The paper presents some paths to reduce EEDI as are applied onboard a 5550 TEU C/V and their effects upon ship’s performances.

In the transport domain, Romania holds a key position at the eastern border of the European Union, a transit area, both in the east-west direction (connection with Asia via the Black Sea), and north-south (from the Baltic Sea to the Mediterranean Sea). Three of the priority axes TEN-T cross the territory of Romania. We believe that using compressed air instead of fossil fuels will also determine a fuel economy of approximately 42% leading to the improvement of the companies finances which use these systems.

The extensive use of chemical substances in the technological processes demands special measures concerning the protection of the environment. A major problem is the purification of industrial waste water.

The principles of the two classes of risk assessment methods and the advantages and disadvantages of their application in environmental risk assessment are presented. For both methods, there is a wide range of techniques and tools with applicability more or less specific to certain types of risks. The risk matrix method with its many application forms and examples are presented. Also, it analysed the environmental risk associated thermal plants by risk matrix method.
