data address in the history are provided as a representation of the current address.

Abstract: A method and apparatus for securing a buoyant, surface structure in deepwater, such as those used in offshore oil and gas drilling and producing, is disclosed. The surface structure is water surface piercing or fully submerged. Buoyancy tanks inside the surface structure are used as liquid vibration dampers to enhance the motion performance. All tethers are sufficiently taut and some or all of them are inclined. The attachment points of the tethers on the surface structure are at same or different elevations. An alternative attachment method, named as “single tether-multiple attachment leg”, is also disclosed. The tether system provides stiffness in both vertical and horizontal direction so that all six degrees-of-freedom motions of the structure, namely, surge, sway, heave, roll, pitch, and yaw are constrained with stiffness. This fully constraint platform (FCP) has minimum motion in winds, currents, swells, and surface and internal waves, and therefore has many practical uses, as outlined herein.
