F’IS monitors bearings on Germany’s largest luxury liner
Herzogenrath, August 10, 2009. Innovative bearing technology of the Schaeffler Group and latest monitoring equipment of FAG Industrial Services (F'IS) ensure a good journey on the 315 meter long cruise liner Celebrity Solstice.
Right from the start the requirements on the largest cruise liner ever been built in Germany were high. Besides luxury and comfort, safety and speed were two important points, to which especially the propulsion and steering systems contributed. The ship was equipped with two so called Azipod® propulsions produced by ABB Marine. These are capsulated propulsion units which are located outside the hull. The innovative propulsions, each equipped with two spherical thrust roller bearings and one radial spherical roller bearing from FAG, ensure that the luxury liner maneuvers safely and is able to accelerate to a speed of 24 knots (about 45 km/h). The bearings in the propulsion are exposed to high loads absorbing thrust forces and loads from the engine and the propeller. Facing this background a high availability of these important ship components is essential. This is accomplished by permanent condition monitoring. Therefore, each Azipod® propulsion unit is equipped with an ABB Propulsion Condition Monitoring System (PCMS) operating with an online condition monitoring system FAG DTECT X1.
First measurements with the online monitoring systems were done during the test run of the cruise liner prior to the official commission. The systems performed as expected. Additionally, F'IS performed endoscopy measurements before the official startup to inspect the bearing raceways and bearing housings regarding contamination. With this inspection F'IS could also verify the sound condition and correct mounting of the bearings.
Since the maiden trip of the Celebrity Solstice at the end of 2008 the PCMS and FAG DTECT X1 systems monitor the bearings on a permanent basis. Based on a service contract between ABB Marine and F’IS all recorded vibration data is sent to the F'IS Diagnosis Center in Herzogenrath (Germany). There the data is analyzed by experienced vibration experts. In case of irregularities or on request ABB gets a detailed report about the bearing’s condition.
With the aid of the vibration analysis the information received helps to detect the bearing wear and possible emerging bearing damages at an early stage. This ensures that in case of abnormal changes in bearings the shipowner can react in good time and plan the ship overhauling schedules in the most convenient way.
