A case study of middle size floating airports for shallower and deeper waters
- Univ. of Tokyo (Japan). Dept. of Naval Architecture and Ocean Engineering
Demands for large and middle size airports are expanding in Japan with continuous increase of air transportation. However these demands will not be satisfied without effective ocean space utilization. Most of the wide and shallower waters suitable for reclamation have already been reclaimed. Furthermore those shallower waters are generally close to the residential area, and noise and environmental problems will be caused if they were used for airports. Deeper waters, which are relatively distant from the shore, are suitable for airport but reclamation of these waters are extremely difficult. This paper presents a structural planning of an open sea type middle size floating airport to promote local economy and also improve transportation infrastructure of isolated islands. The airports of this plan are a semisubmersible type floating structure with a relatively thin deck, a number of slender columns and large size lower hulls. The floating structure is moored by inclined tension legs to restrain the motion. The diameter of the leg becomes much larger compared with the legs of existing tension leg platforms. Parameters related to the configuration of the floating structure and the mooring system are determined by comparing analyses results with the proper design criteria. Several kinds of static and dynamic computer programs are used in the planning. The proposed structural plan and the mooring system are considered as a typical floating airport appropriate for the open sea.
