SYNTHESIS OF TECHNICAL/ECONOMIC STUDY CONCERNING THE INSTALLATION OF PLANTS FOR THE RECEPTION AND TREATMENT OF BALLAST NEAR LOADING TERMINALS IN THE MEDITERRANEAN
The more or less heavy, waxy and asphaltenic residues which in the past were generally unloaded in the sea with elementary washing methods consist of products which may be submitted to further treatment in the refinery: this type of recovery allows reaching two goals i.e. an economic practicability and the reduction of sea pollution. The operation which has been largely applied in a number of oil and transportation companies follows the "Load-on-top" system that was adopted by 75% of the world tanker fleet has without any doubt contributed toward restraining the magnitude of sea pollution which a disorderly unloading would have brought about. However, a number of significant limitations, which are covered in the report, still limit its use: (a) the result is really efficient only if all operations are carried out with perfect timing: (b) the minimum period of time required to carry out operations excludes the fact that the method can be applied efficiently with ballast in relatively short trips such as the usual Mediterranean voyages. A technical solution foresees the achievement of equipment suitable for the reception and treatment of tanker ballast and washing waters, near all loading terminals. This solution may be carried out by installing near each crude oil port loading, the following equipment: 1) mooring-treatment plant connection to unload ballast waters; 2) storage of ballast waters; 3) continuous de-oiling plant for these waters; 4) sea unloading manifold of waters treated. A total investment evaluation is also provided for each of nine Mediterranean ports.
