    Abstract: This invention provides a vessel system and methodology that can be used to promote growth of phytoplankton in the oceans. Unmanned self-controlled wave-powered vessels are equipped with storage units for dispensing a fertilizer, and with sensors to monitor ocean conditions and effects. Fleets of vessels move autonomously by on-board processing of GPS and directional information, piloting a path that is coordinated by a central processing unit. The vessels travel through a defined target area, creating a detailed survey of chemical and biological characteristics that affect grown. The data are processed in a computer model to identify precise locations and precise amounts of fertilizer that will produce the best results. Projected benefits of fertilizing plankton include sequestering CO2 from the atmosphere, and enhancing the marine food chain to improve the fish stock in and around the treated area.

    Abstract: Disclosed herein is a semi-submersible offshore structure having storage tanks for liquefied gas, which is constructed so as to improve workability in marine offloading of the liquefied gas stored in the storage tanks while reducing an influence of sloshing. The offshore structure is anchored at sea and has liquefied gas. The offshore structure includes a storage tank storing liquefied gas, a plurality of columns partially submerged under the sea level and each having the storage tank therein, and an upper deck located on the plurality of columns to connect the columns to each other.

  • Patent number: 8561563
    Abstract: A mooring system may comprise a station keeping apparatus having a turntable rotatably mounted thereon. The station keeping apparatus is operable to movably couple to a first vessel and to a second vessel in a side-by-side configuration. The turntable is operable to freely rotate both the first and the second vessel about the station keeping apparatus. The station keeping apparatus is securable to the second vessel using a head mooring line having a length which is adjustable for aligning a heading of both the first and the second vessel with a prevailing weather direction. Further, the mooring system may comprise a rigid yoke or a soft yoke movably coupling the turntable to the first vessel for angular adjustment between the station keeping apparatus and a longitudinal center line of the first vessel.

  • Patent number: 8381669
    Abstract: The invention relates to a system for loading of hydrocarbons from a floating vessel, such as a FPSO or FSO vessel, to an export tanker, where the floating vessel is spread moored to a sea bottom, and where the export tanker during the loading phase is moored in such a way that the export vessel to a greater or less degree can weathervane dependent upon the prevailing weather, wave and/or wind conditions. According to invention the floating vessel at least at one end is provided with a rotatable deck which can be turned when the heading of the export tanker changes.

  • Publication number: 20120329345
    Abstract: An autonomous submersible vessel employs ambient wave energy to both propel itself and to generate required onboard electrical power. The vessel combines a ballast stabilized stator portion and a wave orbit driven rotor portion. Controlled resistance to their relative rotation occurs only when the horizontal component of wave orbit motion coincides with the desired direction of navigation, so increased hydrodynamic drag at that time acts to pull the vessel forward. The vessel incorporates a means to collect and preserve plankton samples. The vessel design enables alternate operation as an oceanographic glider to also navigate in deep water and in calm seas.

  • Patent number: 8328465
    Abstract: A method and associated vessel for transferring liquids from offshore tankers to an onshore storage facility. The system utilizes a flexible pipe that is heavier than the water it displaces, such that the flexible pipe sinks to the sea floor even when empty. The high weight and relatively small profile of the flexible pipe avoids the need for anchoring the pipe to the sea floor. The flexible pipe has a bending radius of no greater than five feet, such that it can be wound onto spools onboard the vessel, and can be rapidly deployed, retrieved, and reused in another location. The vessel containing the spools of flexible pipe is dynamic positioning capable, and contains the equipment required to establish a position onshore to receive the liquid being transferred; means to deploy, retrieve, and repair the flexible pipe; and means to receive liquid from a tanker vessel and pump that liquid through the flexible pipe to the onshore storage facility.

  • Patent number: 8322294
    Abstract: An offshore fresh water reservoir disposed a distance from the mouth of a river. The reservoir includes a flotation portion in the salt sea that supports a downwardly extending tubular skirt that defines a barrier. A transverse intermediate-density interface having a bulk density greater than fresh water and less than salt water is provided. The interface floats on the salt water and sinks in fresh water. In an embodiment the interface includes a plurality of balls filled with a liquid having a density corresponding to a mixture of salt water and fresh water. The reservoir is anchored in position, and includes a pumping means. In a reservoir system a curtain assembly directs the fresh water effluent to a floating blanket assembly, which further directs the effluent to a pipe that transports the effluent to the reservoir.
