Portfolio of port-centric supply chain disruption threats

Purpose -The purpose of this paper is to provide a risk assessment of port-centric threats that may have adverse effects on supply chain continuity from the perspectives of port operators and port users, thereby determining the significance of these threats to supply chain disruptions. Design/methodology/approach - Drawing on literature review and reported cases, 19 port-centric disruptive events were identified. Subsequently, surveys were conducted to collect data from 102 port operators and 123 port users worldwide on the frequencies and consequences of the identified port-centric disruptive events. Risk matrices were then generated to compare the perspectives of port operators and port users. Findings -The results show that threats related to the planning of port resources require the highest level of attention. This highlights important areas for port managers seeking to improve port resilience and supply chain continuity through a more prudent management of risks. Research limitations/implications -The results help port managers understand where they should establish strategic capability to increase port resilience and enhance sustainability to benefit port users. However, the study could be further enhanced by evaluating the threats based on different regions of ports and port users and making recommendations for port operators to undertake. Originality/value -The findings of this paper are significant as they provide an analysis of data gathered from international port operators and port users. Risk matrices have been widely applied in many industries, yet no studies have been conducted to develop a portfolio of port-centric risks at a scale as large as this paper.
