摘要： A method for controlling a propulsion operation of a propulsion unit to reach a desired speed of a marine vessel. The method comprises obtaining a target speed configuration indicating the desired speed of the marine vessel, obtaining a current speed value associated with a current speed of the marine vessel, obtaining a fill level value associated with a fill level of one or more ballast tanks of the marine vessel, and controlling the propulsion operation of the propulsion unit to reach the desired speed based on the target speed configuration, the current speed value, and on the fill level value.

摘要： The present disclosure relates to a propulsion control system (30) for controlling a marine vessel (10) comprising at least four propulsion units (20, 22, 24, 26). The marine vessel (10) comprises a longitudinal centre line (L) and a transversal line (T). The transversal line (T) extends in a direction perpendicular to the longitudinal centre line (L) and also extends through the steering axis of the aftmost of the propulsion units. The marine vessel (10) comprises four quadrants (I, II, III, IV) defined by the longitudinal centre line (L) and the transversal line (T) wherein a first (I) and a second (II) quadrant are located on the same side of said longitudinal centre line (L). When a combined sway and yaw motion is desired, the thrust of one propulsion unit is directed towards the second (I) quadrant, and the thrust of the other propulsion units is directed towards the first (II) quadrant.

摘要： A boat basically includes a hull, at least one propulsion unit, a heading sensor, a position sensor and a controller. The at least one propulsion unit is movably mounted to the hull, and has a propulsion axis. The heading sensor is configured to detect a heading of the boat. The position sensor is configured to detect a position of the boat. The controller is programmed to turn the at least one propulsion unit relative to the hull such that the propulsion axis moves away from a center point of the boat to correct the heading of the boat upon determining that the boat is drifting in a drift direction based on detection results of the heading sensor and the position sensor.

摘要： A method for a propulsion arrangement (101) for providing propulsive power to a marine vessel (1), the method comprising the steps of: —determining (S1) whether the vessel (1) is running by means of the propulsion arrangement at a constant vessel speed, —storing (S3) a value (V1) of the constant vessel speed, —detecting (S4) a value (n1) of a rotational speed of a rotatable part (102) of the propulsion arrangement while the vessel is running at the constant vessel speed, —storing (S5) the detected rotational speed value, —subsequently controlling (S6) the propulsion arrangement so as to change the vessel speed, —subsequently repeating (S7-S11) the steps of determining whether the vessel is running at a constant vessel speed, storing a value (V2-V4) of the constant vessel speed, and detecting and storing a value (n2-n4) of the rotational speed of the rotatable part, to obtain a plurality of stored pairs of vessel speed values and rotational speed values, and —creating (S12) based at least partly on the stored pairs of values a correlation record (126) correlating vessel speed values with rotational speed values.
