Opis:: The concept of oil slick movement being influenced by wind and sea currents is elementary for the decision model of the distribution of large oil spill emergency control means at sea. The analysis of water area conditions such as wind and sea currents is elementary for the concept of oil slick movement. The article presents the model of oil slick movement under the influence of wind and sea currents. In building the model, random walk in two-dimensional lattice graphs has been used. The movement of oil slick is analysed in two ways. In the paper, the movement of the oil slick is analysed in two ways without wind and focus on surface sea currents and with wind and currents. Case one assumes no wind and focuses on surface sea currents only using random walk in a two-dimensional square grid graph. Case two assumes that wind is in place, so oil slick is moving due to surface sea currents and wind currents. The description of movement in case two is based on a two-dimensional lattice graph, which is a combination of a triangular grid graph and a hexagonal grid graph. The article also describes the basic assumptions of oil slick model: the definition of water area, oil slick and algorithm for rescue action to contain the oil spill. Oil slick movement concept is elementary for the decision model of oil spill control at sea. The model allows estimating the distance of oil slick from coastal areas.

Opis:: The petroleum substances (oil) spilled on the hard surface can be easily neutralized and collected by using powdery or granular sorbents. We are dealing with more difficult situation when oil spill appears on the soft ground or on the surface of the water. Extremely difficult is removing the oil from body of water polluted by dispersed one. In such cases useful are various balls, sleeves and mats filled by nonwovens. It is important to identify a material, which strongly absorbs different type of oil in a wide temperature range. At the same time, such material should have physical properties allowing easy and rapid contact with the spilled oil and then its removal from the environment. This paper provides an overview of impregnability of nonwoven fabrics made from two materials – polypropylene and cotton. The impregnability was tested against the water and the used lubricate oil. The tests were carried out by using experimental device constructed by members of the student’s scientific society at Faculty of Marine Engineering (Gdynia Maritime University). Principle of construction of testing device takes into account aspect of placing the sorbent in the package as well as possibility of repeating the experiment in precisely defined measurement conditions. Among tested materials, the best in terms of oil sorptivity proved to be polypropylene. The same material was the least absorbing water. It can therefore be assumed that this material is the most suitable for removing oil from the polluted water.

Opis:: Project analysis to meet needs for equipment customized to pumping out surface forms of oil in the port and other narrow basins are reported in this paper. New elements of the technical concept of the skimmer to eliminate the disadvantages of structurally similar devices are proposed - esential componets of the new type of skimmer currently elaborating in the Student Scientific Society „Nautica“ (at Faculty of Marine Engineering of the Gdynia Maritime University) are demostrated. The first motivation to this work is that the consequence of growing usage of ships in the world transport is necessity to search for more fast and efficient methods to remove oil pollutions from the water surface and the second one – preparation of appropriate training and research equipment for the continuous improvement of its construction as well as the manner of its use in variety conditions. Port areas are relatively small and they have numerous hard to navigate places, therefore oils which leaked from ships or transloading equipment are difficult to remove from the water surface. Those all factors promote the development of the new and innovative solutions for more efficient water treatment. New solutions of the technical concept of the skimmer are proposed here - among other the theoretically justifiable triangular inlet openings with the system of vertical positionnig relative to the water surface.
