    • There is disclosed a system and method for forecasting the positions of marine vessels. In an aspect, the present system is adapted to execute a forecasting algorithm to forecast the positions of one or a great many marine vessel(s) based on one or more position reporting systems including coastal and satellite AIS (S-AIS) signals or LRIT received from the vessel. The forecasting algorithm utilizes location and direction information for the vessel, and estimates one or more possible positions based on previous paths taken by vessels from that location, and heading in substantially the same direction. Thus, a body of water can be divided into "bins" of location and direction information, and a spatial index can be built based on the previous paths taken by other vessels after passing through that bin. Other types of information may also be taken into account, such as ship-specific data, nearby weather, ocean currents, the time of year, and other spatial variables specific to that bin.

    • The invention is concerned with a computer-implemented method to produce a model that predicts the performance of a ship. The method comprises the steps of creating an initial model for simulating the performance of the ship by means of relationships between factors related to the ship during operation and parameters presenting primary dynamic input data that depend said factors depend on. Measurement results are obtained from sensors during the operation of the ship for producing a set of new dynamic input data to be used in the model. A simulation result for the ship performance is calculated by using said produced input data in said model instead of the primary dynamic input data. The simulation result is then compared to the actual ship operation. If the difference between the simulation result and the actual operation exceeds defined threshold criteria, the model is improved by repeatedly producing new sets of dynamic input data to be used in the model by means of new measurement results until defined quality criteria are met. The invention is also concerned with a system and that performs such a method and a computer program.

    • A computer implemented method for guiding an under-actuated marine surface vessel in tracking a desired trajectory comprises expressing a predetermined vessel trajectory as a set of straight line segments, determining a desired current line segment, and determining the vessel's current position. A cross-track error and the derivative of the cross-track error are then determined. Next, a radius R of the line-of-sight (LOS) circle using a newly introduced exponential function is determined. Intersection points M and N between the LOS circle and the current desired line segment are determined. A desired heading angle is determined as the angle between the line of sight and a predetermined fixed reference line. A drift detection algorithm is built into the proposed guidance scheme to detect situations whereby the ship moves parallel to its desired trajectory for an extended period of time without being able to correct for the cross track error. The drift algorithm continuously monitors the ship motion relative to the desired trajectory and, upon drift detection, modifies the desired heading angle to enable the controller to compensate for the ship drift. This allows the ship to accurately track its desired trajectory.
