[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system in which a marine vessel and a shore office are connected using satellite communication, and various information of the vessel can be browsed and managed collectively on the shore. The present invention relates to a ship operation management method and system capable of performing ship operation and preventive maintenance.

[0002]

2. Description of the Related Art In recent years, the deterioration of ship crew has become a problem in ship operation management, and the burden on ship management companies (shipping companies) on the shore side has increased accordingly. On the other hand, if a trouble occurs on the landside, even if the supervisor in charge receives notification from the ship, the information for judging countermeasures is scarce and accurate judgment is often difficult.

[0003] In the diesel engine support device described in Japanese Patent Application Laid-Open No. Hei 9-226688, data is transmitted and received between a ship and land, an abnormal state of the engine is analyzed by a land-side computer, and the analysis result is used as a question item. The system is used to send the information to the ship and the crew to check the relevant places and contact the land side. For transmission of data on the ship side, it is necessary to select and transmit transmission data on the ship. In such a conventional preventive maintenance of an engine unit, a crew member carries out the measurement and analysis on the ship, and it is necessary to transmit some request to the ship in order to obtain information on land.

In such a case, data transmission and reception are carried out between the ship and the ship management company, and data storage disks and the like (servers) are provided at each ship management company. I had to do it myself. The provision of the above-mentioned facilities for each shipping company for a large number of ships of each shipping company that sails the seas of the world does not meet the demand for effective use of software and hardware resources.

Therefore, an object of the present application is to use a communication satellite whose communication speed has recently been increased, collectively manage and manage onboard data at a land-based outsourcing management company, and register each of the registered clients. It is an object of the present invention to provide a ship operation management method and system in which shipping companies can analyze the data via the Internet using the data and perform preventive maintenance of troubles of the main engine and the like.

In order to solve the above-mentioned problems, a ship operation management method according to the present invention provides a ship personal computer with at least data of at least an engine of a ship being operated as ship information. The data is automatically captured and recorded, and the recorded data is entered via a communication satellite into a data server of a system management company installed on the land side and stored. It is characterized in that it is possible to browse various ship information by accessing via a ship.

[0007] Thus, the management of the data server can be transferred to a system management company having knowledge of computers in a lump, so that the client (ship management company) does not need to manage the data server. Data storage and management can be performed by a data server of a system management company installed on the land side with good management conditions. Collective management by the system management company enables high-quality service and quick response to troubles. Further, when searching data on the computer of the data server, the search can be performed via the Internet, and even when a plurality of clients (ship management companies) access the search, only the own ship can be searched using the password. Using the interactive nature of the Internet, operation management, including preventive maintenance of ships, can be facilitated from the land side without leaving it to the ship.

If the ablog data is input as electronic data to the onboard personal computer, it can be browsed from the land side at any time, and the trouble of inputting and correcting the data can be omitted.

[0016] A maintenance management menu capable of importing and processing data from the data server via the Internet is provided on the server personal computer, and a database of the inspection dates and replacement times of parts in the ship is provided, and a replacement time instruction is automatically transmitted to each ship. It is preferable that the on-shore database receives information from the ship on whether or not it is implemented and automatically updates the next schedule. Maintenance onboard can be remotely performed from the land side.

In this case, it is preferable to display spare part data necessary for maintenance of only the maintenance target by designating the maintenance target. As a result, the parts necessary for the inspection of the maintenance object can be immediately identified, so that the inspection operator can take out the spare parts from the ship warehouse and take them to the site in accordance with the parts.

A spare part management menu capable of importing and processing the data of the data server via the Internet is provided on the server personal computer, the number used on the ship side is entered in the spare part stock information, and the spare part information which has become less than the minimum stock number is landed. By contacting the side and automatically creating a purchase request form, it is possible to remotely manage spare parts onboard from the land side.
Spare parts information is managed on the land side, a purchase request form for inventory shortage is automatically issued and linked to maintenance management, and the number of spare parts used in each maintenance can be managed.

If all of the above communications are performed with encrypted data, security can be ensured.

Further, the ship operation management system includes an onboard personal computer that automatically records at least ship information including at least data on engine parts, and a ship information transmitted from the onboard personal computer via a communication satellite. A data server of a system management company that collectively manages and stores the data on the land side, and a client personal computer that can access the data server via the Internet and browse various ship information.
