This paper presents new IT model, PIIS that integrates the safety control, construction, and operation managements in a conventional gas industry The systemic approach based on the PIIS model may reduce or increase the parameters as maximizing the safety, risk and crisis management, and increasing the cost-effective productivity The rapid synchronization and integration of the process using the PIIS model may produce more profits and satisfactions between customer and gas supplier. Thus, the PIIS model should quickly be introduced to gas industry at the beginning stage of engineering design and construction processes for maximizing production, effectiveness, and safety of the system from the exploration of a natural gas to a final consumption.

This paper presents integrated control and safety management system for a LNG storage tank. This system is for collecting and analyzing the temperature, pressure, and vibration signals in which are used to control and guarantee the system safety and leakage control from the inner gas tank. Based on the investigations of LNG tank related failures and accidents, we strongly recommend the modification and new development of current safety related measuring and control systems because the LNG tank is constructed bigger and bigger in recent years for the efficiency and safety increments. Thus, this paper presents newly developed integrated control and safety management system for a large LNG storage tank. This system provides the enhanced measuring and control systems, and new displacement based safety system, which may detect and control the deformation properties of tank structures. In addition, we recommend that the new integrated control and safety management system should be coupled by process integrated innovation system (PIIS) for an increased safety, efficiency, and productivity of LNG tanks.
