Abstract
A method for operating a cooling system of a ship, having a sea water part system with a sea water pump (14a, 14b) and at least one first cooling water circuit. The first cooling water circuit includes a bypass in a heat exchanger coupling the sea water part system and the first cooling water circuit and a control valve. A position of the control valve determines a cooling water proportion of the first cooling water circuit that is conducted via the heat exchanger and a cooling water proportion of the first cooling water circuit that is conducted via the bypass. The position of the control valve is controlled such that an advance cooling water temperature corresponds to a set point value. The rotational speed of the sea water pump is controlled based on the position of the control valve.
