A fin stabilizer for stabilizing watercraft includes a pivotable stabilizer fin and a receiving space for receiving the stabilizer fin. The stabilizer fin is shiftable from a retracted state in which the stabilizer fin is received in the receiving space to an extended state in which the stabilizer fin extends from the receiving space. Also at least one flexible cover element for at least partially covering an opening of the receiving space, through which opening the stabilizer fin enters and exits the receiving space during retracting and extending, respectively. The stabilizer fin does not contact the at least one cover element when shifting from the retracted state to the extended state.

A boat lift having a plurality of flotation tanks positioned under each of opposite sides of a frame of the boat lift. Trunk lines receive water through a port near the rear of the trunk lines, and communicate water into a plurality of flotation tanks. Water flow is regulated so that the plurality of the tanks fill relatively evenly to maintain a surface of the boat lift that is generally horizontal at all times. Hingeable connection of the dock to a bulkhead, along with lateral stabilization, participate in maintaining a generally horizontal attitude for the boat lift. Water is expelled from the plurality of flotation tanks by pumping water from the flotation tanks, allowing the frame of the boat lift to rise.

A method is described for providing an alert when the motion of a ship indicates a potential of sloshing damage from liquid cargo being transported by the ship. The method includes calculating, with a processing device, a natural period for the tanks holding the liquid cargo based on the configuration and fill levels of the tanks, receiving, at the processing device, data describing the actual or predicted motion of the ship with respect to three orthogonal axes, determining, with the processing device, a proximity of the natural period of the tanks to a period defined by the actual or predicted motion of the ship, and providing an alert to a user if the proximity in periods is within a threshold value.

A device for arranging a profiled element on the bow side of a water vehicle and a water vehicle having a wind-impacted element. The device has at least one profiled element (40, 40.1, 40.2) and means for arranging the at least one profiled element (40, 40.1, 40.2) on the bow (20) of a water vehicle (10, 100), wherein the profiled element(s) (40, 40.1, 40.2) is/are or can be supported about a pivot axis (S) which is parallel, preferably horizontal, to the midship plane, wherein the profiled element(s) (40, 40.1, 40.2) can be or is/are connected to a wind-impacted element (14) at a leading point (43) of a wind-impacted-element-driven water vehicle (10, 100) by means of a connecting device (42), in particular by means of a whippletree (42.
摘要:
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. An adjustable water ballast system induces heave, roll, pitch and surge motions of the vessel to dynamically position and maneuver the vessel. 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 user floatation system for boating safety. There is included in the system a boat, having a seat for a user, and a rear and forward section located behind and in front of the user respectively. There is also a flotation system, including float device, designed to be placed in the water on at least one side of the boat; and frame system, coupled to the boat at one end and to the float device at an opposite end, designed to hold the float device in a 1) deployed position where the float device is held in the water when a user is in the seat, and 2) partially deployed position where the float device is held a distance above the water level when a user is in the seat sufficient to enable the user to tip the boat a certain angle from a level position but to assist in preventing the boat from tipping completely over.
摘要:
The present invention discloses a gravity center adjustment device for a wind turbine installation vessel, with the gravity center adjustment device (2) fixedly mounted to the outside of the vessel body (4) of the wind turbine installation vessel. The existence of the gravity center adjustment device (2) according to the present invention is independent from the vessel body and no longer limited by the size of the installation vessel and the size of the ballast bank provided in the vessel body of the wind turbine installation vessel. The size of the gravity center adjustment device (2) may be set as desired so that the adjustment ability of the gravity center adjustment device can be changed, whereby its ability for adjusting gravity center of the wind turbine installation vessel can be improved and the stability of the wind turbine installation vessel can be improved. Therefore, the wind turbine installation vessel can operate in an environment of poor weather condition, so that the operation efficiency can be improved and the cost of constructing a wind power plant on the offshore can be reduced. The present invention also discloses a wind turbine installation vessel including the above-mentioned gravity center adjustment device (2).
