New Installation capabilities for Submarine Cables


Installation capabilities

Our extensive track record means our knowledge of how to carry out a submarine cable installation is second to none – we make the best use of the available resources to ensure project efficiency and safety at all times. However challenging the conditions. From shallow water to deep water, from soft soils to hard soils, from single cable to bundled cables, we have the experience and assets to provide complete solutions across all manner of cable installations.

Largest state-of-the-art vessels fleet in the industry

Prysmian fields five of the most state-of-the-art cable-laying vessels in the world. They offer extended project versatility with deep-water installation capabilities of up to 3,000 m, as well as shallow-water and near-shore solutions

Monna Lisa: from genius to masterpiece, the new vessel is coming to life

We are thrilled to announce the name of Prysmian Group's forthcoming cable-laying vessel: "Monna Lisa"! Inspired by Leonardo da Vinci's unparalleled masterpiece, this iconic name perfectly embodies the essence of our new addition to the fleet. Just like the enigmatic smile of the renowned Monna Lisa painting, our vessel represents a fusion of elegance, innovation, and ingenuity. As we set sail towards the future of undersea connectivity, we are proud to pay homage to one of the greatest artistic achievements in history.
