Volker drills under cliffs for UK to France interconnector

NCE stock energy

VolkerTrenchless Solutions has started drilling before landfall connectors can be installed for the £271M IFA2 UK to France electricity interconnector project.

Volker is using a 250t drilling rig, which it has set up 100m in-shore, near the village of Chilling in the Solent. It will drill under cliffs and continue 650m out to sea.

IFA2 is a 1,000MW high voltage direct current electrical interconnector currently under construction for clients National Grid and RTE France.

The firm is also providing marine support for the installation of the polyethylene ducts to house the power cables. These ducts will be extruded in one continuous length for each of the six drillings.

VolkerTrenchless Solutions general manager Maurits van Balen Blanken said: “We are delighted to be working on such a prestigious project that will allow the flow of power between France and the UK. This project highlights our unique trenchless capabilities as a leader in the underground drilling market.”

Work is due to be completed next month, with the project completed in 2020.
