Comments of our people involved

“The MOG project was the first 220kV submarine cable turnkey project of this size for Hellenic Cables and a major milestone in its growth.

A high-profile job with very demanding time schedule and unforeseen circumstances, such as the use of repair joints, was delivered in outstanding quality, well ahead of schedule and below budget.”
