abstract: Gao, M. 2020. Application analysis of plc technology in automatic control of ship auxiliary machinery.  Bai, X. and Zhou, H. (eds. Advances in Water Resources, Environmental Protection, and Sustainable Development.  In the process of ships sailing on the sea, auxiliary machinery and equipment play an indispensable role, which not only can provide necessary services for ships, but also can ensure the normal navigation of ships. As an advanced technology, PLC technology of mechanical automation control has obvious characteristics, flexible and convenient operation and wide functions. The application of PLC technology in the automatic control system of ship auxiliary machinery is studied and analyzed to provide more favorable support for stable navigation of ships. In the application process of PLC ship auxiliary machinery control system, incomplete information, insufficient data and other uncertain factors will also have a great impact on the system, which will threaten the reliability of the system. Therefore, it is of great significance and far reaching influence to strengthen the application of PLC technology in automatic control devices of ship auxiliary machinery.

title: Research on control system of intelligent shore to ship power connecting pile based on PLC technology
abstract: In order to alleviate the environmental pollution in the port, more and more ports have begun to supply power to various ships moored at the port. Ships can be connected to the shore to ship power source to get the power instead of fuel electricity generation. Thus, the air pollution, water pollution and noise caused by the generation of electricity can be avoided. However, at present, most shore to ship power supply equipment has the disadvantages of simple equipment, low intelligence and low safety. In order to overcome the disadvantages of traditional power connecting pile, a new control system is proposed in this paper. The high performance SIEMENS PLC is applied as the main controller in the power connecting pile. It can provide convenient power supply service for the mooring ships through the operation mode combining the touch screen with the physical buttons. The power connecting pile has the functions of identity identification, power supply guidance, electricity charge, temperature and humidity control, and fault diagnosis. The new system will increase the intelligence and safety of the power connecting piles.

title: Design of a Shipboard Outside Communication Network and Its Testbed Using PLC: For Safety Management during the Ship Building Process
abstract: For the shipbuilding industry worldwide, work related accidents at the construction site have been a major concern. Workers at the shipyards are consistently exposed to dangerous environments and their intensity of work is quite high. Considering the complexity of the shipbuilding process, efficient communications between workers are essential in the workplace, but current communication methods, which mostly use wireless technologies, are sometimes limited by the structural blocks, creating shadow areas where the radio bands cannot reach. As a countermeasure, SUNCOM Co. Ltd in the Republic of Korea has developed the PLC based communication system followed by establishing a test bed facility in cooperation with SK Telecom Co. Ltd and the Hyundai Heavy Industries Co. Ltd. This system and applied technologies are expected to reduce accidents in the field and be applied for other industries having the same problem, providing an uninterrupted communication environment and safer working conditions. The solution adopted this time can provide mobile communication services inside the ship during shipbuilding, thereby enabling rapid processing of work reports and instructions and fast responses to disaster occurrence, contributing to improvements in work efficiency in shipbuilding yards and ensuring workers' safety.

title: Design of Temperature Control System of HFO Fuel Type on Ship Based PLC
abstract: Fuel is one of the important component of ship operations. The overall operating cost of the vessel, approximately 60% consists of fuel costs. The unavailability of fuel causes the ship's operational processes to be adversely affect the company from both technical and material terms. It is a bad condition if ship's fuel does fulfilled the time schedule. To reach the fuel operation criteria and help ships crew operate the fule system, we propose the method to control fuel system. Our objection is how to make ship fuel system can be operated automatically as well as temperature control system on the vessel using PLC. This automation system relies on high level sensors and low level sensors as well as temperature sensors in each tank to trigger the performance of each of the fuel system support equipment such as pumps, valves, heaters. The sensor and thermometer in the tank will be processed by the PLC prior to controlling the equipment. Processing is sequentially adjusted to the processing sequence of HFO fuel. Processing is done based on existing ship data but still using the control manually. As well as recommendations from the classification bureau and machine manufacturers. The work process of the system can be monitored as a whole through Human Machine Interface. The monitor consists of a view that contains all the work of the existing system. The PLC used is OMRON CPM2A with CX Programmer software and CX Designer monitor. So by simply using a control device in the form of PLC, HFO processing can be operated automatically both when the ship is idle or in sail condition

title: Design of a Shipboard Outside Communication Network and the Test Bed Using PLC: for the Workers' Safety Management During Ship Building process
abstract: Industrial disaster involving the workers at the shipyard is one of the major problems of the shipyards all around the world. The workers are usually exposed to the dangers and their works are very tough. The lack of efficient communication methods which enable smooth communications despite of communication shadow areas makes it harder for them to adapt to the working environment. To deal with such situation, SUNCOM Co. in the Republic of Korea developed and designed a PLC based communication system and conducted Test Bed experiment together with SK Telecom, (a national telecommunication company) and Hyundai Heavy Industries Co. Ltd. (a national ship building company) The developed technology is expected to play an efficient and effective role at the shipyards and will be applicable to other industries, helping the workers with uninterrupted communications to improve their working environments.
