(Equipment Storage & Preservation Fluids)

Oceanic EPF fluids are high-quality water-based fluids, use to protect the internals of hydraulic systems during long-term storage. Oceanic EPF fluids are compatible with Oceanic HW production control fluids, Erifon BOP and Erifon motion compensator fluids. Fluids differ in glycol content and geographic availability.

Key Benefits

  • Recommended for long-term storage
  • Excellent ferrous and non-ferrous corrosion protection properties
  • Superior vapor phase corrosion protection
  • Resistant to microbial infection
  • No colour taint of subsequent installed control fluid
  • Manufactured to NAS 1638/AS 4059 Class 6/6b-f or better cleanliness
  • Fully compatible with Oceanic HW Subsea Production Control fluids, Erifon BOP and Erifon motion compensator fluids
  • Meets stringent global environmental acceptability requirements
  • Free Fluid Monitoring programme able to optimise flushing & testing operations

Environmental Information

MacDermid maintains worldwide environmental approvals and can offer Oceanic Storage fluids suitable for use in every exploration and production region around the world. The current environmental status of Oceanic EPF fluids in your area can be acquired from our environmental specialists.


Oceanic should be stored in dry conditions, ideally out of direct sunlight. Normal storage temperature range is 5 to 40°C.

Material Compatibility

Oceanic EPF fluids contain performance additives which ensure high levels of compatibility with materials typically used in subsea production control equipment during long storage periods. Extensive material compatibility tests have been performed with Oceanic EPF fluids.

Ferrous metals (cast iron, carbon steel, low & high alloy steels, stainless steels…)Compatible
Non-ferrous metals (copper, brass, bronze and other metals and alloys*)…Compatible with alloys typically used in subsea production control equipment.
Avoid Zn, Cd, Pb and Mg metals. Aluminium should be hard anodised.
Coatings and ceramic materials Avoid porous coatings. Compatible with most ceramic parts. Check ceramic coatings.
Packaging & sealing materials
(elastomers and thermoplastics*)
Compatible with standard NBR, HNBR, FFKM, VMQ/FMVQ, CR, TFE/PTFE, PEEK.
Some FKM & AU/EU/PU have proven to be incompatible.
Umbilical hose liner thermoplasticsCompatible with Nylon 11, PE and Polyether ester copolymers.
Absorbent gasket materialsAvoid cork, leather, cotton impregnated materials.
PaintsAvoid painting internal surfaces
Cured epoxy, phenolic and nylon based paints are satisfactory. Avoid less resistant paints as they soften. Wash spillages immediately with water.
Filter elementsPolypropylene and glass fibre filter elements recommended over paper filters.
*As material compatibility varies from compound to compound and supplier to supplier, consult supplier for recommendations or request specific compatibility tests.
