“…The same is true in control theory, where continuous feedback loops of information are necessary to maintain control and for a system to remain within its safety boundaries (Dekker and Pruchnicki 2014). Regulating the system depends thus on communication (Johansson and Persson 2009;Skyttner 2005), information processing, planning/adaptation and decision and is measured through the extent to which the system is achieving its intended goal (effectiveness), with a minimal use of resources (efficiency), and contributing to the goals of the higher-level system in which it is contained (efficacy) (Skyttner 2005).…”

“…The general systems theory of Cybernetics, which from the Greek means "steersman" or "rudder" (Miller 2012;Skyttner 2005;Woods and Hollnagel 2006), refers to a closed-loop feedback model in terms of maintaining control of a dynamic and complex system being steered, controlled and regulated towards the achievement of system goals (Miller 2012), allowing the system's behaviour and response to be better predicted (Skyttner 2005). The same is true in control theory, where continuous feedback loops of information are necessary to maintain control and for a system to remain within its safety boundaries (Dekker and Pruchnicki 2014).…”

Non-technical communication factors at the Vessel Traffic Services

This study done at the Vessel Traffic Services (VTS) explored how the VTS operators (VTSOs) communicated with ships and other actors in the maritime sociotechnical system and how decisions were made with regard to assisting traffic in maintaining safe passage in port areas, where most vessel movements are seen and accidents occur. The fieldwork was done during four independent visits to a VTS centre under the Swedish Maritime Authority, with a total sample of six VTSOs and one VTS instructor. The qualitative data were sorted and coded using a grounded theory approach. The data pointed at non-technical information processing and communication factors that play a role in decision-making and ultimately in safety. During protocol operations at the VTS, these factors influenced how VTSOs judged the skills of the vessels' bridge teams, and how they approached them. This is a time where much effort is being put into upgrading technological systems, and these will have the power to change the ways in which the maritime network obtains and processes information, as well as how they can communicate with each other. The further development of technological systems, work protocols and training programmes can benefit from taking the soft aspects of communication and the needs of the operators and their tasks into account for the enhancement of safety.

“…One possible way is to follow the image of a window over the areas and domains of interest and scan through the journal issues. Focusing on domains of application, it is possible to look for energy/nuclear production (CTW, 2 (4), 2000; CTW, 15 (1), 2013), process and chemical industry (Salo and Svenson 2003;Baranzini and Christou 2010), manufacturing industry (Barroso and Wilson 2000;Upton et al 2010), road transport (CTW, 8 (3), 2006a, b), maritime transport (Itoh et al 2001;van Westrenen and Praetorius 2014), rail transport (CTW, 8 (1), 2006a, b) and aviation (Dekker and Woods 1999;Masson and Koning 2001;Rashid et al 2013), household (CTW, 5 (1), 2003, healthcare (McCarthy and O'Connor 1999;Xiao and Sanderson 2013;Parush et al 2014) and social services and emergency management (Militello et al 2007;Kylesten and Nählinder 2011). Although in some cases the societal impact of certain events has increased the attention on specific issues (Johnson 2005), in general, the need to keep under attention the role of humans in managing systems and interacting with the actual control systems of real processes has always been favoured.…”

“…A holistic approach to the future of ship-shore cooperation has been proposed by Van Westrenen and Praetorius (2014), based on the principle of distributed vs centralized control. They postulate that "when resources become insufficient (e.g.…”

“…One key factor for successful ship-shore team work is found to be the ability of VTS Officers to perceive and understand the navigational challenges in the same manner as the Deck Officers (Praetorius, Westrenen, Michell & Hollnagel, 2012;Praetorius, Bruno & Lützhöft, 2010;Van Westrenen & Praetorius, 2014;Praetorius & Lützhöft, 2012;Porathe & Brödje, 2015).…”
