Reliable Marine and Offshore Operations Begin with Clean Oil
Oil condition plays a decisive role in how systems perform under continuous load and harsh operating conditions
Protect Uptime and Reduce Maintenance Costs Across Marine and Offshore Equipment
In marine and offshore operations, oil is continuously exposed to saltwater, high temperatures, and mechanical stress. Over time, contamination from particles, oxidation, and water leads to wear, energy loss, and unplanned maintenance.
CJC® Offline Oil Filtration keeps oil clean and dry around the clock, even during shutdowns. By continuously removing particles, water, acidity, and degradation products, it extends the life of critical equipment, reduces operating costs and downtime, and supports more efficient, reliable operation.
The Real Cost of Contaminated Oil
Across fleets and offshore assets, reliability depends on the condition of the oil that keeps every system moving. Yet most operators still treat oil as a consumable rather than an asset. In reality, contamination quietly builds up over time, turning lubricants and hydraulic fluids into carriers of wear, corrosion, and inefficiency.
Unplanned downtime and off-hire
Unexpected shutdowns can cost thousands per hour in lost operation.
Rising maintenance costs
Contaminated oil increases wear on pumps, bearings, and valves, driving frequent repairs.
Reduced equipment lifetime
Microscopic particles act like abrasives, shortening the lifespan of critical components.
Higher environmental impact
Frequent oil changes increase waste handling, disposal, and CO₂ emissions.
Across commercial vessels and offshore units, the reliability of marine equipment depends on the condition of the oil circulating through engines, hydraulics, gearboxes, and auxiliary systems. Yet in many operations, oil is still treated as a consumable rather than a critical performance asset. In reality, contamination builds up continuously. Water ingress, combustion by-products, salt-related particles, and oxidation residues gradually turn lubricating and hydraulic oils into sources of wear, heat and instability that undermine efficiency and reliability at sea.

Oil Filtration That Keeps Marine and Offshore Operations Running
Offline filtration that removes water, particles, and oxidation residues to keep critical systems reliable and reduce unplanned downtime at sea.
Key operational benefits
Oil cleanliness better than new oil - Verified by ISO 4406 analysis on operating vessels.
Extended component life - Up to 4× longer service intervals in thrusters and hydraulics.
Stable operation and lower energy use - Cleaner oil reduces friction losses across systems.
Reduced oil consumption and waste handling
By keeping oil in stable condition for much longer, vessels can avoid unnecessary oil changes and significantly reduce waste-oil volumes. This lowers handling, storage and disposal requirements on board and supports more efficient, environmentally responsible operation.
Lower maintenance workload and fewer interventions
Continuous contamination control reduces the need for corrective maintenance linked to dirty oil, such as flushing, valve cleaning, and premature component replacement. This eases workload for crew and maintenance teams and helps keep planned maintenance schedules under control.
Improved reliability during critical operating periods
Clean, dry oil supports predictable performance during manoeuvring, dynamic positioning and high-load operation. By preventing contamination-related faults, oil filtration helps reduce the risk of off-hire incidents, delays, and operational disruptions at sea.
Applications across your vessel
Use Cases
“I was not surprised to see the effect of the oil filters. We are now installing similar filters across the sister vessel."
- Technical Inspector
Bourbon Offshore (Norway)
After installing a CJC® Fine Filter, soot levels fell quickly and the TBN value stabilised. The oil stayed within specification for more than 3,000 running hours instead of the usual 1,000, giving the crew longer and more predictable service intervals.
“This saves us money and is also better for the environment.”
- Senior Inspector
J. Lauritzen (Denmark)
Hydraulic failures on the deck cranes were causing delays and rising maintenance costs. With CJC® filtration keeping the oil clean and free from varnish, crane performance became stable and the fleet recorded only one breakdown in five years.
Water reduced from 35 percent to 0.06 percent.
Offshore supply vessel (Denmark)
With CJC® filtration maintaining clean lube oil and a stable TBN value, the main engine oil remained within specification for more than 3,000 running hours instead of the usual 1,000, giving the crew far greater confidence in their maintenance planning.

Sustainability for Marine and Offshore Operations
C.C.JENSEN filtration supports more sustainable marine and offshore operation by keeping oil clean for longer. When lubricants remain in good condition, fewer oil changes are needed, which reduces waste volumes, transport requirements, and the CO₂ impact linked to producing and disposing of new oil.
Why Choose C.C.JENSEN?
✓ High dirt-holding capacity designed for continuous marine operation
Built to handle long service intervals in engines, hydraulics, and auxiliary systems exposed to water ingress and fine contamination.
✓ Offline, non-intrusive filtration that operates without affecting vessel operation
Oil is cleaned continuously in a separate circuit, without influencing system pressure, flow, or critical manoeuvring and DP functions.
✓ Documented oil condition improvements verified through ISO cleanliness analysis
Performance is validated through regular oil sampling and trend analysis on operating vessels and offshore units.
✓ Effective removal of water and oil degradation products
Prevents corrosion, valve sticking, and thermal stress caused by moisture and oxidation residues in marine lubrication and hydraulic systems.
No obligation. We start with your oil condition and system data.
