The objective of the activity was to obtain more information concerning the implementation of the dewatering system, and the analyses and model tests underpinning the need to reinstate dewatering as a constructional measure.

We also wished to perform spot checks of non-conformity handling, the analysis base and Shell's quality assurance of analyses, tests and acceptability assessments of non-conformities.


Non-conformities were identified in connection with:

  • Verifications
  • Fatigue analyses
  • Non-conformity handling

In addition, an improvement point was identified in connection with wave-load calculations.
