Coupling Pipes

OVERVIEW

We understand the importance of interconnectors and the need for technically suitable and highly reliable cable solutions for a sustainable exchange and integration of energy in the electricity supply of the respective countries and in the broader development of regional energy transmission infrastructures.

We deliver comprehensive and fully managed EPCI projects with solutions for interconnector cable systems, using our extensive engineering, production and turnkey installation capabilities, applying a complete project management approach and providing the required cost-effective high-power current cable connections.

Prysmian is a leader in the interconnector sector and is pushing technological boundaries to be able to offer optimized performance and economically efficient HVDC cable systems to our customers who are developing, expanding and renewing their power grids.

We offer an extensive and leading HVDC portfolio with the largest product range to meet these needs. We offer MI and MI-PPL paper-insulated solutions and extrusion cables with both P-Laser and XLPE insulation systems.

For us, innovation is an endless process, which is also evident from our current activities that are aimed at raising voltage levels. We are currently developing an 800 kV P-Laser capacity as a complement to our current 600 kV solutions.

In other areas, we are busy optimizing systems and methods to produce cable connections for even greater water depths, up to 3,000 meters.

The benefits of Prysmian

One of our greatest strengths is that we can offer our customers a comprehensive package.

With our end-to-end service and deployment of our extensive portfolio of manufacturing, installation, and engineering capabilities, including our fleet of leading cable-laying vessels, we are a single-source supplier that offers complete EPCI turnkey cable system solutions to meet the needs of our customers.

We differentiate ourselves with our complete value chain. Our customers have a single point of contact with us where they can always turn to for all their project needs.

Why coupling pipes?

Interconnections offer economic benefits by extracting energy at a lower cost in one country and being redirected to another and increasing efficiency in the use of generated power through the balance of supply and demand in larger geographical areas. These interconnectors increase the security of supply of electrical energy to specific countries and can contribute to promoting the integration and development of renewable energyas in the case of regional development of offshore wind farms that can be located at a fairly large distance from the centres of demand.

Prysmian in action

We are market leaders in the application of interconnectors and have played a central role in most projects in this field worldwide.

 

Undersea

  • Western Link. From design and production to installation, testing and commissioning, Prysmian provides a complete turnkey service for the HDVC connection between Scotland and England. The offshore installation was carried out by our own cable-laying vessel, the Giulio Verne.
  • North Sea Link (NSL). The NSL connects Norway to the UK and with a total route length of 740 km, the NSL is the longest undersea HDVC cable connection ever built. Prysmian supplies and installs a total of approximately 950 km of undersea and land cables for this prestigious project.

 

Land

  • INELFE: Electrical connection between France and Spain INELFE has been designated as a 'priority project' by the EU and has a number of key milestones to its name. It is the HVDC land system with the highest power (2 GW) and highest voltage (± 320 kV) that uses an extrusion cable connection that is ready for commercial use. Very long cable lengths were used for our turnkey cable system (about twice as long as the industry average), which significantly reduced the project execution time and risks.
  • Italy-France connection. The start of this project is scheduled for 2019 and Prysmian will be responsible for the design, delivery, installation and commissioning of the system.
