Bearing condition monitoring device
Recently fully approved by Germanischer Lloyd, ship owners can now apply for GL Survey Arrangement Condition Monitoring (SACM) if an XTS-W is installed.
The XTS-W uses custom proximity sensors to measure the relative position of each guide shoe, at Bottom Dead Centre (BDC), with respect to the crankcase. Any significant wear in the bearing surfaces results in a shift in this measurement, thus facilitating early detection of a failure. This measurement technique is used to detect wear in the main, crank-pin and crosshead bearings.
