Wakeboat fluid housing compartment fluid level sensing assemblies are provided. The assemblies can include: a wakeboat having a hull; a fluid housing compartment associated with the hull; a nonconductive sensor chamber positioned within the fluid housing compartment of the hull; and at least a pair of conductive electrodes associated with the sensor chamber, at least one of the pair of conductive electrodes being positioned within the nonconductive sensor chamber and electrically isolated from fluid within the fluid housing compartment. Methods for sensing a fluid level within a fluid housing compartment aboard a wakeboat are also provided. The methods can include: maintaining fluid communication between the fluid level within the fluid housing compartment and a sensor chamber; and determining the electrical communication between at least a pair of electrodes operatively associated with the sensor chamber.

A method for controlling an inclination of a floating wind turbine platform to optimize power production, or to reduce loads on the turbine, tower, and platform, or both, includes receiving data associated with the inclination of the floating wind turbine platform and wind speed and direction data. An angle of difference between the turbine blade plane and the wind direction is determined, where the angle of difference has a vertical component. A platform ballast system is then caused to distribute ballast to reduce the vertical component to a target angle chosen to optimize power production, or reduce turbine, tower, and platform loads, or both.

An unmanned vehicle including a vehicle body, propulsion system, maneuvering system, vehicle control system, rack, sensor, and a power supply. The vehicle control may be used to control the unmanned vehicle in combination with the propulsion and the maneuvering system. The rack may include a retractable mount that may move between a down position and an up position. The sensor system may include a plurality of transient object detection sensors. The plurality of transient object detection sensors may include a sensor adapted to detect an item of interest and may provide an item of interest signal to the vehicle control system. The vehicle control system may identify an item of interest classification and may provide a classification signal. The classification signal may be determined by the item of interest classification and may be utilized to avoid detection of the unmanned vehicle by the item of interest.

A control system for stabilizing a floating wind turbine is provided. The control system includes a measuring device configured for measuring a wind field and a wave field, a determining device wherein the determining device is configured for determining an excitation frequency spectrum of the floating wind turbine on the basis of the measured wind field and/or the wave field and/or a current floater pitch angle of the floating wind turbine, and wherein the determining device is further configured for determining a balanced state of the floating wind turbine, wherein in the balanced state a natural frequency is outside of the excitation frequency spectrum and/or the current floater pitch angle is equal to a pre-defined floater pitch angle. The control system further includes an adjustment device which is configured for manipulating the current floater pitch and/or the natural frequency until the balanced state is met.
