Modelling ship collision risk based on the statistical analysis of historical data: A case study in Hong Kong waters

Ocean Engineering, 2020
Collision, as a common type of ship accidents, leads to serious property loss and personal injury. In this paper, a new framework of quantitative risk assessment is proposed by quantifying the probability and the corresponding consequence based on the ...

Ship collision risk threatens whales across the world's oceans.

Science
After the near-complete cessation of commercial whaling, ship collisions have emerged as a primary threat to large whales, but knowledge of collision risk is lacking across most of the world's oceans.

Potential risk ship domain as a danger criterion for real-time ship collision risk evaluation

Ocean Engineering, 2019
One of the most useful method to indicate the risk of ship collision is the ship domain. After decades of development, different ship domain models have been constructed from various aspects.

An analysis of ship collision risk parameters based on speed ship domain

2021 4th International Symposium on Traffic Transportation and Civil Architecture (ISTTCA), 2021
According to a large number of contemporary studies on ship collision avoidance, the traditional DCPA and TCPA are not enough to estimate the ship collision risk and plan the avoidance operation. In order to solve the problems of insufficient accuracy of

The Risk of a Ship Encounter Leading to a Collision

Journal of Navigation, 1978
An area of sea in which there are several traffic streams may be characterized by the number of potential encounters between two ships that would be expected to take place. The traffic flow in an area of 300 sq. n.m. of the Dover Strait over a nine-year period has been analysed to give the numbers of such potential encounters of head-on, crossing, and ...

Ship Collision Avoidance Timing Based on Subjective Collision Risk

2018 3rd IEEE International Conference on Intelligent Transportation Engineering (ICITE), 2018
In order to reduce ship collision and promote the safety of navigation. We investigate the fuzzy relational between various factors and the timing of collision avoidance of ships combined with the collision risk, and a method for determining the timing of ship collision avoidance is proposed.
