Maldon, U.K. ICS Triplex has delivered its first U.K.-built turbine and compression control system to CNR International (CNRI). The Trusted T6300 system, built at the headquarters of ICS Triplex in Maldon, was completed in March 2008 and will be installed onto CNRIs Murchison platform in the North Sea during 2009. Once installed, it will monitor and control a gas-lift process that has been introduced to help increase oil production in the Murchison field.
The Trusted system has been built specifically to monitor the condition of the compressor and to control the start sequence and compressor loading process. It uses the unique SurgeGard system from ICS Triplex, which offers incipient surge detection and control. By detecting the rate at which the flow changes, SurgeGard can calculate a compressors proximity to surge and implement measures to prevent it from occurring.
Production began at the Murchison field in 1980, making it one of the most mature fields in the North Sea. Over time, as oil has been recovered, the cavity has lost pressure, which has caused oil production to slow. Injecting pressurised gas down the well will help increase the pressure and cause the oil to flow to the surface quicker, thus increasing oil production.
