Background

NMDC was required to construct four oil islands at the Zakum site: two protected with Xbloc® units and two with ACCROPODE™ II units. CLAS inspectors provided full-time assistance to NMDC throughout the construction works.

ACCROPODE™ is a registered trademark belonging to the ARTELIA Group, and Xbloc® is a registered trademark belonging to DMC. These companies are in no way affiliated with CLAS.

Thanks to this total independence from license holders, CLAS was able to provide fully impartial expertise and certification, with no risk of conflict of interest. This neutrality made it possible to strictly apply our control methods, objectively assess placement quality, and ensure the reliability of the structures built on the Zakum islands.
