An anti-rolling gyroscopic stabilizer for boats provides a stationary frame fixed to the hull, an oscillating frame and a flywheel. The angular velocity of oscillation of the oscillating frame is limited by hydraulic dampers. Elastic return elements are coupled to the dampers and urge the oscillating frame so as to orient the axis of rotation of the flywheel towards a given angular position in which the gyroscopic device acts with maximum efficiency.

Some implementations feature a mast stabilizing device that includes a mast comprising a first portion and a second portion, a sensor coupled to the first portion of the mast, and a pivot structure coupled to the mast. The pivot structure is configured to allow the mast to pivot in the mast stabilizing device. The mast is coupled to the pivot structure so as to pivot along a pivot portion of the mast. The mast stabilizing device also includes a mass coupled to the second portion of the mast. The mass is configured to counteract a force applied to the first portion of the mast. The mast stabilizing device further includes a platform coupled to the pivot structure, the platform configured to operate on a body of water. In some implementations, the pivot structure is a gimbal device.

A floating wind turbine platform includes at least three stabilizing columns, where each stabilizing column has an internal volume for containing ballast. The floating wind turbine platform also includes a tower having mounted in vertical alignment over one of the columns, a turbine rotor coupled to an electrical generator mounted proximate to the upper end of the tower, main beams interconnected to the stabilizing columns, and water-entrapment plates attached to the lower ends of the stabilizing columns. The floating wind turbine platform further includes a ballast control system including an alignment sensor configured to detect a rotation of the tower, and a controller coupled to the alignment sensor for directing a transfer of the ballast from an internal volume of one column to another column upon the alignment sensor detecting rotation of the tower to adjust a vertical alignment of the tower.

A transportable watercraft stabilization apparatus includes a stability device configured to impart a stabilizing torque to a watercraft when mounted on the watercraft and a transportable containment device containing the stability device therein. The transportable containment device includes a first attachment apparatus for releasably attaching to a transporting means and a second attachment apparatus for releasably attaching to a coupling device onboard a watercraft. Furthermore, the transportable watercraft stabilization apparatus includes a power source configured to provide power to the stability device for generating the stabilizing torque. The watercraft stabilization apparatus is transportable between a first watercraft and a second watercraft for providing on-demand stabilization to the second watercraft.

A multi-hulled water craft is disclosed. The water craft has a body, one left hull and one right hull, each hull connected to the body by respective locating means which permits at least substantially vertical and pitch motion of the respective hull relative to the body. The multi-hulled water craft also has a suspension system including at least a front left modal support means and a back left modal support means for providing at least partial support of the body with respect to the left hull, and at least a front right modal support means and a back right modal support means for providing at least partial support of the body with respect to the right hull. The suspension system further includes interconnection means connected to the modal support means to provide different stiffness between motions in at least two of roll, pitch, heave and warp suspension modes.

The present invention provides methods and apparatus for reducing sinkage and wetted surface, and thus hydrodynamic drag of a high-speed boat through the generation of aerodynamic lift while decreasing overall aerodynamic drag. At least one lift-generating front wing proximate a bow section of the boat with at least one corresponding front air channel may be provided. At least one lift-generating rear wing proximate a transom section of the boat with at least one corresponding rear air channel may also be provided. At least one of the wings may be adjustable to generate aerodynamic lift with one of: (1) a neutral; (2) a transom-lifting; and (3) a bow-lifting pitching moment about a center of inertia of the boat. At least one wing proximate the leading edge of the tunnel of a multi-hull boat may be provided to increase the operational envelope.

A device (10) for orientating a load to be suspended and moved by a crane includes a flywheel (11) mounted for rotation in a housing (14). A turntable (17) is pivotally connected to the housing (14) and is drivable relative to the housing using a driven worm gear (23) meshing with an annular set of teeth (22) on the turntable (17). The turntable has an axle (18) to which loads can be attached. When the flywheel (11) is spinning at high speed, it resists movement out of its plane of rotation so as to stabilize the cable in winds, etc. The flywheel (11) also allows the worm gear to react against it so as to turn the load relative to the flywheel (11). Maneuvering of the load is therefore made easier.
摘要:
Pitch of a vessel is controlled by trim tabs mounted on the stern of the vessel. The trim tabs are hinged along an axis transverse to the fore-aft direction of the vessel. A hydraulic system changes the plane of the trim tabs in response to a gyro-controlled servo system that senses changes in the fore-aft level of vessel. The trim tabs operate dynamically to maintain the fore-aft level substantially constant or within limits that effectively moderate the pitching motion of the vessel.
