Domestic and foreign submarine cable market has broad prospects for development
The submarine cable market, both domestically and internationally, is showing significant growth potential. This trend is driven by a variety of key sectors that rely on these cables for power transmission and communication. Here are the main areas where submarine cables are in high demand:
1. **Coastal Cities and Island Markets**
China, with its vast coastline stretching over 18,000 kilometers and more than 6,000 islands, has a growing need for submarine cables to connect these regions. These cables play a crucial role in transmitting electricity and data between coastal cities and islands. In 2006, approximately 800 km of photovoltaic composite and cross-linked submarine cables were used, and by 2020, this demand is expected to exceed 3,000 km.
2. **Offshore Oil Platform Market**
Submarine cables are essential for offshore oil platforms, which require extensive cabling for power and communication systems. Different types of platforms use varying amounts of cable—self-elevating platforms need around 150 km, semi-submersible ones about 180 km, and oil production platforms up to 200 km. With China’s increasing offshore development, it's estimated that 13,000 km of various cables are used annually. About 15% of these are optoelectronic composite or power cables, totaling roughly 2,000 km per year.
3. **Underwater Cables for Rivers and Lakes**
As infrastructure projects expand, underwater cables are increasingly used in rivers, lakes, and reservoirs. Major waterways such as the Yangtze, Yellow, Nujiang, Qiantang, and Pearl Rivers are key areas of deployment. In 2006, about 300 km of submarine cables were used, and the demand is expected to grow significantly in the coming years.
4. **Offshore Wind Power and Transmission**
With onshore wind power reaching maturity, offshore wind energy is emerging as a promising new sector. Many countries are investing in offshore wind farms, and China is no exception. While onshore wind capacity reached about 2.6 million kW in 2006, the focus is now shifting to offshore projects. By 2020, it's projected that offshore wind capacity will reach 30 million kW, creating a strong demand for submarine cables in power generation and transmission.
5. **Southeast Asian and International Markets**
Countries in Southeast Asia, including Japan, South Korea, the Philippines, Malaysia, Indonesia, Vietnam, Thailand, and Myanmar, currently lack local submarine cable manufacturing capabilities. As a result, many projects import expensive cables from Western Europe. Chinese manufacturers, with their cost and regional advantages, are well-positioned to meet the growing demand. The market in neighboring countries is estimated at around 1,500 km.
In summary, the submarine cable market in China is highly promising, offering opportunities across multiple sectors. Companies should take advantage of this momentum to expand into coastal and island markets, offshore oil platform projects, offshore wind power, and international markets in Southeast Asia. With rising demand and favorable conditions, the future of submarine cables looks bright.
