As a critical component of infrastructure that facilitates the development of marine resources, energy production, and scientific research, offshore platforms are frequently subjected to various hazards, including structural corrosion and connection failures, which arise from the challenging conditions of marine environments. In extreme cases, these issues can lead to significant production accidents and financial losses. This article begins by outlining the background of corrosion affecting offshore platforms. It subsequently discusses the different types of corrosion and their underlying causes in detail, concluding that these platforms primarily encounter several forms of corrosion, including electrochemical corrosion, microbial corrosion, and stress corrosion, with electrochemical corrosion being the most prevalent. From a phenomenological standpoint, corrosion can be categorized into localized corrosion and uniform corrosion. The article further elaborates on various anti-corrosion technologies, encompassing the selection of corrosion-resistant materials, electrochemical protection methods, and coating protection strategies. The principal conclusions drawn indicate that stainless steel, titanium alloys, and specialized corrosion-resistant alloys are commonly employed in offshore platforms. Additionally, the efficacy of the sacrificial anode method is significantly influenced by temperature. The external current method proves advantageous for the anti-corrosion of large structures, while organic coatings, such as epoxy coatings, and inorganic coatings, including zinc-rich coatings, are also discussed. This article offers a systematic and comprehensive perspective, serving as a technical reference for anti-corrosion research related to offshore platforms.
