Abstract
The No. 2 coal loading berth for vessels up to 100000 D. W. T. at the Matsuura Power Plant of the Electric Power Development Company is 30 m wide and 350 m long. The berth is constructed of vertical steel piles with a reinforced concrete deck. In construction of the concrete deck, a steel stage was developed for forming and support of the concreting work. The stage is reusable. It can be dismantled and submerged and then moved to another construction block. Use of this stage contributes to reduction of the construction period and construction costs. This paper gives an outline of this submersible mobile stage and its method of use in constructing a concrete deck.
