Late 2013 saw the publication of a new edition of the long-standing flaw assessment procedure BS 7910 ("Guide to methods for assessing the acceptability of flaws in metallic structures"). TWI has been associated with this British Standard, which allows users to set flaw acceptance criteria and sentence flaws found during service or fabrication using fracture mechanics calculations, since its inception In 1980 as document PD 6493.
The new edition introduces several significant changes with respect to the earlier (2005) edition, so TWI is running a series of four-day training courses around the world to introduce the standard to both new and existing users. The most recent of these was held in Kuala Lumpur in March, and attracted a range of participants from the oil, gas and power industries. The course, run jointly in Malaysia by Ian Partridge of TWI SE Asia and Isabel Hadley of TWI Ltd, uses a mixture of lectures, informal discussion, videos, hand calculations, quizzes and software examples to reinforce learning.
Attendees of the Malaysia course had the following comments:
Interesting session for the use of CRACKWISE to tackle and solve the case problems - Mohamad Lutfi bin Samsudin, Malakoff Power Berhad
The course is presented in an easy to understand and clear way. Tutorials and examples given are helpful and at appropriate level for better understanding of the ECA and Crackwise - Toh Chin Kok, SBM Offshore Malaysia
Further courses are already scheduled for Houston and Abington and are available on request in other parts of the world.
