Environmental protection and workplace safety are two of the top priorities of the Concordia reclamation project.

Monitoring activities

At the Prà Voltri worksite the quality of the water is being monitored with samples collected on a daily basis on the surface; in addition, once a fortnight underwater sampling is conducted together with monitoring of sediment.

The quality of the air is also measured by means of four monitoring stations and a central control room where the data are compared with the situation prior to the arrival of the ship.

As regards noise, measurements will be recorded using sound level meters placed in worksites in the shipyard and in the nearby residential area.

The activities are coordinated by a team of environmental engineers and laboratory technicians. To date, no critical data have been recorded.

Oil booms

Before the start of operations, booms and other absorbent sponges and skirts were put in place around the ship at the “Porto di Prà Voltri” Seawall. This was done in order to contain any spill of oil or other floating substances.

Underwater assistance service

Divers will be working both at the Prà Voltri site and at the “Molo Ex Superbacino” dock. Also, underwater inspections of the hull will be conducted with the assistance of ROVs (Remote Operated Vehicles).

Oil Spill Rapid Response Unit

Multi-disciplinary rapid response units specialising in fire prevention and environmental response activities are available 24/7 should the need arise (e.g. for removal of any spill).

Gas emission reduction systems

During emptying and cleaning of the cold storage rooms and food storerooms, local systems of abatement of any effluent gas will be adopted using activated carbon filters. The microporous structure of the filters is designed to remove VOCs (volatile organic compounds), pollutant molecules and odors.


Should the need arise, air freshening systems will be used; these nebulization systems convert liquid fragrances into a vapor that is effective over an area extending dozens of meters.

Magnetic sheeting

During towage from the “Molo Ex Superbacino” dock to Dry Dock no. 4, magnetic sheeting will be placed over the openings in the damaged parts of the submerged section of the hull in order to minimize the possibility of accidental discharge of materials.

Industrial water treatment system connected to the dry docks

The Port of Genoa has an industrial water treatment system directly connected to Dry Docks no. 4 and 5 (Authorization no. 5341/10 – issued by the Genoa Provincial Administration). This system, which will be used during Phase 4 of the dismantling, consists of two lines with combined capacity of approximately 350 m3/hour.



  • Surface (daily sampling).
  • Underwater (sampling once a fortnight – 89 parameters).


  • Measurements recorded during yard operations and compared with data collected before dismantling started.


  • Sediment sampling once a fortnight.


  • 4 air quality monitoring stations and a central control room.
