Successful overhaul at BP Rotterdam
During the scheduled shutdown at the BP refinery in Rotterdam at the end of 2011, Howden Thomassen Compressors (HTC) overhauled two C-25.2 reciprocating compressors.
The Thomassen Rsens™ system literally approaches rider ring monitoring from a different perspective. The system’s failsafe, solid-state sensor is mounted inside the cylinder head-end cover, where it enjoys a direct view of the piston. The probe is completely insensitive to contamination, and will endure the most gruelling operating conditions. It will also survive explosions, pressures in excess of 250 bara, corrosive chemicals and acid gases. All electronic components are located outside the cylinder, where they are easily accessed, even if the compressor is running.
The Rsens system has been extensively tested in simulated and production environments. Despite its ruggedness, the system is accurate to 0.1mm.
Further details are included in the Rsens brochure.
