  • Publication number: 20230205207
    Abstract: A method to control a marine vessel comprising two or more drive units. The method involves registering an operating command indicating a requested sideways or bow bollard push function; detecting a current vessel position; registering the current vessel position as a desired vessel position; executing the requested bollard push function; and monitoring the current vessel position in order to detect a deviation relative to the desired vessel position. If it is detected that a deviation between the desired vessel position has exceeded a predetermined value, then the requested bollard push function is deactivated. The disclosure further relates to a control unit arranged to control a marine vessel and a marine vessel comprising such a control unit.

  • Publication number: 20230195117
    Abstract: The disclosure relates to a method and a control unit to control a marine vessel comprising two or more drive units. The method involving the steps of registering an operating command indicating a requested vessel direction and plotting a course represented by a reference line for the requested vessel direction from an initial position. It is then monitored if the vessel has deviated from the reference line and if a deviation from the reference line is detected, then a value for current vessel speed is detected. The detected vessel speed value is compared to a predetermined reference speed value to determine if the current vessel speed value is within a high speed interval or a low speed interval relative to the reference speed value. Depending on the determined speed interval the vessel is controlled according a low speed control strategy; or a high speed control strategy in order to move the vessel from a current vessel heading to the reference line and the requested vessel direction.
