Abstract

Conventional buoy mooring (CBM) is one of the common cargo discharging/loading operation for tankers and allows handling of liquid cargo such as petroleum products for big size tanker ships. The nature of operation is quite difficult and requires utmost care. Therefore, the ship crew must be fully aware of hazards and potential failures. The expectation from ship crew is to complete required tasks without any failure. In this context, the aim of this paper is to predict human-based error probabilities (HEP) systematically under interval type-2 fuzzy sets (IT2Fs) extended human error assessment and reduction technique (HEART) approach. Since the HEART is systematically calculating HEP for each specific task in the system, the IT2FSs tackle with uncertainty and vagueness of judgements in decision-making. Besides practical contributions in safety and reliability assessment in CBM operation for tanker ships owners, safety inspectors and HSEQ managers, the paper has theoretical insights. In conclusion, the outcomes of the paper are to contribute monitoring the performance of ship crew as well as safe operation of CBM off-shore units in maritime transportation.
