Dr Annette Karstensen, Senior Structural Integrity Consultant

Annette is a Chartered Engineer with more than 14 years experience in structural integrity assessments. These assessments cover engineering components related to power and petrochemical plants and other engineering plants. Her main line of work involves the application of assessment procedures to calculate maximum tolerable flaw sizes and/or time-to-failure under cyclic load. Assessments are also typically carried out in connection with fitness for service investigations or failure investigations involving corrosion, fracture, creep and/or fatigue.

Having previously spent 7 years at TWI (formerly The Welding Institute) in the UK , Annette has achieved an in-depth knowledge of assessments, particularly related to welds, using BS7910 " Guide on methods for assessing the acceptability of flaws in metallic structures". Annette is also familiar with other assessment procedures such as API579, R5 and R6. Annette also is extensively involved in recommendations with regards to mechanical testing programmes such as fracture toughness testing and measurement of welding residual stresses.

Annette has extensive experience in finite element stress analysis (FEA) and has analysed a large range of both linear and non-linear components (plasticity, thermal and contact). FEA in structural integrity is typically carried out to determine stress intensity factor solutions and/or applied stresses for input into the engineering critical assessment. She has also extensive experience in performing corrosion assessments using FEA and has published several papers on the subject.
