Opis:
The objective of this paper is to highlight the needs for improved access to high quality maritime data and information in the Arctic, and the need to develop maritime communication infrastructure with at least the same quality, in terms of availability and integrity, as in other more centralized areas. The foreseen Arctic ice meltdown is expected to provide new maritime transport corridors within relatively short time, and there is an urgent need to prepare for this, to ensure safe operations at sea and to protect the vulnerable Arctic environment. This paper points out some of these needs by presenting a case from a former accident in the Arctic sea. The case shows how the lack of proper information and data complicates the emergency operation. Some possible solutions to the challenges are proposed, and finally the paper briefly discusses the IMO e-Navigation concept in light of the Arctic challenges.

Opis:
Modular Integrated Navigation Systems (INS) according to the revised IMO performance standards on INS combine and integrate the validated information of different sensors and functions and allow the presentation on the various displays according to the tasks. The aim of the investigations discussed within this paper was to assess the advantages of an INS design compared to a traditional bridge layout with respect to the execution of collision avoidance and route monitoring tasks. The Situation Awareness Global Assessment Technique (SAGAT) approach was applied to assess Situation Awareness (SA) during these operations while bridge design and out of window visibility were manipulated. Additionally, workload was measured by NASA-TLX with its six subscales. The experiment was conducted in a full immersive simulation environment with 26 experienced mariners. The results indicate that SA is significantly higher with the INS bridge design in the reduced visibility condition compared to the traditional bridge design. Also, tendencies were found that workload and subdimensions are influenced by bridge design and visibility conditions.

Opis:
Although SOLAS still requires nautical paper charts on pleasure crafts, more and more sailors prefer navigating digitally. What are the impacts on their spatial abilities? We conducted a field experiment at the Baltic coast and two simulator experiments with altogether 40 sailors. Participants plotted and/or piloted routes either in the classic manner on paper charts or digitally on an ECS. We assessed the situation awareness, the cognitive map, and (for the simulator only) the wayfinding with and without the navigation media. We found that digital navigation significantly impaired the cognitive map. Its impact on situation awareness, however, depended on previous navigation habits: Only sailors who used their paper charts regularly and actively benefitted from the ECS. We concluded that ECS navigation with its high level of automation lastingly alters spatial perception at sea and impairs orienting. With the vulnerable electricity supply on sailboats, this is a safety issue for shipping.

Opis:
Pilotage is considered as the most critical leg of navigation and a complex operation in maritime domain. In this paper, we argue that Distributed Situation Awareness (DSA) is an important construct in pilotage as the information required to carry out operations is distributed between agents and artefacts. We identify the central themes from the theory of DSA which are useful in describing modern day complex socio-technical systems. Further, based on the central themes, we propose guidelines for evaluating bridge teams involved in pilotage operations.

Opis:
The first ever attempt at fully autonomous dock-to-dock operation has been tested and demonstrated successfully at the end of 2018. The revolutionary shift is feared to have a negative impact on the safety of navigation and the getting of real-time situation awareness. Especially, the centralized context onboard could be changed to a distributed context. In navigation safety domain, monitoring, control, assessment of dangerous situations, support of operators of decision-making support system should be implemented in real time. In the context of autonomous ships, decision-making processes will play an important role under such ocean autonomy, therefore the same technologies should consist of adequate system intelligence. At the same time, situation awareness is the key element of the decision-making processes. Although there is substantial research on situation awareness measurement techniques, they are not suitable to directly execute quantitative processing for the situation awareness of autonomous ships navigation. Hence, a novel quantitative model of situation awareness is firstly proposed based on the system safety control structure of remotely controlled vessel. The data source is greatly limited, but the main result still indicates that the probability of operator lose adequate situation awareness of the autonomous ship is significantly higher than the conventional ship. Finally, the paper provides a probabilistic theory and model for high-level abstractions of situation awareness to guide future evaluation of the navigation safety of autonomous ships.

Opis:
Many ship collisions have been caused by a navigator’s error in the situation awareness (SA) of the navigator. In congested sea areas, navigators classify ships on the basis of different priority levels. For safety measures against ship collision, it is imperative for navigators to recognize the ships with high priority levels. In previous study, navigators’ SA was measured in a ship maneuvering simulator using the Situation Awareness Global Assessment Technique (SAGAT). From the results of the previous study, we proposed a new risk category, named as “attention area,” that covers ships with high priority level in the SA of navigators. However, the extent of data for navigators’ SA was limited. Therefore, the purpose of this study is to confirm the validity of the category using additional data of navigators SA. In this study, the validity of the proposed category was confirmed, and a limit line surrounding ships with high priority levels was identified. In addition, it was evident that the category was able to detect ships with high priority level around the time when the collision avoidance was performed.
