FROM SAFETY EVENT REPORTING TOWARDS IMPACT ON DESIGN: HUMAN RISK-INFORMED DESIGN (HURID)

摘要

Nowadays, the maritime world is still strongly linked to traditional and widely adopted rules (regarding systems design, usability, maintainability, habitability, etc.), most of which are standardised in existing regulations. Even if this situation makes it easier to develop, integrate and operate a system in a new ship, it may lead the designer to overlook the role of Human Factors (HF), which should be taken into consideration at a much deeper level. More specifically, ships' systems are normally designed for a nominal condition where redundancy allows a certain degree of degraded performance, in which case the system's residual operability still allows it to conduct navigation at a satisfactory safety level (e.g., 'Safe Return to Port'). This principle is correct, but mainly focuses on system operability and expected operator actions, while little attention is given to the degraded performance of humans, and consequences of factors such as sleep deprivation, fatigue, unreliable communication, and excessive workload among others. All these factors could further degrade ship operability and should play a role in overall risk assessment.
