Abstract

Autonomous vessels are becoming a hot topic in the global shipping industry. In the EU, Autonomous ship technology is rapidly developing. Autonomous vessels are expected to become a new paradigm to change and accelerate the digitization, platform connectivity and intelligence of the shipping industry. Over the past few years, the marine industry has maintained its competitive edge by securing operating competitiveness by reducing operating costs such as vessel size and oil costs. However, as with other industries, ICBM (Industry 4.0) IOT, Cloud, Big Data, Mobile), cyber security, simulation, etc., and to create new business by maximizing the unique capabilities of the shipping industry as defined in Shipping 4.0. Until recently, autonomous vessels were named as various types such as Smart Ship, Digital Ship, Connected Ship, Remote Ship, Unmanned Ship and Autonomous Ship. They were defined as MASS (Maritime Autonomous Surface Ship) by International Maritime Organization (IMO) This is a comprehensive product and service for the unmanned ship, autonomous transportation and efficient transportation in the stepwise upgrade for safety, reliability, and efficiency in ship operation.

In this paper, the research background and research scope is described in chapter 1, discussion about autonomous ship related contents are in chapter 2. The design and implementation of a large scale ship data transmission system including method of ship communication, data protocol and messaging processing technology to transmit and display large amount of data are describe in Section 3. The configuration and results of the experimental environment are in Section 4. Then finally the conclusion and further studies are described.

Chapter 2 - Autonomous vessels are that incorporate ship control systems and communication technologies that enable wireless monitoring and control, including improved decision support systems and remote control and autonomous navigation capabilities. The control function for the autonomous vessels is implemented in the Shore Control Center (SCC). In order to accurately recognize the situation of the ship at the remote land control center, the existing systems such as AIS and RADAR are equipped with thermal cameras, LIDAR an advanced sensor module is added to the vessel to replace the existing sailing company's watch keeping operations with the landlord and system. The land control center simultaneously monitors the safe operation of autonomous vessels, manages the voyage plan update and autonomous navigation system, and manages the maintenance plan for autonomous vessels.

Chapter 3 - In this paper, we constructed and implemented a large capacity ship data acquisition and transmission system that can collect, process, and transmit data generated from ships. The required physical configuration is largely divided into onboard and onshore, and by design, it can have n ships and n land. On the ship side, data are collected from navigation equipment and AMS (Alarm Monitoring System) such as RADAR, Speed Log, Doppler, Gyro Compass and GPS, processed and stored for use on land and onboard service applications, The land consists of a server composed of modules capable of receiving data from various ships and transmitting them to a required place after processing, and servers for service application. The user is connected to the web browser on the PC and configured to use services such as flight information monitoring.

Chapter 4 - Experiments were conducted on the large scale ship data acquisition and transmission system implemented in this paper by constructing an environment in the T/V Hanbada Lab. For each unit function, the experiment proceeded while the Kongsberg simulator and the training line were at anchor, and the integrated test for the stability and function of the data was conducted during the long voyage.

Chapter 5 - In this study, the research was carried out in order to process the ship’s navigation data generated from various equipment for several number of vessels in terms of ship operation data and remote control center technology for this purpose. For the research on application system implementation and verify evaluation, an analysis of a data collection and process on ship and shoreside and design of data transmission has been studied. Also for this research, the basic research knowledge were achieved together with research results on ship data processing and transmission. The newly developed web based system can used to monitor ship’s data in real-time on the shoreside.
