Parker supplies valve to oil platform

A Parker Hannifin - Parker Sales UK product story
Edited by the Engineeringtalk editorial team Oct 23, 2008

Parker Instrumentation has supplied a custom compact double block and bleed valve to reduce the size and weight of a skid for the Chevron Tahiti platform in the Gulf of Mexico.

Built by Test Automation and Controls, the chemical injection skid is designed to operate at 1,034 bar to withstand the pressures required for operations in the Tahiti field's deep, sub-salt reservoirs.

Parker's integrated valve provides a 1,034 bar-rated double block and bleed function.

At this operating pressure, such valve configurations are usually constructed using discrete components - involving a large amount of space, extensive weight, and a large number of potential leak paths.

The number of components is often made higher because the cone and thread interfaces used to make connections at these pressures are usually fitted with an additional anti-vibration accessory, to combat the common issue of vibration-induced problems associated with threaded connections.

To simplify the project, Parker Instrumentation suggested an uprated version of its single-piece, 690 bar double block and bleed manifold, fitted with the company's 1,034 bar-rated MPI compression tubes.

The resulting manifold is estimated to reduce the mounting space and weight budgets by around 50 per cent, and replaces around nine individual components (three valves and six anti-vibration glands), greatly reducing potential leak paths.
