In‑Situ Rotor Thermal Straightening

Dimensional survey and root cause analysis for permanently bowed rotors, delivered via specialised thermal heating processes, in‑process measurement and correction, combined with dynamic balancing and operational verification.

Rotor Journal Laser Cladding & Restoration

Addresses damage including scratches, grooves, eccentric wear and out‑of‑roundness; restores original dimensions through NDT, cladding, on‑site machining and precision grinding.

Turbine Blade Repair & In‑Situ Replacement

Repair welding, cladding, profile surveying, custom fabrication, heat treatment, installation and balance verification for erosion, cracking, distortion and fracture defects.

Precision Rotor Dynamic Balancing

Vibration testing, spectrum analysis, unbalance location, balance weight calculation, and low‑speed / high‑speed dynamic balancing services.

Casing, Diaphragm, Seal & Stationary Component Restoration

Repair and precision restoration for joint faces, diaphragm distortion, seals, sliding keys and other stationary components.

Flow‑Path Efficiency & Life Extension

Optimisation of flow‑path clearances, seals, blade and casing conditions to reduce steam leakage and flow‑path energy losses.

Precision Shot Cleaning

Deep cleaning of fouling and corrosion on rotors, diaphragms and blades to restore surface condition and flow‑path performance.

NDT, Dimensional Verification, Alignment & Commissioning

Inspection, quality documentation, shaft alignment, reassembly and trial operation, all integrated into a complete closed‑loop repair process.
