The present study is a continuation of our first work, which was conducted in Algerian ports, the objective of which was the management of risks related to port maneuver in Algeria. This study aims to achieve a better understanding of stakeholder's perception in the matter of port maneuver regarding the origin of risk and its consequences. This perception may be either objective or subjective. What is important is that this study reflects a reality that can enlighten experts and decision makers, thus allowing them to make specific decisions. Seventy-two stakeholders in maneuver from ten different Algerian ports have responded to our questionnaire on risk perception. The results confirmed that different parameters are at the origin of this perception.
