Submarine Cables Overview

A submarine cable, also known as an undersea cable or submarine communications cable, is a type of cable laid on the ocean floor to transmit data, telecommunications signals, and sometimes electricity between different countries or continents.

Submarine cables are typically constructed with multiple layers of protective materials. The core consists of fiber-optic strands that carry the data, surrounded by layers of insulation, and protective sheathing to withstand the harsh marine environment. Submarine cables can vary in length, ranging from a few hundred kilometers to thousands of kilometers. They can span vast distances across oceans, connecting countries and continents. Submarine cables have a significant data capacity, with some modern cables capable of carrying multiple terabits of data per second.

Global Submarine Cables Market Share, by Application, 2022

The submarine power cables sub-segment accounted for the highest share in 2022. The global shift towards renewable energy sources, such as offshore wind farms, has driven the demand for submarine power cables. These cables are used to transmit electricity from offshore renewable energy installations to onshore power grids. As countries invest in renewable energy projects to reduce carbon emissions and increase energy security, the demand for submarine power cables increases. Countries and regions are increasingly establishing power interconnections through submarine power cables to share electricity and optimize energy resources. These interconnections help stabilize the power supply, facilitate energy trading, and enhance grid resilience. Many islands and remote coastal areas rely on submarine power cables to connect to the mainland power grids. This electrification process aims to improve energy access and economic development in such regions.

Global Submarine Cables Market Share, by Voltage, 2022

The high voltage cables sub-segment accounted for the highest share in 2022. High voltage cables can transmit power over long distances with lower energy losses compared to medium and extra high voltage cables. As voltage increases, the current decreases for the same power transfer, reducing resistive losses along the cable. Transmitting power at higher voltages permits more effective power transmission. This is important for long-distance power transmission. Although high-voltage cables require more insulation and specialized equipment, the reduced energy losses and the ability to transmit larger amounts of power over long distances make them more cost-effective in the long run, particularly for large-scale power transmission projects. High-voltage cables can transmit the same amount of power as lower-voltage cables using smaller conductor sizes. This means less material is required for construction, making the cables more lightweight and easier to handle during installation.

Global Submarine Cables Market Share, by End-User, 2022

The offshore wind power generation sub-segment accounted for the highest share in 2022. Offshore wind farms are located far from the coast in open waters where traditional overhead power lines are not practical. Submarine cables can efficiently transmit electricity over long distances underwater, connecting remote wind farms to the onshore electrical grid. Submarine cables help minimize the environmental impact of power transmission. Unlike overhead power lines, which require significant land use and disrupt sensitive ecosystems, submarine cables have minimal visual impact and do not interfere with land activities. Submarine cables enable the integration of power from various renewable energy projects, ensuring a more balanced and reliable power supply. Offshore wind farms can be connected to the onshore electrical grid through submarine cables, allowing the generated electricity to be distributed to consumers and industries effectively. Submarine cables offer scalability for offshore wind projects. As wind farms grow in capacity, additional cables can be installed to accommodate increased power generation. Submarine cables can be routed around natural obstacles or shipping lanes, allowing wind farms to be located in optimal areas with favorable wind conditions.
