Electrical Installations for the New Pipeline Between Geneva Airport (GVA) and the Vernier Oil Depots

SPIE MTS reference Feeder pipeline Vernier 2

Context & Description of Services

SPIE successfully completed electrical installation works at two SOGEP sites, as part of a power capacity upgrade and infrastructure modernization, in coordination with the operator and the energy distributor SIG. These interventions took place in explosive-risk environments, requiring tailor-made solutions and specific equipment to ensure the safety of the installations.

At the SOGEP 1 site, the services included:

  • SIG assistance for the modification of the MV/LV substation: Technical support to adjust the medium- and low-voltage substation to accommodate the power capacity increase.
  • Modifications to the LVMDB (Low Voltage Main Distribution Board): Update of the main low-voltage distribution board to meet new energy requirements.
  • Power supply and fiber optic network for a skid unit: Installation of the electrical and connectivity infrastructure required for the operation of the skid equipment.
  • Low-voltage system installation: Installation of fire detection systems, LIST cabling, emergency stop devices, and foam boxes to enhance site safety.
  • ATEX lighting: Installation of lighting compliant with ATEX standards, suited to explosive environments.

At the SOGEP 2 site, the works included:

  • Modifications to the LVMDB: Update of the equipment to ensure the stability and safety of the electrical installations.
  • Power supply and fiber optic network for a skid unit and a pig launcher/receiver station: Installation of a power supply tailored to the equipment's needs, in addition to the integration of a fiber optic network for reliable and fast communication.
  • Low-voltage system installation: Integration of fire safety systems, LIST cabling, emergency stop devices, and foam boxes.
  • ATEX lighting: Installation of ATEX-certified luminaires to meet the strict safety requirements in hazardous zones.

The Challenges

One of the major challenges of this project was carrying out the works within an explosive environment, imposing extremely strict safety standards. Furthermore, it was essential to minimize site shutdown times through close coordination with the operator, in order to ensure the continuity of operations.
