CASTROL TRANSAQUA HT

Description

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 170ºC (338ºF).

Passed ISO 13628-6 Annex C (2006 E)/API 17F TR8 testing at 170°C (338°F)

-Track record of use in subsea production control systems at tempertures up to 170°C (338°F)

-Tested to 180°C (356°F) in SSSV Equipment to OTO 99 001

-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.

Care and Handling

This product has been manufactured to a tightly controlled cleanliness specification. Any container that has been

opened for use must be re-sealed to avoid contamination ingress from the environment (eg particulates or water). Any

contaminants entering the product can affect its performance. The integrity of the product once the container is opened

is the responsibility of the end user. It is good practice to use tarpaulins or drum lids to cover all containers to prevent

ingress of contamination.

As with all glycol based control fluids, CastroI Transaqua HT must never be mixed with control fluids of different base

types such as synthetic fluids (e.g. CastroI Brayco Micronic SV/3) or mineral oils (such as the CastroI Hyspin range).

Contamination of CastroI Transaqua HT by either of these types of products can seriously affect the product

performance.

If you need advice on any of the above, please contact your local Castrol Technical Service Engineer for more specific

details.

Storage

All containers should be stored under cover and protected from exposure to direct sunlight. Do not store containers in

temperatures below minus 5ºC or above 45°C. 208L plastic drums can be stored a maximum of 2 high, providing a

pallet is used to distribute the upper load evenly. In addition, the fill level of the upper drums should be less than or

equal to the fill level of the lower drums. It is not recommended to store 208L plastic drums horizontally.
