Inspection of Airport Hydrant Systems | Applus+
INTRODUCTION

Airport hydrant systems must be regularly inspected for corrosion and the condition of their pipes assessed. The testing and pre-commissioning of jet-fuel pipeline systems for the aviation industry is a critical operation that must be carried out by specialist contractors to ensure a clean supply of fuel to aircraft.

THE Applus+ SOLUTION
Applus+ has developed customised technology for the inspection of airport hydrant system fuel lines, meaning that most of an airport’s difficult-to-inspect pipelines are now inspectable. These inspections provide quantitative data on the basis of which the asset owner can make sound decisions.
 
The Applus+ technology, involving pipeline inspection tools (PIT), ultrasonic techniques and corrosion mapping, is unmatched in terms of coverage, detectability and manoeuvrability to overcome common pipeline challenges, such as short-radius bends (1D back-to-back bend radius), unbarred full-bore offtakes and diameter changes. Thin-walled pipelines can also be measured, as this new technology can measure a remaining wall of just 1.5 mm thick.
By removing a flanged spool piece in the pipeline, such as a valve, the inspection system can be inserted and retrieved from the pipeline. With this service, our clients can assure the integrity of their hydrant systems without interfering with their day-to-day operations or requiring unwanted system shutdowns.
 
There are tailormade inspection systems available for each part of the hydrant fuel infrastructure. Following an inspection, the client will receive a report containing detailed information about dents, remaining wall thickness, damaged inner liners, etc.
 
These inspections can be performed regularly, following the inspection and maintenance programme, on all parts of the airport hydrant system with a view to ensuring safety, detecting and better understanding degradation processes and assessing the remaining life of the system.
TARGET CUSTOMERS
An airport hydrant system can be inspected at any stage of its life cycle.
 
Inspections involve the full lines running from the storage facilities to the manholes near the airport gates, including the following assets:
 
  • Risers
  • Piping vaults
  • Hydrant fuel lines
  • Jet fuel
  • Tank farms
  • Runways
  • Aprons
KEY CUSTOMER BENEFITS
By partnering with Applus+ for the inspection of their airport hydrant systems, our clients will benefit by:
 
  • Ensuring the safety of their systems
  • Detecting system degradation in a timely manner, thereby enabling targeted repair and maintenance work to be carried out and avoiding the need for full system replacement
  • Accurately assessing the remaining life of the system
  • Reducing system downtime and maintaining productivity, with the resultant cost savings
