A technique capable of determining a suitable or optimum exclusive region (bumper) setting value and improving the accuracy and others of ship collision avoidance support and automatic ship maneuvering as a result is provided. A ship maneuvering calculation device 1 calculates setting information of an automatic ship collision avoidance program 3 for achieving a function of an automatic ship collision avoidance device 2 of a vessel. The ship maneuvering calculation device 1 generates a plurality of exclusive region values 103 that are different in at least a shape and a size as parameter values for an exclusive region set around a vessel, repeatedly executes simulation calculation using the automatic ship collision avoidance program (a copy 13) while changing a condition 102 and the parameter values, calculates an evaluation value 105 corresponding to the parameter value, based on the result of the simulation calculation, determines an optimum value 106 of the exclusive region, based on the evaluation value, and sets the optimum value 106 of the exclusive region to the automatic ship collision avoidance program 3.

A ship assignment device acquires voyage schedule information including an operation time schedule and a sailing route of a voyage. The ship assignment device acquires, from a database, weather information related to the operation time schedule and the sailing route included in the schedule information. The ship assignment device acquires information regarding variations in fuel consumption rate from a database that stores the information for each of plural ships. On the basis of the acquired weather information and acquired information regarding each ship, the ship assignment device calculates the fuel consumption for when each ship sails on the sailing route included in the acquired voyage schedule information in accordance with the operation time schedule included in the voyage schedule information. On the basis of the calculation result, the ship assignment device outputs information identifying plural ships.

Techniques for providing instructions to an operator of a sea vessel via a computing device are described. The computing device can request, from another computing device, instructions regarding one or more of an intended course and action plan for the sea vessel, which can include at least one navigational instruction and/or deployment instruction. The computing device can send data to a display device to cause a prompt to be displayed. The prompt can include options regarding the at least one instruction. The computing device can send state information of the sea vessel to the other computing device. The state information can include the received input and location information of the sea vessel. Additionally, data can be received by the computing device from a shore based operator and data can be sent to one or more clients on shore.

Systems and methods for conveniently providing anchoring assistance onboard a watercraft are provided herein. An example system includes a display and a processor in communication with a marine system. The processor is configured to receive marine data from the marine system and/or one or more user inputs and cause the display to show one or more anchoring locations with visual indications of the anchorage quality index based on at least the marine data and/or user inputs. The one or more anchoring locations may be shown as a heat map overlaid on a map. The system may use real-time marine data, environmental data, weather data, tide data, etc. to dynamically adjust the anchoring locations and anchorage quality index. The system may enable convenient and helpful suggestions and notifications to the user when anchoring a watercraft. Some examples provide automatic deployment of an anchoring system and monitoring of a current anchoring.
