Helifuel System Design and Manufacture :

We are leading experts in the design, build and manufacture of helicopter refuelling packages for rental or purchase.

Harran refuelling systems are developed to ensure that only clean, uncontaminated, and water-free fuel is delivered to the aircraft with maximum safety.

The standard Harran refuelling system refuels aircraft of all types by the over-wing, or under-wing refuelling method. Derivatives based on this well-proven system are manufactured to suit particular requirements, for example, on offshore installations the system can be tailored to suit space and weight constraints, deck elevation and available utilities etc.

Safety systems including fire detection/protection and/or Jettison arrangements are available according to requirements.

All refuelling systems and equipment are fully compliant to the internationally recognised offshore guidance standard UK CAA CAP 437.  Systems can be built and configured to each customer's project requirements. 

Our approach has always been to deliver the highest level of technical expertise combined with reliability and excellent customer service.  Harran provides full project support during all stages of any work scope along with onsite commissioning of the helicopter refuelling system by a highly-skilled and competent Harran systems engineer, at any global location.
