The importance of liquefied natural gas (LNG) vessels and the technology that enables their operations is steadily growing. Hence, in addition to professional interest, the general public also displays a considerably large interest in this issue. Today LNG carriers belong to the category of the most technologically developed vessels and therefore managing these vessels requires not only the general knowledge but also the specific knowledge relating to their cargo handling systems. To ensure the safe and economical transport of LNG by sea and to minimize the risk of fire or explosion it is necessary to understand the properties of LNG and nitrogen, an inert gas used in all phases of the carriage and transfer of liquefied gas. The subject of this research is the overall process of nitrogen management in daily operations on board LNG carriers. The aim of the research is to explain, evaluate and define the various applications of nitrogen systems on LNG carriers.

Paper gathers information on Condition Assessment Programme (CAP), which is implemented by
classification societies to thoroughly assess condition of tankers and bulk carriers by inspection of
engine and hull. It is voluntary programme, mostly participated by tankers and bulk carriers which are
fifteen and more years old and today less present on the market. Special focus will be on ultrasonic
measurement of thickness of ship´s plates which is most significant indicator on condition of older
vessels. After all measuring is done, data is compared with classification society rules and condition
of hull and machinery will be assessed. This kind of inspection provides owners of older ships proof
that despite age their ships are equally capable of conducting sea voyage. The authors analyse the
number of ship arrivals in the port of Rijeka to gain a better insight into their age. Furthermore, the
authors advocate ultrasonic thickness measurement for the purpose of reducing hazards.

Croatia has well-indented coast and numerous islands and it is challenging to connect 48 permanently inhibited islands and at the same time respond to the requests of the population of the islands and their tourists in the maritime passenger transhipment. Although the liner passenger shipping has been established for series of years, it nevertheless requires a systematic approach to future development. Quite a number of scientific and technical papers have been written about the elements and the factors of the RO-RO liner passenger shipping significance. In this article authors examine the importance and role of the liner passenger shipping in connecting the islands with its mainland. This paper aims to evaluate the existing state of the port capacities for accommodating the RO-RO ships in order to modernize it and to emphasize the need for the improvement of the liner passenger shipping. Further in the paper, the maritime traffic of passengers and vehicles in the permanent line connection of the island and the mainland and the islands with each other in the Republic of Croatia. Particular attention has been paid to the level of development of the existing infrastructure for the accommodation of the RO-RO ships in the most significant Croatian ports. RO-RO passenger shipping is one of the key factors of the development of the Croatian islands. Authors point out the need to strengthen the role of the RO–RO passenger shipping as important part of maritime sector in the development and competitiveness of the Republic of Croatia through initiatives of sustainable growth of economic activities on islands and in the coastal area. The RO-RO passengers traffic simulations system would result in better insight into the possibilities for a more flexible connection of islands and mainland.
