  • Patent number: 11352117
    Abstract: Apparatus and associated methods relate to configuring a watercraft propulsion system and control surface to generate a higher rate flow and a lower rate flow governed by the watercraft's yaw slip angle, adjusting the rate difference between the higher rate flow and the lower rate flow based on adjusting the yaw slip angle determined as a function of the control surface position and the propulsion system thrust vector, and directing by the watercraft the higher rate flow to converge with the lower rate flow to create a wave. The propulsion system may be a plurality of independently adjustable propulsion methods permitting propulsion system differential thrust vector adjustment. The control surface may be adjustable 360 degrees in the plane of the watercraft longitudinal axis. The yaw slip angle may be adjusted based on sensor information. Exemplary implementations may increase wave quality and improve maneuverability of a watercraft configured to create waves.

  • Patent number: 9555870
    Abstract: A method for heating a cargo on a watergoing vessel using an energy source (such as a heat source) on another watergoing vessel. The vessels may be underway. The energy may be transferred to the cargo via energy umbilicals configured to carry energy in a transfer fluid. The transfer fluid may be circulated in a cargo heat exchanger configured to move energy into the hot cargo. The energy source on the another watergoing vessel may be a propulsion motor, exhaust heat, or non-propulsion heat source. The method may include heating the hot cargo. The method may also include switching between heat sources when both vessels are configured to heat the hot cargo.

  • Patent number: 9475566
    Abstract: A ballast water treatment device includes a ballast water treatment line, a pump for drawing and pressure feeding treatment target water, a filter, an ultraviolet reactor for irradiating filtrated treatment target water with ultraviolet, a ballast tank for storing treated water having been treated with ultraviolet, and an outboard discharger, and the pump, the filter, the ultraviolet reactor, the ballast tank, and the outboard discharger are provided on the ballast water treatment line. Treatment target water drawn for a predetermined period from start of drawing treatment target water is not caused to pass through the filter and the ultraviolet reactor but is discharged outboard by the outboard discharger, and discharging outboard by the outboard discharger is stopped at elapse of the predetermined period and treated water having been filtrated by the filter and having been treated with ultraviolet by the ultraviolet reactor is poured into the ballast tank.

  • Patent number: 9387913
    Abstract: Systems and methods may include an enclosable, modular floating dry dock, which may comprise a plurality of floodable flotation modules coupled to a central support member at spaced intervals, such that gaps are formed between successive flotation modules. Each gap may be spanned by a deck and/or wall. A working volume may be defined between an interior of the floating dry dock and a supported watercraft. The working volume may be environmentally enclosed by drapes coupled to the dry dock.

  • Patent number: 9359048
    Abstract: A ship whereby the hull and the mechanical propulsion device are designed such that the Froude number is larger than 0.5. In the aft ship the hull has a bottom with V-shaped bottom surfaces with a deadrise angle that is less than 40 degrees and the hull has substantially vertical sides. In the hull are a passenger compartment and a trim tank. The trim tank volume is such that the weight of a filled trim tank is more than 30% of the weight of displacement of the hull with an empty trim tank, filling the trim tank with water increases the amidships immersed width with at least 10%, and the bottom surfaces have bilge keels fully immersed when the trim tank is filled with water and the bilge keels are at least in part above the water level when the trim tank is empty.

  • Patent number: 9329039
    Abstract: This invention provides a new category of inertial sensors (linear and angular accelerometers, gyroscopes, inclinometers and seismometers) called Molecular Electronic Transducers (MET). Unlike other inertial sensors, MET sensors use a liquid electrolyte as their inertial mass. The sensors do not contain any precision mechanical parts or springs, and are relatively simple and inexpensive to manufacture.

  • Patent number: 9316209
    Abstract: A movement inhibiting apparatus for a floating offshore wind turbine and a floating base with the apparatus. The movement inhibiting apparatus for the floating offshore wind turbine comprises at least one layer of an annular shake-reducing panel placed horizontally and surrounding the floating base. A plurality of shake-reducing fins is further arranged on the shake-reducing panel. The plurality of shake-reducing fins comprises a first set of shake-reducing fins arranged on one side of the shake-reducing panel and the shake-reducing fins of the first set are spaced apart vertically around the floating base. The movement inhibiting apparatus for the floating offshore wind turbine can effectively inhibit the movement of the floating wind turbine and is of low cost.

  • Patent number: 9315237
    Abstract: Wakeboarding performance is improved using a vessel having an operator station located generally amidships, a vertical support unit fitted across a beam of the vessel near the operator station, and adjustable ballast. An upper portion of the vertical support is at a height substantially above a level of the operator station, and a container is onboard and proximate the starboard and port sides, wherein water from a body of water within which the vessel is operating is directed into the container for weighing down a stern of the vessel to provide the ballast so as to modify a wake created for a wakeboarder or the like being towed by the vessel using a tow rope attached to the upper portion of the vertical support.

  • Patent number: 9254896
    Abstract: A ballast system and method use a situational adaptive approach to measure, control and monitor the level of liquid in an onboard ballast tank. A baseline level of liquid in the tank, established while the watercraft is static, is stored in memory associated with a controller. While the watercraft is moving, the controller monitors pump conditions, e.g., run time, flow, vacuum, etc., and extrapolates the amount of water added to or drained from the tank. The baseline level and extrapolated added/drained amount are added to accurately determine the true liquid level in the tank. That information is displayed to the watercraft operator. The system can automatically adjust watercraft attitude by adding/draining water from the ballast tank based on preset values to provide a desired wake. The system can display ballast levels in volume, percentage of full, and weight; and can provide estimated times to achieve preset levels, empty or full.
