Hydraulic systems are widely used to transmit power in the offshore industry
Hydraulic systems are found throughout an offshore installation: on cranes, drill floor power units and hydraulic ring mains. They are often located where leakage or spillage can escape into the marine environment. High pressures and large flow rates increase the environmental risk in the event of a hose failure. That’s why Castrol’s range includes environmentally responsible hydraulic oils. Reliable power transmission requires the use of highly stable hydraulic fluids with excellent anti-wear performance. Always check your equipment manual and consult with a Castrol Technical Service Engineer to choose the right product for the right application.
ANVOL CF 22
A water-based, fire-resistant hydraulic fluid formulated for use in floating drilling and production unit motion compensation systems, including heave compensators and riser, guide line and pod line tensioners. It suits being the operating fluid in closed loop surface blow-out preventer control systems. It is biodegradable and has good oxidation and thermal stability and is extremely resistant to hydrolysis.
The Castrol BioBar range of environmentally responsible synthetic hydraulic oils is an ideal drop-in replacement for conventional mineral oils where the risk of accidental spills or leakage could cause environmental pollution. Selected additives ensure good oxidation stability, good anti-corrosion and anti-wear properties and low aquatic toxicity. BioBar’s high viscosity index and low pour point provides excellent compatibility with elastomeric seal materials.
ANVOL PE 46X C
This HF-D type hydraulic fluid has excellent hydraulic performance and good fire risk protection. It suits applications where temperature limitations or other reasons mean water containing fluids are unsuitable. Designed for use in the electro-hydraulic governor control systems of steam turbines, Anvol PE 46 XC eliminates service problems in high pressure systems resulting from spool valve erosion/corrosion, fluid leakage and loss of response.
Castrol Hyspin AWS hydraulic oil is based on highly refined mineral oil enhanced with a low zinc containing anti-wear system. It has excellent hydrolytic and oxidative stability and a low tendency to produce sludge and deposits. It protects ferrous and yellow metal components found within a hydraulic system from corrosion.
Suitable for use in hydraulic systems and hydrostatic transmissions incorporating gear pumps, vane pumps, radial or axial piston pumps and motors used offshore, these premium high viscosity mineral oils are enhanced with anti-wear and anti-corrosion additives and a shear-stable viscosity index improver. This helps maintain viscosity over a wide temperature range and means it can be used in different equipment on board. It has excellent hydrolytic stability and separates rapidly from water contamination.
Castrol Hyspin HVI range of high viscosity index (VI) oils is based on an ashless (zinc free) additive system designed to meet and exceed the most exacting performance standards. It suits severely stressed hydraulic systems which require a high level of anti-wear performance and fine filtration. Hyspin HVI offers excellent corrosion protection and outstanding thermal and oxidative stability. It suits systems containing silver components.
The Hyspin VG range of hydraulic oils is based on highly refined mineral oil enhanced with rust and oxidation inhibitors. It is designed for use in hydraulic systems that do not require anti-wear performance but where rust and oxidation resistance is desirable and is also suitable for pumps with silver-plated components.
