    • Provided is steam turbine equipment that enables the turbine equipment to be increased in size while inhibiting the possibility of vibration generation and a significant increase in equipment cost even when the steam temperature adopted is 650°C or higher. In a steam turbine equipment having a high-pressure turbine, an intermediate-pressure turbine, and a low-pressure turbine, the high-pressure turbine is separated into a first high-pressure turbine unit on the high-temperature, high-pressure side and a second high-pressure turbine unit on the low-temperature, low-pressure side; the intermediate-pressure turbine is separated into a first intermediate-pressure turbine unit on the high-temperature, high-pressure side and a second intermediate-pressure turbine unit on the low-temperature, low-pressure side; the first high-pressure turbine unit and the first intermediate-pressure turbine unit are integrated to configure a first integrated unit; the second high-pressure turbine unit and the second intermediate-pressure turbine unit are integrated to configure a second integrated unit; and at least one of the rotors or the casing of the turbine, into which steam at 650°C or above is introduced, is configured by joining multiple members formed of an Ni-based alloy by welding.
