Summary

 
The paper is analysing the seismic activity maps and demonstrates that it is required to take into account the seismic effects in the design of ground-supported offshore structures to be operated in the Black Sea, Sea of Azov, Caspian Sea and Sea of Okhotsk. The seismic effects is that for estimating the seismic resistance of jack-ups it is required to determine the seismic resistance of the rig’s parts grouped by functions. The seismic resistance for each group shall be estimated for two levels of impacts: design earthquake and maximum design earthquake using the theory providing the most adequate results.
