The different advantageous embodiments provide an apparatus comprising a sensor system, a computer system, and a satellite transceiver. The sensor system is configured to generate data about a vessel and an environment around the vessel. The computer system is connected to the sensor system. The computer system is configured to receive the data from the sensor system, generate vessel information about the data, and send the vessel information to a remote location. The satellite transceiver is connected to the computer system. The satellite transceiver is configured to send the vessel information to and receive other information from the remote location.

An offshore floating production, storage, and off-loading vessel has a hull of generally cylindrical or polygonal configuration surrounding a central double tapered conical moon pool and contains water ballast and oil and / or liquefied gas storage compartments. The exterior side walls of the polygonal hull have flat surfaces and sharp corners to cut ice sheets, resist and break ice, and move ice pressure ridges away from the structure. An adjustable water ballast system induces heave, roll, pitch and surge motions of the vessel to dynamically position and maneuver the vessel to accomplish ice cutting, breaking and moving operations. The moon pool shape and other devices on the vessel provide added virtual mass for increasing the natural period of the roll and heave modes, reducing dynamic amplification and resonance due to waves and vessel motion, and facilitate maneuvering the vessel. A disconnectable turret buoy at the bottom of the moon pool connects risers and mooring lines.

A multihull hydrofoil watercraft incorporates a stabilization system wherein the buoyancy of the hulls is used as a sensing and control mechanism for the hydrofoils. The use of hull buoyancy to adjust the hydrofoil lift provides for automatic control of altitude, pitch and roll, and allows the craft to accommodate varying weather and sea conditions while providing a smooth ride for passengers. The stabilization technique eliminates the need for extraneous sensing mechanisms placed in or on the water surface which are subject to fouling, damage, or disruption by localized surface disturbances.

A system is disclosed for dynamically stabilizing a ship in high sea states. A six degree-of-freedom robotic arm is attached to the ship, and a thruster is located at the distal end of the manipulator. The manipulator is be used to orient the thruster to counteract wave forces that act against the ship's hull in real time. This active balancing technique can be used to keep the ship substantially erect in rough seas by making continual corrections to the ship's body attitude. The center of gravity and the center of buoyancy of the ship are utilized, along with a precisely oriented and controlled thrust at the end of the manipulator, to optimally control the ship's state against impending waves.

The invention relates to an arrangement (1) for dynamic control of running trim and list of a boat, said boat having at least one hull (2) with a stern (3), said arrangement (1) having a housing member (9), an interceptor member (5), an actuating means (10), a drive unit (7) operated by a power supply means (8), and a guiding means (22), said guiding means (22) being arranged to guide said interceptor member (5) between a first end position and a second end position, said actuating means (10) being arranged to displace said interceptor member (5) in a movement between said first and second end positions in relation to said housing member (9) by being driven by said drive unit (7), and said housing member (9) fully enclosing said interceptor member (5) in said first end position and partially enclosing said interceptor member (5) in said second end position.

The present invention is directed to novel methods and apparatus for the design, installation, use, recovery, and reuse of a Self Supporting Riser (SSR) for wells that are not under a platform. The SSR of the present invention uses standardized joints that can be recovered, potentially warehoused, and recombined in different configurations for different purposes or locations. Emphasis is on methods and apparatus that use relatively small vessels subject to high motions in the installation, use and recovery of the SSR. The SSR is adapted for high current and / or deep water applications for purposes of downhole well intervention and subsea equipment installation. In contrast to the apparatus and processes of the prior art, this invention addresses a comprehensive system design.

Wakeboarding performance is improved using a vessel which is fitted with a skeletal towing frame having spaced supports attached on opposite sides of the vessel while coupling upper extremities of the supports with a horizontal bridging portion, to which a tow rope attachment point is fitted.

An integrated safety accessory arrangement and components for users of personal watercraft such as kayaks, canoes, and catamarans. The arrangement is comprised of safety related components providing the following integrated features: alternate personal hydration for paddlers accommodating common beverage containers as well as compartments for contemporary sports reservoirs with hull and hatch cover ports to route and seal the attached drinking tubes for use underway, and mounting and storage for navigation and communication devices such as marine compasses, GPS, VHF and FRS radios, cell phones, and the like. All are accessible while underway; and one-handed kayak skirt-on use of common portable manual pump with in-hull pump storage holder.

A vehicle includes a submersible housing and a propulsion mechanism, which is coupled to drive the housing over an interior surface of a container in which the housing is submerged. A hollow tube is fixed to the housing and is configured to be filled with a fluid having a first specific gravity. One or more objects, which have a second specific gravity that is less than the first specific gravity, are contained within and capable of moving inside the hollow tube so as to stabilize the housing in response to changes of an angle of the interior surface over which the vehicle travels.

A target biokill of species for water to be discharged from a ballast tank of a sea faring vessel is determined. A diverted portion of sea water is regulated prior to charging the water into the ballast tank. Regulation of the diverted portion of water and a rate of injection of the ozone into the portion are adjusted to attain the target biokill. Then ozone at the determined rate into the regulated diverted portion to attain the target biokill when the portion is recombined into the water for charging to the ballast tank.
