Radar level measurement upgrade on FPSO vessel

August 1st, 2012, Published in Articles: EngineerIT

BP Exploration has replaced unreliable level transmitters previously used on a floating production, storage and off-loading (FPSO) vessel with guided wave radar (GWR) transmitters from Emerson Process Management. The more accurate and reliable level readings from Emerson’s Rosemount 5300 series GWR transmitters have helped BP Exploration increase safety, reduce shutdowns and increase production. Operating 160 km off the west coast of Africa, the BP FPSO processes and stores oil production for export. At 310 m in length, it has an oil storage capacity of 1,77-million barrels and can process up to 240 000 barrels per day. Changing process conditions and the presence of foam and vapour, as well as dirty sticky fluids, made this a difficult application for measuring levels. BP Exploration worked with Emerson to replace existing GWR units with Rosemount 5300 GWRs. With Emerson’s advanced signal-processing technology that ensures detection of low dielectric fluids, the Rosemount GWR is able to send and receive a cleaner, stronger signal. This allows the use of single-lead probes that increase tolerance to solids build-up and coating, and eliminates trips due to false readings.
