The MFS borescope inspection (BSI) is a method to assess the internal condition of a gas turbine without disassembly. Using a flexible camera probe, skilled engineers inspect critical components and create a detailed report with high‑quality visuals, enabling proactive maintenance planning and avoiding unnecessary downtime. A typical BI is scheduled every 4,000–8,000 operating hours or annually (whichever comes first) to maintain reliability and safety .

How It Works

A flexible tube with an integrated camera and LED lighting is inserted through an access port, allowing navigation inside tight, hard‑to‑reach areas of the turbine
High‑definition images or video are captured and stored for detailed inspection and documentation
Expert engineers analyze the visuals, detecting even microscopic defects, which are recorded with annotated photos in a formal BI report

Scope & Key Activities

Area Inspected	Typical Findings & Actions
Compressor blades & vanes	Fouling, cracks, impacts, damages, etc.
Combustion liners, fuel nozzles,	Detect cracks, hotspots, coating erosion, or deposits
Turbine blades & nozzles	Detect cracks, hotspots, coating erosion, or deposits and rub marks, blade tip wear, delamination or oxidization
Cooling holes & internal passages	Identify blockages, FOD or DOD that can affect airflow or heat control

Why It’s Valuable

Minimizes downtime: BSI avoids major disassembly so inspections can be performed quickly, often during shorter planned outages
Cost-effective diagnostics: Detect issues early to avoid expensive repairs or full component replacement
Enhanced safety: Remote inspection reduces risk of exposure to hazardous conditions and avoids unnecessary handling of hot components
Documentation and trending: Capture and archive images/video to track progressive wear and support condition-based maintenance decisions

Typical Frequency & Triggers

Scheduled routine: Every 4,000–8,000 equivalent operating hours or annually, whichever comes first, to prevent component degradation
Condition-based: Triggered by unusual performance trends. e.g. rising turbine temperature, increased fuel consumption, power loss, vibration spikes or following thermal excursions.
Emergency checks: Performed mid-shutdown or immediately post-event if suspected damage has occurred

Enhanced Features & Report

Detailed BSI report: Summarizes condition of inspected components, highlights anomalies, and contains annotated photos for each area inspected
Decision support: This visual evidence aids maintenance planning—helping determine if immediate repairs, scheduled attention, or full overhauls are needed
Enables field repairs or on-site engine exchange, backed by high-quality spare parts and repair documentation when required

Add-On Services (Optional) service agreement

A Long Term Service Agreement (LTSA), Maintenance Year Agreement (MYA), or Frame Work Agreement (FWA) with MFS ensures that your gas turbine is consistently maintained, expertly serviced, and always ready for operation — reducing downtime, controlling costs, and extending asset life.
