Recently, China Geological Survey under the Ministry of Land and Resources announced in the South China Sea that our country finished the pilot production of a kind of superior energy (flammable ice) in the South China Sea. Our country thereby was the first to realize stable exploitation of marine superior energy in the world. “Now we dare to pat our chest to say that our material helped our country with creating the first in the world” said the personnel from Ansteel Ocean Engineering Steel Production and Sales Team who participated in the material supply for the project.

F550 ultra-thick steel plate is an ultra-high strength ocean engineering steel which is custom-made by Ansteel for the platform. The plate is a top-class product among ocean engineering steel which can fully meet the application requirements of offshore platform working in all the seas throughout the world. At present, Ansteel is the sole steel manufacturer inChinato have the qualification for supplying this steel grade. F series ultra-high strength ocean engineering steel supplied by Ansteel this time is mainly used for connecting the double bottom of upper platform and column for “Blue Whale I” offshore platform. The part is the most critical part for the platform and also the part with the most stress and most serious fatigue in the whole platform. Using this material can efficiently ensure the service life and safe work of the platform. Meanwhile the platform has big weight and deep working depth. In order to prevent fatigue cracks in the welding part due to long-time utilization and ensure the safety and reliability of platform operation, Ansteel Ocean Engineering Steel Production, Sales and Research Team did CTOD performance inspection for the supplied plate. It can efficiently prevent plate crack extension and slow down the crack extension speed to increase double protection for the platform safety.

Ansteel Ocean Engineering Steel has been devoting itself to the cutting-edge research in steel materials, keeping promote Chinese steel industry progress, and meanwhile provide strong support in material for downstream manufacturing industry--------in 2014, ship plate from Ansteel was used for the icebreaker with the first independent design and building in China; in 2016, crack arrest steel developed and produced by Ansteel was supplied for the largest container ship in our country-------It is incumbent on Ansteel to build the pillars of a great power with its material.
