At present, the main grades of steel used in international offshore platforms are 355,420,460MPa, and the main grades of 355 are: S355 of En10225, API2H-50 of API, 350EM of BS7191, and E36 of ship mark; The main grades of 420 grade: S420 of En10225, API2Y-60 of API, E40 and E420 of ship mark; The main grades of 460 class: S460 of EN10225, E460 of ship mark. There is no special steel standard for offshore platforms in China, and foreign standards are adopted. The steel used for the platform below EH36 has basically been localized, accounting for 90% of the steel used in the platform, but the large-thickness and high-strength steel used in key parts still relies on imports. With the continuous development of China's marine development, the demand for steel for offshore platforms continues to expand, and the current total steel consumption is more than 3 million tons.
