Computer monitoring and control system of a local LNG supply station

This paper presents a proposal of computer system to support the work of local LNG supply station. The main advantages of proposed system are to increase safety and reduce the operating costs of the station. On the basis of preliminary analysis the main functional modules of the system have been distinguished. The modules include: vaporization control unit, subsystem for monitoring parameters in the cryogenic tank and installation, central database server, data visualization module, diagnostic subsystem and module for LNG supplies optimization. The system has been used for investigating a real supply station.
