Floating Emergency Bases

2.20 Floating Emergency Bases

As floating structures are inherently base isolated from earthquakes, they are ideal for applications as floating emergency rescue bases in earthquake prone countries. Japan has a number of such floating rescue bases parked in the Tokyo Bay, Ise Bay and Osaka Bay. Table 1 shows their specifications and Figs. 42 and 43 show the emergency rescue bases at Tokyo bay and Osaka bay, respectively (Watanabi, 2004).
