To provide a method for controlling a condensate system and a condensate system, each of which enables condensate level inside a condenser to be appropriately maintained even when vacuum state inside the condenser changes, and to provide a ship with the condensate system.SOLUTION: There is provided the method for controlling a condensate system 1 comprising: a condenser 10 condensing steam exhausted from a steam turbine to obtain condensate; a gland condenser 12 heating the condensate from the condenser 10; a tank 14 storing a part of the condensate from the gland condenser 12; a condensate pump 16 provided between the condenser 10 and the condensate inflow side of the gland condenser 12; a condensation level control valve 18 provided between the condensate discharge side of the ground condenser 12 and the condenser 10; and a condenser internal pressure detection part capable of detecting the pressure inside the condenser 10. The method for controlling the condensate system includes: a rotational speed switching step of adjusting the minimum rotational speed of the condensate pump 16 in accordance with the pressure inside the condenser 10, which is obtained by the condenser internal pressure detection part.SELECTED DRAWING: Figure 1
