    In connection with the current investment project of building an liquefied natural gas (LNG) terminal in Świnoujście, an analysis of design solutions and operational features of the potential variant of an LNG carrier supplying gas from the Persian Gulf areas has been conducted. As a result of studying the waterway restrictions on the assumed route, the article presents the concept of the optimum LNG carrier size – its overall dimensions – along with an analysis of design parameters. A hull shape model was used to examine the hull resistance and propulsion system. Besides, the size of the ship engine room was estimated and the power demand of the main propulsion system was determined. The cost patterns of LNG carrier construction and operation was included as well as the estimated mean value of its construction unit cost

    In the last years, in the area of mining polymetallic nodules has been made a lot of progress in their search, assessment of the marine environment, the development of mining technology, was developed a framework for political and legal and made economic analysis. Therefore, is increasingly becoming a feasible mining of Fe-Mn on an industrial scale. One of the basic elements of the whole system of mining is mining ship, hence the article presents a scheme the determination of its size depending on the initial parameters, i.e.: the annual efficiency of mining and storage period of excavated material in the holds of the ship. Determined dependence of regression to the preliminary forecasting ship size by using the information from drill ships – deemed similar in terms of functional and architectural. As a result of analyzing the main compartments of the vessel was estimated the percentage of volume in the hull of the vessel. Performed visualization of spatial design concept of mining ship.

    The economic crisis initiated in 2007, has caused disturbance and a fairly a sharp drop the yachting industry in the country. Many of foreign companies could not bear at all the crisis and were forced to close or were absorbed by other companies in the sector. Since 2010, is observed the at first slow, and currently the dynamic growth of produced boats for various purposes also on the Polish market for Polish customers. The upward trend of the sector will need adequately trained engineers (specialists) - designers, constructors, technologists, etc. Deficiencies literature regarding (approaches) design guidelines on recreational boats, bowed the author to develop one of the methods determine the basic dimensional parameters and design of motor yachts at the initial stage, right away selected the technical assumptions. Based on the gathered database of built yachts developed regression that allow the initial design stage to determine the basic dimensions, namely: LOA, B, H, T and the design parameters, i.e. D, SP, CB yacht. This allows start the next project stage, which is the creation the first concept yacht along with his shape, bodylines and estimate construction costs.

    In a mining ship, the tracking control system is one of its most significant systems. Its power output depends on weather parameters in the mining area and on dimensions of the ship. The tracking control system power is very high, thus the dimensions of the ship are considerably influenced by the weight and dimensions of the ship power plant. The article presents a spatial conception of a mining ship and the determined maximum power demand of the tracking control system. This article is a continuation of the prob-lem described in [2].
