At the port that was hit by the great tsunami caused by the Great East Japan Earthquake 10 years ago, the port was severely damaged by a ship hitting it and the facilities were destroyed, so the Ministry of Land, Infrastructure, Transport and Tourism has put together new measures to reduce the damage to the port. It was.
In the Great East Japan Earthquake, a large tsunami struck the ports of Tohoku and Kanto, and more than 50% of the ships moored in the survey by the Ministry of Land, Infrastructure, Transport and Tourism were unable to evacuate in time and collided with the quay, damaging the facilities and landing on land. There was a great deal of damage.
After the earthquake, the Ministry of Land, Infrastructure, Transport and Tourism is proceeding with the development of quays that are resistant to the shaking of the earthquake, but we have newly summarized measures to reduce secondary damage to the port by ships.
According to this, it is effective to moor the ship from the outside of the port instead of pointing the front part of the ship to the inside of the port so that the ship can evacuate to the outside of the port immediately after the tsunami warning is issued. It is said.
At some wharfs in Nagoya Port, efforts have already begun to moor the front part of the ship toward the outside of the port.
In addition, assuming that the ship will hit, it is said that equipment to cushion the impact on the quay and seawall and fences to prevent the ship from riding on the quay should be installed.
The Ministry of Land, Infrastructure, Transport and Tourism has decided to focus on software measures such as revision of the port BCP = business continuity plan, saying that it takes time and cost to take measures on the equipment side.
