Intelligent Ship Collision Avoidance Algorithm Based on DDQN with Prioritized Experience Replay under COLREGs

open access: yesJournal of Marine Science and Engineering, 2022
Ship collisions often result in huge losses of life, cargo and ships, as well as serious pollution of the water environment. Meanwhile, it is estimated that between 75% and 86% of maritime accidents are related to human factors.

A Simple Problem of Ship Collision Avoidance

open access: yes, 2023
There are various advanced algorithms developed to search for optimal solutions, i.e. optimal navigation trajectories, have been utilized for collision avoidance among ocean-going vessels by the research community. It is noted that such optimization solutions may not be a mandatory requirement in realistic ship encounter situations, due to the main ...

ASPECTS OF DIGITALIZATION OF SHIP COLLISION AVOIDANCE REGULATIONS

open access: yesShipping & Navigation, 2023
The study is devoted to the development of proposals that would allow for a more complete consideration of the requirements for actions to avoid ships in various situations. On the basis of the analysis of methods for ensuring safe avoidance it is established that the most suitable variant of setting safety limits can be considered as target domains ...

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Optimal Collision-Avoidance Manoeuvres to Minimise Bunker Consumption under the Two-Ship Crossing Situation

open access: yes, 2017
This paper optimises two-ship collision-avoidance manoeuvres accounting for both collision risk and fuel use. A collision-avoidance manoeuvring optimisation model is developed to minimise fuel consumption while assuring ships' operational safety.

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.
