In-Service Inspection
The in-service boiler or HRSG inspection has the advantage of being able to be conducted at nearly any time. It encompasses the external components of and typically refers to a unit that is running (or "hot"), but can also encompass a unit that is ready to run and in standby.
Boiler & HRSG Offline Inspections
The offline (or cold) inspection is an essential O&M activity at any thermal power or process plant. For steam generating equipment, whether it's a small industrial package boiler or a large utility-scale supercritical coal boiler, this is especially critical since only during a shutdown can the condition of all internal components be assessed in detail.
Borescope Inspection
The borescope is an essential tool for inspecting of power plant components. Commonly used in high-value rotating power-plant equipment such as steam turbines, gas turbines and generators it is also extremely useful for checking the internal or to reach external surfaces of boiler and HRSG tubes and piping.
Remote/Offsite Inspection Support
In the case where travel time or logistics prevent a Tetra inspector from being present on site, inspections can be conducted remotely in collaboration with client staff
Tuning of Control and Monitoring Systems
Improving or rectifying the operation of process control and monitoring systems in a thermal power plant is an important activity. This can entail both in-service and outage activities, and is an important corollary to an effective inspection program.
Welding Repair/Refurbishment Supervision
The quality of the thousands of factory and field welds present in the pressure part modules of a thermal power plant is critical for assuring long-term reliable operation.
Inspection Planning & Supervision
Tetra can provide experts to assist your staff in planning upcoming outages, as well as provide on-site supervision and surveillance to assure work quality and schedule.
Drone Inspection
As part of the Tetra Engineering inspection services, we offer remote visual assessments of your boiler/HRSGs using quadcopter drone technology
