Introducing The Concept Of Resilience Into Maritime Safety, Jens-Uwe Schröder-Hinrichs Phd, Gesa Praetorius, Armando Graziano, Aditi Kataria, Michael Baldauf

Gesa Praetorius

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 …

Increased Awareness For Maritime Human Factors Through E-Learning In Crew-Centered Design, Gesa Praetorius, Aditi Kataria, Erik Styhr Petersen, Jens-Uwe Schröder-Hinrichs, Michael Baldauf, Nina Kähler

Gesa Praetorius

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 …

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 …

“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 …

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

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.

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 …
