Abstract
The article presents an analysis of the use of gas turbine engine in the propulsion and marine power plant of vessels, taking into account environmental aspects. The preliminary results of emission tests of harmful exhaust emissions of the laboratory gas turbine engine were presented. Also an analysis was also undertaken on the possibility of carrying out measurements of concentrations of pollutants in the marine gas turbine engine propulsion systems in terms of its operation on the vessel.

Energy requirements of maritime transport arising from their operational needs related to the function of the movement of the vessel and their existential functions has long been carried out by using mainly internal combustion piston engines.In the case of gas turbine engines, depending on the destination of the vessel and energy needs, power units and marine power plant with steam turbines are used in cases where nuclear power plants and systems with the so-called gas turbines in the form of gas turbine engines are used.As a result of smaller energy efficiency and the resulting higher fuel consumption, gas turbine engines for marine use are being replaced by piston engines and represent only a few percent share in the total population of marine internal combustion engines
The vessels power must take into account the weight but the mass of the entire engine propulsion unit, since the use of the gas turbine engine requires the use of additional reduction of gear rotational speed of the motor drive shaft to the desired speed of the vessel propulsion
Summary
Energy requirements of maritime transport arising from their operational needs related to the function of the movement of the vessel and their existential functions has long been carried out by using mainly internal combustion piston engines. Ever increasing emission of exhaust gases from marine engines implemented have necessitated the development of new construction concepts of marine power plant of civilian ships and warships It contemplates the use of gas turbine engines in marine power plant focused on the production of electricity used by electric motors vessel propulsions. The argument for the use of systems of turbine generators of electricity is the possibility to increase cargo space (Fig. 2) which improves the costeffectiveness ratio of vessel shipment, eliminating the lower overall efficiency of gas turbine engines It is especially the preferred solution of using light and alternative fuels such as natural gas, propane-butane, vegetable oil esters, methanol or ethanol. Environmental parameters requires a number of studies and analyzes, some of which are presented in this article
