Content available Identification of errors committed by Vessel Traffic Service operators
Kotkowska Diana, Marcjan Krzysztof

This paper examines the factors affecting the performance of VTS operators. A general review of the human factor as a determinant of navigational safety is presented. The elementary nature of the system and its structure are defined, and the ability of a VTS operator to perform planned tasks within a specified timeframe and in a specific manner is analyzed. A reliability assessment scheme is proposed, which is based on the interpretation of factors affecting the VTS operator’s efficiency. The effective performance of VTS operators, along with the specific nature of the maritime environment and reliability of the vessel traffic management support, are key determinants in the process of ensuring the reliability and security of the entire system.

The vessel traffic system (VTS) operator is an important role in the monitoring and supervision of maritime traffic. The main objectives of the VTS is to improve security in the coastal areas. VTS efficiency depends on the quality of the operators. Certain conditions of work should be provided if the system service is to be reliable as this facilitates proper and effective task performance. This article analyzes the factors affecting the performance quality of VTS operator’s. The aim of this study is to examine the methods that indicate negative factors affecting the efficiency of the VTS operator. The result of the study is primarily a reliability analysis of VTS, which underlines the importance of a thorough understanding of the factors associated with human reliability. These methods are crucial to determining VTS operator errors, and gaining an understanding of the consciousness of the operator’s actions in the workplace. Future negative factors can potentially be eliminated by answering questions about the guiding forces, actions and reactions of the operator to external stimuli in a specified scenario.

Increasing of the navigation safety level, especially in difficult and heavy traffic areas, is the main reason of VTS creation. The Navi-Harbour 5000 is the one of the newest systems created for VTS system management and it fulfils requirements included in IMO Resolution A.857(20). Main system functions of the vessels traffic movement monitoring are characterized in this article. The effectiveness of the VTS operator work should be increased by proper configuration and use these functions in everyday service.

This paper is the report on operational and legal status of the Polish AIS network established by Polish Maritime Administration. Existing structure of base stations, telecommunication network as well as current radio coverage within a Helsinki Commission (HELCOM) area is described [2]. Authors present the current status and practical operational applications of the AIS-PL to control a marine traffic within the area of responsibility of Maritime Safety Centre in Gdynia and/or VTS Gulf of Gdansk.

This study clarifies the mental workload of VTS Operator; by understanding their characteristics during carrying out their task, with a physiological index. The objective is to determine VTS Operators’ mind stress that might trigger any human error based on their mental workload during their watches. For this purpose, Heart Rate Monitor (HRM) is utilized as physiological index. The VTS Operators fitted the HRM and all of them have experience as a Master Mariner. During the all experiments, their heart rates and behaviours were recorded on the Event Record Form based on the time scale. After getting the heart rate variability, it is matched with the events, and then Operators’ behaviour is understood as the mental workload due to such kinds of events. Furthermore, these workloads include the Operators’ mind stress and their decisions under these circumstances. This study provides the fundamental information for understanding the VTS Operators’ characteristics.
