Słowa kluczowe: LNG, risk assessment, logistic handling, sea terminal
Abstrakt: 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.

Słowa kluczowe: port, ship, manoeuvrability, navigational safety, approach channel
Abstrakt: 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.

Abstrakt: As an alternative to traditional fuel and energy source LNG (Liquefied Natural Gas) has many advantages, such as lower emissions while providing a means of energy for trucks, trains and ships. In focusing on the maritime transport sector the reasons for using LNG make a convincing business case, but lead to many discussions on LNG investments. The key issue has been is: “should investment be implemented first on LNG bunkering stations and then wait for the market to build ships to use the facilities or should investment wait until there is a demand?” Obviously, this creates a “chicken-and-egg” situation on when and where to invest for LNG use to take place. The initial experiences in using LNG in maritime and road transport suggest that the transport firms often take the risk themselves by not only investing into the transport units (ships, trucks) themselves but also invest into the infrastructure as well, e.g., developing LNG bunkering facilities. At the same time with these large initial investments for developing LNG bunkering networks there are more and more requests for identifying optimal solutions, often are based on real LNG fuel demand in ports and on the roads. This paper is oriented on the study for optimal bunkering network creation, which is argued to help with improved efficiency in the supply of LNG fuel to transport users. In addition, optimal investments for LNG bunkering networks can be realized.

Słowa kluczowe: LNG, LNG storage, LNG supply
Abstrakt: The increasing demand for Liquid Natural Gas (LNG) is causing many challenges for users and suppliers worldwide. Though there is strong interest in using LNG, the research published in this paper indicates there are challenges in developing adequate delivery and distribution chains within the supply chain. Ideally, LNG distribution chains should be created on the basis of user demands and need. In this paper we have articulated an optimisation model that considers the various potential users and their characteristics in order to identify if possibilities and prospects exist in developing an adequate LNG supply chain. The case study of Lithuania and Latvia serves as a model from which we are able to use our tool to help identify the factors for success in creating such LNG supply chains.

Tytuł: An international platform for cooperation on liquefied natural gas (LNG) – a report on the MarTech LNG project

Słowa kluczowe: clean energy, MarTech LNG, liquefied natural gas, Baltic Sea, LNG as a fuel, MARPOL, ECAs
Abstrakt: There were a number of circumstances which became the basis for the MarTech liquefied natural gas (LNG)
project: the forthcoming regulations reducing permitted sulphur content of a ship’s fuel, and aspirations of
Poland and Lithuania to diversify sources of natural gas import by building LNG import terminals. The project
was launched in 2012 and lasted more than three years until April 2015. It concerned the uses of LNG in the
South Baltic Sea region and was realized by eight partners from five countries surrounding this area. The main
aims were promotion of LNG as a fuel and dissemination of knowledge and experiences related to LNG. They
were achieved by organizing training courses, seminars and meetings between stakeholders, research institutions
and policy makers. This paper is an informal report of activities within the MarTech LNG project.
