OVERVIEW

The power market has seen rapid deregulation and liberalization, and this has strongly motivated the power industry to streamline equipment costs and reduce construction schedules. This calls for a radically new construction method that can respond and accurately target these needs. The conventional approach has been to construct heavy equipment such as condensers in fabrication shops and deliver the finished equipment to the site, which involves a number of restrictions. To overcome these restrictions, Hitachi built the Futo Factory at the 4th wharf of Hitachi Port in September 2000 specifically to fabricate condensers. A permanent crane capable of lifting up to 500 t is situated near Futo Factory and is capable of shipping condensers implemented as large blocks. Using this facility, the time frame needed to fabricate and install equipment for the Hokuriku Electric Power Company's Shika Nuclear Power Station Unit 2 (SU2) has been substantially reduced.
