There has been growing interest in fuel supply chains regarding transport safety and LNG reloading. This is due to the increasing consumption of this gas in the economy to create sustainable transport systems. Poland is in the phase of energy transformation, which increases the demand for this type of alternative fuel. For this reason, the number of logistic operations carried out by Polish sea terminals handling LNG deliveries is increasing. This article aims to present a method for assessing the risk of adverse events occurring during the logistic handling of LNG deliveries at a port terminal and its implementation for a selected LNG terminal in Poland. Fuzzy logic methodology was used to assess the risk due to the lack of access to specific historical data on identified events. The conducted analysis considers the guidelines applicable at the LNG terminal, described in the Terminal Operation Manual, and the specific reloading conditions occurring in the tested Polish gas terminal. Based on the analysis conducted in cooperation with experts, scenarios of possible adverse events were identified and subjected to a risk assessment. Based on the conducted analysis, those events were distinguished and their risk of occurrence.

An approach channel to the port is a very important part of port infrastructure ensuring navigational safety of the ships entering and departing the port. Various methods used for determining the width of the approach channel to the port provide different results. Sometimes, variations are significant and make difficulties in arriving at the correct final decision. The article analyses diverse methods for research on calculating the width of the approach channel to the port. The obtained results have been verified conducting a real experiment involving real ships passing under similar hydro-meteorological conditions. The evaluation of the results and recommendations presented in the article can be used for the optimization and design of approach channels to ports
