Seadrill Norway, west venture

Please see how Seadrill Norway benefited by installing CJC® Filter Separators at their 8 Rolls Royce Thrusters and CJC® Fine Filters at their 2 Rig Cranes as part of a preventive oil maintenance program:

System
8 Rolls Royce Thrusters.
Oil type: Shell Omala 150

Problem
Two of the thrusters suffered from heavy water ingress - water content was measured to about 2,000 ppm.

Solution
As part of a preventive oil maintenance programme two CJC® PTU2 27/27 PV Filter Separators with CJC® Filter Inserts BLAT 27/27 were installed at the Rolls Royce Thrusters. The demand for keeping particle and water contents at low levels very soon led to the installation of further filter separators on the remaining six thrusters.
In addition to this, two CJC® Fine Filters HDU 27/27 P with CJC® Filter Inserts B 27/27 were installed on the rig cranes.

Result
Already after a short period of filter separator operation, the oil cleanliness had improved considerably.
The average water content in the thruster oils is now maintained within a range from 400 to 600 ppm.

CUSTOMER STATEMENT

Mr. Jan Egil Sandnes and Mr. PeterJørgensen, Technical Managers on board the “West Venture”, state that they are very satisfied with the installations of CJC® Filters on both cranes and thrusters.
