Growth Factors

The submarine cable industry is primarily driven by rising offshore wind farm investments, rising data traffic, and expenditures made by OTT providers to meet demand. Many uses for power and communication employ submarine cables. They are frequently used for power transmission to oil rigs, power from offshore wind farms to power plants, and links between nations and islands. The need for low-power cables is being influenced by the rising need for linking the power systems of various nations.

Submarine communication cables are used for international contact between countries and regions. Submarine cables are responsible for 97% of all global internet traffic, and as internet usage grows, the demand for cables is also expected to surge. Global market expansion has been fueled by the increasing focus on integrating offshore renewable energy sources and greater energy security. These communication cables facilitate quicker communication and transmit a lot of data around the world.

Segmental Overview

The market for Submarine Cable is segmented into the offering, application, voltage, and end-user. Based on application, in 2021, the submarine power cable market accounted for 60% of total revenue. The market for submarine power cables is driven by rising inter-country and island connectivity needs and new capacity additions in the offshore wind sector. Additionally, the need for submarine power cables has increased due to increased research and development efforts brought on by the growth of offshore wind farms and the electrification of offshore oil and gas networks.

Based on offering, with more than 35% share of the market, the installation & commissioning segment led the market in 2021. This is brought on by the high price, necessary technological processes, and installation equipment. Undersea cable vessels, jointing and testing tools, operation management software, and underwater installation tools are all parts of the equipment used to deliver submarine cables.

Underwater robot remotely operated vehicles, beach burying equipment, burial machines, and an automatic control system make up the underwater installation equipment for submarine optical cables. Over the forecast period, this market is anticipated to offer potential growth possibilities.

Regional Overview

In 2021, the Asia Pacific region held the most significant market share. The approval and deployment of wind farms are at their highest levels in this area, with China dominating the market. Direct investments in the construction of submarine cable infrastructure are increasingly concentrated in the Asia-Pacific region. Google, Microsoft, and Facebook are the main players in the region. For instance, Google has already purchased the Asia-based undersea cable market. Additionally, Google invested in the new subsea cable system that was deployed to connect Australia and Japan via Guam in 2021.
