A new type of manifold developed by Parker Instrumentation is helping to save weight and space on BHP Billiton Petroleum’s Angostura offshore platforms. The design re-engineers the “monoflange” double-block-and-bleed manifold concept to accommodate two instrument connections instead of one. From a single flange interface to the piping or processing vessel, the new manifold provides connections for both a local visual gauge and an electronic transmitter that connects to the remote control room – each with its own double-block-and-bleed isolation valves. Parker’s twin-monoflange manifold was developed to combat the severe space and weight restrictions on satellite wellhead platforms, following a suggestion from the facilities engineering contractor for BHP Billiton’s Angostura development, Technip Offshore Engineering of Houston. Parker’s new component integrates all the discrete valves and tube fittings for process pipe to two instruments into a single assembly.
