Cardiff Airport: Powering Fuel Operations Without Disruption
From overnight shutdown windows to live apron operations under Welsh skies, Meson keeps Cardiff Airport’s fuel infrastructure safe, compliant, and ready for the next departure.
PART ONE
From Compliance Works to Complete Fuel Infrastructure Delivery
Meson’s work at Cardiff Airport has developed through sustained involvement in the fuel farm moving from inspection and compliance-led works into full system installation and control.
The relationship began with hazardous area inspection, testing, and targeted repairs, delivered safely within a live fuel environment. Over successive inspection cycles, Meson became a trusted partner for fuel farm electrical integrity, earthing assurance, and safety-critical fault resolution.
As confidence grew, Meson was engaged to deliver more complex, integrated works, including the installation of a complete fuel storage tank and associated electrical and control systems.
Across the site, Meson has delivered:
Annual and periodic hazardous area inspection & testing
Full fuel tank installation, including power, instrumentation, and control panels
Hazardous area inspection, testing, and repairs (2024 & 2025)
Fuel farm monitored earthing installations and upgrades
Investigation and rectification of system alarms & faults
Defuel tank overfill prevention control systems
Tank & control system relocation works
External lighting and tank floodlighting repairs
These works collectively support the safe storage, transfer, and management of aviation fuel in a continuously operating airside environment.

PART TWO
Tank Installation and Control Systems in a Live Fuel Farm
The installation of a relocated fuel storage tank represented a step change in scope moving beyond inspection and maintenance into full system delivery.
Meson was responsible for the electrical and control infrastructure supporting the new tank, including:
Design and installation of control panels for tank monitoring and protection
Integration of level measurement, alarms, and safety interlocks
Power distribution and earthing for the new installation
Interface with existing fuel farm systems to ensure coherent operation
All works were delivered within an ATEX-classified environment, requiring:
Strict control of ignition sources and equipment selection
Coordinated shutdowns and tie-ins to avoid disruption to fuel operations
Structured testing and commissioning to confirm system integrity before handover
The control panels were designed to provide clear operational status, reliable alarm indication, and fail-safe behaviour, supporting both day-to-day operations and abnormal event management.

PART THREE
Earthing Integrity, Monitoring, and Ongoing Assurance
With additional tanks and systems introduced, earthing integrity becomes increasingly critical.
Meson installed and maintained monitored earthing units across the fuel farm, providing continuous verification that earth paths remain intact not just compliant at the point of installation, but over time.
This approach allows:
Early identification of degraded earth connections
Prevention of static discharge risk in hazardous zones
Increased confidence in alarm and protection systems
Reduced likelihood of unplanned operational restrictions
Safe Delivery, Proven Capability
Through inspection, installation, and control system delivery, Meson has supported Cardiff Airport’s fuel operations with infrastructure that is:
Safe in hazardous environments
Operationally integrated with existing systems
Compliant and auditable
Designed for long-term maintainability
The relationship continues through ongoing inspection, testing, fault response, and improvement works built on calm delivery, technical competence, and trust in live airside environments.
