(2)Directive 2009/15/EC forms together with Regulation (EC) No 391/2009 of the European Parliament and the Councilnote one coherent piece of legislation where the activities of recognised organisations are regulated in a consistent manner in accordance with the same principles and definitions. Pursuant to Article 3(2) of Directive 2009/15/EC, if a Member State decides, with respect to ships flying its flag, to authorise an organisation to carry out on its behalf the inspections and surveys related to statutory certificates, it shall entrust these duties only to a recognised organisation, which, pursuant to Article 2(g) of that Directive, means an organisation recognised in accordance with Regulation (EC) No 391/2009. Therefore, the set of rules on the basis of which the organisations concerned are recognised has an impact on both acts.
