Siemens V84 Repair & Service Capabilities

Our full-scope MRO services for Siemens V84 gas turbines address the full lifecycle—from rotor overhauls to combustion upgrades and hot gas path restoration. Every service is supported by our integrated engineering team and quality-controlled shop processes.

Rotating Components: Restore Balance, Extend Life

Rotating equipment endures extreme thermal and mechanical stress over every operating cycle. Our process begins with a full teardown and diagnostic review, targeting wear, imbalance, and fatigue before they escalate into forced outages. With specialized tooling and exacting standards, we bring rotors and flow path parts back to optimal condition.

Services include:

Rotor disassembly, inspection, and precision-controlled rebuild
Blade, vane, and ring segment requalification or replacement
Dynamic balancing to eliminate vibration and improve efficiency

Combustion System Performance & Emissions Tuning

Efficient combustion is the backbone of turbine reliability. We inspect and upgrade Siemens V84 combustion hardware to ensure flame stability, reduce pressure pulsations, and maintain emissions compliance—even in aging systems. Our upgrades often outperform OEM specs in durability and environmental control.

What we deliver:

Comprehensive inspection and tuning of burners, liners, and transitions
Hardware replacement or repair with enhanced materials
Seal upgrades and part realignment for reduced blow-by and wear

Static Component Repair with Structural Precision

Casing and diaphragm misalignment, cracks, or distortion can lead to serious downstream damage. We restore structural integrity through controlled welding, re-machining, and realignment—ensuring tight clearances, smooth flow paths, and long-term operational confidence.

Repairs include:

Weld repair and machining of diaphragms and casing assemblies
Sealing surface restoration and geometry correction
Pre-assembly inspections for thermal and mechanical fit

Data-Driven Documentation, Diagnostics & Part Recovery

For many operators of legacy Siemens turbines, part availability and documentation gaps are major obstacles. We solve both with advanced reverse engineering and comprehensive repair records—helping you manage lifecycle risk, validate repairs, and plan long-term.

Key offerings:

Reverse engineering of discontinued or unsupported parts
Full NDE, runout analysis, and dimensional inspection
QA and lifecycle tracking tailored to your O&M documentation needs
