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 affects …


Vessel Traffic Service (Vts): A Maritime Information Service Or Traffic Control System? Understanding Everyday Performance And Resilience In A Socio-Technical System Under Change, Gesa Praetorius Aug 2014

Vessel Traffic Service (Vts): A Maritime Information Service Or Traffic Control System? Understanding Everyday Performance And Resilience In A Socio-Technical System Under Change, Gesa Praetorius

Vessel Traffic Service (VTS) is a shore-side maritime assistance service that supports bridge teams in their safe navigation of port approaches and other areas that present navigational difficulties. The VTS is implemented in national waters and provides vessels with information through transmissions and broadcasts on Very High Frequency (VHF) radio. With a continued growth in the number, size and cargo volumes of merchant vessels, the role of the VTS has recently become a matter of discussion, and it has been argued that changes, such as implementing an aviation-like control system, would be of an enormous benefit for stakeholders and guarantee …
