Construction of submarine pipelines plays an important role in offshore development. Japan is famous for earthquake country. It is very important to estimate the earthquake proof of the submarine pipelines. An oil leakage causes the contamination of ocean if the submarine pipelines are damaged by earthquakes. Pipe stresses during earthquakes are closely related to the relative displacement of the ground. Field observation has been carried out to know the ground deformation. Steel pipe is assumed to be buried along the observation line and pipe stresses are calculated from the ground deformation obtained by the field observation. The stresses calculated by seismic deformation method that has been used for earthquake resistant design in Japan and by dynamic response analysis are compared with those from the observation.
