A model of factors influencing deck officers' cyber risk perception in offshore operations

Offshore operations onboard vessels are increasingly reliant on digitalization, integration, automation, and networked-based systems, which creates new dimensions of cyber risks. The causes of cyber incidents often include complex relationships between humans and technology, and in offshore operations, the onboard crew can be both a cyber security risk and a vital resource in strengthening the cyber security. This makes the behaviour of the decisionmakers onboard important in both preventing and handling cyber risks at sea. By use of in-depth interviews and the constant comparative analysis (CCA), this paper investigates factors influencing deck officers’ cyber risk perception in offshore operations and presents a contextual model of these factors. The model indicates that deck officers’ cyber risk perception can be affected by a feeling of distance towards cyber risks, being more restricted in their working environment because of digitalization, and trust in their reliable cyber-physical systems and suppliers. Further, targeted cyber risk mitigation measures should be implemented on multiple levels in shipping companies. The measures may benefit from focusing on increased risk communication, operational training, awareness campaigns, vessel-specific procedures, and policies, in addition to increased communication from management regarding the demand for digitalization. With this approach, the contextual model can contribute to the ongoing work of developing targeted measures for cyber risk mitigation in the maritime domain and can be used as a point of departure for further studies to discover additional nuances and factors within cyber risk perception in this domain.publishedVersio

Assessing the effectiveness of direct gesture interaction for a safety critical maritime application

Multi-touch interaction, in particular multi-touch gesture interaction, is widely believed to give a more natural interaction style. We investigated the utility of multi-touch interaction in the safety critical domain of maritime dynamic positioning (DP) vessels. We conducted initial paper prototyping with domain experts to gain an insight into natural gestures; we then conducted observational studies aboard a DP vessel during operational duties and two rounds of formal evaluation of prototypes - the second on a motion platform ship simulator. Despite following a careful user-centred design process, the final results show that traditional touch-screen button and menu interaction was quicker and less erroneous than gestures. Furthermore, the moving environment accentuated this difference and we observed initial use problems and handedness asymmetries on some multi-touch gestures. On the positive side, our results showed that users were able to suspend gestural interaction more naturally, thus improving situational awareness

Towards an understanding of operator focus using eye-tracking in safety-critical maritime settings

In this paper we report on our investigations into determining foci of attention for operators during safety-critical maritime operations, in this case a dynamic positioning (DP) operation. We monitored operators carrying out operations in ship simulators while wearing eye-tracking equipment. The eye-tracking was carried out during a standard operation with normal sea conditions (2-3 m wave height and no significant wind force). For the next iteration of experiments that will be reported in our next publication, it will then be possible to test the correlation between standard operations and operations with environmental effects introduced. These investigations led to an understanding of where operators focus, for how long and estimated their pupil dilation during these operations to investigate if it can correlate with critical parts of the operation. We also investigated the difference between trainee operators and operators with considerable experience. Results are presented along with a discussion of lessons for the design and placement of computer displays and equipment for safe operations in ship bridge environments
