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.
Sandro Esposito, global marketing manager for digital products, said: “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.
“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.”
Dresser Masoneilan’s SVI II ESD is a new technology in emergency shutdown valve automation and in-service valve partial stroke testing. The device can be implemented using a 4/20mA signal (analog safety demand), 0-24Vdc (discrete safety demand) or a combination of both.
