Long pipeline seismic design

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I found information in Internet regarding with the fuel pipelines seismic design. The sources refers to the use of the 'Multiple Support Excitation Analysis (MSEA)' for long pipelines, an approach developed for the Trans-Alaska fuel pipeline. There are any federal regulations that states the MSEA as a mandatory method for seismic analysis? Which is the boundary between the use or not of the MSEA? What about for non fuel-transmission pipelines, like long water lines? What about buried pipelines?
