Old Port of Bastia and seafront road - CORSICA : an ACCROPODE™ II and ECOPODE™ project

Old Port of Bastia and seafront road - CORSICA

The Collectivity of Corsica has appointed the NATALI & BUESA S.A.S consortium to rehabilitate the two breakwater of the Old Port of Bastia: The Dragon’s jetty and the Genoa Mole, including the installation of 2,000 ACCROPODE™ II blocks of 6m3 and 9 m3.

After several storms, the two breakwaters of the Old Port of Bastia had weaknesses in their armour. The works were carried out by sea, starting with the 150-metre Dragon’s Jetty, after an initial phase of extraction and removal of TETRAPODE blocks. The Old Port of Bastia is also an innovative project with the placement of 20 ECOPODE™ blocks underwater in order to study how fast the biodiversity develops on these macro-textured artificial blocks.

The added value of CLI

Provision of required technical elements for the good completion of the armour layer in accordance with the Contractor’s needs.

Special features of the project

  • Interaction with breakwaters works in a still active port
  • Deconstruction of the existing structure with the extraction of TETRAPODE blocks
  • The use of ECOPODE™ blocks and the associated environmental monitoring
  • The complexity of the implementation of the rock-breaking for the realisation of the feet berm

Hydraulic conditions

  • Dragon's Jetty: 150 m
  • Genoa Mole:  115 m
  • Max. seabed depth (toe): -18 m MSL
  • Top of the crest: +3.23 m MSL
