Crondall Energy have taken the lead role in independent verification process, reviewing the post-installation condition of the replacement and new flowlines.


The objective of the verification role was to ensure that the design approach on replacement and new flowlines for Quad 204 development is technically robust. The post-installation verification included assessment of the design robustness and review flowlines as-laid and predicted conditions. Crondall Energy’s expertise were applied to assess flowlines buckling and embedment to analyse span rectification impact on buckling and walking response of the flowlines. Crondall Energy also continued Quad 204 support with review and analysis of the survey data from the operating system.
