Offshore Wind Accelerator: Fatigue Resistance of Ground-Flush Welds by NDT and FM

Calling for entries from companies and consortia interested in undertaking a study for the OWA Foundations Technical Working Group (TWG-F) that will investigate the fatigue resistance of ground-flush welds by NDT and FM.

The main objectives of this work are to establish if the output information and statistics from Non-Destructive Testing (NDT) of ground-flush welds can be used to define fabricator specific S-N curves.

Furthermore, this project aims to demonstrate, by Fracture Mechanics (FM) or another similar method, the dependence of S-N curves on the size, location, and concentration of defects within ground-flush welds.

The deadline for clarification questions is 24 May 2022 at 12:00 BST.

The closing date to receive tender submissions is 1 July 2022 at 12:00 BST.

All clarification questions and tender submissions should be sent electronically, by their respective deadlines, to with in copy.
