震災時の東京港における内航貨物船からの陸上電力供給量の推定

抄録

  Japan is a country prone to many natural disasters. There has been a further demand for Japan to improve the reliability of power supply than before the Great East Japan Earthquake. Given the topography of the country, the authors think that the Earthquake taught us how effective ship-to-shore power supply systems are in improving the reliability. This study is to estimate how much power can be supplied from coastal cargo ships moored at Tokyo Port. For calculation purpose, the authors used ship specification data listed in the annual "Register of Ships" published by the Japan Shipping Exchange, Inc. and port mooring facility specification data on the Tokyo Port Facilities List. The result of the calculation showed that 230 moored ships at the port can provide up to 197,000kW, which accounts for 23% of the total amount of power that can be supplied from 2,314 registered coastal cargo ships in Japan.
