The EC funded CyClaDes research project is designed to promote the increased impact of the human element in shipping across the design and operational lifecycle of ships. It addresses the design and operation of ships and ship systems. One of the CyClaDes’ tasks is to create a crew‐centered design case‐study examination of the information that is shared between the Bridge and Engine Control Room (ECR) that helps the crew coordinate to ensure understanding and complete interconnected tasks. This information can be provided in various ways, including communication devices or obtained from a common database, display, or even the ship environment …

The maritime industry is still characterized by prescriptive standards and reactive approaches in relation to safety and risk management to a large extent. For a very long time, responses to maritime accidents have been in terms of automation, regulation and training. While this as such is not wrong, it does not offer the full potential that concepts of resilience seem to suggest. The typical question that is predominately asked is still why things go wrong when accidents occur and search for causes and explanations is undertaken. An evaluation of the safety level achieved system and a focus on system components …

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

In the past two decades, the need to address human factors in shipping through integration of ergonomics in the design of ships and shipboard equipment has increased significantly as a result of the technological development of modern ships. The International Maritime Organization (IMO), the United Nations’ specialized organizationfor ship safety issues, has adopted a vision to address human factors as a key element for the improvement of maritime safety, and in that context acknowledges the human element as complex and multi-dimensional. IMO’s standards focus on the avoidance of human and organization error. But in spite of this, and despite the …

Control And Resilience Within The Maritime Traffic Management Domain, Gesa Praetorius
Control And Resilience Within The Maritime Traffic Management Domain, Gesa Praetorius
Gesa Praetorius
This article presents research conducted within the Vessel Traffic Service (VTS) domain. VTS is a service that is provided close to ports and geographically challenging areas to support merchant vessels in their navigation. Although VTS is legally an advice and assistance service, applying concepts from Cognitive Systems Engineering and Resilience Engineering can highlight how the joint human-machine system works to promote safe and efficient traffic movements. The VTS is a Joint Cognitive System that maintains control through a mixture of opportunistic and tactical control. Strategic control is only partially supported by the higher levels of system aggregation that provide the …
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
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 …
Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius
Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius
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 centralised …

“Under Dangerous Conditions” – Safety Construction And Safety-Related Work Onboard Of Merchant Vessels, Gesa Praetorius, Monica Lundh
Gesa Praetorius
The following paper presents findings from a qualitative study conducted on board of two merchant vessels. Interviews and observations have been used to obtain insights in how safety is defined and promoted by the personnel working on board. The merchant vessel, the crew and the single mariner are identified to be part of a socio-technical system displaying three levels of system aggregation; person-centred, crew-centred, and vessel-centred. The common ground of a crew, an overlap of the individual mariners’ experience and knowledge, is identified as a basis for trust and predictability of action on board, which is a necessity to be …
Decision Support For Vessel Traffic Service (Vts): User Needs For Dynamic Risk Management In The Vts, Gesa Praetorius
Decision Support For Vessel Traffic Service (Vts): User Needs For Dynamic Risk Management In The Vts, Gesa Praetorius
Gesa Praetorius
Vessel Traffic Service (VTS) is a shore-side service implemented by a “Competent Authority to improve the safety and efficiency of vessel traffic and to protect the environment”. It is a service that operates through VTS centers, from which VTS operators monitor traffic, assist in navigational matters and provide information to all ships in a designated area. As VTS is provided by operators located on shore, they usually make use of several decision support systems to be able to monitor the traffic and to provide information to the vessels. Although several new tools and approaches have been introduced in the VTS …

Safety Within The Vessel Traffic Service (Vts) Domain. Understanding The Role Of The Vts For Safety Within Maritime Traffic Management, Gesa Praetorius
Gesa Praetorius
Vessel Traffic Service (VTS) is a shore-sided service implemented to promote the safety of navigation, safety of life at sea, and the protection of the marine environment. Its purpose is to work for safe and fluent traffic movements within a determined area, a VTS area. VTS is provided by VTS operators, skilled experts that provide vessels with information and advice, and work for the overall traffic organisation. Although VTS is regulated on an international level there are differences in how the service is provided in between countries, and even VTS centres. This licentiate thesis focuses on understanding the role of …
Safety Is Everywhere-The Constituents Of Maritime Safety, Gesa Praetorius, Margareta Lützhöft
Safety Is Everywhere-The Constituents Of Maritime Safety, Gesa Praetorius, Margareta Lützhöft
Gesa Praetorius
Although maritime safety is one of the key terms in regulation, guidelines and recommendations, such as SOLAS (International Convention for the safety of life at sea (IMO, 1974), in the shipping domain, there is, to the best of our knowledge, neither an explanation of this specific type of safety nor any explicit understanding on how it is promoted by those who work on board of merchant vessel. This qualitative study approaches maritime safety from a crew perspective and discusses what constituents should be considered to be part of maritime safety.

Vessel Traffic Service (VTS) is a service to the maritime community implemented to promote and improve maritime safety. In recent years VTS has become a topic of increased interest for maritime stakeholders and the general public. To derive insights on how maritime safety is constructed in the VTS domain this exploratory study was conducted. Four VTS centres were visited and 15 VTS operators were interviewed and observed at work. Further a focus group interview with 8 VTS operators with focus on decision support tools in the VTS domain was conducted. The results of the study indicate that VTS operators define …

Enacting Reliability: First Steps To Define Safety In The Vts Domain, Gesa Praetorius, Karl Bruno, Margareta Lützhöft
Gesa Praetorius
Although the term maritime safety is widely used in the maritime industry, there is no exact definition of what it entails. An explorative study of the VTS domain has been conducted to approach the concept of maritime safety. Four VTS centres were visited and 16 VTS operators were interviewed and observed to derive insights in how maritime safety is constructed from the perspective of an operator. Further, definitions of maritime safety by central actors in the maritime domain have been investigated through a literature study and several interviews. The results indicate that there is no common definition of the term …
