2.0 – PRODUCT OVERVIEW
CLEO High Temperature Environmental Oil Key Competitive Parameters
CLEO is a High Temperature Environmental Oil based Subsea Fluid.
CLEO was developed to bridge the technology gap between water based fluids and the extreme
HT/HP developments of the future by providing a very stable high temperature fluid capable of
maintaining temperatures in excess of 250°C for a project lifetime.
In addition, with the potential future requirements for closed loop systems in some sectors this
environmental oil is not only acceptable for direct discharge to sea but is designed to offer all the
properties of traditional oil based fluids in closed loop systems.
CLEO has a comparatively low viscosity for an oil based fluid which is useful when the fluid is to be
used in fields with long step‐outs.
CLEO is fully compatible with Brayco Micronic SV/3 and SV/B and can be used to replace such
fluids in existing systems where a stronger focus on environmental discharge is required.
This manual summarises some of the key technical parameters of the fluid and includes all
relevant ISO 13628‐6 (2012) Annex C criteria along with a wide range of additional materials
tested. Further updates will be available in future as fresh data becomes available.
Information given in this publication is
based on Technical Data gained in our own
and other laboratories and is believed to be
true. However, if the material is used in
conditions beyond our control, we can
assume no liability for results obtained or
damaged incurred through the application

4.0 – PRODUCT TEST SPECIFICATIONS
4.1 – Thermal Stability
4.1.1 – Thermal Stability – Accelerated Aging
This test shall be performed whenever the control system operating fluid is intended for service
above 80°C (176°F).
METHODS AND MEASUREMENTS
The neat fluid is exposed at the maximum temperature specified by the fluid supplier plus a safety
margin of 10 °C (18 °F), or at the maximum operational temperature for a specific subsea project
plus the same safety margin.
Fluid is exposed for 2, 6 and 12 months. The approval can be issued after 6 months, but the test
shall continue through to 12 months to verify the 6 months result.
Visual inspection of fluid and solids formed, viscosity, lubricity, and final fluid volume are all
measurements used to validate the thermal stability.
PROCEDURE
Select aging vessels that are of 316 or better quality stainless steel for wetted components. An
inner lining of PTFE is recommended.
Clean the three test vessels/liners in accordance with ISO 3722 and for the final rinse use either
filtered de‐ionized water for water‐based fluids or filtered petroleum spirit for oil‐based fluids. Let
the vessels dry in a clean lint‐free environment. Do not use an air line to dry the vessels, as this
introduces contamination. Test for vessel cleanliness by filling with 150 ml (9.15 in3) de‐ionized
water (petroleum spirit for oil‐based fluid test), agitate, and then count particles. The acceptance
criterion is less than 150 particles greater than 5 μm per 100 ml (6.1 in3) of fluid volume.
Fill vessels with a minimum of 400 ml (24.4 in3) of the control fluid.
Purge the air space above the control fluid with dry filtered nitrogen and regulate the pressure to
a value sufficient to prevent boiling of the control fluid. Maintain this pressure throughout the
test.
Heat the vessels to the desired temperature and maintain ± 1% throughout the test.
A minimum of three 400 ml (24.4 in3) fluid samples are exposed for 2 months, 6 months and 12
months, in a separate vessel for each period. After testing the whole content of the vessels is
retrieved. This includes the liquid as well as any solids which may have collected at the bottom or
walls and cover of the vessel. After retrieval of the sample from the autoclave, any solids are
collected, dried and weighed to the nearest mg according to ISO 4405. A volume of 200 ml (12.2
in3) from each sample is reserved for the low‐temperature stability testing, (see 4.2)

The appropriate measurements are carried out and changes relative to the unused fluid are
calculated. To avoid changes in the fluid properties after the vessel has been opened; the visual
observations are done within 8 h after opening of the vessel, and shall be documented by photos.
Test for fluid lubricity and wear (see section 4.9) before and after exposure to the maximum
temperature.
ACCEPTANCE CRITERIA
The acceptance criteria are as follows.
Visual appearance: The fluid shall not change significantly in appearance. Fading of the
initial colour is acceptable.
Fluid separation: No secondary liquid phase and no substantial amount of particles/sludge
shall form in the fluid. Maximum content of collected solids (deposits) shall not exceed
100 mg/l of fluid.
Lubricity: Lubricity shall comply with the acceptance criteria in the fluid lubricity and wear
section 4.9.
Viscosity: The viscosity shall not change by more than 10%.
Fluid volume: The retrieved volume of the fluid shall be at least 99% of the original
volume.
RESULTS
The results after ageing CLEO for six months are tabulated below and are all within acceptable
limits.

4.3 – Seawater Compatibility for Synthetic Fluids
Four tests are required to investigate the tolerance of synthetic fluids to seawater:
Determination of the saturation point of the synthetic fluid
Investigate seawater compatibility under static and dynamic conditions
Determine the dewatering capability of the synthetic fluid
Water absorption test.
Note: Artificial seawater (ASTM D1141‐98) shall be used.
4.3.1 – Determination of the Saturation Point of the Synthetic Fluid
METHODS AND MEASUREMENTS:
A quantity of artificial seawater is added to the oil and dissolved. Absolute water content and %
saturation are measured and from this the saturation point of the oil is determined.
This test should be carried out in clear plastic bottles. If glass bottles are used, the added water
will adsorb to the vessel and may lead to false results. Water does not adsorb onto plastic.

Note readings of % saturation are not instantaneous. It will take time for the moisture in the oil to
interact with the sensor. Whilst taking a reading, stir the oil so that fluid is flowing past the sensor,
until the % saturation reading has stabilised.
PROCEDURE
Take a sample of the oil and measure the % saturation of the oil at 20°C and determine its
absolute water content by Karl Fischer. Estimate how much seawater to add to achieve a %
saturation of 80 to 85% at 20°C.
Add the appropriate quantity of artificial seawater to the oil sample, making sure that the drops
of water head to the bottom of the bottle.
Put the bottle into a normal laboratory ultrasonic bath and then gently swirl the bottle as the
“mist” of tiny droplets rises away from the larger drops of water. Do this until the “mist” is no
longer visible. This can take 30 minutes or more. After this, put the bottle on a magnetic stirrer or
bottle roller for minimum 12 hours (e.g. overnight). This will allow the tiny droplets to dissolve
fully.
Finally measure the % saturation at 20°C. If the % saturation is above 85% add fresh oil and allow
it to mix thoroughly, sufficient to bring it to the 80 – 85% target. Re‐measure the % saturation at
20°C and the absolute moisture content (Karl Fischer).
ACCEPTANCE CRITERIA
There are no acceptance criteria for this test.

4.3.2 – Seawater Compatibility under Static and Dynamic Conditions
STATIC TESTING
Carefully add, without mixing, 5% and 10% (by weight) of artificial seawater to the synthetic fluid.
Record the initial observations. The mixtures are then exposed at 5, 20 and 70°C for 4 weeks. The
appearance of the mixtures are recorded weekly and compared with the neat fluid.
Use a suitable jar with a lid for the test.
METHODS
Visual inspection.
ACCEPTANCE CRITERIA
No visual solids sedimentation.
RESULTS
Test Complete.
CLEO remained clear and bright at both 5 and 20 °C throughout the test. At 70 °C CLEO also
remains clear and bright; however it then becomes hazy on cooling do to the fluid being fully
saturated with sea water.

4.3.4 – Dewatering Capability of Synthetic Fluid
The purpose of this section is to verify that the moisture absorption process is reversible.
Note: It is recommended that this testing is carried out by a specialist company supplying drying
equipment to the offshore industry.
METHODS
Water content (ppmw) and % saturation measurement by suitable methods, check with fluid
supplier.
PROCEDURE
This will depend on the qualification procedure of the external specialist company. In principle, a
sample of the synthetic fluid will be dosed above the saturation point with artificial seawater. The
sample will then be run through the drying equipment at 20 °C (±5 °C), and samples taken
periodically for % saturation, using the moisture sensor and water content (ppmw).
ACCEPTANCE CRITERIA
After 35 circulations of the test fluid, the moisture level shall as a minimum have fallen from 80%
to 30% of the saturation point, as determined in section 4.3.1.
RESULTS
Tests were carried out using a Pall HPN021 oil drying unit, with a fluid flow rate of 21 L min‐1 and a
typical vacuum of 0.7 Bar.
The moisture level equivalent to 80% saturation of CLEO was determined as 2500 ppm water,
with 30% saturation equivalent to 200 ppm water.
The drying test was carried out in triplicate and the results are shown overleaf.
The results show that CLEO meets the requirements in ISO 13628‐6 2012 Annex C as the water
content is reduced from >80% saturation to <30% saturation within the 35 cycle limit.

4.3.5 – Water Absorption Test
METHODS AND MEASUREMENTS
The purpose of this test is to measure the capability of the oil to absorb water (i.e. the blotter
paper functionality). The test oil is carefully added to artificial seawater and then stirred. The %
saturation of the oil is measured over time until 80% saturation is achieved.
Procedure
This test should be carried out at 20°C. Add 40 grams of artificial seawater (20% w/w) to a 400ml
tall form glass beaker. Carefully add 200 grams of dry test oil (≤ 20% saturation at 20°C). Place a
magnetic follower in the water phase. Use an overhead stirrer to stir the oil phase. Place the
paddle of the overhead stirrer in the middle of the oil phase. Set the overhead stirrer speed such
that the oil / water interface is not broken and there is no vortex generated. Set the speed of the
magnetic follower such that the water phase is gently moved around but the interface is not
broken. This may be as little as 100rpm. The stirring is designed to gently move the oil over the
water phase and continually move it past the moisture sensor. Place the moisture sensor so that it
is in the middle of the oil phase. Record the % saturation at time intervals, for example every 15
minutes, until the oil reaches 80% saturation.
ACCEPTANCE CRITERIA
There are no acceptance criteria for this test.

The results for water absorption test for CLEO and Sea water are tabulated below and in the

4.5 – Completion Fluid Compatibility
METHODS AND MEASUREMENTS:
The control fluid is mixed with specific completion fluids in defined mixing ratios at 5 and 20 °C.
PROCEDURE
The control fluid is mixed with the following completion fluids in the volume mixing ratios:
99.5:0.5, 99:1, 98:2, 95:5, and 90:10 (mixing ratios are defined as control fluid : contaminant) (%
completion fluid) mixing ratios:
Calcium chloride (CaCl2), calcium bromide (CaBr2), zinc bromide (ZnBr2), zinc chloride (ZnCl2),
potassium formate (K‐formate) and caesium formate (Cs‐formate). The actual brines shall be
selected from commercially available products, and the type, brand and other relevant data shall
be included in the report.
The samples are exposed at 5 and 20 °C for 4 weeks. The mixtures are shaken vigorously on
mixing and on intervals (1, 7, 14 and 21 days). The appearance of the mixtures and formation of
separations are observed instantly after being shaken, after 1 hour, 1 day, 1 week and 4 weeks.
ACCEPTANCE CRITERIA
There are no general acceptance criteria related to this property. The results have to be evaluated
for the individual projects for which they are relevant. It is up to each specific project to define
project‐related criteria if this is considered necessary.
RESULTS
Results for each fluid mixture with CLEO are outlined below. Results are broadly as expected
when mixing with water based control fluids.

4.6 – Compatibility with Miscellaneous Operational Fluids
METHODS AND MEASUREMENTS
The control fluid is mixed with other relevant operational fluids in the specified volume mixing
ratios at 5 °C (41 °F), and 20 °C (68 °F) and exposed for 4 wks.
PROCEDURE
The control fluid is mixed with the operational fluid in a mixing ratio which depends on the
secondary fluid. Mixing ratios are defined as control fluid : contaminant.
35% hydrochloric acid, in the following volume mixing ratios: 99.5:0.5; 99:1; 98:2; 95:5
and 90:10.
For methanol: 95:5; 90:10; 75:25 and 50:50.
Compensation fluids (HDEO): 95:5; 90:10; 75:25 and 50:50.
Silicon oil: 99:1
MEG: 100‐ and 1000 ppmw MEG in oil
The samples are exposed at 5°C (41°F) and 20°C (68°F) for 4 wk. The mixtures are shaken
vigorously on mixing and on intervals (1, 7, 14 and 21 days). The appearance of the mixtures and
formation of separations are observed instantly after being shaken, after 1 hour, 1 day, 1 week
and 4 weeks.
ACCEPTANCE CRITERIA
There are no general acceptance criteria related to this property. The results have to be evaluated
for the individual projects for which they are relevant. It is up to each specific project to define
project‐related criteria if this is considered necessary.
RESULTS
Results for each fluid mixture are outlined below for CLEO and results are broadly as expected
when mixing with miscellaneous operational fluids.

4.7 – Metal Compatibility
4.7.1 – Metal Compatibilities at 70 °C
METHODS AND MEASUREMENTS
Tests are carried out in the neat fluid and aged for 3 weeks, 6 weeks and 12 weeks following the
methodology laid out in ISO 16328‐6 Annex C Protocol with the following deviations / extensions.
The test pieces were aged at 70 °C, which is more severe than the 60 °C testing required
in ISO 13628‐6
The following methods are used to evaluate compatibility:
change in appearance of fluid relative to unused fluid;
appearance and amount of solid deposits (particles, sludge) in the fluid and on the metal
samples;
qualitative description of corrosion products and corrosion attacks (attacks which are
clearly related to edges or fixture holes are disregarded);
mass loss as a function of time, transformed into micrometres per year uniform corrosion;
PROCEDURE
The ready‐made metal samples, which have a standard surface area and a standard surface
condition, are degreased, dried and weighed to the nearest 0.1 mg and then immersed in both
the neat control fluid, and in the presence of 10% sea water. It should be noted that when sea
water is present, the metal is exposed completely in the control fluid phase and not the sea water
phase.
Tests were carried out in glass vessels at 70 °C. Each of the individual metals is exposed in a
separate container in a number of nine replicate specimens, with three replicates are retrieved
from the fluid after 3 weeks, 6 weeks and 12 weeks. After visual inspection of the samples and
after appropriate cleaning, weight loss is measured and the samples inspected for visible
corrosion attacks, which are characterized. The weight losses are transcribed into uniform
corrosion, in micrometres per year, and maximum depth of local attacks, in micrometres, is
determined under a microscope with a calibrated depth of focus. The fluid is inspected for any
separations, including solid particles or sludge.
ACCEPTANCE CRITERIA
No substantial visible corrosion products or attacks on any of the metals,
No significant amounts of deposits (particles or sludge) in the fluid at the end of the test
period,
Corrosion rates shall show a clear declining tendency with time.
Corrosion rate of the carbon steel including galvanic coupling shall not exceed 10 μm/year
(12 weeks result).

4.7.3 ‐ AISI 316 Compatibility with Production Control Fluid and 10% Natural Sea Water
Tests are carried out in the neat fluid and aged for 3 weeks, 6 weeks and 12 weeks following the
methodology laid out in ISO 16328‐6 Annex C Protocol with the following deviations / extensions.
The test pieces were aged at 70 °C, which is more severe than the 60 °C testing required
in ISO 13628‐6
The following methods are used to evaluate compatibility:
change in appearance of fluid relative to unused fluid;
appearance and amount of solid deposits (particles, sludge) in the fluid and on the metal
samples;
qualitative description of corrosion products and corrosion attacks (attacks which are
clearly related to edges or fixture holes are disregarded);
mass loss as a function of time, transformed into micrometres per year uniform corrosion;
PROCEDURE
The ready‐made metal samples, which have a standard surface area and a standard surface
condition, are degreased, dried and weighed to the nearest 0.1 mg and then immersed in both
the neat control fluid, and in the presence of 10% sea water. It should be noted that when sea
water is present, the metal is exposed completely in the control fluid phase and not the sea water
phase.
Tests were carried out in glass vessels at 70 °C. Nine replicate specimens are exposed in a single
container, with three replicates are retrieved from the fluid after 3 weeks, 6 weeks and 12 weeks.
After visual inspection of the samples and after appropriate cleaning, weight loss is measured and
the samples inspected for visible corrosion attacks, which are characterized. The weight losses are
transcribed into uniform corrosion, in micrometers per year, and maximum depth of local attacks,
in micrometers, is determined under a microscope with a calibrated depth of focus. The fluid is
inspected for any separations, including solid particles or sludge. In addition examination and
characterization with respect to SRP activity before and after the test is carried out.
ACCEPTANCE CRITERIA
No substantial visible corrosion products or attacks on any of the metals,
No significant amounts of deposits (particles or sludge) in the fluid at the end of the test
period,
Corrosion rates shall show a clear declining tendency with time.
Corrosion rate of AISI 316 shall not exceed 5 μm/year (12 weeks result). Maximum depth
of local attacks shall not exceed 25 μm.

4.7.4 – Metal Compatibility at 250 °C
METHODS AND MEASUREMENTS
Tests are carried out in the neat fluid and aged for 2 and 6 months following the methodology laid
out in ISO 13628‐6.
The following methods are used to evaluate compatibility:
change in appearance of fluid relative to unused fluid;
appearance and amount of solid deposits (particles, sludge) in the fluid and on the metal
samples;
qualitative description of corrosion products and corrosion attacks (attacks which are
clearly related to edges or fixture holes are disregarded);
mass loss as a function of time, transformed into micrometres per year uniform corrosion;
Test at maximum temperature plus 10 °C (18 °F) is carried out in a suitable autoclave made of AISI
316 or better quality material, preferentially lined by PTFE, pressurised to an appropriate level to
prevent boiling (depends on the test temperature). Both materials (AISI 316 and AISI 17‐4 PH,
both with crevice) are exposed in triplicate for each testing period. The test is run for 2 months, 6
months and 12 months in a separate vessel for each testing period. At the termination of the test
the same procedure as for section 2.2 is followed. The results are reported for approval after 6
months.
For synthetic oil based fluids: For the high temperature tests, AISI 316 shall be exposed to the
control fluid and the seawater. 17‐4PH shall only be exposed to the control fluid. Both sets of
metal samples can be exposed in the same container. The vessel should not be purged with
nitrogen before pressurisation, in order to maintain atmospheric air in the vessel.
ACCEPTANCE CRITERIA
No substantial visible corrosion products or attacks on any of the metals.
No significant amounts of deposits (particles or sludge) in the fluid at the end of the test
period.
Corrosion rates shall show a clear declining tendency with time.
Corrosion rate of the carbon steel including galvanic coupling shall not exceed 10 μm/year
(12 weeks result).
Corrosion rate of AISI 316 shall not exceed 5 μm/year (12 weeks result). Maximum depth
of local attacks shall not exceed 25 μm.
Corrosion rate of 17‐4PH shall not exceed 5 μm/year (12 weeks result) and maximum
depth of local attacks shall not exceed 25 μm.
Corrosion rate of electroless nickel shall not exceed 2 µm/year (12 weeks result).

The results show CLEO meets all the acceptance criteria laid down in ISO 13628‐6 with respect to
metal compatibility at 250 °C for compatibility with Stainless Steel grade 316. The 17‐4‐PH (UNS
S17100) material is showing slight deposits upon extended aging at these elevated temperatures.
Offshore Environmental Oils do not recommend the use of either of these materials at such
elevated temperatures, particularly if the ingress of sea water is likely.
It is generally not recommended that 17‐4‐PH (UNS S17400) or Stainless Steel AISI 316 are used
at such high temperatures in the field with sea water present and that more suitable materials are
selected for field operation at such elevated temperatures.
As a result, we do not recommend the use of Stainless Steel AISI 316 or 17‐4‐PH materials at such
elevated temperatures in the field, particularly if the ingress of sea water is likely. It is also our
opinion that the use of Stainless Steel AISI 316 and 17‐4‐PH within the ISO specification at

elevated temperatures should be reconsidered in light of the new higher temperatures reached
by CLEO.
4.7.5 – Additional Metal compatibility at 250 °C
METHODS AND MEASUREMENTS
Tests are carried out in the neat fluid and aged for 3 weeks, 6 weeks and 12 weeks and are based
on the methodology laid out in ISO 16328‐6 Annex C Protocol for water based subsea fluids
(without sea water) as outlined in section 4.7.1 with the following deviations / extensions.
The test pieces were aged at 250 °C.
Single test pieces only were used as indicated.
Testing in the neat fluid alone was undertaken.
Further testing after 18 weeks aging is also reported, with further testing on‐going.
ACCEPTANCE CRITERIA
No substantial visible corrosion products or attacks on any of the metals.
No significant amounts of deposits (particles or sludge) in the fluid at the end of the test
period.
Corrosion rates shall show a clear declining tendency with time.
Corrosion rate of AISI 316 shall not exceed 5 μm/year (6 months result) and maximum
depth of local attacks shall not exceed 25 μm.
Corrosion rate of 17‐4 PH shall not exceed 5 μm/year (6 months result) and maximum
depth of local attacks shall not exceed 25 μm.
RESULTS
The results for CLEO are shown overleaf.
Whilst the materials below show excellent compatibility at 250 °C within the fluid, this is not a
recommendation on suitable materials for use at this temperature, rather a demonstration that
the fluid has excellent corrosion protection abilities. For projects operating at such severe
temperatures, careful material selection is advisable based on operational requirements.
All metals tested have a corrosion rate of less than 2 µm per annum after 12 weeks aging at 250
°C which is an order of magnitude below the limit of 10 µm per annum specified in ISO 13628‐6.
Extended testing for these materials is currently on going, and will be expanded to include other
metals in future.

It should be noted that Monel K500 autoclaves were used for the tests containing sea water, as
stainless steel 316 is not deemed resistant to sea water at the temperatures involved (250 °C).
The 17‐4‐PH (UNS S17400) material as also omitted from the sea water test as it was found not to
be corrosion resistant to sea water at 250 °C.
The stainless steel 316 pieces were approximately 40 ‐ 50% covered in sea water in these test, and
further testing is planned with the test pieces immersed only in the oil phase in the presence of
sea water at 250 °C.
Further results will be available in Q2 2013 but it is generally not recommended that 17‐4‐PH
(UNS S17400) or AISI 316 are used at such high temperatures in the field with seawater present
and that more suitable materials are selected for field operation at such elevated applications.
As a result, we do not recommend the use of Stainless Steel 316 or 17‐4‐PH materials at such
elevated temperatures in the particularly if the ingress of sea water is likely.
It is also our opinion that the use of Stainless Steel 316 and 17‐4‐PH within the ISO specification at
elevated temperatures should be reconsidered in light of the new higher temperatures reached
by CLEO.

At high temperature: PTFE, PEEK, Perfluoroelastomer 90 and HNBR 90 (Parker N3512‐90 Skega
63‐90‐093, BusakShamban H9T40) up to 120oC (248°F).
The following methods are used:
Visual inspection of fluid
Macro‐ and microscopic inspection of the test materials
Volume change for materials
Weight change
Hardness change (Shore A or D) for materials.
PROCEDURE
The procedure is based upon ASTM D471 without tensile testing.
The test specimens are weighed in air and in water and the Shore A or D hardness is measured.
At 70°C (158°F) and the maximum temperature plus 10 °C, three replicate samples are exposed in
the fluid. A separate vessel is used for each material. The same samples are by re‐exposure used
for the exposure periods of 1 week, 1 month and 3 months, respectively. Volume change, weight
change and change in hardness are measured for each sample after each testing period. At the
termination of the test, the test specimens are also investigated with respect to change in
appearance and formation of cracks.
ACCEPTANCE CRITERIA
No visible effect of the tested polymers on the appearance of the fluid.
The appearance of the polymer materials shall not change during the test (some staining
by the fluid is permitted for materials which tend to discolour).
Volume change shall not exceed the range ‐5 % to 10 % at either temperature.
Hardness change shall not exceed 10 % at either temperature.
The development in volume and hardness change with time shall show a clear tendency
to stabilization.

METHODS AND MEASUREMENTS
Both of the following tests have been applied using an independent test laboratory:
1. Shell 4 Ball test (IP 239).
PROCEDURE
1. Shell 4 Ball test (IP 239). The details of the test procedure are given in the IP239. The test
is twofold:
Weld point test – gives an indication of load carrying capability. The steel ball is
loaded and rotated against 3 fixed steel balls for 10 seconds. A rotation speed of
1460 is used. At the end of each 10‐second run, a further weight is loaded onto the
balls and the test re‐run using fresh fluid. The test stops when the balls weld
together. The weld point is the load at which this occurs.
1 hour wear test – gives an indication of the prevention of metal wear. The load and
speed of rotation is fixed to 30kg and 1460 rpm at the start of the test. Fresh fluid is
added and the test is run for 1 hour. After the test, the scars on the 3 fixed balls are
measured and an average taken. This is the Mean Wear Scar Diameter (MWSD).
RESULTS
This testing was conducted independently.
Results obtained for CLEO exceed the requirements in ISO 13628‐6 in all aspects.
4.9.1 – 4 Ball Weld Point Load
The results on the initial weld point tests are given in Table 1 of this report, which shows the weld
point load determined for the two fluids supplied. All tests were started at an initial test load of
40kg and ended at the weld load was achieved. A 10 second load step duration was used for
these tests. The weld point achieved was higher than the minimum 120 kg acceptance criteria
advised by Offshore Environmental Oils.

4.10 – Filterability
METHODS AND MEASUREMENTS
300 ml (18.3 in3) of control fluid is filtered under specified conditions through a 0.8 µm filter
membrane at a controlled pressure drop of 0.05 MPa (7.25 psi). Filterability is calculated from the
ratio of filtration near the start of filtration, to the filtration rate at specified higher filtered
volume.
PROCEDURE
Reference is made to ISO 13357‐2[43]. The test results should be reported based on “Stage II” only.
The test membranes specified in the standard might not be compatible with water/glycol‐based
control fluids, in which case suitable membranes have to be located. The specified filtration rating
(0.8 µm) shall apply.
For synthetic based oils, the same procedure but with dry and wet oil (0.5% ± 0.05% artificial
seawater added and vigorously mixed in – ultrasound for 1 hour. The sample shall be left for > 10
hours at room temperature, shaken well and then ran through the test). The test membranes
specified in the standard might not be compatible with synthetic oil based control fluids, in which
case suitable membranes have to be located. The filtration rating for this test shall be 1.2 µm.
RESULTS
The result is the ratio between the flow rate at the start of filtration and the flow rate between
200 ml (12.2 in3) and 300 ml (18.3 in3) of filtered volume, and expressed as a percentage.
ACCEPTANCE CRITERIA
The required stage II filterability is 80% or above.
For wet oil: Required stage II filterability requirement is 20% or above.

4.11 – Bacterial & Fungal Resistance with Seawater
METHODS AND MEASUREMENTS
Bacterial and Fungal resistance is tested by mixing CLEO with synthetic seawater at a ratio of
50:50.
The mixtures will then be aged at temperatures of ambient and / or 40 °C. The level of microbial
infection is monitored on a weekly basis up to 12 weeks and on a monthly basis thereafter. Two
sets of mixtures have been aged as follows:‐
(1) Control fluid with contaminated sea water – ambient and 40 °C.
(2) Control fluid with uncontaminated sea water – ambient and 40 °C.
PROCEDURE
The level of infection is ascertained by immersing a BTM2 dip slide into the test fluid and
incubating the dip slide and comparing the growth with the charts (see overleaf).
The microbes that are highlighted using these dip slides will be bacteria, yeasts and fungus
(moulds). The bacteria form colonies on the colourless agar and the yeasts and moulds form
colonies on the brown agar.

No bacterial or contamination has been found to date when mixing CLEO with contaminated sea
water. Extensive mould is formed in the sea water sample aged in the absence of any production
control fluids. This suggests that CLEO does not support or promote the growth of bacteria or
fungi in the presence of sea water. Longer term tests are currently on going.
The appearance of both the aged mixtures and the microbial plates are shown overleaf.
