Navigating Arctic Waters: A Summary of Ship Activities and Ice-Ship Interactions in Alaskan Waters

Climate change is affecting global weather patterns, but nowhere is this more apparent than in the Arctic. The Arctic is an extreme environment going through rapid climate change, resulting in the opening of new shipping lanes and leading to less multiyear ice formation. This increases the risk of collision with the sea ice making it difficult...

Real-time collision risk based safety management for vessel traffic in busy ports and waterways

Regional risk analysis and management of maritime accidents is one of the fundamental tasks for maritime safety management. With the heavy and complicated maritime traffic in the ports and waterways, accidents, especially ship collision accidents, have been continuously posing threats to the maritime transportation system. To achieve effective...

Probabilistic Risk Analysis for Ship Collision-Theory and Application for Conventional and Autonomous Ships

Maritime transportation has been one of the major contributors to the global trade and economy. Accidents, however, have been continuously posing risks to individuals and societies in terms of loss of human life, economic and environmental consequences, etc. This thesis paid particular attention to the probabilistic risk analysis of ship...

Archiving AIS messages in a Geo-DBMS

This paper reports on the result of two studies for using a geographical database management system for archiving Automated Identification System (AIS) message data. In this paper, we analyse the storage (using MongoDB and PostgreSQL) and we give a more in-depth description of a possible data model for archiving messages based on the bit vector...

Vessel classification method based on vessel behavior in the port of Rotterdam

AIS (Automatic Identification System) data have proven to be a valuable source to investigate vessel behavior. The analysis of AIS data provides a possibility to recognize vessel behavior patterns in a waterway area. Furthermore, AIS data can be used to classify vessel behavior into several categories. The analysis results would help the port...

AIS data anlaysis for realistic ship traffic simulations model

AIS (Automatic Identification System) data provide valuable input data for the development of simulation models to prevent shipping accidents. This paper reports on the detailed analysis of AIS data for that purpose. This analysis is focused on restricted waterways to support inland waterway simulations, comparing the differences between a...

Artificial Force Fields for Multi-agent Simulations of Maritime Traffic: A Case Study of Chinese Waterway

Collisions are an important factor in probabilistic risk modeling of waterway infrastructures. Especially in the design of bridges and terminals, the probability of ship collision is important. Researchers are looking for simulations that mimic ship behavior and estimate accident probabilities rather than using probabilistic accident models. AIS...

AIS data based vessel speed, course and path analysis in the Botlek area in the Port of Rotterdam

Maritime traffic safety and port capacity is increasingly important nowadays. Due to the fast development of vessel traffic in ports and waterways, a lot of attention has been paid to maritime traffic safety and port capacity. Many simulation models have been used to predict traffic safety and port capacity m ports and waterways. However,...
