Opis:
Poor lookouts, i.e. one of errors in situation awareness, are pointed out as the major cause of collisions of ships, through investigations of collision accidents. In order to evaluate safety measures for preventing collisions caused by poor lookouts, it is necessary to understand background factors, so called “contexts”, of errors in situation awareness regardless of occurrence of collisions. The purpose of this study is to point out the possible significant contexts, using a navigator’s situation awareness model. As a result, we point out that one of the possible significant contexts is a problem on judgment of priority levels of other ships with regard to attention.

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.

Opis:
Maritime subsea operations have increased significantly in size and complexity during the last decades as a result of the advances in the offshore oil industry. Despite the fact that subsea operations can involve hundreds of personnel, working together with complex technology, limited research can be found regarding the operations in the available literature. This study aims to analyze a routine subsea operation using the Distributed Situation Awareness (DSA) framework and understand how the operators on board maintain their DSA in routine operations through a case study. In order to understand how the operation unfold in complex sociotechnical systems and how situational awareness (SA) is distributed across agents and artefacts, the theoretical framework of DSA can be useful as the focus is on the interactions at a systemic level. To achieve the research objectives, a combination of qualitative methods was utilized to illustrate DSA on board a subsea vessel. Initially an observation was conducted during a live subsea survey operation to capture the interaction between personnel and instruments. Furthermore, all observed personnel were subjected to retrospective interviews to elicit further knowledge of the operation. Finally, the data was analyzed according to the propositional network approach and Hierarchical Task Analysis (HTA). The result of this study portrays the SA of a subsea survey operation as propositional networks for the main phases identified in the HTA. The main findings of the study show a significantly difference in DSA among the Bridge personnel and personnel located in the Online Control Room (ONCR). Furthermore, it was found that the dynamic of the system allowed personnel to have different level of DSA without jeopardizing the overall operation. Finally, the summary of the findings provides a basic understanding of how a routine subsea survey operation unfolds.

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:
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:
Situation awareness is a crucial factor in decision-making. It involves monitoring and identification of relationships among the state changing objects in collaborative dynamic environments. In the domain of airport security a critical need is to support security operators in real-time management of risky airside scenarios. This work relies on a fuzzy cognitive ontology-based approach to model situation awareness and introduces an agent-based distributed evaluation architecture to address the problem. Specifically, in order to model situation awareness this work instantiates and integrates two assessed ontological meta-models, Situation Theory Ontology (STO) and Saw Core Ontology (SAW), extended to cope with uncertainty when modeling relations among objects occurring in the addressed dynamic environment. Many task-oriented soft computing agents are in charge of monitoring the modeled situations while distributing the information evaluation process leads to achieving better real-time like performance.

Opis:
One of the features determining the strength of troops is command and control. The quality of command and control is determined by the quality of the command and control systems (C2S). The Czech Armed Forces are developing tactical command and control systems (TC2S) for the Ground and Air Forces. The TC2S were a little bit separately developed. Now, we want to use the benefit of shared situation awareness. The concept of Network Centric Warfare is a solution of this problem. The integration of both TC2S's is its main objective. To apply this concept, separate C2S's of different units are integrated into one logical system, into one joint C2S. Thus it is possible to create the common operation picture for all units of the task force.

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:
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:
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.

UK-Test is one of the psychological test for understanding the personality. In this paper, we considered whether UK-Test is effective methods for OICNW in order to check the ability of non-technical skills using UK-Test results and collision avoidance manoeuvre experiments results on the ship handling simulator (hereinafter, referred to as the simulator). Specifically, we analysed the correlation between UK-Test results and collision avoidance manoeuvre experiments results on the simulator. We also created the collision avoidance scenario that required a lot of the ability of non-technical skills as OICNW, and evaluated the ability of non-technical skills of OICNW.

The basis of considerations are the results of a survey conducted among 120 students of first and second degree (undergraduate and graduate) of the Faculty of Polish and Classical Philology of Adam Mickiewicz University in Poznań. It turns out that the young humanists understand very well the concept of taboo, they can identify topics covered by the taboos and rules for compliance. They do not indicate either that the taboo passed to the sphere of phenomena recessive.
