The invention relates to a method for starting a steam turbine installation (1b) which comprises at least one steam turbine (20a, 20b, 20c) and at least one steam-generating installation (30b, 30, 44, 46, 52, 50) for generating the steam for driving the steam turbines (20a, 20b, 20c), the steam turbine installation (1b) having at least one casing component, which has an initial starting temperature of more than 250 ~C, the temperature of the steam and of the casing component being continually measured, and the casing component of the steam turbine installation (1b) being supplied with steam from the starting point onwards. The starting temperature of the steam is lower than the temperature of the casing component and the temperature of the steam is increased with a start transient and the starting temperature is chosen such that the change in temperature per unit of time of the casing component lies below a predefined limit. The temperature of the casing component initially decreases, until a minimum is reached and then increases.
