Is it for me?

Structural, civil, maintenance, pipeline, materials, welding, inspection and plant engineers including those responsible for maintaining welded equipment and structures, managing the integrity of ageing structures and optimizing asset performance.

Key features of the course:

  • Introduces the concepts of fitness-for-purpose and engineering critical assessment (ECA), using a mixture of lectures, informal discussion, quizzes, videos and software exercises to reinforce learning
  • Focuses on the practical applications of fracture mechanics and covers brittle and ductile fracture, plastic collapse, fatigue crack growth and stress corrosion cracking
  • Highlights fracture and fatigue procedures in BS 7910, with an emphasis on how they are applied to welded structures
  • Discusses the assessment of circumferential flaws in pipeline girth welds
  • Covers a range of relevant subjects related to BS 7910, e.g. failure case studies, non-destructive testing (inspection), materials properties, fracture toughness testing
  • Provides practical training in fracture and fatigue assessments using CrackWISE software
  • Provides engineers with a firm foundation in the application of BS 7910 to the assessment of flaws using fitness-for-purpose methods

What else should I know?

All venues:
  • This course is given by specialists highly experienced in the development of BS 7910 and in the practical application of fitness-for-purpose methods to a wide range of applications including pressure vessels, pipelines, offshore structures, vehicles, bridges and buildings
  • Training time is typically from 0900-1630, including coffee/tea and lunch breaks, with an earlier finish (approx. 1500) on the final day
  • Participants receive a full set of course notes and a Certificate of Attendance
  • Temporary CrackWISE licenses are provided to participants to allow them to install and use the software immediately before, during and after the training course; participants are therefore requested to bring laptop computers to the course, with the software installed
