Leonardo da Vinci is a DP3 cable laying vessel built for Prysmian Group by Vard, with hull construction at Vard Tulcea and final outfitting at Vard Brattvaag in Brattvåg, Norway. The vessel was delivered in August 2021 and has since joined Prysmian’s fleet as a core asset for submarine cable installation projects, with ownership and operation both held by Prysmian Group. Technically, Leonardo da Vinci features very large 7,000- and 10,000-tonne cable carousels, DP3 station-keeping, and hybrid power with battery systems, giving it high bollard pull and long endurance suitable for deep-water installations down to 3,000 metres. Its class notation reflects extensive comfort, automation, environmental, and battery-power notations, indicating a modern, highly redundant cable-laying platform. In the market, Prysmian deploys Leonardo da Vinci primarily on high-voltage subsea interconnectors and offshore wind export cables worldwide, where its high cable load capacity and speed help reduce the number of installation campaigns and transit legs, improving project schedules and reducing emissions compared with older cable layers.

Propulsion & Power
Propulsion Typehybrid
Propulsion System
Hybrid diesel-electric propulsion with six Wärtsilä diesel generator engines feeding three aft Azipod azimuth thrusters, two forward retractable azimuth thrusters and two bow tunnel thrusters. Power is supplemented by two battery-based Energy Storage Systems used for peak shaving and energy regeneration from cable-laying equipment, enabling reduced fuel consumption, emissions and DP3 station-keeping capability.
Engine Type6 Wärtsilä hybrid propulsion diesel generator engines (4 × ~4,500 kW and 2 × ~1,440 kW)
Number of Engines6
Total Power21,000 kW
Generator Power21 MW
Emissions ClassIMO Tier III
Environmental NotationRINA GREEN PLUS; comfort notations COMF-NOISE CREW A, COMF-VIB CREW C, COMF-AIR; Battery Powered (2 × 750 kWh)
DP ClassDP3
Max Speed16 knots
Bollard Pull200 t
Battery Capacity1,500 kWh
Hybrid System
Hybrid power system consisting of 6 diesel generators and 2 battery Energy Storage Systems (2 × 750 kWh). The ESS provide peak shaving and can store regenerated energy from the cable-laying equipment, allowing reduced generator use, lower fuel consumption, and significantly reduced NOx emissions.
Thrusters
3x azimuth (aft Azipod) (3.2 MW each)
2x retractable azimuth (forward) (2.4 MW each)
2x bow tunnel (2.5 MW each)
