The hire cost is different for each vessel and it is "pre-agreed" during the tender phase of each project. The price that the Member State (or other contracting party) would have to pay in case of emergency is considerably lower than the cost of hiring a vessel in the open market. This pre-agreement facilitates a quick response, obviating the need for difficult and time consuming negotiations. The hire cost of each vessel is confidential information that is only distributed to the relevant authorities within the Member States.
