CLAS HAS ESTABLISHED A CLASSIFICATION OF BREAKWATERS USING ARTIFICIAL BLOCKS
TYPE ACCROPODE™, ACCROPODE™II, CORELOC™, ECOPODE™, XBLOC®, BS1, BS2, BS3 AND OTHERS
CLASS A
These are structures built with the blocks ACCROPODE ™, ACCROPODE™II, CORELOC ™, ECOPODE ™, XBLOC ® , BS1, BS2, BS3, or others, to the service life conforming to the design objectives or more.
These are the zero risk works built under the certification that we apply at the
request of the master work or business.
CLAS regularly intervenes as a "third part".
These works benefit from the complete monitoring of the construction of the underlayment and its support in mats of feet, by a diving inspector accredited by CLAS.

All our inspectors are IMCA and HSE approved professional divers. As such, they can go to all construction sites without exception, including offshore installations, and really check the reality of the work carried out.
ZAKUM ISLAND ABU DHABI KUANTAN en Malaisie.
CLAS inspectors also work out of the water and all have a drone for real-time construction monitoring.
Based on the TECHNOLOGY COMPLIANCE reports established by CLAS inspectors, the TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™ CORELOC ™ , X-bloc® , BS1, BS2, BS3, or other shells can be approved without reservation as conforming to the design and technology and validated CLASS A shells. They comply with the mark which only concerns CLASS A structures for which each block TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™, X-bloc ® , BS1, BS2, BS3, placed has been inspected and recognized as conforming to the technology.
CLASS A shells built with TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™, X-bloc ® , BS1, BS2, BS3, or other blocks must be monitored every five years and after exceptional storms. To date, the CLASS A shells built under the supervision of CLAS inspectors have not had to undergo any maintenance or repair operation.
CLASS B
These are structures built with the blocks ACCROPODE™, ACCROPODE™II, CORELOC™, ECOPODE™, XBLOC ® and others, whose durability is not guaranteed due to an unknown part of the quality of the construction or non-conformities level 2 unrepaired and/or approval given based on company surveys and follow-up without inspectors divers accredited by CLAS.
Appraisals of works built without the supervision of CLAS inspectors have shown non-conformities that do not appear not in as-built documents and site logs. Except in extreme cases, the direct consequences of these nonconformities are very difficult to assess and in particular the date of occurrence of the damage. These shells TETRAPODE, ACCROPODE ™, ACCROPODE™II, ECOPODE ™, CORELOC ™ and X-bloc ® should be considered potentially more fragile than expected and should be subject to increased monitoring.
The construction aid tools, which are mistakenly given the virtue of inspection and approval tools, do not make it possible to highlight all the non-conformities. The same applies to acoustic tools such as multibeams and acoustic cameras.
We have tested and evaluated the most accurate and modern acoustic tools. The IMCA and HSE approved professional diver qualifications of the CLAS inspectors allow them to dive to compare the reality of the construction with the computer-generated images produced by these tools. This gives CLAS a considerable advantage and a more refined knowledge of these tools and their limits. Thus we have shown that there is a "mask effect" which makes the acoustic tools attached to boats unreliable and often unable to highlight nesting defects and the real size of the holes.
These tools also flag non-conformities that do not exist, penalizing companies that rely on advice based on these technologies. Based on the tests we have conducted up to 2017, these tools can only be used once the shell has been recognized as TECHNOLOGY COMPLIANT to make a survey that will be attached to the as-built file as part of the future follow-up of the work. As part of this future monitoring, the comparison of old and recent images may highlight significant degradation. Otherwise, shells using TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ and X-bloc ® technologies must be classified as CLASS B CARAPACE.
The armour is potentially fragile and should be subject to annual monitoring and preventive maintenance.
CLASS B shells do not receive the quality mark 
because all our work has shown that with the presence of a CLAS inspector on the project, production is doubled and the work complies with CLASS A.
CLASS C
These are structures built with ACCROPODE ™, ACCROPODE ™ II, CORELOC ™, ECOPODE ™, XBLOC ® or other blocks whose durability cannot be guaranteed due to major non-conformities. Class C structures will see their functionality called into question at a deadline that depends on these major non-conformities and the occurrence of storms.
In this image, the as-built documents drawn up by the company showed perfect installation.
In reality the blocks were placed in second layer directly on a first layer of ACCROPODE™II
damaged by a storm whose ACCROPODE ™ II blocks are mixed with the riprap of the underlayer.
Block completely out of profile not detected by the installation and inspection tools on DAS ISLAND.
This installation was approved on the basis of an ECHOSCOPE survey which did not identify the off-profiles.
We supervised as third party the repair of 5000 meters of X-bloc ® armour.
Structures that are known to be poorly constructed and will suffer damage.
Blocks placed on very fine materials. Non-respect of design and non-respect of technology.
TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ and X-bloc ® class B shells can become class C shells due to lack of supervision and maintenance.
But it is rather the lack of care during construction, the non-respect of the design and the TID which lead to the classification of a shell in CLASS C.
Work built in total ignorance of the most basic construction rules. This armour is totally unstable
TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™, X-bloc ® or other CLASS C shells must be rebuilt.

ESSENTIAL INFORMATION
Following the company's accession to the BREAKWATER SOLUTION™ brand, it will not be possible to build a class B or class C armour. The use of a class A breakwater will be accepted, whichever block is used, TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™, X-bloc ®, BS1, BS2 or BS3.
