Russia has a large number of fixed offshore platforms, which were built during the Soviet era and are in operation for more than 20 years. In connection with such a long life platform for a long time was exposed to various loads that cause stresses and variables as a consequence of fatigue damage. In connection with this very urgent becomes the problem of estimation of residual resource of elements of the platforms with consideration of cumulative damage. Obviously, the residual resource it is long maintained elements of platforms subjected to intense impact, will differ from that caused by changes in the metal structure and the accumulation in it of fatigue damage. In this article the solution to the problem of determining the fatigue limit for the elements of the platforms with accumulated damage based on the experiments is proposed.
