A Multicriteria Outranking Approach for Ship Collision Risk Assessment

Reliability Engineering and System Safety, 2021
Abstract The paper presents a judgmental expert-based process to assess the ship collision risk using the ELECTRE Tri-nC multiple criteria outranking method. The approach first establishes a set of criteria deemed important by navigation experts, all of them experienced nautical officers, to assess the collision risk between two ships in open waters.

Probabilistic Risk Analysis for Ship-Ship Collision: State-of-the-Art

Safety Science, 2019
Abstract Maritime transportation system has made a significant contribution to the development of the world economy. However, with the growth of quantity, scale, and speed of ships, maritime accidents still pose incrementing risk to individuals and societies in terms of multiple aspects, especially collision accidents between ships.

On the Reliability and Validity of Ship–Ship Collision Risk Analysis in Light of Different Perspectives on Risk

Safety Science, 2014
A number of authors have discussed reliability and validity of quantitative risk analysis (QRA). These concepts address respectively whether a QRA provides the same risk picture when the analysis is repeated and whether the analysis addresses the right concept.

Evaluation of Ship Collision Risk Assessments Using Environmental Stress and Collision Risk Models

Ocean Engineering, 2019
Abstract In Korea, ship collisions represent the majority of marine accidents and are substantially more likely in port areas where ship traffic is dense. To improve the safe navigation of vessels, the Korea Maritime Safety Audit (KMSA) has been conducting maritime traffic flow evaluations based on the Environmental Stress (ES) model since 2009.

Towards Real-Time Ship Collision Risk Analysis: An Improved R-TCR Model Considering Target Ship Motion Uncertainty

open access: yesReliability Engineering and System Safety, 2022
Collision between ships is one of the major contributors to ship accidents. To facilitate the development of the real-time collision risk analysis model for collision avoidance, in this research, an improved Rule-aware Time-varying Collision risk Model ...

Algorithm of the Risk of Ship-Bridge Collision Considering Ship’s Dimension

IABSE Congress Reports, 2022
<p>The issue of ship collision with bridge is very important topic in the academic research, however, the studies only regard the ship as a particle at present, ignoring the size of the ship, which cause the accuracy of the active early warning system cannot meet the requirements of practice.

Collision risk assessment for ships

Journal of Marine Science and Technology, 2010
Efficient maritime navigation through dynamic obstructions at close range is still a serious issue faced by mariners. There have been studies focusing on collision risk assessment in the past, but the majority were based on the first person perspective, with area-based ship domain concepts that are defined around either the ownship or the obstacle ...
