creation of a novel instrument for comparative analysis and objective risk assessment in coastal waters

Abstract

Maritime traffic risk assessment tools, such as the 
Waterway Risk Assessment Program and Ports and 
Waterway Safety Assessment, were established by the 
International Association of Marine Aids to Navigation 
and Lighthouse Authorities (IALA) for use at ports and 
approaches. However, its efficacy has not yet been 
thoroughly confirmed in coastal waters. Statistics show 
that the majority of human-caused incidents happened 
around the shore. It must create a new technology that 
takes human factors into account. The goal of this 
research was to create a new coastal model because of 
this. Data availability in coastal seas was used to identify 
common risk factors for the risk assessment models 
from three maritime states. Risk occurrences were 
determined using quantitative data, and risk weight was 
determined using a qualitative survey for the indexed 
elements. The Numerical Risk Assessment Model for 
Coast (NURI-C), a recently created model, effectively 
identified areas with notable hazards as well as the risk 
level of each target water for comparison. As a result, it 
might be used to determine which coastal areas are more 
hazardous and which risk factors need immediate 
attention. NURI-C may be helpful for both safe 
navigation and the effective allocation of scarce 
resources for coastal safety.
