Abstract
Today, oil, gas and other useful resources are being actively extracted at offshore fields using fixed offshore platforms. According to Federal Law No. 116 On Industrial Safety of Hazardous Production Facilities, offshore platforms are classified as hazardous production facilities, accidents at which are accompanied by significant damage. To prevent accidents at these facilities, an industrial safety examination is carried out, during which their resource is determined. The key parameter for determining the resource is the value of the endurance limit (or fatigue limit). Various theories are currently being applied to determine the fatigue limit. However, calculations on these theories give different results. The purpose of this article is to study various methods for determining endurance limits using welded joints of fixed offshore platforms as an example and choosing a method that allows you to obtain the most accurate value of this limit.
