With the development of petroleum industry in China，undersea oil and gas development has gradually extended from shallow of the continental shelf to deep waters，therefore， high strength and high toughness and excellent resistance to lamellar tearing are the properties which heavy-gauge offshore platform steel must have in the future. This paper presents the research progress on high performance offshore platform steel at home and abroad in recent years，and the key technical problems of such steel production also be mentioned. Research work and engineering applications of high- strength plates in The State Key Laboratory of Rolling and Automation，such as Ultra Fast Cooling（UFC）and γ+α quenching technique，are finally reviewed.
