Tyco supplies valve manifolds to Kazak oil field

Tyco Valves and Controls, a business unit of Tyco Engineered Products and Services, has supplied 500 valve manifolds to a USD3.5billion project at the world's deepest super-giant oil field

Tyco Valves and Controls, a business unit of Tyco Engineered Products and Services, has supplied 500 valve manifolds to a USD3.5billion project at the world's deepest super-giant oil field.

The Anderson Greenwood standard and high pressure Monoflange units have been provided for the TengizChevroil (TCO) Second Generation (SGP) and Sour Gas Injection (SGI) projects at the Tengiz oil field, located onshore at the edge of the Caspian Sea in western Kazakhstan.

Applications include double block and bleed instrument isolation, gauge isolation, instrument drain, chemical injection connection and direct or remote mounting of instruments.

The Monoflanges, specified by contractors PFD UK Ltd, were produced in a 5-valve design, with double block, double vent and single outlet characteristics.

Constructed from Alloy 625, the units have a 10,000 psi working pressure, and are built to low emissions specification.

High pressure units will come into contact with sour gas, containing hydrogen sulphide concentrations at 18percent.

All of the supplied equipment is capable of withstanding the variable Kazak ambient temperatures ranging from -40C in winter to +40C in summer.

The one-piece ultra-slimline Monoflange combines a compact design with the benefits of fewer potential leakpaths and reduced height, weight and installation costs, in comparison with conventional designs.

It is designed to provide high mechanical strength with long cycle life on primary isolation duties.

The SGI project will utilise state-of-the-art technology to enhance oil recovery.

Sour gas will be injected into the oil reservoir to maintain pressures within, enabling TCO to recover more crude oil for export, along the Caspian Pipeline.

By early 2007, when SGI and SGP projects are fully on line, oil production at Tengiz will increase from 13 million tonnes to approximately 25 million tonnes annually, and will similarly raise production of gas, LPG, and sulphur saleable products.

The field currently produces 2-3billion cubic metres of associated gas per year.

The Tengiz field is operated by TengizChevroil, a partnership between ChevronTexaco, ExxonMobil, KazMunaiGaz, and LUKArco.

Anderson Greenwood Instrumentation products are available from Tyco Valves and Controls, the leading name in manufacture and supply of valves, actuators and controls.
