| This thesis applies Safety System Engineering to the risk assessment of Zhenhai chemical terminal . The Zhenhai chemical terminal has developed for about twenty years , By now, they have built nine chemicals berths and 180 tanks in the harbour area. The total capacity of the whole tank is more than 700,000 stere . A lot of manufactories in Ningbo and Xiaoshan,shaoxin county has choose the Zhenhai chemical terminal as the storage base for producer's goods. Most of the cargoes handled in the zhenhai chemical terminal are the inflammable and explosive chemicals. Serious accident such as fire & explosion and leakage & diffusion of poison cargo would happen there. In order to avoid such serious accident , the administrators should pay great attention to the safety of the harbour .But now there are lack of the systemic assessment to the dange and imperilment of the Zhenhai chemical terminal, In general , The occurrence of fire & explosion and leakage & diffusion of poison cargo accidents in different chemical terminal may due to the similar reason, So the quantitative analysis of the occurrence is not only necessary but also referential . In this thesis, the danger and imperilment of the representative cargo-Acrylonitrile has been analysed in different site ,the condition of tanks , wharfs and also climate in zhenhai chemical terminal are adopted in the assessment. After assessment, the shortage of management can be find, which will make for the safety manager to establish pertinence measures for safety.Although these accidents in chemical terminal can beget and effect each other, they are different in theory, time and area. This thesis choose the representative cargo-Acrylonitrile which is also the focus of safety in Zhenhai chemical terminal. The assessment of occurability of the accident is focused on the nature of the cargo and is assessed through quantitative analysis. The quantitative analysis of the wharf area, tank area and truck loading site are conducted respectively. Here DOW Fire&Explosion index and Integral Rate will be used to assess the danger and imperilment of Zhenhai chemical... |
