Application Overview

CLEO

is suitable for use across a wide range of subsea hydraulic applications with its core design application towards use as a subsea production control fluid in both open (discharge to sea) and closed (return) systems.

CLEO

is designed to operate in subsea production control systems across a temperature range of -45°C and +250°C, making it suitable for both Ultra HP/HT and more conventional subsea projects.

CLEO

is also capable of operation in a host of other subsea applications including its use as an Umbilical Storage Fluids, wellhead preservation fluid , and as a general low viscosity hydraulic oil.

Please use the hyperlinks above for further information on the most common applications for CLEO outside of subsea production control systems or contact us for further information.

Qualification Database

 

We are pleased to introduce the new CLEO Database.

 

CLEO Environmental Oil based Fluid has been extensively tested and qualified across a wide range of subsea equipment to industry standards.

 

To showcase this sheer level of qualification information, OEO has developed a bespoke, user friendly database to create a platform from which to investigate the qualification status and performance characteristics of the fluid across a wide range of equipment types, materials and conditions. For a summary of the qualification areas involved please see the ‘Key Features’ tab.

Environmental Oil Based Subsea Control Fluid

CLEO

is a fully functional subsea control fluid with a wide operational temperature range between -45°C to 250°C and is qualified across a wide range of industry equipment and to industry standards. CLEO also boasts a massive compatibility dataset in relation to metals and elastomers commonly used in subsea systems.

 

This low viscosity environmental oil demonstrates excellent lubricity/anti-wear, corrosion protection, freeze protection, hydrate protection, stability and all round technical performance.

 

CLEO

is environmentally acceptable for use in OSPARCOM countries, boasting a 'Yellow' status for use in Norway and an OCNS Class E for use in UK waters. CLEO is also tested annually under the GOM GMG290000-2012 permit with excellent ecotox results.

Topside Environmental Oils
For Topside systems the main product portfolio is designed around our EO (Environmental Oil) range comprising different ISO viscosity grades such as EO08, EO12, EO18, EO32, EO68, EO100, EO150 and EO220.

This product range is designed to replace mineral oils across a wide range of topside hydraulic systems and offers customers an OCNS Class E (UK) and Yellow 1 (Norwegian) Environmental profile.
Subsea  Control Fluids
CLEO is an Environmental Oil based subsea production control fluid capable of operation between -45°C and +250°C and is designed for super high temperature/high pressure wells and closed loop systems utilising a return line to platform.

HDEO Range fluids are High Density, Environmental Oil based Subsea Actuator Fluids, designed for applications where a specific gravity greater than seawater is required.
CLEO Environmental Oil
CLEO is a High Temperature Environmental Oil based Subsea Control Fluid. It was developed to bridge the technology gap between water based fluids and the extreme HP/HT developments of the future, by providing a very stable high temperature fluid capable of maintaining temperatures in excess of 250°C for a project lifetime.

In addition, with the potential future requirements for closed loop systems in some sectors this environmental oil is not only acceptable for direct discharge to sea, but is designed to offer all the properties of traditional oil based fluids in closed loop systems.
