Abstract Scope Jack-up racks for wind turbine tower installation vessels require stronger teeth to withstand the enhanced wear caused by the higher frequency of up and down operations compared to classical exploration O&G drilling rigs. That is why design of WTIV is upscaled up to 10'' thick racks instead of the standard 7” gauge used for drilling platforms. Offshore structural steel with a nominal yield strength of 690 MPa is the reference material of choice in this application. Maintaining the same material performance while increasing the section is not a simple task. The same or better mechanical properties shall be guaranteed for the whole thickness and the material characteristics in terms of processing and welding must be qualified. This paper will highlight the experimental characterization of 8 and 10'' thick base metal plates the industrially produced by Industeel technological production facility in France. The SAW weld metal properties will be presented too.
