POWER GRID OPERATIONS

As a tradition, we are highly specialised in all types of operations linked with power grid operations. Whether it regards construction or power line inspection, we offer you the highest level of expertise.

HELICOPTER “HELI-BASKET” OPERATIONS

We have been using this method for over 30 years for cable repair operations, replacement of equipment such as bird tags.
All these operations are carried out with rapidity and safety. These operations have been carried out using Twin Star AS355N since 1994 and Super Puma since 2005. The AS 355N is currently being replaced by a H135 T3 for upgrading, improved safety and a wider capacity for intervention.

Technical side

The helicopter Heli-Baskets are suspended under our helicopters or hanged on the cables and enable two line-maintenance employees who are inside, to catch hold of the electrical cables and carry out their repairs or replacement of parts. The Heli-Baskets used under our Twin Star AS355N contain up to a maximum of 2 line-men.
The platforms used under our Super Puma H215 can carry up to a maximum of 4 line-men, and are used for the replacing of cable joining mechanisms or for operations at high altitude.
