Bearing Wear Monitoring System


XTS-W

Monitoring bearings’ conditions in real time for 2 stroke engine

Typical user HMI interface

XTS-W

(Initially developed by AMOT)


XTS2 is developed by AMOT first in the world in collaboration with MAN Diesel & Turbo. From its initial sea trials through to class, licensee and ship owner adoption, the XTS-W has evolved to become the leading bearing condition monitor on the market today. From 2017, the whole businesses for XTS-W are transferred not only sales but also manufactures to OK T&T

Principle of operation

  • Sensors fixed to engine frame measure position of guide shoes at Bottom Dead Center
  • Providing dater from any of the three crank train bearing 
  • XTSW2 shall be connected to alarm monitoring and safety system

A proven solution to maximise revenue and reduce costs

Avoid Open-Up Inspections 

MAN Diesel & Turbo has stated that if a system such as the XTS-W is installed, open-up inspections of all crank train bearings are no longer required, providing operational cost savings and removing the high risk of bearing damage during such inspections. Exposure of key personnel to potentially hazardous situations is also removed, offering a safer working environment. 

Cost-effective, planned maintenance

The XTS-W Bearing Condition Monitor provides ‘real-time’ data on crank train bearing condition. It displays the rate of degradation, bearing wear and the water-in-oil content to fully protect the crank train bearings. The XTS-W provides ‘real time’ information allowing the user to take appropriate corrective action, thus avoiding consequential damage, costly unplanned repairs and loss of revenue.

Maximum Availability

The XTS-W continually measures the condition of the bearing, offering an intuitive and reliable definitive monitoring device. Easily installed, the XTS-W is suitable for both new build installations and retrofitting to existing engines.

Proven Product

The XTS-W is Type Approved by major IACS and is a valuable component of the condition-based maintenance programmes provided by Classification Societies.

The XTS-W has many benefits

  • Avoids open-up inspections providing:
    -Operational cost savings
    - Removing high risk of damage during such inspections
    - Minimising crew exposure to potentially hazardous situations
  • Provides real-time information on bearing condition allowing effective operating decisions to be made maximum uptime, minimum cost
  • Monitors crank train bearings 24 hours a day, 7 days a week
  • Simple to install on both new build and existing vessels
  • Easy to use and comprehensive reporting
  • User-friendly home screen indicating both system and alarm status real-time
  • MAN Diesel &Turbo has reduced the frequency of external inspections if BCM is applied

Typical display screens

Home Screen - an intuitive overview indicating:- Bearing status
- System status, including component failure, malfunction or cable damage
- Any active alarms or slowdowns for BCM or WIO and SEDM if fitted

Bar Screen - indicating bearing wear:Sensor values
- Absolute wear values
- Deviation wear values
Cylinder values
- Absolute wear values
- Deviation wear values
- Alarm and slowdown thresholds

Trend Screen - indicating wear over a pre-specified time: - Historical access to identify when problems began
- Realtime, allowing rate of change to be monitored

Bar screen – indicating bearing temperature: - Deviation (top row)
- Temperature (lower row)
