Abstract. In recent years, the HAZOP analysis method has been widely used in
the process safety analysis and evaluation of long-distance oil and gas pipeline
stations. However because it cannot give quantitative assessment, whether the
risk can be controlled within acceptable range by safety measures can hardly
be judged. To compensate for these deficiencies, LOPA analysis was introduced
on the basis of HAZOP analysis. By studying the characteristics of HAZOP and
LOPA analysis methods and the relationship between them, it is found that the two
can be complementary and combine to enhance the safety analysis effect. Taking
a pipeline station of refined oil for example, the assessment effect of the proposed
HAZOP-LOPA risk assessment method is discussed. The results show that the
HAZOP-LOPA method can not only quantify the risk, but also determine whether
the existing safety measures are sufficient or not. The HAZOP-LOPA method can
effectively overcome the shortcoming of HAZOP analysis method and improve
the accuracy of risk assessment.

1 Introduction
As a key part to ensure the normal operation of the entire oil transportation system, the
station plays a role of regulation and control in the oil transportation process. The station
is composed of numerous facilities, operating in a complex mode which is controlled
by a complicated controlling system. Once there is any accident in the station, serious
consequences such as fire, explosion and environmental pollution may be caused. Therefore, it is of great significance to carry out functional safety assessment for station to
find out and control the possible risks in its production and operation.
2 Overview of Analysis Methods
2.1 HAZOP
HAZOP (Hazard and Operability) analysis is a method of security analysis proposed by
Imperial Chemical Industries (ICI) in the 1960s. After more than 50 years of improvement, it has been widely applied in engineering projects in China and abroad, becoming
a common hazard and risk analysis method [1].
