A Novel Method for Risk Assessment and Simulation of Collision Avoidance for Vessels based on AIS

open access: yesAlgorithms, 2018
The identification of risks associated with collision for vessels is an important element in maritime safety and management. A vessel collision avoidance system is a topic that has been deeply studied, and it is a specialization in navigation technology.

A Clustering Analysis for Identifying Areas of Collision Risk in Restricted Waters [PDF]

open access: yesTransNav, 2013
The identification of areas of collision risk in restricted waters could play an important role in VTS services. Based on the concept of ship domain, this paper introduces a model for identifying collision risk between vessels in restricted waters, then ...

Interval Type-2 Fuzzy Inference System Based on Closest Point of Approach for Collision Avoidance between Ships

open access: yesApplied Sciences, 2020
According to International Regulations for Preventing Collision at Sea, collision avoidance started from assessing the collision risk. In particular, the radar was mentioned as suitable equipment for observation and analysis of the collision risk.

Risk of collisions for constellation satellites [PDF]

open access: yesNature, 1999
The increasing quantity of debris orbiting the Earth is causing concern for space agencies. At the average collision velocity of 10 km s-1, even projectiles 1 cm across can damage satellites. Impacts have a significant chance of occurring, especially for large structures that remain in orbit for a long time 1.

Over a decade of failure to implement UNEP/EUROBATS guidelines in wind energy planning: A call for action

open access: yesConservation Science and Practice, 2022
Wind power generation has grown exponentially over the past 20 years to meet international goals of increasing the share of renewables in energy production. Yet, this process has too often been conducted at the cost of airborne biodiversity such as birds

Assessment Method Based on AIS Data Combining the Velocity Obstacle Method and Pareto Selection for the Collision Risk of Inland Ships

open access: yesJournal of Marine Science and Engineering, 2022
A ship collision risk assessment model is an essential part of ship safety navigation. At present, the open water collision risk assessment model (such as the closest point of approach) is applied, but a ship collision risk model suitable for inland ...

Comparing pre- versus postoperational movement of nocturnal migrants around a wind energy facility in northeast British Columbia, Canada

open access: yesAvian Conservation and Ecology, 2017
We used two data-recording, open-array marine surveillance radars to track microscale movements of nocturnal migrants at a wind energy project in northeast British Columbia during the preoperational (2008-2010) and operational periods (2011-2012).

Collision Risk Inference System for Maritime Autonomous Surface Ships Using COLREGs Rules Compliant Collision Avoidance

open access: yesIEEE Access, 2021
Maritime autonomous surface ships (MASS) need to be sufficiently safe to gain commercial acceptance. Collision avoidance strategies in such MASS should comply with the International Regulations for Preventing Collision at the Sea (COLREGs).
