Systems and methods for tracking vessel activities are described. An exemplar method of tracking vessel activities includes: (i) receiving data, using one or more devices, including vessel positioning data and/or time associated with one or more vessels traversing one or more paths on a body of water; (ii) deducing, using the data received from step (i), vessel attributes of one or more the vessels at certain positions and/or time along one or more of the paths; (iii) identifying, based on the vessel attributes of step (ii), one or more types of vessel activities of one or more of the vessels at the certain positions along one or more of the paths; (iv) parsing an electronic map of the body of water and land surrounding the body of water into discrete geographic zones; (v) grouping one or more types of vessel activities being carried out in each of the discrete geographic zones to arrive at one or more types of grouped vessel activities; (vi) causing to display or displaying one or more types of the grouped vessel activities that are being carried out in at least some of the discrete geographic zones.

Controlling marine vessel: obtaining motion data related to the marine vessel; obtaining an operation state related to one or more apparatuses exerting force from the marine vessel to ambient water; detecting a disturbance in one or more degrees of freedom affecting the marine vessel based on the motion data; and determining control data for the one or more apparatuses exerting force to attenuate the detected disturbance.

A method for the use in offshore crew transfer when transferring a person between a crew transfer vessel and a structure or vice versa where a prediction system for predicting vessel bow motion in response to sea waves detected by said wave detection device is used. An indicator is adapted to indicate a prediction of vessel bow motion below a first bow motion threshold value within a first predetermined time period based on said prediction system. The transfer of the person only takes place when said vessel bow motion is indicated to be below the first vessel bow motion threshold value within the first predetermined time period.

An apparatus (100) comprises at least one processor (110,210,530,550,385) and at least one memory (120,220) including computer program code. The memory (120,220) and the processor (110,210,530,550,385) are configured to, in respect of a ground-supported or liquid-supported body (401,411) travelling or to travel through a fluid, receive a determined magnitude and direction of a current within a forthcoming fluid zone (410,420), the magnitude and direction of the current determined from particulates suspended in the forthcoming fluid zone (410,420), and process the determined magnitude and direction of the current to provide for at least one of: a change in one or more fluid dynamical properties of the body (401,411), or navigation control of the body (401,411).

A collision information providing system provides information about a collision with a marine vessel, and includes a controller configured or programmed to function as a judging unit to judge whether or not there has been a collision of an object with a marine vessel, an information obtaining unit to obtain information about the collision when the judging unit judges that there has been the collision, and a providing unit to provide the information obtained by the information obtaining unit.

A navigation system includes a sensing device and an environment map creator. The sensing device generates environment information which indicates a shape of a shore arrival location. The environment map creator creates an environment map which indicates the shape of the shore arrival location based on the environment information.
