“…Testbeds have been developed in many maritime projects to test specific technologies, e.g. in the North Sea [1], the Baltic Sea [2][3][4], the Ionian Sea [5], the Adriatic Sea [6], the Malacca Strait [7] and Japan [8]. Each of these testbeds is specialized by its individual applications.…”

The steadily increasing complexity of maritime systems substantially raised the need for advanced verification and validation (V&V) as well as certification methods. Extensive simulation-based certification adds new opportunities to existing physical testing. Compared with simulation, field tests are extremely time-consuming and therefore expensive. Furthermore, relevant close-range situations between ships or environmental impacts (e.g. certain types of bad weather situation) are impossible to perform in the field for safety reasons and the uncontrollability of the environment or simply the amount of experiments needed. Systems in the maritime domain (like products for navigation assistance, sensors, communication equipment etc.) are typically not used isolated but as part of a complex setup. More and more sensors and actuators are integrated to provide data for various systems or information services on board a ship and ashore. Since such systems are typically continuously evolving during their service lifetime, the development and maintenance of maritime systems (e.g. bridge systems) need to considered in its usage context that includes interconnected systems and external services, sensors and actuators. CPSoS (Cyber-Physical System of Systems) demand innovative approaches for distributed optimization, novel distributed management and control methodologies that can also deal with partially autonomous systems, and must be resilient to faults or cyber-attacks. In addition, CPSoS engineering no longer maintains the former strict separation between the engineering phases and actual operation. Instead, integrated approaches for the design-and operation-phase are required to cover the full lifecycle by modelling, simulation, validation, and verification (V&V). Thus, prospectively, it will be necessary to monitor the system formation and to conduct a final assessment of the system by means of a suitable application of test cases in a controlled and comprehensible manner. These systems have an emerging behavior and cannot entirely defined during the design phase. At this point it becomes apparent that conventional unit, integration and system tests are no longer sufficient to fully cover and validate the functional limits of Cyber-Physical System of Systems. An acceptable test coverage cannot be achieved with these methods for such systems. In this paper the authors present a use case of collision-regulation compliance checker to compare virtual (i.e. simulation-based) V&V, physical (i.e. in-situ testing) V&V and hybrid, mixed-reality V&V.

“…13 Both ENSI and ee-INS target at increasing the safety of maritime traffic using the Internet for route plan exchange and the ships receiving meteorological and oceanographic data and maritime safety information on the route. In Porathe et al, 14 the potential unintended consequences of ships sharing their planned routes via ee-INS service were evaluated using a system simulator. However, a systematic quantification of the effects of a system such as ENSI or ee-INS on navigational safety has not been conducted yet.…”

When considering the implementation of a novel risk-control option, the estimation of its possible effects often relies on expert elicitation. This article presents an expert-knowledge-based preliminary assessment of how the deployment of Enhanced Navigation Support Information navigation service would affect the ship collisions and groundings in the Gulf of Finland. Experts probabilistically assess the service's direct effects on various factors, which are then utilized in collision and grounding probability Bayesian network models. The results indicate that implementing the Enhanced Navigation Support Information service could decrease the number of accidents. However, a comparison of the model outcomes to the experts' qualitative opinions reveals some discrepancies, which suggest that the elicitation procedure or the applied models might require further improvement. Nevertheless, with the proposed Bayesian approach, the model can be updated and uncertainties in the estimates reduced after more evidences are available later from longer and wider use of the service.

“…ECDIS is a safety-relevant and software-based system with multiple options for display and integration, which is used to meet chart carriage requirements (Rutkowski, 2018). Much of the current literature on ECDIS pays particular attention to route planning, collision avoidance (Porathe et al, 2013;Tsou, 2016;Köckritz et al, 2016), performance analysis and development of ECDIS (Kastrisios and Pilikou, 2017;Žuškin et al, 2017;Wan et al, 2005), and training research (Legieć, 2016;Brčić et al, 2019). Gyro compass has become an indispensable instrument in almost all merchant ships or naval vessels due to its ability to detect the direction of true North.…”

The increasing attention to the improvement and continuous enhancement of navigational safety has led to a high standard of navigation systems and the introduction of new technologies. Although several conventions, recommendations, guidelines, and performance standards for navigational equipment are set out by the International Maritime Organization (IMO), unexpected defects on this equipment may still occur on board. Any defect on this equipment may cause both accidents and commercial loss. This paper presented A fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) technique to assess factors that may cause navigational equipment defects, considering the academic and industrial gaps. Five homogeneous experts were asked to evaluate the relationship among the factors with respect to the linguistic scale. After the factors were ascertained and evaluated, preventive measures for most important factors were recommended in the view of experts’ opinions in order to minimize and avoid their effect. The findings of the study will contribute to understanding the causes of navigational equipment defects and provide a basis for the continuous safety process of the ship’s bridge operations in a comprehensive aspect.
