A system includes a memory device and a processing device. The processing device is operatively coupled to the memory device to perform operations, including receiving a set of data associated with operation of a self-propelled vehicle, obtaining power demand data based on the set of data, and utilizing the power demand data within one or more applications related to the self-propelled vehicle.

Diagnostics systems and methods for on-board raw water systems of watercraft. Flow or pressure changes are detected at one or more locations along a flow path of the onboard raw water system. A fault is diagnosed based on a type of flow change or pressure change detected. An alert is issued regarding the fault and/or a remedial action is suggested for correcting the fault.

Provided is a device configured to determine a power capacity of a battery of a vehicle, predict a first set of values indicative of amounts of power to be stored during a time interval by the battery, the power being generated by a renewable energy generator carried by the vehicle, and predict a second set of values indicative of amounts of energy to be consumed from the battery during the time interval based on previous energy consumption by the vehicle. The device is also configured to determine a score based on the power capacity, the first set of values, and the second set of values. The system is also configured to determine whether the score satisfies a threshold and, in response to a determination that the score satisfies the threshold, activate an internal combustion engine to charge to the battery.

An apparatus, method and system for real-time monitoring of underwater risers, cables, and mooring lines based on a Kalman filter. In an embodiment, the system is formed with sensors configured to sense an inclination of a riser segment between riser nodes of the riser between the upper end and the lower end. A data processing system is configured to employ a Kalman filter algorithm to produce real-time estimates of a deformed shape and a stress of the riser segment using the sensed inclination between the riser nodes.

An apparatus for judging presence or absence of an abnormality of a marine vessel includes a controller configured or programmed to function as an estimating unit to estimate a marine vessel speed and a pitch angle of a hull of the marine vessel based on a propulsion force of a marine vessel propulsion device and an attitude of the marine vessel propulsion device and a judging unit, and a measuring unit to measure an actual marine vessel speed and an actual pitch angle. The judging unit judges the presence or absence of the abnormality based on at least one of a comparison result between the estimated marine vessel speed estimated by the estimating unit and the actual marine vessel speed measured by the measuring unit or a comparison result between the estimated pitch angle estimated by the estimating unit and the actual pitch angle measured by the measuring unit.
