e-Navigation requires shipboard integrated information system to manage several kinds of data on shipboard. IEC 61162-450 may be adopted for the development of such system. Based on IEC 61162-450, this paper proposes an architecture of shipboard integrated information system, and describes a developed system. The system is composed of NMEA 2000 gateway, wireless sensor gateway, database, monitoring applications. This paper also shows the feasibility of the system through some tests.

Unlike general ships, offshore plants require high reliability due to their long operating time at fixed positions when they are operated. Sensor-based status information is required for user and maintenance worker to ensure safety. In this paper, we propose a monitoring system for safety diagnosis and inspection of cargo lift for offshore plant. It consists of a sensor unit mounted on the cargo Lift, an embedded system measurement unit, and a monitoring unit for real-time data verification. It is based on the ship standard network IEC 61162-450 for the exchange of operating information and sensor measurement information in accordance with the upgrading and integration of equipment in maritime.

In the reality that the fishing population is decreasing and the single-man fishing vessels is increasing, mandatory equipment for navigation and radio equipments for the safety of fishing boats has continued to be added. Therefore, many equipment such as navigation, communication and fishing are installed in the narrow steering room, so it is very confusing and a number of monitors are placed in the front, which is a factor that degrades the function of maritime observation. To solve this problem, we studied an interface that integrates and operates to major radio facilities such as very high frequency-digital selective calling equipment (VHF-DSC), automatic identification system (AIS) and fishing boat location transmission device (V-pass) into one multi function display (MFD) based on LAN. In addition, IEC61162-450 UDP packets and IEC61162 sentence were applied to exchange data through link between MFD and radio equipments, and additional messages needed for each equipment and function were defined. The integrated MFD monitor is easily operated by the menu method, and the performance of the interface was evaluated by checking the distress and emergency communication functions related to maritime safety and the message transmission status by equipment.

Recently, the on-board equipments of vessels are getting diversifications with high technologies. With changing the trends, the shipboard network is turning to the light-weight ethernet architecture for integrated data management. For that necessity, this paper covers a development of the gateway system which gathers and processes the measured analog or NMEA data from loaded equipments to convert the messages based on IEC 61162-450 (standard for light-weight ethernet network of ships) in engine parts of small vessel. To do this, we analyzed the requirements for standardization of ship's equipments and related studies. To solve the problems of existing equipments, we defined the additional data formats (sentence formatter), developed the gateway system, and verified the utility of the developed system. Consequently, we established an interfacing framework for management and application of the generated data based on the ethernet in vessel.

This paper describes a design and implementation of monitoring applications on shipboard integration network. A wrapping module is designed to reuse pre-developed communication library of shipboard integration network. By using the wrapping module, monitoring applications are also designed to display several kinds of shipboard data. They are implemented and tested on general PC and embedded PC to verify that they can be applicable to different platforms.

In this paper, we analyze and design requirements of Network Function block and System Function block of MiTS network protocol based on Light-Weight Ethernet, also implement and test the protocol and library files. Light-Weight Ethernet Protocol consists of Network Function block and System Function block. NF receives and sends datagram based on UDP multi-casting communication. SF processes messages after distinguished Sentence and Binary Image Data.

Several data from equipments on shipboard have been used for the safe navigation of ships. Due to the varieties of data, however, there may be difficulties to manage those data separately. Therefore, it can be effective to develop database for the integrated management of ship data. However, the database may become full soon because huge amount of data are saved continuously. To cope with this problem, this paper proposes multistage database which can always keep the database under full by means of sampling mechanism. To verify the functionality of the methodology, a prototype system has been implemented and tested.
