Abstract

Analysis to the systematic safety influence factors of petrochemical dock based on the ism model

Author(s): Ye Jihong, Shi Yimin

Aiming at the correlation relationship among eleven safety factors when petrochemical dock system is established, this paper deeply analyzes the lateral and longitudinal relations between these factors by using the Interpretative Structure Modeling (ISM) method of system engineering. And it also establishes four layers hierarchical explaining a structure model which reveals the influence level and the relationship among various factors on petrochemical dock system security. First, security management, which is the highest level of these effect factors in petrochemical dock system. The second level includes the technology and equipment of dock handling, the rear reservoir tank layout, transportation equipments, supply-distribution facilities and public support facilities; all of those belong to the middle level and interconnect with each other. The third level contains the dock building layout and channel water conditions, which belong to the intermediate level and interconnect with each other. The fourth level is the basic level, including meteorological and hydrological conditions, geological conditions and the surrounding buildings, which are the environmental conditions of building petrochemical dock. Distinguishing the functional levels and inter-relations of the main safety influence factors can provide theoretical guides and references for grasping the establishment, planning, design and construction of petrochemical dock system.
