Opis:
In this paper, we discuss a software architecture, which has been developed for the needs of the System for Intelligent Maritime Monitoring (SIMMO). The system bases on the state-of-the-art information fusion and intelligence analysis techniques, which generates an enhanced Recognized Maritime Picture and thus supports situation analysis and decision-making. The SIMMO system aims to automatically fuse an up-to-date maritime data from Automatic Identification System (AIS) and open Internet sources. Based on collected data, data analysis is performed to detect suspicious vessels. Functionality of the system is realized in a number of different modules (web crawlers, data fusion, anomaly detection, visualization modules) that share the AIS and external data stored in the system’s database. The aim of this article is to demonstrate how external information can be leveraged in maritime awareness system and what software solutions are necessary. A working system is presented as a proof of concept.
Prezentowany artykuł omawia architekturę oprogramowania opracowanego na potrzeby projektu System for Intelligent Maritime Monitoring (SIMMO). System ten bazuje na najnowszych osiągnięciach w dziedzinach fuzji oraz inteligentnej analizy danych w celu generowania wzbogaconego obrazu sytuacji na morzu i wspomagania decyzji. SIMMO w sposób automatyczny łączy dane dotyczące ruchu morskiego z systemu AIS z danymi pochodzącymi z otwartych źródeł internetowych. Dzięki zebranym danym możliwa jest analiza w celu wykrycia podejrzanych zachowań na morzu. Funkcjonalność systemu stanowi wypadkową zawartych w nim modułów (ekstrakcja danych, fuzja danych, detekcja anomalii, wizualizacja) współdzielących dostęp do baz z danymi AIS oraz z zewnętrznych źródeł. Celem artykułu jest demonstracja sposobu wykorzystywania zewnętrznych informacji w systemach przeznaczonych do monitorowania ruchu morskiego, a także prezentacja działającego systemu.

Opis:
The article concerns integration and disambiguation of data related to the maritime domain. A developed system is described, which collects and merges data about several maritime-related entities (vessels, vessel types, ports, companies etc.) retrieved from different internet sources and feeds the data into a single database. This process is however not trivial. There are few challenges, which need to be faced to successfully conduct it. Firstly, in different sources, entities may be referenced to in different ways, for example, by using different text strings. Additionally, some of these references may be ambiguous, i.e. potentially the reference may point to more than one entity. To enable efficient analysis of data coming from different sources, such ambiguities must be resolved automatically as a preprocessing step, before the data is uploaded to the database and utilized in further computations. The aim of the disambiguation process is to assign artificial, unique identifiers to each entity and then, if possible, automatically assign these identifiers to each data item related to a given entity. In the article, developed methods for resolving such ambiguities are discussed and their evaluation is presented.

Opis:
This paper explores the use of machine learning and deep learning artificial intelligence (AI) techniques as a means to integrate multiple sensor modalities into a cohesive approach to navigation for autonomous ships. Considered is the case of a fully autonomous ship capable of making decisions and determining actions by itself without active supervision on the part of onboard crew or remote human operators. These techniques, when combined with advanced sensor capabilities, have been touted as a means to overcome existing technical and human limitations as unmanned and autonomous ships become operational presently and in upcoming years. Promises of the extraordinary capabilities of these technologies that may even exceed those of crewmembers for decision making under comparable conditions must be tempered with realistic expectations as to their ultimate technical potential, their use in the maritime domain, vulnerabilities that may preclude their safe operation; and methods for development, integration and test. The results of research performed by the author in specific applications of machine learning and AI to shipping are presented citing key factors that must be achieved for certification of these technologies as being suitable for their intended purpose. Recommendations are made for strategies to surmount present limitations in the development, evaluation and deployment of intelligent maritime systems that may accommodate future technological advances. Lessons learned that may be applied to improve safety of navigation for conventional shipping are also provided.

Opis:
This paper presents the key assumptions and preliminary research on an integrated system called ESABALT, for enhancing maritime safety, which incorporates the latest technological advances in positioning, e-Navigation, Earth observation systems and multi-channel cooperative communications. The most novel part of the ESABALT concept, however, is a focus on user-driven crowdsourcing techniques for information gathering and integration. The system will consist of a situational awareness solution for real-time maritime traffic monitoring via utilizing various positioning technologies; an observation system of the marine environment relevant to transportation and accidents including assessing the sea ice, oil spread, waves, wind etc.; and a methodology for context-aware maritime communication with cooperative, multi-channel capabilities. The paper presents the intelligent, novel, user-driven solution and associated services developed in ESABALT for enhancing the maritime safety in the whole Baltic area.

Opis:
The maritime industry is a high-risk industry, which constantly has to make decisions in a rapidly changing environment. Therefore, understanding the essence of "situational awareness" is very important for making the right decision. In this regard, it is obvious that a correct situation analysis, based on a theoretical basis, creates the proper prerequisites for making the right decision in a developing situation, and vice versa. Considering this fact, this article proposes to study the factors that influence this phenomenon, their regularities and connections. It presents the data of a survey among seafarers to determine the level of understanding of situational awareness as a predominant component of the human factor in most accidents in the maritime industry.

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:
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.

Safety of crew, passengers, cargo and vessel is the most important aspect in terms of navigation. Boat Captain’s is responsible for the safety of vessel of less than 35GRT. The primary reason while MARINA conducting the MBSTC Training with Typhoon Awareness together with the ISCOF to be sure that they are enough knowledge in terms of safety at sea. Life is a very important to all of us that’s why the boat Captain must be aware about the safety of his crew, passengers, cargo and vessel. When disaster and emergency happen onboard you must know what to do. Based on this premise, the objective of this study is to train the Boat Captain and Motormen in Medical First Aid, Advanced Fire Fighting, Personal Survival Techniques and Collision Regulations. The study employed qualitative research using purposive sampling to gather the opinions and ideas of the respondents.

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.
