Safety Assessment Model for Coastal Passenger Vessel in the Perspective of Compatibility of Life Jacket with the Coastal Passenger Vessel

This paper proposed a new model referred as Life Jacket Compatibility Index Static Model (LCI). The reason for the development of this model was due to accidents associated with the usage of life jackets on board the passenger vessels. This new model was developed based on the combination of variables of models of life jacket and passenger vessel. These models were combined by compatibility, which is a new variable introduced in the study. The algorithm of the model is developed based on Fault Tree Analysis and Boolean Logic Gate. The purpose of the model is to rate the safety of coastal passenger vessels in the perspective of compatibility of life jackets with the coastal passenger vessel, which is a new perspective on safety assessment of passenger vessels. Another purpose of the model is to determine the maximum capacity of passenger based on available area to don the life jackets, which is also a new perspective to determine the maximum capacity of passengers. The model can be used by the maritime authority to regulate the safety operation of the coastal passenger vessels. The introduction of LCI model contributes to a new method of assessment of passenger vessels in the field of maritime safety.
