Abstract
Risk based approach to assess structural integrity and life of pressure vessel has been presented, starring from EU PED 2014/68 and API 581, ending with use of basic fracture mechanics parameters. In the scope of risk matrix, structural integrity has been tackled by use of the Failure Assessment Diagram (FAD), while structural life was assessed by means of Paris law, using fatigue crack growth rate as relevant parameter. Several case studies have been provided to illustrate this comprehensive approach, including penstock and air storage tanks in Reversable Hydro Power Plant, and two spherical storage tanks, one for vinyl chloride monomer (VCM), the other for ammonia. Besides the assessment of integrity and life, including some important issue like over-pressurizing, roles of engineers and managers in this process is defined and explained.
