On-Stream Support

On-stream support refers to any support activities, including inspection and maintenance, that take place in a facility while the facility or equipment is in continuous operation. Sentinel Integrity Solutions has the personnel and equipment to provide comprehensive on-stream support services to operators in the refining and petrochemical industries. We can conduct on-stream inspections of various types of equipment, including several different types of on-stream storage tank inspection. We supply experienced resident API and NDE inspectors who can provide continuous on-stream support for facility personnel. Sentinel Integrity provides AutoCAD assistance to help operators plan on-stream activities. We are also able to provide on-stream quality assurance solutions, ranging from QA consulting services to QA personnel to run the program for you.
