Flushing units are housed in easily transported ISO containers

Benefits of the service

• Increased equipment life - Regular flushing of the system significantly reduces the potential for system failure due to

oil contamination, as old oil and residues left in the lines and system, as the reservoir is drained, cannot be easily re

moved in another way.

• Reduced expensive downtime - Using one of our high performance flushing units and trained technician is quick and

efficient, helping to minimise downtime.

• Optimised maintenance intervals - Regular oil sampling and analysis provides an effective, preventive maintenance

programme.

• Reduced maintenance costs & improved productivity - The cost of new oil is saved as it can be recovered, filtered

and reused after flushing. Clean oil ensures consistent machine performance with reduced down time.

• Consistent quality and safety - All units are equipped with inline laser particle counters & oil sampling, and have level/

pressure monitoring with automatic shutdown on adjustable set values.

Reduce expensive hydraulic system downtime

As the cost of sophisticated, high pressure

systems continues to rise, proactive

maintenance is imperative to maximise the

system service life and minimise operating

costs.

The single most important preventive

maintenance procedure is regular oil sampling

and analysis. Over 96% of all hydraulic failures

can be traced directly to oil that has been

improperly cared for. As long as the oil has

not lost viscosity and has not been damaged

by overheating, it can normally be reused by

flushing the system.

When the oil is just drained from the reservoir

and the system replenished, several gallons

of old oil and residues are left in the lines and

components. As new clean oil is introduced,

it mixes with the old oil, absorbing the

contaminants, circulating them through the

system again to cause further damage.

Flushing the system is the only way to remove

these potentially damaging residues as part

of the maintenance regime.

At Rolls-Royce, we recommend the following

process to reduce expensive downtime:

1. Clean the hydraulic system properly

2. Keep the system clean

3. Monitor the hydraulic fluid

4. Maintaining cleanliness levels

Self contained high performance flushing units are available for deployment worldwide

together with a trained technician.

As a doctor can see signs of illness in a

patient by analysis of body fluids, a trained

hydraulic technician can find signs of

component wear by oil analysis

All flushing system units are based on ISO containers and are designed to

operate virtually anywhere. Strategically located at hubs around the world,

we aim to service our customers globally by working around your vessel’s

schedule.

Complex onboard hydraulic systems must have clean oil to be reliable. The small cost of flushing the system far outweighs the cost of an expensive system failure and the associated downtime.

Keeping your hydraulic system clean

1. Flushing cleans the system properly

As the cost of sophisticated, high pressure systems continues to rise, proactive maintenance

is imperative to maximise the system service life and minimise operating costs.

Always flush a new or a rebuilt hydraulic system, filter the oil up to the required NAS level or

ISO code. Rolls-Royce provides this service and will inspect and verify that the system, the

hydraulic piping, storage tanks and filling routines meet the required standards. Our flushing

units are hired out with a trained technician, as no matter how good the machine, it is only

as good as the man operating it. We provide a full flushing report and plus documention to

customer specification.

2. Keeping your system clean

Once the system has been fully flushed, always fill the tank with oil, filtered to the manufacturer’s

standards. New equipment, hoses, pipework must never be installed without checking they

have been properly cleaned.

4. Maintaining cleanliness levels

Do you know what standard of system cleanliness you have? A trained Rolls-Royce technician

can find signs of component wear through oil analysis. The investment in a proactive

approach will quickly be recovered through improved performance and reduced operating
