A real-time ship encounter collision risk detection approach in close-quarters situation

open access: yesMeasurement + Control, 2023
In order to identify ship collision risk for the security of maritime transportation in a close-quarters situation, a novel real-time ship collision risk awareness approach is proposed by developing a novel non-linear velocity obstacle set, QSD-NLVO ...

A Dynamic Business Modeling Approach to Port Sustainability: The Western Sicily Port Authority Case

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Ports are critical nodes in global trade and economic development, yet they generate substantial environmental and social externalities—including greenhouse gas emissions, air, noise, and water pollution, and adverse impacts on host communities—that demand integrated and forward‐looking governance.

A Study on the Design of Coastal Fairway Width Based on a Risk Assessment Model in Korean Waterways

open access: yesApplied Sciences, 2022
In this study, the appropriate fairway width was designed through the maritime traffic safety evaluation model. By applying the concept of L-converted traffic, it was found that the current maritime traffic volume is 5 to 20 ships per hour in the sea ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Preliminary design of a traffic separation scheme at the hub port of IKN: hydro-oceanographic analysis for navigational safety in the Makassar Strait

open access: yesArchives of Transport
The increasing maritime traffic density in the Makassar Strait, particularly due to the development of the Hub Port at Indonesia’s new capital (IKN), necessitates a structured Traffic Separation Scheme (TSS) to ensure navigational safety.

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

open access: yesEcography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...
