The concept of seismic isolation is not new, but it has not generally been used in heavy industrial settings.
The European project, INDEPTH (Development of INnovative DEvices for Seismic Protection of
PeTrocHemical Facilities), supported by the Environment and Sustainable Development Programme of
the European Commission Research Directorate General (Contract EVG1-CT-2002-00065), has, as its
objective, the development of new base isolation devices, suitable for application at refineries, LNG and
petrochemical facilities beneath critical structures, such as cylindrical tanks and spheres. The intent of isolation to reduce seismic risk and enhance performance reliability, especially for beyondvdesign basis events, since many of these critical facilities are located in areas of high seismicity worldwide.
In conjunction with development of isolation devices, new flexible piping joints will also be developed in order to accommodate increased displacements beneath isolated structures.
