NORDEN Bearing Monitoring & Water Filtration System 

  • Environmentally friendly - pure seawater as lubricant
  • A steady flow of abrasive free seawater to bearings
  • Built in redundancy
  • Flow monitoring & Alarm
  • Wear monitoring and logging, enabling condition based maintenance 

Description
Norden Bearing Monitoring & Water Filtration System is designed to support our stern tube bearings. The open loop system collects seawater from vessels sea chest. The filtration unit remove particles causing wear on bearing, shaft and liner. The water is pumped into the stern tube and lubricate the stern tube bearings, enabling hydrodynamic running of the shaft. The open loop design eliminates need for an aft seal, as the seawater is flushed back to the sea.

The safe operation and condition of the bearing and water supply is continuously monitored by the control and monitoring system. Real time system status is available on the control screen, together with alarm log and bearing wear trend. The trending of bearing wear enable condition based maintenance planning, saving cost and time for the operator.
