Oil Filtration
Oil filtration and decontamination
Before deciding to replace an oil, the condition of the fluid and the equipment should be assessed. In technical partnership with WCL, RS assesses the feasibility of filtering and decontaminating lubricating, hydraulic and insulating oils in marine, port and industrial applications.

Why engage RS
The decision starts with technical feasibility.
Treatment has to make sense for the type of fluid, its condition and the application. A technical assessment shows when filtration and decontamination can be considered, without treating recovery as an automatic answer for every situation.
- 01
Assess before replacing.
The condition of the oil and the equipment guides the analysis of treatment as an alternative.
- 02
Consider the application.
Lubricating, hydraulic and insulating oils call for an assessment suited to the system they serve.
- 03
Decide on clear criteria.
Feasibility guides the service and the review of possible benefits, within the agreed scope.
Service scope
Oil Filtration & Specialized Services
Treatment of lubricating, hydraulic and insulating oils for vessels, terminals and industry, in technical partnership with WCL.
Fluids covered
Lubricating, hydraulic and insulating oils, assessed according to the system they serve.
- Filtration and decontamination of lubricating oils
- Filtration and decontamination of hydraulic oils
- Filtration and decontamination of insulating oils
Applications and feasibility
Where the service applies and how feasibility is assessed before treatment.
- Applications on vessels, tugs and other craft
- Applications at port terminals and industrial plants
- Feasibility assessment: fluid, equipment and technical parameters
Specialized services
A separate RS service line, independent of filtration: special technical inspections and coordination of specialized services.
- Special technical inspections of vessels, equipment and facilities
- Nationwide coordination of specialized technical services
When RS is called in
Contaminated fluid
Water, varnish and solid particles in oil are associated with wear and component failure. The assessment shows whether treatment is an option for the fluid in service.
Hydraulic and auxiliary systems
Pumps, valves, bearings and hydraulic systems depend on fluid condition. Where feasible, treatment supports the maintenance of these systems.
Less disposal, where feasible
Where treatment is technically feasible, recovering oil can reduce the volume of used oil sent for disposal or re-refining.
How RS works
Assessing condition to define treatment
- 01
Understanding the application
Oil type, equipment, location and reason for the assessment shape the request.
- 02
Examining feasibility
The available information and applicable technical parameters help assess whether treatment is possible.
- 03
Defining the service
The approach and treatment are agreed based on the assessment and the scope.
- 04
Carrying it out where indicated
Filtration and decontamination are performed where technically feasible and contracted.
What the client receives
Any benefits depend on the technical feasibility of each case.
- Assessment of fluid and equipment conditionSupport in understanding the request.
- Feasibility opinionGuidance for deciding on the treatment assessed.
- Filtration and decontamination where indicatedCarried out according to the agreed service.
- Maintenance supportInformation related to the request to support asset management.
Common questions
Can every oil be recovered?
Feasibility depends on the type and condition of the fluid, the equipment and the technical parameters of the application. The assessment shows whether treatment is a suitable alternative.
Is the service limited to vessels?
RS also lists applications at port terminals and industrial plants, as well as vessels, tugs and other craft. Attendance depends on the assessment of the request.
