ENVIRONMENTAL POLLUTION CAUSED BY MECHANICAL SYSTEM FAILURE ON SHIPS

Sa？etak Abstract Ships and other types of vessels contain very large quantities of lubricants in their structural assemblies used for steering or motion. This lubricant serves to reduce friction between the parts and prevents their wear and tear. Due to increasingly demanding criteria related to environmental pollution, changes are implemented in design solutions regarding new lubrication methods which are less harmfull to the environment in case they come into contact with the environment. New design solutions apply new types of lubricants, which have different chemical structures, the tribological properties of interacting materials likewise change, so we need to use new construction materials that provide good mechanical tribological properties for a structural system with regard to its motion and steering. New types of lubricants, as well as new construction materials, are quite underresearched. This complicates their use in realistic systems. The aim of this paper is to provide an overview of new solutions with regard to lubricants and construction materials, as well as estimating their adverse impact on the environment
