Castrol Biobar 46 - Environmentally responsible hydraulic fluids - 6173

 

The Castrol BioBar range of high specification hydraulic oils are intended as drop-in replacements for conventional mineral oils in equipment where there is a risk of accidental spillage or leakage and consequent environmental pollution. Hydraulic systems are found throughout an offshore installation - on cranes, drill floor power units and hydraulic ring mains and are often located where leakage or spillage can escape into the marine environment. High flow rates, high operating pressures and extensive use of flexible hoses combine to make these systems vulnerable to rapid loss of fluid caused by chafe or mechanical damage.

Castrol BioBar contains selected additives ensuring good oxidation stability, good anti-corrosion and anti-wear properties and low aquatic toxicity. The combination of base oils used in Castrol BioBar endows it with a very high viscosity index and an extremely low pour point as well as giving excellent compatibility with elastomeric seal materials. The careful choice of the saturated synthetic ester enables the product to operate up to +120ºC system temperature.

The product level biodegradability of Castrol BioBar was measured in an extended OECD 306 (seawater) biodegradation test with a result greater than 60%, making it 100% more biodegradable than conventional mineral oils. This ensures its biodegradation should it enter the marine environment. The toxicity of Castrol BioBar was measured on 6 marine species and was found to be 100 times less toxic than conventional mineral oils. It also has > 50% less potential for bioaccumulation and > 30% of Castrol BioBar is derived from renewable sources.

Castrol BioBar is miscible with conventional mineral oil based hydraulic fluids. When changing from mineral oil based products to Castrol BioBar, the system should be drained to ensure that the mineral oil content of the refilled system is less than 5%. This is necessary to ensure that the maximum environmental benefit can be achieved.

 

Application

Hydraulic systems and hydrostatic transmissions incorporating gear pumps, vane pumps, radial piston or axial piston pumps and motors where there is a perceived risk of ingress into the environment in the event of spillage or leakage.

 

Benefits

Castrol BioBar hydraulic fluids combine excellent protection, extended drain performance and versatility in Offshore operations to provide the following key benefits:

  • High biodegradability, reduced bioaccumulation potential and low toxicity in comparison with conventional mineral oils to minimise environmental impact in the event of spillage or leakage.
  • Good oxidation and hydrolytic stability.
  • High shear stability.
  • Compatible with all common seal materials (Nitrile, Viton, HNBR) allowing simple replacement of mineral oil in hydraulic systems.
  • Exceeds the requirements of the Eaton-Vickers 35VQ25 pump test.

 

Available in: 20L, 208L drums

Castrol Transaqua HT - Water-based subsea production control fluid - 155DF1

Castrol Transaqua HT - Water-based subsea production control fluid - 155DF1

 

Castrol Transaqua™ HT is a water-based hydraulic control fluid specifically formulated for use as the control medium in subsea production control systems. The fluid incorporates all the features required for operation throughout the control system including Sub Surface Safety Valves (SSSV) and intelligent well completions. Transaqua HT has been developed and qualified under a Quality Management System with ISO 9001 Certification for Research and Development. Qualification testing carried out in accordance with ISO 13628-6 Annex C (2006 E) requirements.

 

Application:

  • Designed for use in all conventional and high pressure, high temperature applications (according to API 17 TR8).
  • Can operate over a temperature range of -30ºC (-22ºF) to 180ºC (356ºF).
  • Suitable for use within Electro-Hydraulic Multiplex (EH-Mux) or direct hydraulic control systems.
  • Designed for use throughout the entire production and workover control systems, covering Topsides and Subsea applications: both open water and well bore; and Downhole from control of a single SSSV through to complex intelligent well completions.

 

Advantages:

  • Tested according to OSPAR requirements. Rigorous environmental testing has also been completed in many geographies worldwide.
  • Contains a fluorescent leak tracer to allow rapid detection of subsea leaks either visually or using a dedicated ROV mountable leak detection sensor.
  • Maintains corrosion performance with seawater contamination.
  • Tolerant of the high well temperatures encountered by those parts of the control system located at the well bore.
  • Fully compatible and miscible in all proportions with other products in the Castrol Transaqua range and most other water-based subsea control fluids.
  • Compatible with a wide range of materials commonly used in subsea control systems (see Tables 3 & 4). More detailed compatibility information is available on request.
