Trend of utilization of ocean space according to structural form of oceanic architectures

The aims of this research are to understand the construction history, subsequent refurbishment, and use of existing oceanic architectures and to clarify the establishment cause, location, and facility use of oceanic architectures, from which the current state of the oceanic buildings and propose new ways of using maritime areas in the future may be recognized. First, a wide variety of facilities of oceanic architectures have been built all over Japan in line with economic growth since 1960. However, in the 2000s as public interest in oceanic architectures become sluggish, many facilities have been forced to close. After these circumstances, the use of marine areas has been recognized again in recent years, and the interest in oceanic architectures has been reintroduced. For the survey method, existing examples using aerial photographs are confirmed and the operation status of the facilities are clarified. Based on this, we selected ten study subjects. We carried out on-site survey at the target facilities and conducted interview survey to local governments, facility owners, and other concerned parties. In addition, relevant design books and materials are collected, and facility outline, construction history, usage trends, and the surrounding locations are studied. As a result, it was confirmed that oceanic architectures are closely related to the surrounding seas. In addition, it was confirmed that oceanic architectures have a certain base as regional entities, and increasing the usefulness of facilities can be achieved by acquiring new added values through continuous use of the maritime area.
