Forensic and Legal

When things go wrong there may be an opportunity to find out why and learn. Forensic studies are designed to improve our engineering understanding of the problem and so avoid them in the future. We have been involved in forensic studies to explain unexpected jackup leg penetration, pipeline uplift during backfilling, and many trenching-related issues.

Senior staff in Cathie Associates also act as experts and expert witnesses in their own area of expertise in legal cases. Dr David Cathie has particular experience with acting for trenching contractors in respect of claims for unforeseen ground conditions or when expected trenching performance was not achieved. The expert must be rigorous and independent while at the same time representing the interests of his client or his client’s legal team.
