In 2025, my country's marine engineering and construction industry will achieve an added value of 211 billion yuan, a year-on-year increase of 0.3%

The Marine Consulting Center of the Ministry of Natural Resources released the "China Marine Engineering and Construction Industry Development Brief 2026" at the 2026 Xiamen International Ocean Week on the 7th, which showed that my country's marine engineering and construction industry will achieve an added value of 211 billion yuan in 2025, a year-on-year increase of 0.3% at constant prices. The industry is generally stable and the transformation continues to advance.

In 2025, the marine engineering and construction industry will develop steadily, with remarkable results in independent, green and intelligent transformation, and a large number of major marine engineering and construction projects will be implemented.

By region, the total added value of Zhejiang, Shandong, Fujian and Jiangsu provinces is approximately 159.7 billion yuan, accounting for approximately 76% of the country's total. Among them, the added value of Zhejiang and Shandong provinces is more than 45 billion yuan, accounting for more than 45% of the country's total.

From the perspective of key areas, there will be many breakthroughs and fruitful results in the construction of marine engineering construction projects in 2025. In the field of offshore oil and gas, a number of technological breakthroughs in 2025 will promote cost reduction and efficiency improvement in engineering construction. More than 30 jackets will be installed offshore, effectively ensuring energy supply. In the field of marine renewable energy, the newly installed capacity of offshore wind power has increased by more than 60% year-on-year, and the project layout continues to expand into the deep sea; the large-scale utilization of tidal energy has started a leap from megawatt-level demonstration to hundreds of megawatt-level large-scale. In the field of marine transportation, the Shantou Bay Undersea Tunnel of the Shantou-Shantou High-speed Railway, the world's first single-hole, double-track high-speed rail undersea tunnel with a design speed of 350 kilometers per hour, was successfully completed. In the field of seawater desalination and comprehensive utilization, breakthroughs have been made in the application of secondary seawater circulation cooling technology for nuclear power plants.

In 2025, the development of my country's marine engineering and construction industry chain will achieve remarkable results. It has cultivated a number of leading market entities, and the localization level of key offshore equipment has continued to improve. Its construction capabilities in cross-sea bridges and tunnels, offshore wind power, ports, offshore oil and gas development and other fields have ranked first in the world.

Facing the future, my country's marine engineering and construction industry will closely adhere to the main lines of independence, greenness, and intelligence, continue to tackle core technologies, improve supporting industrial chains, coordinate industrial development and marine ecological protection, and provide strong support for the construction of a maritime power.
