Installation of the world's deepest submarine power cable at a depth of two thousand meters

An Italian company managed to immortalize its name in the history of the electricity industry by installing an electric cable two thousand meters deep in the sea.

Eviralnews, citing Interesting Engineering, the Italian group “Prysmian” has completed the very deep installation of the submarine cable at a depth of 2,150 meters, which is a new record in this field.

Sea trials for this 500 kV High Voltage Direct Current (HVDC) sheathed mass cable, conducted by cable manufacturer and installation service provider Prismin, have also been successfully completed.

“This is a record-breaking installation in the power industry, as it is the first time an HVDC cable has been installed at such a depth, setting new standards for the market,” the company's statement said.

This installation is related to a new electricity corridor in the center of the Mediterranean Sea with a length of 970 km and a capacity of 1000 MW. The project, known as the “Tyrrhenian Link”, will connect Sicily to Sardinia and the Italian peninsula through a pair of underwater cables.

Deep sea cable innovation

This non-metallic armored cable, which is made using composite materials based on high modulus synthetic fibers (HMPE), is introduced as the next generation of transmission cable technology. HMPE is a type of fiber with low stretch ratio and high strength-to-weight ratio and resistant to erosion and wear.

The submarine cables of this project will be installed and maintained at a depth of more than two thousand meters of water, which is the deepest depth in which the electricity industry has ever installed a cable.

Cabling at such a depth is made possible by an innovative solution that can be 50% lighter than steel in water. This company has helped to realize this mission by using its advanced cable-laying ship “Leonardo da Vinci”.

According to the company, several laboratory tests have led to successful sea trials, which further demonstrated the reliability of Prysmin's technologies.

Prysmin's statement said: “In fact, this lightweight armed technology was used in 2019 for the connection between the Evia-Andros-Tinos regions at a depth of 550 meters and in 2020 for the submarine connection project of the Crete-Peloponnese regions at a depth of 1,000 meters. meter was used.

Increasing the capacity of renewable energy

The capacity of renewable energy is expected to quadruple by 2030, which shows the firm global trend towards decarbonization and energy transition. In the Italian cities of Sicily, Sardinia and especially Campania, we see a growing, significant and continuous generation of unscheduled renewable resources, such as solar and wind.

As a step in this direction, the €1.7 billion Tyrrhenian Link project is designed to increase electricity exchange capacity, boost renewable energy development and improve grid reliability.

Also, Prismin will strengthen the Mediterranean Energy Hub by designing, supplying and installing more than 1,500 kilometers of underwater cables to facilitate the exchange of electricity between Sardinia, Sicily and Campania.

In 2023, nine Mediterranean countries of the European Union, namely Croatia, Cyprus, France, Greece, Italy, Malta, Portugal, Slovenia and Spain, join hands to develop the Mediterranean region as a green energy hub.

The plan emphasizes marine renewable energy and new energy interconnections between the EU and non-EU Mediterranean countries with the aim of attracting investment in renewable energy and promoting sustainable energy solutions across the region.
