Announcement for Mitsubishi Condensing Type Steam Turbines

This announcement is prepared for a general proposal to the users of condensing type steam turbines supplied by Mitsubishi Heavy Industries Compressor Corporation ( MCO ) to ensure safe, uninterrupted and productive operations in long term.

Mitsubishi Heavy Industries Compressor Corporation ( MCO ) and Maintenance Partners Belgium, a group member of Mitsubishi Heavy Industries LTD, have recently received Mitsubishi steam turbine rotors on a row with damages on the  rotor disc blade grooves, caused by Stress Corrosion Cracking. ( SCC )

All received rotors had more than 100.000 running hours and / or over 400 times starts and stops. To avoid catastrophic faillures, unexpected plant shut downs and long period for recovery, MCO and Maintenance Partners Belgium could submit you an offer to perform a full life time assessment inspection on your Mitsubishi Condensing Type Steam Turbine rotor and casing. This inspection could take place on site or in our workshop in Zwijndrecht, Belgium.

Enclosed you will find a photo report of a refurbished damaged Mitsubishi Condensing Type Steam Turbinee rotor caused by SCC. Technical bulletin life time assessment inspection for steam turbines including several reliability improvements for steam turbines and centrifugal compressors to ensure safe, interrupted and productive operations for Mitsubishi steam turbines and centrifugal compressors as well for NON Mitsubishi steam turbines and centrifugal compressors, like earth strap for rotor grounding, dry gas seals and Sermalon coating application.

If you are interested in receiving a proposal for above mentioned subject or any other enclosed reliability improvements please do not hesitate to contact us by phone (tel: 0032(0)3 744 1501) or e-mail
