Offshore floating production, storage, and off-loading vessel for use in ice-covered and clear water applications
InactiveUS20090126616A1Reduces dynamic amplificationReduce resonanceProtective foundationMovement controllersResonanceBuoy
An offshore floating production, storage, and off-loading vessel has a monolithic non ship-shaped hull of polygonal configuration surrounding a central double tapered conical moon pool and contains water ballast and oil storage compartments. The exterior side walls of the 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 capable of 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. The vessel may be moored by a disconnectable turret buoy received in a support frame at the bottom of the moon pool and to which flexible well risers and mooring lines are connected.

Wake enhancement assembly
InactiveUS6427616B1Inexpensively retrofittedLarge weighting factorWave generating vesselsWater sport boardsBiomedical engineeringVALVE PORT
The subject invention is a wake enhancement assembly to vary a configuration of a wake produced by the hull of a boat. The assembly preferably includes three or four fluid chambers adapted to be disposed within the hull of the boat. The fluid chambers can be filled to provide added weight in selected areas of the hull. The added weight alters how the hull rides within a body of water and as such will alter the wake of the boat. A plurality of hoses are mounted to and in fluid communication with the fluid chambers for selectively filling and draining the fluid chambers. The assembly is characterized by a manifold having an inlet and a plurality of outlets. Each of the outlets has a valve disposed in fluid communication therewith. The filling hoses are connected to the outlets such that the valves of the manifold control a flow of fluid to and from the fluid chambers independently of each other. The valves and manifold electronically and remotely control the selective filling and draining of the fluid chambers.

Gunwale attachable dry box for small watercraft
A dry storage box is held by a clamping device at a longitudinal location along the length of the small watercraft. Dry box provides water tight storage compartment with a hinged lid and latches for storing miscellaneous personal valuables and belongings. The clamped water tight box, in the event of capsize, remains secured to the gunwale, and thus valuables and belongings remain safe, dry and in one location. Incidentally provided are added buoyancy to the vessel in the event of a capsized condition, and when box is in normal use the longitudinal location allows free movement of the occupants about the small watercraft.

Multihull hydrofoil watercraft
InactiveUS7743720B1Reduce angle of attackReduce lifting forceVessel partsVessel movement reduction by foilsAutomatic controlAutomatic train control
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 trash skimmer work boat collects and discharges debris from the front or bow. A storage conveyor positioned approximately amidships and along the center line, and is mounted to the hull on a slide or track arrangement that permits fore and aft motion. A collection and discharge conveyor is mounted at the bow portion of the hull. The forward conveyor can be oriented in a trash collection position or in a trash discharge position. The storage conveyor is brought sternward so that there is clearance for the proximal end of the forward conveyor to be raised or lowered, and then is brought back forward so that the storage conveyor is in position to receive debris or to discharge it. Auxiliary floats at the sides of the boat hull provide additional buoyant support for the front conveyor, and are detachable so they can be removed for road transport of the boat.

Gyrostabilizer for small boats
InactiveUS20050076726A1Large counter roll torqueShorten the timeMechanical apparatusVessel movement reduction by gyroscopesMomentumAngular velocity
A gyrostabilizer system that counteracts the natural rolling motion of a small boat or vessel. The invention constitutes an improvement in prior art systems of this type in that the system weighs less because it has a much lighter rotor made of composite materials spinning at much higher speeds. The gyrostabilizer system includes a lightweight rotor spinning at very high speeds to attain a large angular momentum. The mass of the rotor is concentrated away from the spin axis of the rotor to maximize angular momentum while minimizing weight. The rotor is mounted in a frame that, in turn, is mounted on gimbals so that the frame can be rotated about an axis that is normal to the longitudinal roll axis of the vessel. When the rotor is rotated about the gimbals, a torque is created that opposes the torque created by the sea and reduces the rolling motion of the vessel. The rotor may be mounted in an evacuated chamber to reduce air drag. Rotation of the rotor frame around the gimbal axis is controlled by an active servo system using information provided by roll angular position and angular velocity sensors
