Abstract

Oil storage tank is an important facility for oil production and refining. This paper presents a fire monitoring system for oil storage tank based on distributed optical fiber temperature sensing system(DTS), and demonstrates the laying method for both routing fiber and temperature sensing fiber. This system can realize real-time distributed temperature monitoring on the perimeter of secondary sealing ring of oil storage tank and has various alarm mechanisms. The system has been installed and tested in Shikong oil transportation station of China National Petroleum Corporation(CNPC) in Gansu, China. Through the actual test results, the feasibility and advantages of the distributed optical fiber temperature measurement for oil storage tank are verified and the temperature accuracy of the system is better than 1°C.
