Certain tasks currently done at Community or national level could be executed by a specialised expert body. Indeed, there is a need for technical and scientific support and a high level of stable expertise to properly apply the Community legislation in the fields of maritime safety and ship pollution prevention, to monitor its implementation and to evaluate the effectiveness of the measures in place. There is a need therefore, within the Community's existing institutional structure and balance of powers, to establish a European Maritime Safety Agency ("the Agency").
