Prysmian’s new cable-lay vessel has taken a further step towards completion with the hull now fully completed, including the entire superstructure and the launching ceremony completed
The vessel, Leonardo da Vinci, is shortly to be towed to Vard’s shipyard in Brattvåg, Norway, for final fitting out, installation of cable-laying equipment and finishing, all of which has been designed, manufactured and supplied directly by Prysmian.
The new vessel was designed to provide an especially high level of flexibility, and to be able to install cables in deep water of more than 3,000 m when required. It has two carousels, one of 7,000 tonnes capacity and one of 10,000 tonnes.
The vessel will have two independent laying lines to increase its operative flexibility and a bollard pull of in excess of 180 tonnes, conferring the ability to undertake simultaneous laying and cable burial, supporting a variety of burial machines such as heavy-duty ploughs and the company’s Hydroplow.
In addition, it will be equipped with a DP3 dynamic positioning system. The propulsion system is designed to reduce the ship’s environmental footprint.
Designed to be able to undertake bundled cable laying in addition to simultaneous laying and burial, the new vessel has a length of approximately 172 m, a beam of 34 m and accommodation for 120 people.
With a speed in transit of in excess of 14 knots, Leonardo da Vinci has a hybrid propulsion system with six diesel generators and two battery-based energy storage systems, each of 750 kW, providing the vessel with a total of 21 MW.
The battery power will assist with peak shaving, when energy demands on the vessel are high, and will help to reduce fuel consumption.
