rigs & drillships – hydraulic systems

Rigs and drill-ships are equipped with HPU’s, BOB and riser tensioner systems, top drives, draw works, cranes, mud pumps, turbines and mooring winches. These hydraulic system and the HPU, supply power to equipment such as top drives, mud pumps and iron rough neck drilling motor. This equipment is a key part of the production on a rig or drillship, and they must work at all time to achieve a high and effective production. 

The hydraulic oil will be contaminated with particles, water and oxidation residues from the day-to-day operation, and if the oil is not clean and dry, then the risk of failing systems is eminent, and the risk of drilling halt increases. The hydraulic oil in the system will be contaminated with particles, condensation water and oxidation residues, which could lead to malfunctioning valves, and pumps. You can experience sticking valves caused by oxidation residues, and then it will not function perfectly. Eventually, this can lead to higher maintenance costs and ultimately to loss of drilling operation. Existing in-line filters do not remove oxidation residues. 

Benefits, installing CJC® Oil Filters

  • Protect your investment – keep the drilling operation going
  • Optimise efficiency of the rig or drillship
  • Reduce risk of costly hydraulic repairs
  • Reduce risk of unplanned breakdowns and lost production
  • Reduced maintenance costs

When you install a CJC® Oil Filter solution on your hydraulic system, you ensure that they do not break down. You get an oil filter with excellent dirt, water and oxidation removal capacities, and the highest dirt holding capacity, and this gives you cost savings and better reliability of the hydraulic systems, and a high efficiency of your rig or drillship. 

Technically, CJC® is known for keeping oil clean, dry and without oxidation residues, which is documented over many years and in several offshore installations. CJC® Oil Filter solutions are installed on many offshore rigs and drill-ships. 

When you choose CJC® Oil Filters, you ensure a long lifetime of the hydraulic systems, reduce maintenance and you avoid unplanned breakdowns. You can even monitor the condition of your system using the Oil Contamination Monitor.

Your solutions
For hydraulic system on drilling rigs and ships, you can select between below solutions:

  • CJC® Fine Filter, HDU
  • CJC® Filter Separator, PTU 
  • with or without CJC® Oil Condition Monitor, OCM15

The CJC® System solutions fit all sizes of hydraulic systems, and we deliver globally where required. In close co-operation with technical organizations, we help select the most fitting solution depending on system type and conditions in the environment.
