1 GENERAL
This specification details the requirements, test methods and terms of delivery for lu-
bricating (lube) and control oils, which ALSTOM uses in steam and gas turbines.

2 SCOPE OF APPLICATION
The mineral oils in accordance with this specification are refined mineral oils classi-
fied as Group I, II or III oil according to the American Petroleum Institute. These min-
eral oils contain additives, which increase resistance to ageing and improve protec-
tion against corrosion. Small quantities of other additives may also be added to
achieve the required properties.
Mineral oils in accordance with this specification can be used in the turbomachinery
lube and control oil systems .
AA 2016-06-24 EN Approved

Note
Lng. Status

It is not permitted to use mineral oil as control oil in hydraulic high pressure sys-
tems with a pressure > 120 bar

2.1 Viscosity classes

Type
DF

Mineral oils of viscosity classes ISO VG 32 and 46 are used for steam or gas tur-
bines.
9665 HTGD 90117

ALSTOM uses viscosity class ISO VG 46 if the bearing oil inlet temperature is be-
Dept. Document No.

tween 40 °C and 50 °C (104 °F and 122 °F).

Mineral oils of viscosity class ISO VG 32 can be used up to a bearing oil inlet tem-
perature of 45 °C (113 °F). These mineral oils are less suitable for turbosets with
higher bearing oil inlet temperatures.
The use of mineral oils of viscosity class ISO VG 68 is possible with very high bear-
ing oil inlet temperatures.
ALSTOM’s Engineering Department responsible, has to be principally consulted for
approving the viscosity class.

2.2 Terms of delivery

Depending on the agreement made between supplier and customer, the oil is sup-
plied in tank cars or in clean, solid and dry barrels. The following minimum infor-
mation has to be provided in a legible and durable manner on each barrel:
• Designation of type and viscosity class
• Identification of product and supplier
• Charge or delivery number

en HTGD 90 117 V0001 AA 5

 MAINTENANCE

Note
When placing the order, a test certificate has to be requested from the supplier for
the supplied mineral oil.
The delivery must not be accepted if this condition is not fulfilled.
Ordering an infrared spectrum and the viscosity index of the delivered oil charge is
recommended.

2.3 Notes on acceptance and first filling of the lube oil tank
The check of and procedure for acceptance on delivery and first filling of the lube oil
tank are given in the checklist to be completed.
A copy of this checklist has to be sent to the ALSTOM Project Manager.

When checking an approx. 10 cm thick oil film in transilluminating light, the oil must
be bright and clear and free of visible foreign matter. The additives must not have
negative effects on the materials of the oil system.

 MAINTENANCE

Notes on Table 2.
1)
For turbine types that are presently available. When turbines are operated with
oils that do not comply with this specification but do not cause problems, the oil
filling can be left.
2)
ALSTOM uses viscosity ISO VG 46. The viscosity must be defined for each plant
separately, depending on the oil temperature to be expected.
3)
The viscosity index (VI) is a measure of the viscosity and temperature correlation.
The requirement for the index is fulfilled when all viscosity values measured at
temperatures between 20 °C and 100 °C (68 °F and 212 °F) or determined by ex-
trapolation are within the range valid for this viscosity class. See the viscosity
characteristics in the graph, Figure 1. Viscosity index improvers are not permitted
because long-chain paraffins can cause clogging of the filter.
4)
The pour point must be at least 10 °C below the lowest ambient temperature in
winter, or a heater is required. An oil with a lower pour point, which is not listed
AA 2016-06-24 EN Approved

as an approved oil, can be used for special applications.

Lng. Status

5)
There is no sufficiently reliable correlation between demulsibility according to DIN
51589 and water separability according to ISO 6614 or ASTM D 1401. It depends
on the national regulations of the country where the oil is used which of the two
Rev. Released

criteria has to be fulfilled.

6)
The limit value for new oil is not defined. The measurement is important as a ref-
Type

erence value.
DF

7)
For turbines with gear an FZG fail level of at least 8 is required, these are mineral
oils with anti-wear or extreme pressure, AW/EP, additives. The gear manufactur-
9665 HTGD 90117

er may require other FZG fail levels for individual plants.

8)
Equivalent test methods, for example DIN, NF, IP and BS methods can be used.

3.1 Sampling
Take the oil samples for the monthly check of appearance and water content from
the lower third of the oil tank.

Note
Take the annual, overall condition oil sample from the pressure line downstream of
the filter.

Note
The oil system must have been in operation for at least 12 hours before taking the
sample!
AA 2016-06-24 EN Approved

Prior to the actual sampling, discharge approx. 3 to 4 litres of oil for flushing the
Lng. Status

valves. The sample must be approximately 1 litre. Rinse the clean sample container
three times with oil.
The valve must not be closed between flushing and sampling. After taking the sam-

ple, close tightly the sample container. When the test is not done in the plant's own
laboratory, the container must indicate the following information:
• Plant name
Type
DF

• Oil brand
• Sampling point

3.2 Explanatory notes on the tables

Appearance
You must leave the oil to settle for 10 minutes. Check if the 10 cm thick oil film is free
of visable foreign matter when viewed in transilluminating light.

Solid impurities
The solid impurities are classified in the following purity classes in accordance with
their number and size per volume unit.

Caution
Equipment Damage
Solid particles larger than 150 microns are not permitted!
When the lube oil is also used as control oil, it must have a purity per SAE AS4059
class 7 or ISO 4406 class --/16/13!

4 REFILLING THE OIL TANK

The lube oil tank must be refilled with oil of the same brand and viscosity class.
When a definite lube oil is no longer available on the market, it is recommended to
consult the oil supplier to make sure a suitable replacement oil is available.
Refill the clean lube oil system through a filter with a mesh size of 10 µm to remove
impurities.

Note
Mixing different oils can cause accelerated ageing and precipitation of additives!

Record all refillings in order so changes in the oil can be correctly assessed.

5 SELECTION OF THE OIL SUPPLIER

Only mineral oils that meet the requirements of the specification table in Table 2. are
permitted.

5.1 Tested lube and control oils

The lube and control oils, tested and approved by ALSTOM on the basis of the spec-
ification table in Table 2, are given in Table 6.

Note
ALSTOM's approval does not exonerate the supplier from his responsibility
for the quality of his product.
The supplier must immediately inform ALSTOM when they change the name of a
product, its composition or the name of their company.
The oil supplier must confirm in writing every 5-years that the oils given in the list still
have the same composition and properties as stated in the table in chapter 2.5.

14 HTGD 90 117 V0001 AA en

 MAINTENANCE

The testing valability is a maximum of 20 years. This statement takes into account
the evolution in technoligies and in specifications.
After 20 years from the test date, the oil must be tested again, at the oil supplier’s
written request, or to be withdrawn from the approved oils list.

5.2 Untested lube and control oils

The following possibilities exist when a plant operator requests to use a mineral oil
that has not been tested by ALSTOM:
• The oil is tested in ALSTOM's laboratory in accordance with the specification ta-
ble in Table 2. and at the expense of the oil supplier. It is approved when all re-
quirements are met. The test requires approximately 4 months because of the
ageing test (2'000 hours).
• When ALSTOM agrees, some tests can be done in laboratories certified by
ALSTOM.
