Abstract
Supports are provided on the upper outer casing of each turbine of a turbine unit, and the upper inner casing of the turbine is temporarily placed on the supports of the upper outer casing, which is temporarily placed on the operating floor. By placing the casings temporarily in that way, a large space can be secured for the inspection of the turbine unit, and the inspection can be carried out quickly, which increases the operation ratio of the whole plant including the turbine unit. This invention is useful mainly for turbine units and their overhaul.
