The article presents the results of analysis of improvement possibilities of lubricating properties by the modification of lubricants with the use of functional additives that improve resistance to the wear and scuffing of frictional couple. The research encompasses different base oils. Mineral oil and the synthetic oils, i.e. ester oil and hydrocarbon oil, were investigated. Tribological investigations were conducted with the use of a four ball apparatus. The research results were analysed with particular consideration of simultaneous effects of two types of additives, i.e. anti-wear and anti-scuffing. As the result of research, the possibilities of forming a lubricant’s anti-wear and anti-scuffing properties have been demonstrated through the selection of the percentage of additives. The limitation of simultaneous improvement of both resistance to wear and scuffing was also demonstrated. This limitation is due to the additives’ interactions.

Storage of recovered oil and oily water is an important issue when it comes to maritime disasters, being a significant factor of the overall operation. Using large storage vessels is not always an option especially when the vessel is close to the shore. Currently, floating or non-inflatable tanks made of composite textile materials are used worldwide for the storage of the water/hydrocarbon mixture, regardless of the area of action (maritime or fluvial). The research carried out so far by INCDTP specialists, which consists in modelling, simulation and numerical analysis of various constructive forms and devices, led to the conclusion that for the making of a floating tank for storing water/hydrocarbon/oil mixtures, the best solution for its construction is represented by textile materials woven from high-tech yarns (p-aramid and polyamide 6.6) covered with polyurethane. The experimental model of the floating tank for the transport of oils and hydrocarbons in case of disaster was designed by INCDTP specialists and consists of five experimental models of floating materials (made of five variants of covered textile structures) and assembled in collaboration with specialists from SC CONDOR SA, in the form of a floating storage tank. The storage tank that has been created will be tested on the ground first, in order to perform all gravimetric and quality measurements
