A method of maintaining positioning between vessels includes monitoring a relative position between a storage tank vessel and a shuttle tanker with a control system in operative communication with the vessels. Also included is inputting physical property data relating to the storage tank vessel and the shuttle tanker to the control system. Further included is processing environmental condition data with the control system. Yet further included is controlling at least one positioning action to be taken by the storage tank vessel and the shuttle tanker with the control system in response to positioning calculations conducted by the control system based on the physical property data and the environmental condition data. Also included is maintaining an angular differential within a predetermined limit with the at least one positioning action.

A marine vessel electronic display system includes a first display station that can include a mode selector for permitting selection of a first mode of operation and a processing system causing displays in the first display station to present information related to the selected first mode of operation. The marine vessel electronic display system may include a second display station that can include a mode selector for permitting a user to select a second mode of operation different from the first mode of operation and a processing system causing a display in the second display station to present information related to the selected second mode of operation.

A method for maintaining a marine vessel at a global position and/or heading includes receiving measurements related to vessel attitude and estimating water roughness conditions based on the measurements. A difference between the vessel's actual global position and the target global position and/or a difference between the vessel's actual heading and the target heading are determined. The method includes calculating a desired linear velocity based on the position difference and/or a desired rotational velocity based on the heading difference. The vessel's actual linear velocity and/or actual rotational velocity are filtered based on the roughness conditions. The method includes determining a difference between the desired linear velocity and the filtered actual linear velocity and/or a difference between the desired rotational velocity and the filtered actual rotational velocity. The method also includes calculating vessel movements that will minimize the linear velocity difference and/or rotational velocity difference and carrying out the calculated movements.

An object detection system for a marine vessel having at least one marine drive includes at least one image sensor positioned on the marine vessel and configured to capture an image of a marine environment on or around the marine vessel, and a processor. The object detection system further includes an image scanning module executable on the processor that receives the image as input. The image scanning module includes an artificial neural network trained to detect patterns within the image of the marine environment associated with one or more predefined objects, and to output detection information regarding a presence or absence of the one or more predefined objects within the image of the marine environment.

A navigation device is disclosed that provides navigational guidance to boats needing to cross a boundary line at a milestone event time. Port and starboard laylines and guidelines may be displayed with the boundary line using wind direction data. The port and starboard layline angles may change with the wind direction, while their lengths may represent a distance traversed by the boat tacking at the port and starboard layline angles for a target time period at a target speed. A predictor line may be displayed extending from the boat in the direction in which the boat is traveling and may have a length indicating a distance traversed by the boat at its current speed until the milestone event time. The predictor line length and color may provide feedback regarding whether the boat will cross the boundary too early or too late given its current speed and direction.
