Agenda:
• Types of lubricants
• Advantages and disadvantages
• How to apply and maintain
• US environmental protection agency
• Best practice
• Case study in the Netherlands
• CJC oil conditioning systems

2. Types of bio-lubes
Natural, synthetics and blends such as:
• PAO (Polyalfaolefins)  low temp properties
• Di-esters  good anti-oxidation characteristics
• PAG (Polyalkyleneglycols)  fire resistant
Note: Bio based property at least 51% of the lubricants is made of
natural biomaterials.

Advantages and disadvantages:
 Good lubricating qualities  polar nature
 Good solvents  keep dirt and debris in suspension
 High natural viscosity and viscosity index
 Higher flash point then mineral oils
 Biodegradable and less toxic
o Shrink rubber seals
o Poor solubility with additives
o Emulsifies with water  high saturation level
o Low oxidative stability
o Higher pour point

4. How to apply and maintain:
 Consider the lube system design characteristics such as
operating temperature, pressures and flow rates.
 Flush the system when switch from mineral to bio-lube,
incomplete conversion leads to severe foaming, plugged
filters, higher wear on components, increased operating
temperature.
 Correct sealing and hose materials.
 Cross contaminations with other fluids during assembly, check
whether the fluids are compatible.
 Oil conditioning unit to maintain the required cleanliness to
ensures the quality of the lubricants

5. US Environmental Protection Agency
From 19 December 2013 ships sailing into US waters to use EAL
(Environmental Acceptable Lubricants) in all oil-to-sea interfaces
unless technically infeasible.
Most relevant components are:
o Stern tubes
o Rudder bearings
o Controllable Pitch Propellers
o Thrusters
o Fin stabilizer

7. Best practice:
• Tank design and seals
• Oil type selection
• Configuration of shut-off valves, pressure relief and non
return valves to minimize cavitation and shearing.
• Tank breathers (silica gel)
• Regular oil samples intervals and trend analysis
• Adequate oil cooling system, recommended operating
temperature 50-60°C
• Oil condition monitoring device ea. moisture, ISO4406
cleanliness code, temperatures, pressure, etc.
• Oil conditioning unit in off-line (side stream) configuration,
keep the oil clean & dry in optimum quality

18. Summaries of case study:
• Pre-treatment of the bio-lube before usage
• Filling bio-lube into oil system through three
micron filter
• Maintaining moisture level below 800 mg/kg
benefits the oil life time
• Achieved cleanliness level much better than
recommended enhances reliability of the
machine, less breakdowns

19. Dedicated CJC oil conditioning units:
1. Limited moisture ingress: dedicated unit is
HDU type utilizing B27/27 inserts and electric
preheaters. Absorptions of moisture and
retentions of particles and oxidation by-
products.
2. Continuous (sea)water ingress: dedicated
units are combination of Desorber type D10 or
D30 and HDU type utilizing BLA27/27 inserts for
retention of salt, dirt and oxidation by-products.
