The design and assessment of jacket tubular joints are usually performed based on the stress-lifetime (S-N) curve in Chinese ocean oil and gas engineering projects, while the fracture mechanics methods are rarely employed. This article describes the basic theory of fracture mechanics, ECA, fatigue crack growth law and general assessment procedure, and then gives an assessment example by JPEFA program.

Key words: ocean oil and gas engineering, tubular joint, fatigue assessment, fracture mechanics, ECA
