Abstract

This paper presents possible ways of identifying the operating states of naval gas turbines by the Base Diagnostic System (BDS) application. The system configuration, testing means and methods are demonstrated in this paper, whilst the application of methods of vibroacoustic analysis in naval technology is also discussed. BDS is used in ships that are powered by the COGAG power plant. This paper examines the permissible in-service imbalance and appropriate assembly of turbine rotors on the basis of selected vibroacoustic parameters, as well as the determination of their permissible operation time resources. Another element of BDS that will be analysed in this paper is the vibration control of misaligned propulsion shafts. Keywords: marine gas turbine, technical diagnostics, diagnostic system, testing means and methods, diagnostic software, risk analysis. 1 Introduction As a result of developments brought on by technical advances, there is a great demand for highly specialized services that meet the requirements of the complex technology that is currently on board ships. In this paper we present the diagnostic systems that have been created to support the exploitation of the vessel power plant with gas turbines. Contemporary ships are complex constructions with enormous power levels reaching 100 MW. Due to navigational and environmental concerns, as well as safety and protection of human life and property, these ships require highly qualified crews in order to operate. As a consequence, the necessary educational standards for future ship captains as well as engine room officers, who are responsible for operating the ship’s equipment, are constantly increased. The requirements set by maritime organizations (IMO) indicate the great importance of practical classes and
