It was initially applied to the North Sea region, but can be used in other regions as well, taking into account local conditions such as temperatures.

Steel for offshore platforms

An offshore platform is a special place where operations are carried out on the ocean. The service life of the offshore platform is 50% higher than that of the ship, and the steel plate used must have high strength, high toughness, fatigue resistance, lamellar tear resistance, good weldability and seawater corrosion resistance. It is mainly divided into two categories: drilling platform and production platform. 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

, API API2H-50, BS7191 350EM, E36; 420 main grades: En10225 S420, API AP12Y-60, ship mark E40, E420; The main grades of 460 class: S460 of EN10225 and E460 of ship mark.
