The System Dynamics in the Human Reliability Analysis Through Cognitive Reliability and Error Analysis Method: a Case Study of an LPG Company

Abstract

The storage and handling procedures of Liquefied Petroleum Gas (LPG) institutes a multifaceted operational situation in the maritime means of transportation. The LPG cargo is supported by a mainly designed ship and registered LPG companies. The LPG cargo loading and discharging manoeuvers always have possible vulnerabilities. Thus, the crew on-board LPG companies should be completely alert of operational hazards throughout the cargo handling procedures, including numerous grave tasks such as drying, inserting, gassing-up, cooling, and re-liquefication. During these phases, human consistency plays a vital role in the maintainable conveyance of cargo. Human Reliability Analysis (HRA) has always been a grave factor for safety engineers and risk assessment experts. HRA is linked to numerous strictures such as the human factor, expertise, and ergonomics, which is still a grave deliberation when concerns with maritime safety and the environment. In this case study, the focus is placed on an LPG storage facility through the Cognitive Reliability and Error Analysis Method (CREAM) methodology, which is selected among the most known and used methods for HRA. In the end, it is proved that investing in safety is crucial, and Human plays an important role.
