Description of the phases of the dismantling and recycling project
The Ship Recycling Consortium project for the dismantling and recycling of the wreck of the Concordia is being carried out in four separate operational phases, which are expected to last for a total of about 22 months. At different times during the various phases, the number of personnel deployed may range from 100 to 250.
The main objective of the project is to complete the job successfully and guarantee the least possible impact for the environment and the personnel deployed, through constant monitoring and the adoption of systems specifically designed to reduce the environmental impact.
The dismantling work will be arranged with the aim of maximizing the separation of the different types of discarded materials for recovery, enabling recycling of approximately 80% of this material. It is estimated that around 50,000 tonnes of steel and other metals will be obtained from the wreck of the Concordia.
This phase will see the involvement of experts in environmental protection, ship dismantlting, marine engineering, naval architecture and waste management.
After the wreck was towed to Genoa, the Ship Recycling Consortium drafted and presented to the relevant public authorities a Ship Recycling Plan describing in detail all the reclamation activities envisaged. The Ship Recycling Plan also includes a detailed Waste Management Plan illustrating the procedures for the management (disposal/recycling/reuse) of all the materials obtained.
PHASE 1: Arrival and stripping of the Concordia
This phase started with the mooring of the ship at the “Seawall” pier in the Port of Prà Voltri on July 27, 2014. After the technical handover by Titan Micoperi – the consortium that carried out the salvage operation on Isola del Giglio to right and remove the Concordia – the Ship Recycling team performed important operations related to yard safety and preparation for initial ship breaking and stripping of the interiors – specifically:
- Installation of the shipboard fire-fighting system
- Completion of the lighting system
- Installation of the necessary wiring and electrical installations
- Installation of elevators for transportation of materials
- Safety measures – e.g. repair of the gunwale/bulwarks, closure of certain shafts and spaces, protective measures in stairways, installation of gangways affording access to the ship
- Installation of one crane on the lido deck (about 60 meters in height) and another one forward for lifting materials
- Creation of openings required to remove materials and load them on barges for transportation to a dedicated area of the port
- Winterization of mooring arrangements (in case of adverse weather conditions during the winter season).
At the same time all the administrative procedures were carried out in order to obtain the permits and authorizations required, the last of which was duly issued on October 9, 2014.
Next, work began to strip and remove the furnishings and fittings of the decks above water. The objective of this phase is to obtain a reduced draft enabling the ship to be moved to the “Molo Ex Superbacino” dock.
The “Porto di Prà Voltri” location consists of two separate worksites: the “Seawall”, chosen for initial mooring of the wreck, and the pier at the far end of the “Banchina di Voltri” quay, where facilities have been set up for logistics operations and waste management.
At present, stripping operations are being performed on the uppermost decks at the bow and amidships and they will gradually be extended to the other areas working from the highest decks down.
It has been estimated that the reduction in draft required to allow transfer of the wreck to the “Molo Ex Superbacino” dock will be attained once around 8000 to10,000 tonnes of material has been removed. It is expected that this first phase should be completed by the first few months of 2015 and will involve the deployment of up to 200 people.
PHASE 2: Transfer to the “Molo Ex Superbacino” dock and dismantling of decks 14 to 2
The wreck will be transferred from the “Seawall” pier at Prà Voltri to the “Molo Ex Superbacino” dock, where the structures of decks 14 to 2 will be dismantled, including stripping of the interior furnishings and fittings on the decks when they emerge as the work progresses.
The deck structures will be removed in such a way as not to adversely affect the stability or longitudinal strength of the hull.
Preparation for transfer of the wreck to Dry Dock no. 4
The main operations in this phase will be the creation of buoyant force in the ship by making several compartments watertight and possibly installing airbags, thereby enabling the subsequent removal of the 30 sponsons, which will be done in accordance with specific procedures.
In addition, the food storerooms and cold storage rooms on deck 0 will be cleaned.
Following this, the wreck will be towed to Dry Dock no. 4.
PHASE 4: Final dismantling operations
This phase will involve the complete disassembly of the wreck, with the operations carried out in the segregated area of Dry Dock no. 4.
The work will also comprise the removal of the other interior fittings, clean-up of the various areas and final demolition of all the remaining structures.
This phase will conclude with appropriate handling, disposal and recycling of the discarded materials.
