DURAPIPE UK PROVIDES DRINKING WATER FOR OIL RIG WORKERS

Posted: Friday 30th January 2009

Durapipe UK pipework and fittings form the basis of a reverse osmosis desalination plant that will be installed on an oil platform in the North Sea.

The plant has been manufactured by Salt Separation Services, a leader in designing, manufacturing and installing water treatment systems, and uses the reverse osmosis technology to convert seawater into potable water. As a result, Durapipe ABS pipework and fittings up to 2”, TKD and VKD manual and actuated ball valves and MK manual and actuated diaphragm valves were selected for all low pressure seawater piping and potable water piping during the pre-filtration and post treatment processes.

The project required complex criteria to be met, as one system needs to cater for two very different water solutions. The corrosive nature of seawater means the pipework needs to be fully resistant to this type of attack; the high performance properties of Durapipe ABS material ensures that all of the pipework and valves remain totally corrosion resistant over the lifetime of the system.

Secondly, for the conveyance of potable water, the water needs to remain uncontaminated and safe to drink; the smooth bore of Durapipe ABS, combined with its corrosion resistance, inhibits the formation of scale, ensuring that the system stays clean throughout its life. Futhermore, in order to reassure customers of its use for drinking water, Durapipe ABS pipe and fittings are fully WRAS (Water Regulatory Approval Services) approved and the system is listed in the “List of Approved Products” published by the DWI (Drinking Water Inspectorate).

In addition to providing a high performance product for conveying the solutions, Durapipe ABS also offered Salt Separation Services significant cost savings; at 1/6th weight of steel, the material is much easier to handle on site and coupled with its simple jointing technique, offers reduced labour time and costs.

Commenting on the use of Durapipe ABS, George Haworth, Production Manager at Salt Separation Services said: “We had very specific requirements for this project; it was imperative that the chosen pipework and valve system could convey both seawater and potable water without compromising performance on either. I firmly believe Durapipe ABS is the best product on the market to achieve this.

“The purpose of our plant is to produce safe drinking water so the fact that Durapipe ABS has key water regulatory approvals was a key factor in the decision making process for us.”

The new plant is capable of producing 40,000 litres of potable water from seawater per day and has recently been installed on a new oil platform stationed in the North Sea.

Durapipe ABS offers installers and end users a variety of benefits; its corrosion free properties and wide temperature capabilities make it the ideal system to carry a variety of low temperature fluids. The lightweight material and ease of jointing with Durapipe ABS also makes it a quick and easy solution to install, offering significant installation cost savings.
