Abstract

Technical system (2; 2′), method and uses for dosing of at least one liquid treatment means (12) into injection water (16) to an injection well (22), wherein the technical system (2; 2′) comprises: —an underwater line (14; 14′) for transport of the injection water (16) from a shipment site (20; 48) for the injection water (16); and —at least one liquid-tight storage unit (10) containing the at least one liquid treatment means (12). The distinctive characteristic is that the at least one storage unit (10) is structured as a volumetrically flexible unit; —wherein said storage unit (10) is placed under water (6); and —wherein said storage unit (10) is connected, in a flow-communicating manner, to the underwater line (14; 14′) for dosing of liquid treatment means (12) into the injection water (16) to the injection well (22).
