摘要

Todyo Gas' third LNG receiving terminal, the Ohgishima terminal, goes into operation beginning october 1998 in the city of Yokohama. It is located adjacent to areas where city gas is in great demand. In the planning, designing, and construction of the LNG terminal, state-of-the-art technology has been fully incorporated and special attention has been paid to improved safety and protection of the environment, including the appearance of the surrounding landscape. In particular, the LNG Receiving Facilities and Storage Facilities were designed utilizing a brand new type of system. Features include an offshore berth for LNG tankers without bridges for pipelines between the berth and shore, a 2-km shield tunnel connecting the sea berth and the terminal, pipelines including 40B large-diameter LNG receiving piping accommodated in the tunnel, and a 200,000-kl large-capacity LNG underground storage tank constructed fully below ground level, including the concrete domed roof.
