Today, let us know about steel for ships and marine engineering
. Since ancient times, the determination of mankind to conquer the sea has never wavered, but in the actual action, it is the continuous exploration and expansion of marine resources. On February 13, 2017, the world's most advanced ultra-deepwater double-drilling tower semi-submersible drilling rig "Blue Whale No. 1" was named and delivered in Yantai. Its overall steel consumption is about 40,000 tons, of which 10% is super-strong and ultra-thick steel. "Blue Whale No. 1" is the first "turnkey" project of China's shipyard in the ultra-deep water field of marine engineering, which is a milestone.
As a key structural material for offshore engineering equipment, steel is widely used in drilling platforms, production platforms, and submarine pipelines. Due to the long service life, it is necessary to resist the harsh wind and wave conditions for a long time. The cost of underwater repair and maintenance is extremely high. The DH36 ship steel plate used for it gradually has high strength, high toughness, easy weldability, good corrosion resistance, large thickness and large Standardization direction development. Today, let us know about steel for ships and marine engineering.
