The study had been started from the review^<19)> of "Plan of Ocean Raft System for Hydrogen Economy"^<1)> which was proposed by Ohta^<1)> and Veziroglu in 1977. The project was for hydrogen production with solar energy on a huge raft floating on the South Pacific Ocean and for transport of liquefied hydrogen.Since their raft system was found to have some fatal defects in hydrodynamical and structural characteristics, an alternative plan of new raft system was proposed in which those defects are improved.In these papers (three reports will continue after this), authors carried out the feasibility study on the total plan only from technical view point. Economical view point was excluded here.In the first report, a new raft system is proposed as an alternative one. After natural condition such as wave, current and wind of the concerned area (8°S, 138°W) was surveyed, environmental force was estimated and the behavior of the raft was investigated both analytically and experimentally. Detail design of each structural members was conducted under consideration of the structural response for the load mentioned.The new raft system proved to be efficient for collecting solar energy and to be superior in hydrodynamical and structural characteristics.
