Power Plant Turbine Outage & Turnaround Insulation Services
Advanced Thermal Corp. (ATC) delivers specialized, fast-response turbine outage insulation and turnkey outage insulation services for simple-cycle, combined-cycle, and steam generation power plants across North America. As a trusted turbine outage insulation contractor, we support planned turnarounds, Combustion Inspections (CI), Hot Gas Path (HGP) overhauls, Major Inspections, and emergency forced outages with precision replacement blankets and on-site technical support.
When unexpected insulation damage threatens your critical path, ATC eliminates schedule slip with emergency 24-to-48 hour custom insulation blanket fabrication, digital laser templating, and guaranteed drop-in OEM replacements. From heavy-frame gas turbines (GE 7F/9F, Siemens 501F) to aeroderivatives (LM6000, LM2500, LMS100) and high-pressure steam turbines, we ensure fast, safe, and compliant recommissioning.
Comprehensive Outage & Turnaround Insulation Capabilities
During power plant turnarounds, insulation is frequently the last discipline scheduled but the first to trigger critical path delays. Damaged, oil-soaked, or brittle blankets discovered during casing unbolting can halt reassembly. ATC provides end-to-end power plant outage insulation solutions engineered to protect outage timelines:
- Turbine Insulation Removal & Safe Laydown: Careful unlacing and systematic removal of blanket sets to prevent tearing or hardware loss. Blankets are inspected, cataloged, and organized on laydown racks for rapid reinstallation.
- Turbine Blanket Replacement & Upgrades: Direct replacement of damaged, water-logged, or oil-saturated OEM blankets with high-efficiency modern insulation cores (mechanically needled E-glass and silica aerogel composites).
- Turbine Insulation Field Measurement & 3D Scanning: Rapid on-site technician dispatch for precise field measurement and digital templating of modified piping, newly installed valves, or custom casing geometry.
- Emergency Turbine Insulation Fabrication: Rapid-response manufacturing facility in the USA capable of producing critical-path replacement blankets in 24 to 48 hours to keep your outage on schedule.
- Turbine Insulation Reinstallation & Final Certification: Certified reinstallation ensuring tight closure seams, proper spring tension, zero thermal bypass, and full compliance with OSHA touch-temperature thresholds (< 140°F).

Engineering Advantages of ATC Outage Insulation Services
Choosing Advanced Thermal Corp. as your dedicated turnkey turbine insulation partner delivers measurable operational and cost advantages:
- Permanently Stamped SS ID Tags: Every blanket piece features an embossed 316 stainless steel nameplate displaying equipment tag, section description, drawing reference, and sequential installation number for error-free laydown and reassembly.
- Quick-Release Fastening Systems: Heavy-duty stainless steel spring latches, lacing hooks, and high-temp D-rings allow blankets to be stripped in hours without damaging fabrics or cutting wires.
- Enhanced Thermal & Touch Safety: Designed to meet OSHA 1910.147 personnel protection guidelines (< 140°F / 60°C touch temp) and eliminate hot spots that degrade neighboring electrical cables, sensors, and actuators.
- Zero Asbestos / High Purity: All materials are 100% non-combustible (ASTM E136), free from asbestos, and non-hazardous to technicians during removal and handling.
