Ujina Floating Ferry Pier and Kan-On Floating Breakwater, Japan
This chapter describes the construction of the Ujina Floating Ferry Pier and Kan-on floating breakwater. This Ferry Pier was set up at Hiroshima Bay in Japan in 1993. At 150 m in length, 30 m in width, and 4 m in height, it is the largest in Japan. Five prestressed concrete pontoons (30 m in length, 30 m in width, and 4 m in height) were fabricated on land and towed to the pier site for assembly to form the floating pier with a total length of 150 m. The Kan-on Floating Breakwater was set up at Hiroshima Bay in 1994. The breakwater is one of the world's largest classes of floating breakwaters made from reinforced concrete and steel plates. Three units of the breakwaters measure 97.8 m in length, 20.0 m in width, and 2.5 m in height while another two units are 70.75 m long, 21.0 m wide, and 2.5 m high.

A part of the document of the Project of Ujina Floating Ferry Pier was provided by the Hiroshima Port and Airport Office, Ministry of Land, Infrastructure, Transport and Tourism, and a part of the document regarding the Project of the Kan-on Floating Breakwater was provided by the Hiroshima Port and Harbor Promotion Office, Hiroshima Prefectural Government. The authors wish to express their sincere appreciation to Mr. Hideyuki Hokimoto (from Chuden Engineering Consultants Co., Ltd.) who provided much advice on both projects.
