Abstract: 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.

Abstract: 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.

Abstract: 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.

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

Abstract: 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.
