PROBLEM TO BE SOLVED: To easily repair and exchange an electric power conversion module by providing many casings between upper and lower platforms, detachably arranging electric power conversion modules in the respective casings to previously assemble as a composite body, carrying it in a hull, and supporting it through vibrationproof mounts. SOLUTION: Two plane platforms 12 placed separately upper and lower and connected together with many upright pillars 14 are supported in a hull construction through a plurality of vibrationproof mounts designed so as to protect them from impact or vibration. In the casings 20 arranged between the upper and lower platforms 12, 12, one or more electric power conversion modules 20 are detachably provided. The respective casings 20 are formed by welded partition walls 22, and working force supply panel 24 to which electric cables 30 and cooling liquid pipings 32 supplying electric power and cooling liquid to the casings 20 are connected is provided. The platforms 12, pillars 14, the casings 20, and the using force supply panel 24 are previously assembled as a composite body, and it is supported with vibrationproof mounts. |
