Earthquakes can cause terminal damage to mechanical structures starting with piping systems, as seen in recent years in the Great Hanshin Earthquake. NHK Spring provides seismic analysis services and support design services as countermeasures to verify and assure soundness of those structures.

In the Great Hanshin Earthquake, not only buildings and civil engineering works, but as seen in photographs, construction equipment and factory facilities also suffered great damage. The danger of a Tokai earthquake or Tonankai or Nankai earthquake is said to be imminent.　

Aren't countermeasures needed now?

Based on experience acquired in piping support design such as for nuclear power plants, NHK Spring provides assistance with seismic countermeasures for plant facilities, building equipment and various types of equipment.
