Submarine Power

OVERVIEW

Linking worldwide progress to global power

As a world leader in the energy and telecom cables and systems industry, we can play a crucial role in the global energy transition.

From underground cable systems that support the energy transition and power wind farms to submarine systems, we work on supply-only and turnkey projects for some of the world’s largest operators. The Group has supplied several of the major underground and submarine links, as well as submarine cable connections for the main offshore wind farms, both fixed and floating, by using specific technologies for undersea power transmission and distribution with sophisticated solutions that satisfy the strictest international standards.

Our commitment to the energy transition

The transition from fossil fuels to renewable energy requires an efficient, smart, and robust energy grid to meet the special challenges of managing these discontinuous power sources. Interconnectors are an increasingly important part of power grids, allowing for connections between countries and even continents to ease the flow of affordable and clean energy across long distances. They are a key part of the energy transition: supporting the implementation of a larger, more integrated, efficient and sustainable power transmission system. Prysmian’s submarine interconnectors are made of new, lighter materials and can go deeper under the sea than ever before. Our high-voltage underground interconnectors can bring power more efficiently over long distances from where the energy is produced (like offshore wind farms) to where energy is consumed.

An Innovation leader

Prysmian is an innovation leader in both high-voltage submarine and underground cable system. For underground power transmission, we have designed new ±525 kV HVDC cable systems, qualified with P-Laser and XLPE insulation, with a higher voltage capacity and with large conductor cross-sections to provide optimal technical solutions for more efficient, reliable and eco-friendly power transmission over long distances.

In addition, our Research and Development labs have created a submarine cable with new synthetic armour which can be up to 50% lighter than others, enabling Prysmian to perform ultra-deep installations or up to 3,000 meters in marine ecosystems previously considered impossible.

Our commitment to Offshore Wind Farms

Renewable energy resources are abundant and inexhaustible. One of the Prysmian commitments is to invest in Offshore Wind applications, that are fundamental in meeting the increasing demand for greener energy.

Undisputed world leader in the provision of HV underground & Submarine Transmission cables

We’re the strategic partners for our TSO customers, supporting the development and production of transmission grids, and helping to facilitate the bulk movement of electrical energy from the site of generation to electrical substations. Making innovation a cornerstone of our work, and R&D a constant investment, we offer both HVAC and HVDC cable systems for power transmission for both land and submarine connections.

But we deliver so much more… following the integration of General Cable into the Prysmian, we can now call on the strength of NSW and its longstanding expertise in fibre-optic submarine cables, accessories and solutions.

German HVDC cable projects

Prysmian is the undisputed leader in high voltage land cable systems and solutions we are playing a key role in developing three vital German HVDC cable projects that will contribute to achieving decarbonization goals. To do so, the Group will develop smart and sustainable power grid infrastructures to support the energy transition in Germany and Europe.

So we’re now better placed than ever to work in close partnership world-leading network operators as they look to establish the next generation of communications infrastructure. Fundamentally, our customers require products and solutions that offer the lowest possible environmental impact and the highest added value – along with uncompromising safety and reliability. And that’s exactly what we provide.

Submarine Telecoms Solutions

The transmission of data and communications has long stretched beyond the confines of the land. In response to an ever-growing requirement for telecommunications to be transmitted across oceans, Prysmian has expanded its reach to once again become a world leader.
With the acquisition of General Cable, the Group added the capability and services of Norddeutsche Seekabelwerke GmbH (NSW) to its portfolio

OUR MARKETS

Network Components

Applying years of experience, Prysmian offers a complete range of accessories for all types of energy cable. This is backed by specialist engineering services to help you fulfill any power system requirement or specification.

OUR MARKETS

Power From Shore

The offshore production of oil and gas plays a vital role in the energy infrastructure of many countries.

OUR MARKETS

Asset Monitoring Systems

In HV & Submarine power transmission grids cable systems represent a high-value asset to be preserved and each non-transmitted MW is a financial loss factor.
