ROSEN Automated Coiled Tubing Integrity Monitoring Service (ACIM)
Real-time feature detection during operations
Page last modified
May 21 2023
ROSEN’s ACIM is a sophisticated tool designed to identify critical defects before failure with a high probability of detection. It monitors the tubing condition in real time and provides a clear, unambiguous and comprehensive analysis of the inspection data in an easy-to-read report. Corrective actions can then be scheduled, thus increasing operational efficiency. The resultant inspection data can be used to inform risk-based integrity decisions and more realistic remaining life assessments. It can also be integrated with other data sources.
Pro/con
Confidence that coiled tubing is safe for operation
Accurate and reliable detection of metal loss and ovalities
Highly sensitive to even smallest defects, such as pinhole corrosion and mechanical damage
Real-time monitoring delivering immediate results on wall thickness, diameter, speed and depth
Designed for hazardous environments, including ATEX zone 1 for onshore and off shore operations
Cost savings and improved operating efficiency through avoidance of unscheduled downtime
Provision of vital input data for subsequent assessments, such as fatigue and remaining life assessments
Only works with magnetic materials like steel
