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.

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.
Develop the HAZOP analysis for node 2.1.1 (opening tank valves) and node 2.1.2 (filling
tank) of the given system.
