Analysis and Preventive Measures of Offshore Steel Structure Welding Crack

Abstract:

In recent years, offshore oil & gas industry developed rapidly. Offshore steel structure is the support structure for offshore drilling and production platform, and its welding quality is particularly important in fabrication. This paper aims at the typical welding crack of offshore steel structure, through investigations and experimental analysis, considering the application characteristics of offshore steel structure and site issues, analysis the root causes of welding crack and give the improvement and prevention measures.
