    Defects such as Crack, Penetration, Leakage, Worn Out, Blow Off,
    Impact, Out of Tolerance etc. are carefully recorded after component being inspected in our premises.
    By judging according to inspection result, scope of work will be specified then.
    When defects are inspected far too much or seriously damaged, it will be classified into FULL RECONDITION category.
    It means its work extent and procedure will consume more time and material as well.

    For instance, a piece of cylinder cover of Sulzer engine RTA type
    was detected by Ultrasonic Test (UT) cracks seriously penetrated to the bottom around cooling water bores,
    then according to Maker’s Specification, it will be proposed to proceed FULL RECONDITION to the ship owner.
    The combustion surface will be completely machined out till bottom of all cooling water bores .
    Then rebuild up by welding and precision machining in conformance with drawing.

  • PARTIAL RECONDITION
