HART bus underpins OrmenLange predictive maintenance

HART Communications and Emerson AMS Suite cited as key enablers of state of the art diagnostics system.

StatoilHydro’s Ormen Lange Norwegian gas field was highlighted as a state-of-the-art deployment of the HART communications standard at the annual PowerGen show in New Orleans this month. HART is a bi-directional protocol for communicating between intelligent field instruments and host systems.


Emerson’s AMS Suite of diagnostic software applications and field devices was cited as the key enabler in StatoilHydro’s predictive diagnostics program on Ormen Lange’s subsea installations, onshore terminal and the world’s longest subsea gas pipeline. The network delivers diagnostics from 350 continuously monitored digital valve controllers, elements of Emerson’s PlantWeb digital plant architecture.


Craig Llewellyn, president of Emerson’s Asset Optimization said, ‘StatoilHydro worked creatively with Emerson to execute its vision for predictive maintenance in an open architecture, maximizing asset availability and performance.’ StatoilHydro was awarded the 2007 HART ‘Plant of the Year’ for Ormen Lange. HART Foundation members include Emerson, GE, Invensys, Honeywell, Siemens, Toshiba and Yokogawa. 20 million HART-enabled devices are installed world-wide.
