Dresser Masoneilan will supply SVI II ESD analog safety demand units for integration into the Yokogawa Pro-Safe-RS safety instrumented system and Yokogawa PRM asset management suite.

"Project engineers wanted a solution that provides continuous diagnostics during a safety trip, enables partial stroke testing of the emergency shutdown valves at regular intervals and withstands the harsh offshore environment," said Sandro Esposito, global marketing manager for digital products. "The SVI II ESD is the only SIL3 smart ESD that remains live during and after a shutdown, capturing shutdown events as a full-proof test, allowing continuous HART® communications during a trip and providing local panel annunciation using the built-in discrete outputs. In addition, partial stroke testing functions are provided on a single wire pair, reducing installation costs, and SIL3-certified stainless steel housing ensures its durability."

DRESSER MASONEILAN HAS been named the emergency shutdown device (ESD) supplier for BP's floating production, storage and offloading (FPSO) vessel in the Plutao, Saturno, Venus and Marte oil fields off the coast of Angola, Africa.
