Modelling Vessel Traffic Service To Understand Resilience In Everyday Operations, Gesa Praetorius, Erik Hollnagel, Joakim Dahlman

Vessel Traffic Service (VTS) is a service to promote traffic fluency and safety in the entrance to ports. This article׳s purpose has been to explore everyday operations of the VTS system to gain insights in how it contributes to safe and efficient traffic movements. Interviews, focus groups and an observation have been conducted to collect data about everyday operations, as well as to grasp how the VTS system adapts to changing operational conditions. The results show that work within the VTS domain is highly complex and that the two systems modelled realise their services vastly differently, which in turn ...

Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius

Traffic management is not formally organised in the maritime domain. Ships are autonomous and find their own way. Traffic is organised through rules, regulations, and “good seamanship”; it is a distributed system. In areas of high traffic-density support is proved by vessel traffic service (VTS) to promote traffic safety and fluency. VTS does not take control. This organisational structure has proven itself in situations with sufficient resources. When resources become insufficient (e.g. not enough sailing space), the traffic needs an organising mechanism. In this article, the authors argue that the most promising way to do this is by organising ...
