This paper aims to provide an insight into submarine power cable while differentiating it from a power cable used on land. Though there are several issues (such as complex and unclear regulations, few consulting firms to conduct sea floor surveys and availability of cable-laying ships) that could impede the growth of submarine power cables, under-construction and future projects due to the increasing demand for renewal energy from offshore energy sources are ensuring that the necessary expansion, diversification, development and use of these cables cannot be stopped. Rising energy prices and concerns about climate change in the mid-2000s brought about a forced development of deep-water renewal energy sources (such as wind, wave, tide, etc.) which in turn renewed the interest in submarine power cables as there was a need to transmit the generated power to land from out-in-the-ocean renewal energy installations. Though these cables have been in use since the early 1800s, their use was primarily limited to transmitting electricity from conventional sources such as coal plants, either between countries or out to islands or oil platforms. The data in this map were provided by EMODnet human activities.Submarine power cables are specialised power cables that are used to transport electric current at high voltage below the surface of water. ![]() ![]() Click on one of the cables to learn more about its type, length, capacity, when it was installed and who maintains it. The map of the week features a schematic representation of the submarine communication cables that cross European waters. Submarine telecommunication cable networks cost billions to install 1 and need constant monitoring and repair, as they may be broken or damaged by trawl fishing, anchors, earthquakes, submarine landslides and even shark bites 2. However, this capacity comes at a significant price. These fibre-optic cables have the capacity to transmit data at a staggering 200 terabits per second 1, which vastly outpaces today’s satellite radio transmission (around 1 gigabits per second), making them the preferred means of communication. While these early cables consisted of insulated copper wires, which were simply dropped on the seabed, current generation submarine cables consist of optical fibres covered by many protective layers buried in the seafloor 2. ![]() Submarine cables have a long history starting with the first commercial submarine telegraph cable in the English Channel in 1850, closely followed by the first transatlantic cable in 1866 1. With over 99% of international internet and telephone traffic passing through submarine telecommunication cables 1, they are a vital though often forgotten part of today’s digital society. Whenever you access a website hosted on a foreign server, chances are high that the information you are receiving travelled through the depths of the ocean.
