a) Tanjong Pelepas Port plant is divided into three systems as shown in Fig.1. This corresponds to the three activities of the companies: unloading, storage, and loading for distribution. There are three levels for each activity - system level, sub-system and nodes. These three systems are divided into six sub-systems and these again are divided into specific points or nodes that correspond to the sequence of operational steps in the plant as demonstrated in Table 1. In addition, Appendix 1 shows the guide words and parameters used in the HAZOP analysis.

Question

The faults and relationships for each top event have been identified and a logical combination of incidents has been deduced that can trigger unwanted events. In this way, each tree contains information about how the combination of certain faults leads to overall failure.
As an engineer, you were given the task to construct a maximum three layers of any
TOP THREE FTA EVENT from above contributors.
