Refrigeration systems of fishing vessels have a similar impact on the natural
environment as refrigeration devices applied in remaining economy sectors. Adopting a principle of estimating equipment costs in the entire operation period, it must be stated that environment impact appears in all installation lifetime stages, from its elements production moment, through assembly, startup, operation, repairs, shutdown and liquidation. Fundamental elements of the environmental impact are impoverishing
ozone layer in the ionosphere, gas emission, smog production in the lowest atmospheric layers, soil and waters acidity change as well as natural water reservoirs eutrophication. As a result of international actions the refrigeration industry tries to limit its harmful impact on natural environment by introduction of new refrigerant and design solutions of refrigeration installations. An integrated approach to the issue includes:

  • installation design choice and refrigerant selection;
  • procedures choice, responsible for safe refrigerant operation;
  • introduction of technology reducing leaks and increasing installation efficiency;
  • promotion of the latest knowledge and staff training, responsible for designing and
  • operation;
  • predicting and estimating possible refrigeration systems elements failures for prevention and repair purposes. These issues remain in the interest of centers responsible for implementation of environment-friendly solutions in the refrigeration. The paper presents the correlation analysis of failures occurred in the refrigeration systems of Polish fishing vessels in 2007-2011 years. Analysis results described in the paper can be a base to draw up guidelines, both for designers as well as operators of the marine refrigeration systems to avoid the harmful impact on ozone layer and natural environment.
