LNG Carrier Main Steam Turbine Reliability in the Exploatation Period of Time

Abstract

In this paper the LNG carrier with steam turbine propulsion plant maintenance records has been analysed. Actual observed data from the ship, built in 2001, are from ship maintenance history data from September 2002 until August 2010. During the analysed period, main propulsion turbine had one major failure and several minor failures. The ship had three dry docks and one was prolonged due to increased requirements for cargo transport. Total running hours of the main propulsion turbine in the observed period of time were 63204 hours. The list of failures and influence of each mentioned failure of main turbine propulsion machinery is discussed and analysed in respect to the propulsion autonomy of the vessel.
