The two new cutting-edge vessels will reinforce Prysmian’s submarine project execution capabilities and take its current fleet of six Prysmian’s current fleet of six state-of-the-art cable-laying vessels to eight.

Prysmian Group has announced an investment of approximately EUR 350 million for two new cable-laying vessels that will reinforce its submarine project execution capabilities.
The first cable-laying vessel will be an evolution of the Monna Lisa class. With a length of approximately 185 m and a breadth of about 34 m, the new vessel will be equipped with advanced cable installation solutions, such as three carousels for a total capacity of 19,000 tonnes, positioning itself among the highest cable loading capacity vessels in the market and enabling a reduced transportation time from the factory to the site, for an overall improved project efficiency.

A bollard pull in excess of 180 tonnes will allow the vessel to perform complex installation operations of simultaneous cable lay and burial (up to 4 cables) with a variety of ploughs, for an unrivalled optimisation of offshore operations. The vessel will be equipped with state-of-the-art DP3 positioning and seakeeping systems and will be operational by the beginning of 2027. As for Leonardo da Vinci and Monna Lisa, the new vessel will be built by the VARD Group (a subsidiary of the Fincantieri Group), one of the world leaders in the design and construction of specialised vessels for the offshore market.
The other vessel will be the evolution of the Ulisse class, with a length of approximately 167 m and a breadth of about 40 m and will be equipped by two carousels (one of them split in two concentric sections) for a total cable loading capacity of 10,000 tonnes. The state-of-the art DP2 positioning, and seakeeping systems and an eight-point mooring system will enable the ship to meet its operating requirements specialized in shallow-water cable laying and burial installation, even in harsh environmental conditions. The vessel will be operational by the first half of 2025.

Both vessels will have outstanding green credentials. They will be equipped with high-voltage shore connection systems to power them with clean energy during loading operations, diesel generators suitable for biodiesel blends and battery hybrid systems only for the deep-water-vessel, due to its specific activity.
Prysmian’s current fleet of six state-of-the-art vessels are the world’s most advanced cable-laying vessels, unrivalled for installation of long HVDC interconnections and in very deep water environments. It also has the widest range of high-tech burial equipment, including Hydroplows, HD3 Ploughs and Post Lay Burial machines (Sea Mole, SeaRex and Otter).
