Description
(Subsea Production Control Fluids)
High-performance, water-based hydraulic fluids. Oceanic HW500 fluids are used in open and closed loop Subsea Production control systems and as industry standard fluids are specified by equipment manufacturers. Oceanic HW500 series are compatible with each other and offer the same excellent technical performance. Fluids differ in glycol content to make sure optimal response times in all geographical regions. Variants of Oceanic HW500 fluids are also available for local/customer requirements (e.g. Oceanic HW500 P/XP/No Dye fluids).

Storage
Oceanic HW500 fluids should be stored in dry conditions, ideally out of direct sunlight. Normal storage temperature range is 5 to 40°C.
Material Compatibility
Oceanic HW500 fluids contain performance additives which ensure high levels of compatibility with materials typically used in subsea production control equipment. Extensive material compatibility tests have been performed with Oceanic HW500 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 thermoplastics | Compatible with Nylon 11, PE and Polyether ester copolymers. |
| Absorbent gasket materials | Avoid cork, leather, cotton impregnated materials. |
| Paints | Avoid 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 elements | Polypropylene and glass fibre filter elements recommended over paper filters. |
