Over 400 transmitters for ConocoPhillips Ekofisk
Through Autek, their Norwegian representative Smar will supply more than 400 pressure and temperature transmitters to the Ekofisk 2/4M offshore platform in the North Sea, operated by ConocoPhillips
In the project, Smar supplied Profibus PA devices for the process automation solution.
A Profibus system is installed in the soy and multi oil refinery where the flow, acid and soybean dosing controls as well as the water, steam, level and temperature control are performed.
Smar provided pressure, level, flow transmitters (LD303) and temperature transmitter (TT303) as well as the positioners (FY303).
For control loops where 4-20mA transmitters were used, Smar provided their exclusive converters, IF303 (4-20mA converter to Profibus PA) and FI303 (Profibus PA converter to 4-20mA) to complete the integration.
All other manufacturers field devices are integrated, for example equipment from Siemens, P+F, Krohne and Metroval.
The system operates with a Siemens PLC (S7-400) and also with the ASI network from P+F.
The Profibus PA segment, containing the Smar devices, was configured using the Simatic PDM tool.
The new plant has been operating since September 2001.
"System interoperability and startup were excellent and the plant is operating very effectively.
The cost benefits and the simplicity of Profibus were confirmed and we are now using it for maintenance observations, which has been very useful" says the Cocamar automation engineer Jose Candido.
