Abstract: ［Objective/Significance］Offshore oil platforms are subjected to prolonged exposure tocomplex and severe marine corrosive environments，with the splash zone experiencing particularlyaggressive corrosion. Such corrosion can compromise the structural integrity of steel components，lead to pipeline failures，and potentially trigger significant safety and environmental incidents. Effectiveprotection of steel structures in the splash zone is therefore critical to ensuring the operational safety ofoffshore oil platforms.［Analysis/Discussion/Progress］This study provides a comprehensive review ofprevalent corrosion protection technologies for steel structures in the splash zone，encompassingmetallic coatings，metal or alloy sheathing，heavy-duty anti-corrosion coatings，composite cladding， and viscoelastic materials. A comparative evaluation is conducted based on criteria such as long-termprotective efficacy，construction efficiency，and economic viability. Metallic coatings and metal or alloy sheathing exhibit superior protective performance but entail high costs and complex applicationprocesses. Heavy-duty anti-corrosion coatings offer ease of application and cost-effectiveness，yet their impact resistance is limited. Composite cladding demonstrates excellent corrosion resistance andimpact durability but is characterized by lower construction efficiency and higher costs. Viscoelasticmaterials provide high application efficiency and reduced costs but are constrained by limited impactresistance.［Conclusion/Prospect］ Each technology presents distinct advantages and limitations， necessitating careful selection based on site-specific requirements. As marine oil and gas explorationintensifies，there is an urgent need to develop advanced corrosion protection technologies for the splashzone that combine long-term durability，enhanced impact resistance，high construction efficiency，and optimal cost-effectiveness.
