Opis:
Within the last thirty years, the range and complexity of methodologies proposed to assess maritime risk have increased significantly. Techniques such as expert judgement, incident analysis, geometric models, domain analysis and Bayesian Networks amongst many others have become dominant within both the literature and industry. On top of this, advances in machine learning algorithms and big data have opened opportunities for new methods which might overcome some limitations of conventional approaches. Yet, determining the suitability or validity of one technique over another is challenging as it requires a systematic multicriteria approach to compare the inputs, assumptions, methodologies and results of each method. Within this paper, such an approach is proposed and tested within an isolated waterway in order to justify the proposed advantages of a machine learning approach to maritime risk assessment and should serve as inspiration for future work.

Opis:
The recent rapid improvement of nautical equipment functionality allows one to better observe and predict the dangers related to seamanship. However, these new features come with added complexity, and large amounts of information can overwhelm vessel crews and fleet operation centers, and the current state-of-the-art tools cannot filter out only the most important data for a given time and location. This paper presents the concepts and the algorithms of a software suite that provides a user with problem-oriented advice about a particular risk endangering a vessel and its crew. Based on the calculated navigational dangers and their predicted development, actionable guidance is proposed in an easy-to-understand human language. The quality of good seamanship is improved by a holistic approach to vessel installation, automated fleet operation center priority queuing, and the evaluation of crew performance during simulator training and daily operations. Both the software user interface, as well as the insights provided by the algorithm, are discussed.

Opis:
We wish to predict when an accident or tragedy will occur, and reduce the probability of its occurrence. Maritime accidents, just like all the other crashes and failures, are stochastic in their occurrence. They can seemingly occur as observed outcomes at any instant, without warning. They are due to a combination of human and technological system failures, working together in totally unexpected and/or undetected ways, occurring at some random moment. Massive show the cause is due to an unexpected combination or sequence of human, management, operational, design and training mistakes. Once we know what happened, we can fix the engineering or design failures, and try to obviate the human ones. We utilize reliability theory applied to humans, and show how the events rates and probability in shipping is related to other industries and events through the human involvement. We examine and apply the learning hypothesis to shipping losses and other events at sea, including example Case Studies stretching over some 200 years of: (a) merchant and fishing vessels; (b) oil spills and injuries in off-shore facilities; and (c) insurance claims, inspection rules and premiums. These include major losses and sinkings as well as the more everyday events and injuries. By using good practices and achieving a true learning environment, we can effectively defer the chance of an accident, but not indefinitely. Moreover, by watching our experience and monitoring our rate, understand and predict when we are climbing up the curve. Comparisons of the theory to all available human error data show a reasonable level of accord with the learning hypothesis. The results clearly demonstrate that the loss (human error) probability is dynamic, and may be predicted using the learning hypothesis. The future probability estimate is derivable from its unchanged prior value, based on learning, and thus the past frequency predicts the future probability. The implications for maritime activities is discussed and related to the latest work on managing risk, and the analysis of trends and safety indicators.

Opis:
A paradigm shift is presently underway in the shipping industry promising safer, greener and more efficient ship traffic. In this article, we will look at some of the accidents from conventional shipping and see if they could have been avoided with autonomous ship technology. A hypothesis of increased safety is often brought forward, and we know from various studies that the number of maritime accidents that involves what is called “human error” ranges from some 60‐90 percent. If we replace the human with automation, can we then reduce the number of accidents? On the other hand, is there a possibility for new types of accidents to appear? What about the accidents that are today averted by the crew? This paper will present a method to assess these different aspects of the risk scenarios in light of the specific capabilities and constraints of autonomous ships.

Opis:
Marine transportation is the most important transport mode of in the international trade, but the maritime supply chain is facing with many risks. At present, most of the researches on the risk of the maritime supply chain focus on the risk identification and risk management, and barely carry on the quantitative analysis of the logical structure of each influencing factor. This paper uses the interpretative structure model to analysis the maritime supply chain risk system. On the basis of comprehensive literature analysis and expert opinion, this paper puts forward 16 factors of maritime supply chain risk system. Using the interpretative structure model to construct maritime supply chain risk system, and then optimize the model. The model analyzes the structure of the maritime supply chain risk system and its forming process, and provides a scientific basis for the controlling the maritime supply chain risk, and puts forward some corresponding suggestions for the prevention and control the maritime supply chain risk.

Opis:
Ubezpieczenia morskie są historycznie najstarszym działem ubezpieczeń majątkowych sięgającym swymi korzeniami do starożytności. Ubezpieczenia morskie znacznie wyprzedziły rozwój ubezpieczeń lądowych, gdyż pierwsze przepisy prawne normujące umowę ubezpieczenia morskiego pochodzą ze średniowiecznych ośrodków handlu morskiego, m.in. Barcelony, Genui i Wenecji. W Polsce ubezpieczenia morskie zostały zapoczątkowane na przełomie XVII i XVIII wieku. Z uwagi, iż zwiększały pewność obrotu morskiego i służyły do zabezpieczenia transakcji kredytowych, w XIX i XX wieku stanowiły ważny czynnik rozwoju działalności gospodarczej na morzu. Uwzględniając powyższe niniejszy artykuł ma na celu poddanie analizie historyczno-prawnej przepisów prawa morskiego odnoszących się do obowiązków ubezpieczającego i odpowiedzialności ubezpieczyciela wynikających z kodeksowych regulacji w zakresie umowy ubezpieczenia morskiego, które obowiązywały w Polsce od 1918 r. do unifikacji prawa morskiego z 1961 r. W artykule zostanie podjęta próba wykazania czy polskie regulacje prawa morskiego bazowały na poniemieckich regulacjach w tym zakresie czy też były całkowicie odmienne oraz zostanie podjęta próba wskazania kierunku zmian w przepisach prawa morskiego w omawianym zakresie.
Marine insurance is historically the oldest branch of property insurance dating back to antiquity. Marine insurance predated the development of land insurance by a considerable margin, as the first legal provisions prescribing a marine insurance contract date back to the medieval centers of maritime trade, including Barcelona, Genoa and Venice. In Poland, marine insurance was initiated at the turn of the 17th and 18th centuries. As they increased the certainty of maritime trade and were used to secure credit transactions, they were an important factor in the development of maritime business in the 19th and 20th centuries. In view of the above, this article seeks to analyze the historical and legal provisions of maritime law relating to the duties of the policyholder and the liability of the insurer arising from the code regulations of the maritime insurance contract, which were in force in Poland from 1918 until the unification of maritime law in 1961. The article will attempt to show whether the Polish maritime law regulations were based on the post-German regulations in this respect or whether they were completely different. It will also attempt to indicate the direction of changes in maritime law regulations in this respect.

Opis:
The paper presents a model for risk analysis regarding marine traffic, with the emphasis on two types of the most common marine accidents which are: collision and grounding. The focus is on oil tankers as these pose the highest environmental risk. A case study in selected areas of Gulf of Finland in ice free conditions is presented. The model utilizes a well-founded formula for risk calculation, which combines the probability of an unwanted event with its consequences. Thus the model is regarded a block type model, consisting of blocks for the probability of collision and grounding estimation respectively as well as blocks for consequences of an accident modelling. Probability of vessbl colliding is assessed by means of a Minimum Distance To Collision (MDTC) based model. The model defines in anovel way the collision zone, using mathematical ship motion model and recognizes traffic flow as a non homogeneous process. The presented calculations address waterways crossing between Helsinki and Tallinn, where dense cross traffic during certain hours is observed. For assessment of, a grounding probability, a new approach is proposed, which utilizes a newly developed model, where spatial interactions between objects in different locations are recognized. A, ship at a seaway and navigational obstructions may be perceived as interacting objects and their repulsion may be modelled by a sort of deterministic formulation. Risk due to tankers running aground addresses an approach fairway to an oil terminal in Skoldvik, near Helsinki. [...]
W artykule przedstawiono model oceny ryzyka w transporcie morskim, w aspekcie kolizji statków oraz wejść na mieliznę. W modelu przyjęto jeden typ statków, tankowce do przewozu ropy naftowej, z uwagi na fakt, iż w przypadku wystąpienia kolizji lub kontaktu z dnem statek ten może stanowić bardzo poważne zagrożenie dla środowiska. W pracy przedstawiono dwa nowatorskie podejścia do modelowania prawdopodobieństwa wystąpienia powyższych wypadków. Model do oceny prawdopodobieństwa kolizji statków definiuje w nowy sposób strefę kolizji, w oparciu o właściwości manewrowe statku oraz jego hydrodynamikę. Intensywność ruchu morskiego na analizowanym akwenie modelowana jest w oparciu o proces niestacjonarny, w przeciwieństwie do istniejących modeli. Model oceny prawdopodobieństwa wejścia na mieliznę wykorzystuje model grawitacyjny, który wyznacza bezpieczny obszar manewrowy dla danego statku i danego akwenu. W modelu tym statek i otaczające go płycizny traktowane są jako masy, wzajemnie na siebie oddziaływujące. Obydwa modele wykorzystują dane o ruchu statków zarejestrowane w systemie automatycznej identyfikacji statków (AIS). Analiza ryzyka przeprowadzona została dla dwóch wybranych akwenów w Zatoce Fińskiej. Jako konsekwencje wypadku przyjęto model kosztów, skonstruowany w oparciu o dane statystyczne z międzynarodowego funduszu IOPCF, który pokrywa koszty w związku z rozlewem olejowym na morzu.

Opis:
The starting point of the paper is the recognition of the growing threat of cyber-attacks to commercial maritime. Constantly growing dependency on technology has obvious advantages, on the other hand, however, it makes commercial maritime vessels progressively more vulnerable to cyber-crime, including GPS signal interference, malware attacks or even gaining control over ships’ systems and networks. The main objective of the paper is to present and discuss the Guidelines on Cyber Security Onboard Ships developed by the International Maritime Organization, including best practices for implementation of cyber risk management. The article’s goal is to summarize the guidelines and to familiarize the reader with the reasons why and the methods how they should be implemented. The paper is concluded with an example how the Guidelines can be adopted by national authorities, i.e., a brief presentation of “Code of Practice: Cyber Security for Ships” – a document developed by the British government that transposes the IMO guidelines.

Opis:
As a result of the last decades development of technology and increased connectivity of maritime vessels, the need for maritime cyber security is undoubtedly present. In 2017, IMO officially recognized “… the urgent need to raise awareness on cyber threats and vulnerabilities to support safe and secure shipping, which is operationally resilient to cyber risks”. Thus, Maritime Cyber Resilience is seen as key by IMO in the improvement of the maritime cyber security. It is assumed that human error is the cause of more than half successful cyber-attacks. If technology somehow fails, in example because of a cyber threat, the human is expected to handle the problem and provide a solution. It is therefore necessary to focus on the human aspect when considering maritime cyber threats. This paper aims to provide a working definition of “Maritime Cyber Resilience”. Further, the paper argues why the human should be a focus of study, as the human is at the sharp edge in a potential maritime cyber emergency.

Opis:
Contemporary maritime shipping is subject to a large number of constraints given by tight shipping schedules and very low margins. Additionally, problematic areas with increased security needs dynamically changing in time, combined with seasonal oceanographic and meteorological conditions pose a challenging voyage planning problem. In this work we present a risk-aware voyage planner taking into account spatio-temporal environmental conditions. The planner is based on a graph-based search algorithm A* . We discretize the required area into a graph, we store various layers of information into the edges of the graph (such as risk and weather conditions) in a form of numeric weights and we define a bi-objective planning problem with a tradeoff between security and duration of the voyage. The nature of the algorithm guarantees a complete and optimal solution in a form of an optimized voyage with respect to the criterion function composed of the two weighted components, i.e, duration and security of the voyage. We demonstrate the approach on our area of interest: Indian Ocean. We use NATO piracy activity risk surface as the risk layer and we compute all transit voyages between relevant routing points in the area. Finally, thanks to the discretization of the problem, we are able to integrate corridors imposed by the shipping authorities and evaluate additional what-if scenarios with extended corridor systems. The resulting planner is exposed to the public using a web service with an easy interface requiring start time of the voyage and the origin and the destination point of voyage. Combined with an expressive visualization, this tool demonstrates the capabilities of the proposed solution.

Opis:
In the maritime domain, the risk is evaluated within the framework of Formal Safety Assessment (FSA), introduced by International Maritime Organization in 2002. Although the FSA has become internationally recognized and recommended method, the definition, which is adopted there, to describe the risk, seems to be too narrow to reflect properly the actual content of the FSA. Therefore this article discusses methodological requirements for the risk perspective, which is appropriate for risk management in the maritime domain with the special attention to maritime transportation systems (MTS). This perspective considers risk as a set encompassing the following: the set of plausible scenarios leading to an accident, the likelihoods of the unwanted events within the scenarios and the consequences of the events. These elements are conditional upon the available knowledge about the analyzed system, and understanding of the system behaviour, therefore these two are inherent parts of risk analysis, and need to be included in the risk description.

Opis:
An increase in the complexity of systems onboard ships in the last decade has seen a rise in the number of reported maritime cyber-attacks. To tackle this rising risk the International Maritime Organization published high-level requirements for cyber risk management in 2017. These requirements obligate organisations to establish procedures, like incident response plans, to manage cyber-incidents. However, there is currently no standardised framework for this implementation. This paper proposes a Cyber Emergency Response Procedure (CERP), that provides a framework for organisations to better facilitate their crew’s response to a cyber-incident that is considerate of their operational environment. Based on an operations flowchart, the CERP provides a step-by-step procedure that guides a crew’s decision-making process in the face of a cyber-incident. This high-level framework provides a blueprint for organisations to develop their own cyber-incident response procedures that are considerate of operational constraints, existing incident procedures and the complexity of modern maritime systems.

The paper presents the overall risk management state for the crude oil tanker fleet, evidenced by EMSA and other international marine organisations. Based on historical statistical data related to fleet size, accident reports, amount of oil spilled on the sea and the economic value of the crude oil transport business, the risk acceptance criteria are evaluated. The Formal Safety Assessment is further used for a systematic assessment of risk, where potential hazards are analysed with structured methods (HAZID) and represented in event trees. The paper studies three risks: PLL (potential loss of lives), PLC (potential loss of containment) and PLP (potential loss of property). A general approach is presented and discussed with a particular focus on the evolution of risk acceptance in recent decades and evaluations of risk F-N curves for different tanker sizes.

Opis:
Large-scale distributed transportation systems can pose various risks in terms of fatalities, environmental pollution, or loss of property. In particular, accident where a vehicle carrying large number of passengers is involved may pose a high risk with respect to human casualties, moreover it will immediately raise a public and political concern. This is an issue in case of maritime transportation systems (MTS), as the biggest ships nowadays can carry up to 8500 people at once (m/s Oasis of the Seas). Thereby lot of effort has been put to increase safety of ships carrying passengers; however the holistic approach to model and manage the risk existing in the MTS is still missing. This paper makes an attempt to fill this gap, by presenting a data-driven model evaluating risk level in the existing MTS and by introducing a systematic methodology for mitigating the risk. Moreover the MTS operating in the Gulf of Finland under non-ice conditions is addressed, where heavy passenger traffic is observed.

Opis:
In many sea areas there is significant recreational activity, with many sailing vessels and motor boats navigating, especially in coastal areas. Search and Rescue (SAR) organizations ensure the safety of people at sea, and are relatively frequently called to perform rescue or assistance missions to people in distress. Apart from the importance of adequate operational planning and training, rescue organizations benefit from establishing a robust, effective and cost-efficient response system. Risk-informed capacity planning can serve as a decision-support tool for determining the number and location of the required search and rescue units (SRUs). The purpose of this paper is to present such a risk-informed approach, which combines analysis of historic accident and incident data of recreational boating with information derived from Geographic Information System (GIS) methods. The method is applied to a case study focusing on the risk-informed capacity evaluation of the voluntary search and rescue services in the Finnish part of the Gulf of Finland. Results indicate that the response performance for recreational boating incidents is very good in most areas.

Due to the unique geographic location, complex navigation environment and intense vessel traffic, a considerable number of maritime accidents occurred in estuarine waters during recent years which caused serious loss of life, property and environmental contamination. Based on the historical data of maritime accidents from 2003 to 2012, which is collected from Shenzhen Maritime Safety Administration, this paper conducted a risk analysis of maritime accidents by applying Bayesian network and fault tree analysis. First a Bayesian network model was introduced to describe the consequence of accidents based on the accident investigation report. Then fault tree analysis was applied to estimate the probability on the basis of accident statistics and ship traffic flow. Finally the risk of maritime accidents in Shenzhen Waters was depicted through the consequence multiplied by the probability of an accident.

Opis:
Over the recent years, ship traffic in the polar areas has increased. There is reason to believe that this traffic, and especially the cruise traffic, will increase further as the ice retracts towards the poles. There is also reason to believe that with the continued focus and exposure of the Polar Region, the cruise tourism to the region will grow. The increased presence in the polar areas will create positive repercussions for several actors, both on sea and land. There will, however, also be challenges associated with the growing presence in the polar areas. Vessels will be operating at long distances to other vessels and land infrastructures. These vessels will also be operating in climate and conditions that will put extra pressure on both vessel and crew. These challenges need to be solved in order for the ship industry to operate safely in the Polar Region. To ensure that companies operating in these areas identify and manage these challenges, the International Maritime Organization (IMO) developed the Polar Code (2017) with the intent of increasing the safety for vessels operating in polar waters, and to reduce the impact on humans and environment in this remote, vulnerable and harsh area. This code defines a number of requirements, with which the vessels should operate in accordance with. In this paper, we reveal which challenges the vessel and its crew need to deal with when navigating in polar waters. The challenges will be analysed and assessed through the use of a preliminary qualitative risk analysis to determine the potential hazards the vessel is exposed to under operations in polar waters, and to find out what level of risk the different hazards represents for the vessel and its crew. The main objective of the paper is to find out how the risk levels can be reduced, with particular focus on the use of simulator training as a risk reducing measure. The final goal is to measure the risk towards acceptance criteria, which have been determined prior to conducting the analysis.

Opis:
Present stability regulations developed over the years by IMO reached definite conclusion with the adoption of the Revised Draft of the Intact Stability Code. The criteria included there are design criteria of the prescriptive nature, based mainly on statistics of stability casualties. Currently IMO is considering development of criteria based on ship performance. Concept of such criteria is, however, at present not agreed. The criteria are working comparatively well with regard to the majority of conventional ships, however advent of very large and sophisticated ships of non-conventional features caused that those criteria may be inadequate. The author advances the idea consisting of application of safety assessment and risk analysis using holistic and system approach to stability. Safety against capsizing (or LOSA accident) is a complex system where design, operational, environmental and human factors have to be taken into account. Although this seems to be a very complex task, in the opinion of the author it may be manageable and could be applied for safety assessment of highly sophisticated and costly ships.

Opis:
This paper aims at evaluating the collision risk between the encountering vessels under time- -variant CPA situations and then assessing the maritime traffic characteristics. Radar and AIS data are collected from Mokpo VTS in Korea. All crossing vessels that are navigating within CPA 1 miles of Mokpo-Gu waterway are analyzed. The maritime traffic characteristics is analyzed by surveying the distribution of CPA as a function of TCPA. To make it clear, the traffic operating rate in the Mokpo waterway is also computed. The averages of CPA and TCPA were observed until the encountered vessels pass safety each other after they come in a certain ship domain. As a consequence, the distribution of CPA as a function of TCPA gives a useful information to evaluate the maritime traffic safety.
Celem artykułu jest ocena ryzyka kolizji statków w funkcji zmiany wartości czasu do kolizji, a na tej podstawie oszacowanie charakterystyk determinujących ruch morski. Dane z radarów oraz systemu AIS zostały zarejestrowane w systemie VTS Mokpo w Korei. Przeanalizowano wszystkie przypadki przecinania się tras statków na podejściu do Mokpo-Gu w przypadku, gdy odległość minimalna (CPA) była mniejsza niż jedna mila morska. Charakterystyka ruchu morskiego opisana została poprzez wyznaczenie rozkładu wartości największego zbliżenia statków jako funkcji czasu do nadmiernego zbliżenia (TCPA). Dla pełnej jasności obliczono również współczynnik przepustowości drogi wodnej Mokpo. Opisano średnie wartości odległości największego zbliżenia oraz czasu do wystąpienia CPA bez względu na przekroczenia granic domeny obserwowanych statków. W konsekwencji wyznaczono rozkład wartości CPA jako funkcję TCPA, co okazuje się użyteczne dla oceny bezpieczeństwa ruchu morskiego.

Opis:
Basic concepts of the safety analysis of ageing multistate systems are introduced. The system components and the system multistate safety functions are defined. The mean values and variances of the multistate systems’ lifespans in the safety state subsets and the mean values of their lifespans in the particular safety states are defined. The multistate system risk function and the moment of exceeding the critical safety state are introduced. A series safety structure and a parallel-series safety structure of the multistate systems with ageing components are defined and their safety functions are determined. The multistate system safety models are applied to the prediction of safety characteristics of a maritime ferry.

Opis:
The maritime transportation system is increasingly a target of cyber attacks. This paper describes a taxonomy that supports the creation of adversarial cyber models, risk mitigation, and resiliency plans as applied to the maritime industry, using the Automatic Identification System as a specific illustration of the approach. This method has already been applied to the aviation sector; retooling it for a maritime example demonstrates its broad applicability to the transportation sector, in general.

Opis:
The Baltic Sea is crisscrossed by several dense vessel traffic routes. Growing shipping traffic increases the likelihood of collisions. A quantitative analysis of the impact of fishing vessel traffic streams on streams of merchant vessel traffic aims to identify areas of intense traffic of this type and to assess the potential risks. The identification of intersections of fishing vessel routes and merchant shipping traffic allows us to identify spots of potential collisions. The analysis made use of the IALA IWRAP Mk2 program and AIS data collected from April 1, 2013 to March 31, 2014.

Opis:
The sea ice in the Arctic has shrunk significantly in the last decades. The transport pattern has as a result partly changed with more traffic in remote areas. This change may influence on the risk pattern. The critical factors are harsh weather, ice conditions, remoteness and vulnerability of nature. In this paper, we look into the risk of accidents in Atlantic Arctic based on previous ship accidents and the changes in maritime activity. The risk has to be assessed to ensure a proper level of emergency response. The consequences of incidents depend on the incident type, scale and location. As accidents are rare, there are limited statistics available for Arctic maritime accidents. Hence, this study offers a qualitative analysis and an expert-based risk assessment. Implications for the emergency preparedness system of the Arctic region are discussed.
