CJC ThrusterFilter

Remove Water From Thruster System Oil

Water in thruster gear oil systems is a serious problem costing offshore vessel owners thousands of dollars every year for thruster repairs, oil changes, down time, and dockings.

According to an IMCA survey thruster malfunctions accounted for 15% of all lost positions from 1991-94 (not including computer and electrical failures).   Another 1993 survey proved that azimuth thrusters failed an average of 7.65 times per year and tunnel thrusters failed an average of 2.80 times per year.  Water in the gear and hydraulic oil account for the majority of thruster break-downs.

The water is mostly entering the systems through the thruster main seal and although there has been an impressive effort made to develop a means to prevent this form occurring, it has not been enough to overcome the water ingression problem.   Therefore, it is imperative to consider the means of separating and removing the water from the system oil.

C.C.JENSEN A/S has developed a special CJC™ FilterSeparator for keeping thruster systems water free.  The CJC FilterSeparator is operated offline - circulating the oil continuously with it own pump.  The unit is fitted with electrical oil preheaters for optimizing water separation from the oil and a fine depth filter retaining solid particles down to 0.8 micron in size.

Many offshore vessel operators world-wide vouch for the performance of the CJC ThrusterFilter...they have experienced reduced maintenance costs after only 6 months operation with the CJC ThrusterFilter
