Abstract
AS2885 considers pipeline girth weld defect acceptance using and Tier Tier 1 (workmanship standards) 2 (fitness for purpose) and by Engineering Critical Assessment (ECA) as Tier 3. However, ECA is currently an unwieldy tool and unattractive to those who have only an occasional need to carry out assessment using fracture mechanics. A road map is described for the development of an ECA defect acceptance methodology. Input parameters to an ECA are also reviewed. The early stages in the evolution of an expert system, which aims to make the ECA route more accessible to the pipeline industry, are described.
