Incident Analysis

Under the International Safety Management (ISM) Code, shipping companies are required to build a Safety Management System and develop procedures that will regulate the incident analysis process. By these procedures, the shipping companies develop an incident analysis form and use it on all ships within their fleets. Although these forms serve a common purpose, their structure shows some differences between companies. Thus, time may be wasted when transferring the data or insufficient data may be obtained. This paper examines incident analysis forms used for tanker ships whose hazardous cargos make them of particular importance. The features of incident analysis forms used on tankers of a shipping company were specified, and the fuzzy analytic hierarchy process (FAHP) method presented their importance levels. Expert opinion was collected by a questionnaire. The results revealed that the highest priorities belong to the sections allocated for details about the ship and environmental conditions and root cause analysis technique. The least essential sub-criteria were related to the structure and variety of the forms. Based on the study results, which captured the current practice and the sector’s expectations, tanker shipping companies’ existing incident analysis forms could be revised. The revised documents would help to achieve complete information and prevent loss of time in information exchange between companies. Bringing a common approach to the analysis of incidents in tanker shipping would increase safety in the shipping industry.

In contrast to the conventional safety management principle, namely, safety-I, which focuses on “what goes wrong”, a new-born safety philosophy (safety-II) inspires people to investigate “how and why things go right”. In the present study, the cognitive difference and correlation between safety-I and safety-II in the maritime shipping industry are explored and investigated. For this purpose, a questionnaire is administered to survey seafarers and maritime experts, and semi-structured interviews are conducted to collect original data associated with safety-I and safety-II. Then, the data from seafarers and maritime experts are further processed by empirical statistical methods and fuzzy analytic hierarchy process (AHP) methodology. The results show that impacting factors associated with individual aspects are usually accepted as dominant with respect to views of safety-I, while organizational factors are more influential for safety-II, which is essential to developing an organizational resilience capacity. Based on the findings and discussions, potential safety countermeasures that integrate safety-I and safety-II are proposed in this article. The present study discusses the new-born safety-II perspective to elucidate the safety issues associated with maritime shipping operations, which can be seen as the main innovation of this work.

The International Maritime Organization (IMO) published the Guidelines on Maritime Cyber Risk Management in 2017 to strengthen cybersecurity in consideration of digitalized ships. As part of these guidelines, the IMO recommends that each flag state should integrate and manage matters regarding cyber risk in the ship safety management system (SMS) according to the International Safety Management Code (ISM Code) before the first annual verification that takes place on or after 1 January 2021. The purpose of this paper is to identify cybersecurity risk components in the maritime sector that should be managed by the SMS in 2021 and to derive priorities for vulnerability improvement plans through itemized risk assessment. To this end, qualitative risk assessment (RA) was carried out for administrative, technical, and physical security risk components based on industry and international standards, which were additionally presented in the IMO guidelines. Based on the risk matrix from the RA analysis results, a survey on improving cybersecurity vulnerabilities in the maritime sector was conducted, and the analytic hierarchy process was used to analyze the results and derive improvement plan priority measures.

Operational Errors

Shipping is a safety critical industry where operational errors may lead to maritime accidents involving property damage, loss of lives and environmental pollution. As part of the trend towards self-regulation, the International Maritime Organisation has adopted a worldwide International Safety Management Code which made ship managers responsible for workplace health and safety. This study, based on interviews in two Chinese shipping companies, examines how ship managers use ship visits to monitor shipboard safety management. Interviews with managers from company offices and crew members indicated that managerial ship visits mainly take the form of inspections that focus on low-trust surveillance and disciplinary action rather than genuine support, being based on the safe person rather than the more effective safe place approach. From the perspective of crew members, because the managers visited ships only occasionally, they were unlikely to have sound knowledge of the specific situations and work routines on their ships. Consequently, managers’ interventions for safety compliance were seen by crew members as failing to address real risk factors, and leading instead to increased workloads, psychological pressure and fatigue, the very antithesis of safety management. Meanwhile a coherent, supportive system for reducing risk remains underdeveloped in the shipping industry. JEL Codes: J81, J83, L91, M54, N75

History Of

This paper proposes a new concept of decision analysis based on a multiple criteria decision making (MCDM) process. This is achieved through the provision of a systematic and generic methodology for the implementation of design improvements based on experience of past failures. This is illustrated in the form of a case study identifying the changes made to Concorde after the 2000 accident. The proposed model uses the analytic hierarchy process (AHP) mathematical model as a backbone and integrates elements of a modified failure modes and effects analysis (FMEA). The AHP has proven to be an invaluable tool for decision support since it allows a fully documented and transparent decision to be made with full accountability. In addition, it facilitates the task of justifying improvement decisions. The paper is divided as follows: the first section presents an outline of the background to the Concorde accident and its history of related (non-catastrophic) malfunctions. The AHP methodology and its mathematical representation are then presented with the integrated FMEA applied to the Concorde accident. The case study arrives at the same conclusion as engineers working on Concorde after the accident: that the aircraft may fly again if the lining of the fuel tanks are modified.

For process safety management purposes, it is often required in industries to perform burst pressure calculations for pressurized equipment subjected to internal deflagrations. In predictions of burst pressures of vessels with short cylindrical shell sections, the stiffening effects of heads are often overlooked, which may lead to underestimated results. In this paper, a new improved method is proposed for predictions of burst pressures of thin cylindrical shells with small shell length to diameter ratios (L/D) at ambient temperature. The idea is to use the Svensson’s formula, modified by a factor that accounts for the effects of small L/D ratios, head types, and materials for more accurate predictions. Tables of such factors are developed based on study results from a series of elastic-plastic Finite Element Analyses including large displacement effect for different L/D ratios, thicknesses, materials, and head types. Some example problems are presented to validate the method.

The aim of the article is to address the socialization processes of modern children and adolescents, in the context of the characteristics of the information society and the constant presence of the Internet in their lives. A new but emerging phenomenon is emerging, video blogging, which is part of Internet socialization. The main characteristic of this phenomenon is the potential opportunity that children and adolescents have to create an independent video blogging process, which affects the socialization process in general. The empirical data were collected using quantitative and qualitative sociological methods: survey and interview with children. The combination of these methods provides more complete information to understand the problem. The main result of this study is the evidence that around 30% of children and adolescents are not only viewers of videoblogs, they not only consume the information disseminated by this part of the global network, but also become independent authors of videoblogs. The study results reflect the fact that many children's authors try to imitate their favorite video bloggers. Young Internet users perceive the process of creating a video blog as a certain type of creativity.

Abstract Background The urban water system is the worst hit in global climate change. Water resilience is the system’s ability to retaliate and recover from various water-related disruptions. The present study aims to delineate the water resilience zones in Chennai city, Tamil Nadu, India, by effectively integrating the geographic information system, remote sensing, and analytical hierarchy process (AHP). Methods The methodology incorporated 15 vital factors. A multi-criteria decision analysis technique was adopted to assign a weight to each parameter using the AHP. A pairwise decision matrix was constructed, parameter’s relative importance and the consistency ratio were established. Integration of all maps by weighted overlay analysis technique depicted water resilience intensities of five different classes. Results Very low, low and moderate water resilience areas accounted for more than three-fourth of the study area. Area Under Curve score (80.12%) depicted the accuracy of the developed model. Sensitivity analysis determined the significance of the parameters in the delineation. The logical structural approach can be employed in other parts of India or elsewhere with modifications. Conclusion This study is novel in its approach by holistically analyzing water resilience by integrating disruptions related to flood, drought and the city's water infrastructure system's adequacy and efficiency. Researchers and planners can effectively use the study results to ensure resilience as a new perspective on effective water resource management and climate change mitigation. It becomes a decision aid mechanism identifying where the system is vulnerable to potential water-related risks for employing resilience measures.
