New international regulations aimed at decarbonizing maritime transportation are positively contributing to attention being paid to the use of liquefied natural gas (LNG) as a ship fuel. Scaling up LNG-fueled ships is highly dependent on safe bunkering operations, particularly during simultaneous operations (SIMOPs); therefore, performing a quantitative risk assessment (QRA) is either mandated or highly recommended, and a dynamic quantitative risk assessment (DQRA) has been developed to make up for the deficiencies of the traditional QRA. The QRA and DQRA are both data-driven processes, and so far, the data of occurrence rates (ORs) of basic events (BEs) in LNG bunkering SIMOPs are unavailable. To fill this gap, this study identified a total of 41 BEs and employed the online questionnaire method, the fuzzy set theory, and the Onisawa function to the investigation of the fuzzy ORs for the identified BEs. Purposive sampling was applied when selecting experts in the process of online data collection. The closed-ended structured questionnaire garnered responses from 137 experts from the industry and academia. The questionnaire, the raw data and obtained ORs, and the process of data analysis are presented in this data descriptor. The obtained data can be used directly in QRAs and DQRAs. This dataset is first of its kind and could be expanded further for research in the field of risk assessment of LNG bunkering.

Recent projections from marine transportation experts highlight an uptick in maritime traffic, attributed to the fourth industrial revolution’s technological strides and global economic rebound. This trend underscores the need for enhanced systems for maritime accident prediction and traffic management. In this study, to analyze the flow of maritime traffic macroscopically, spatiality and continuity reflecting the output of ships are considered. The course–speed (CS) model used in this study involved analyzing COG, ROT, speed, and acceleration, which can be obtained from the ship’s AIS data, and calculating the deviation from the standard plan. In addition, spatiality and continuity were quantitatively analyzed to evaluate the smoothness of maritime traffic flow. A notable finding is that, in the target sea area, the outbound and inbound CS indices are measured at 0.7613 and 0.7501, suggesting that the outbound ship flows are more affected than inbound ship flows to the liquidity of maritime traffic flow. Using the CS model, a detailed quantitative evaluation of the spatiality and continuity of maritime traffic is presented. This approach facilitates robust comparisons over diverse scales and periods. Moreover, the research advances our understanding of factors dictating maritime traffic flow based on ship attributes. The study insights can catalyze the development of a novel index for maritime traffic management, enhancing safety and efficiency.

“…In the study, the frequencies of the risks caused by local traffic in the region were determined by applying three different models. Yücel and Yurtören (2019) used the ES Model and the fuzzy logic model together to determine the risk factors and their weight in port manoeuvres. Until then, the risk factors and the weights of these factors have not been known in the studies about "ES Model".…”

Ports are the connection points between the sea and the land in the maritime industry, have an important role in world trade. Ports host many ships each day. The characteristics of the ships that can manoeuvre within the port limits are determined depending on the technical structure of the ports and the environmental conditions of the ports' location. The characteristics of the ships such as their type, length, width, draft, and tonnage are important factors that determine the port's limitations. If these restrictions are not followed, it is inevitable for marine accidents to happen within the port area, which can lead to severe consequences such as deaths and injuries, material damage, environmental pollution, and even disasters. Risk analysis studies are carried out in order to prevent possible accidents at the ports and to determine the perils that may occur. When the studies in this field are examined, it is determined that different risk analysis methods are utilized. By using these analysis methods, the dangers sourced from ship manoeuvring that may occur within the port limits are tried to be analysed. The purpose of this study is to create a risk analysis model to be used in the ship manoeuvres and to determine which ships are suitable for manoeuvring in a port and under which environmental conditions ship can manoeuvre. Fuzzy Fine-Kinney method was chosen as the main risk analysis methodology for this study, which has not been used in the related literature. In the study, a full mission ship's bridge simulator was used in created scenarios by taking various environmental conditions into account and coming alongside manoeuvres were carried out by masters with a pre-determined ship on a pier at a port in Istanbul. After the end of each manoeuvre, surveys were filled out and assessments were made by masters that are considered experts in the maritime domain. According to results obtained from the risk analysis method applied in the study, it was determined which ships with which characteristics are suitable for manoeuvring and under which environmental conditions.
