The Replacement of the Gas Turbine in Case of a Marine Vessel Revitalization

Propulsion groups based on gas turbines are subassemblies that must be replaced in the case of the revitalization of a ship of a certain age. Due to the consumption of the vital resource of the ship's old gas turbines, they must be replaced with new turbines that have the same power, but greater efficiency due to the new manufacturing concept. The paper presents the case of replacing an old generation turbine with a modern turbine used in aviation but adapted for marine use. The new turbine together with the related automation was first tested on the stand and then was integrated on the ship instead of the old one. The tests carried out confirmed the fairness of the chosen solution, the power parameters being those expected. In tests the power and consumption of the new propulsion line were compared with the old propulsion line, the results showing a power developed equal to lower fuel consumption.
