A Hybrid A*‐APF Path Planning Method for Ships Entering the Berthing Waters

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper presents a two‐stage hybrid path planning approach for ship berthing: the first stage builds an accurate environmental model based on berth features and the second stage combines an improved A* algorithm (with directional consistency penalty) and the artificial potential field method to generate feasible paths and enhance local obstacle ...

Study on ship automatic berthing system with mooring lines

China Ocean Engineering, 2017
This study describes an automatic berthing system with mooring lines. It is designed to be berthed by using mooring device on the upper deck of a ship. It is to berth once maintaining parallel with the quay by controlling both forward and aft breast lines.

Graph Neural Network‐Enabled Robust AIS/Radar Data Association for Intelligent Monitoring of Ship Safety

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
We propose a graph neural network (GNN)‐enabled robust AIS/radar data association method to address limitations of existing methods, that is, time asynchrony, spatial differences, and environmental noises. Our novel computational method performs well in efficiency and accuracy, and promotes the safety monitoring capabilities of ships in the shipping ...

Managing Import Dependency Risks in Contexts of Polycrises: The Case of Jordan

Global Policy, Volume 16, Issue 5, Page 1111-1124, November 2025.
ABSTRACT This study examines the critical role of trade facilitation in enhancing food security in Jordan, a country where 90% of essential food items are imported. Despite being a regional leader in implementing the WTO Trade Facilitation Agreement (TFA), Jordan faces persistent challenges due to logistical inefficiencies, institutional fragmentation,

The essential role of large research vessels in marine ecosystem observations and ocean sustainability

Limnology and Oceanography, Volume 70, Issue 9, Page 2767-2792, September 2025.
Abstract Our understanding of marine ecosystems and ability to manage them sustainably has come from multidisciplinary observations made repeatedly over long periods of time. These long‐term ecosystem observations depend on the capabilities of large research vessels, which play an essential role in the collection of global ocean observations.
