PART TWO

Delivering Quality

The project included the supply, build and installation of a GRP-mounted electrical control arrangement, complete with main switchgear, distribution, protection and emergency stop systems.

Meson delivered the full electrical installation across the fuel area, including sub-main power supply, containment systems and cabling to dispensers and associated equipment. A TT earthing system was installed, including earth rods, earth bar and full bonding to tanks and equipment.

Emergency stop systems, a fireman’s switch arrangement and local test facilities were installed to ensure safe isolation and ongoing compliance. The works concluded with full testing, commissioning and certification, including hazardous area inspection documentation.

The Solution

Meson began the project by building the GRP control enclosure off-site at our workshop. This allowed the main switchgear, distribution equipment and safety controls to be fully assembled and checked before arriving on site, reducing installation time and improving overall quality.

Once on site, the GRP enclosure was positioned and connected to a new sub-main supply from the existing distribution board within the building. This formed the central point for power distribution across the fuel installation.

From there, the installation was built out across the site alongside the mechanical works being carried out by Octane Holding Group, who were responsible for the tanks, dispensers and fuel equipment setup. As the installation progressed, containment routes were installed where required, and cabling was run to each element of the system, ensuring everything was connected and coordinated correctly.

The works were carried out within an active airfield environment, with helicopter movements and training operations continuing nearby. This required careful coordination and a controlled approach to installation to ensure all works were completed safely without impacting ongoing site activities.

A key focus throughout the works was the implementation of clear and reliable safety systems. Emergency stop stations and a fireman’s switch arrangement were installed to allow rapid isolation of the system if required, with local reset functionality to safely bring the system back online.

Earthing and bonding were also critical elements of the installation. A full TT earthing system was installed, with earth rods, earth bar and bonding connections to all tanks and equipment to ensure safe dissipation of fault currents and static build-up.

The final stage of the project was commissioning. Meson worked on site alongside the project team and the airfield fire chief, ensuring the system was fully tested and, importantly, that those responsible for operating it understood how it functioned.
