Open-up inspections can now be avoided if an Amot XTS-W+ bearing condition monitor is installed.
The XTS-W+ is the first bearing wear monitor to gain approval from MAN Diesel & Turbo and Germanischer Lloyd (GL) after completion of extensive trials on the Hapag-Lloyd vessel Hanover Express. The approval will allow ship owners to apply for survey arrangement condition monitoring (SACM) if an XTS-W+ is installed and there is the reassurance that the bearings are in good condition.
Eliminating unnecessary open-up inspections of the crank-train bearings represents huge operating cost savings since such inspections are a major cause of premature bearing failure, resulting from miss-assembly, ingress of dirt or even physical damage. Because of this MAN does not recommend unnecessary opening up of the crank train bearings on its 2-stroke low speed engines.
The XTS-W+ has significant operating features including an additional bearing damage algorithm that quickly indicates short term changes, fully automatic calibration and fully integrated water-in-oil (WIO) and shaft line earth monitoring (SLEM). Such features enhance the proven real-time monitoring of diesel engine crank train bearings, providing early warning of bearing wear, preventing high cost consequential damage and unplanned downtime.
According to GL, open-up inspections can be omitted providing an approved bearing wear monitor, water in oil monitor and shaft line earth monitor are fitted.
