Background

The Port Gardian breakwater, originally built with natural rock armour, had suffered significant damage requiring complete reconstruction.
The ACCROPODE™ II block was selected for the new armour layer. The contractor BUESA was awarded the contract and called upon the expertise of CLAS to provide full-time support.

ACCROPODE™ is a registered trademark owned by the ARTELIA Group and is in no way affiliated with CLAS. CLAS intervened in addition to CLI, within the framework of a license agreement signed between CLI and BUESA.

The independent expertise of CLAS enabled BUESA to implement the installation and inspection procedures best suited to the project.

Role of CLAS

The mission entrusted to CLAS:

  • safety training, which is not provided by the license vendor,

  • training of personnel in block installation methods,

  • supervision of armour block placement,

  • preparation of the quality assurance file for EGIS.

Result

The objectives set were achieved despite difficult weather conditions.
The structure was protected within two months and delivered on schedule, without reservations.

Without the presence of CLAS on this site, the contractor could have been forced to reconstruct parts of the structure that were in fact fully compliant.

This project demonstrates CLAS’s ability to guarantee quality, safety, and speed of execution on complex maritime construction sites.

It is essential to be supported by a company such as CLAS, with the procedures, tools, resources, and field experience required to defuse negative opinions when they are unfounded, while also being able to identify genuine non-conformities when they exist, in order to prevent future failures.
