2. BOP Fluids BOP Fluid Types Fluid Physical and Chemical Properties
Fluid Maintenance
Ancillary Products
Flushing and Sterilisation Procedures
Environmental Issues
Health and Safety

3. History of BOP Fluids First BOP fluids were normal Hydraulic Oils
High Viscosity
No Seawater Tolerance
Flammable
Compressible
Lighter Than Seawater

4. History of BOP Fluids Soluble Oils More Environmentally Acceptable
Closer SG to Seawater
Less Flammable
Easier to Store
Low Viscosity
Susceptible to Instability
Too Biodegradable

5. History of BOP Fluids Polymer Solutions
Much More Environmentally Acceptable
Easier to Store
Non Flammable
Stable
Micro-organism Resistant
Low Viscosity

6. Modern BOP Fluids 100-50:1 Dilution Low Toxicity High Biodegradability
Low Viscosity
Extremely Stable (even with seawater)
Good Lubrication
Corrosion Resistance
Microbiological Resistant

7. Components in Modern BOP Fluids
Corrosion Inhibitors, Normally Amine Based
Lubricants, Many Types Used
Biocides
Surfactants, Soaps or Solvents.

8. Main BOP Fluids on The Market
Stackmagic 200
Stackmagic 200N
UK 50
Erifon HD856
Erifon HD2000
Erifon HD603
Erifon Pilot Line Fluid

9. Stack Magic Manufactured by Houghton Vaughn
100:1 mix, Good all round fluid
High resistance to micro-organisms
Poor toxicity figures
Stackmagic 200N appears to have some biocide removed. Still does not have very good toxicity figures but is acceptable to SFT and DTI.

10. UK 50 Manufactured by Blacksmiths 50:1 mix ratio or premixed
Green in colour

11. Erifon HD 856 Approved by all equipment manufacturers. Diluted 100:1
For general use
Relies on Molybdenum for lubrication
No up to date HOCNF
Being phased out

12. Erifon HD 2000
100:1 Dilution.
Developed primarily for use in South East Asia.
Extremely resistant to microbiological attack.
Because of high temperatures and poor water supply.

13. Erifon HD 603 100:1 to 50:1 mix Newest fluid on the market
Incorporates advantages of HD856 and HD2000.
Most environmentally acceptable fluid on the market.
Recommended by all BOP equipment manufacturers.

14. Physical Properties of Erifon HD603

15. Important Physical Properties
The most important indicator of problems and property to maintain is the pH.
This maintains bacterial resistance. Low pH indicates presence of micro-organisms.
And corrosion inhibition. Low pH will cause corrosion.
