Аспирант и соискатель, № 1, 2017 ТЕХНИЧЕСКИЕ НАУКИ Строительство и архитектура Строительные конструкции, здания и сооружения Баженов А. <...> Добившись первого разрушения экспериментального сварного соединения, это соединение восстанавливали, после чего его вновь подвергали воздействию экспериментальной нагрузки и доводили до следующего разрушения. <...> EXPERIMENTAL AND CALCULATED ASSESSMENT OF THE FATIGUE LIFE OF REPAIRED WELDED JOINTS BASIC BLOCKS OF FIXED OFFSHORE PLATFORMS At present the problem of resource assessment of welded joints after there are repaired has important practical significance. <...> Of particular importance to such issues in the calculation of fatigue durability of welded joints of offshore platforms. <...> To evaluate the resource of repaired welded joints in the supported block of offshore platform is impossible today. <...> As it was established as a result of experiments performed by Bazhenov A. G., the chart fatigue fracture differs significantly according to diagrams. <...> Having achieved the first experimental destruction of the welded joint, the joint was restored, after which it was again subjected to experimental load and brought to the next fracture. <...> Basis of the research the fatigue chart for restored welded joints of basic blocks of fixed offshore platforms was built. <...> Keywords: fatigue cracks, fixed offshore platforms, variable stress, refurbished, remanufactured welded joints, fatigue curve. <...> The Russian Federation hosts vast existing and potential offshore oil and gas resources in the Black Sea, where oil is extracted with the use of offshore stationary platforms. <...> In some cases the total durability of these 39 Аспирант и соискатель, № 1, 2017 platforms can be more than 30 years [1; 3-9]. <...> As offshore stationary platform are used in unfavorable conditions with high corrosive activity, heavy loads and etc. corrosion – mechanical wear occur to them and it can be unsafe to use the. <...> The accident rate analysis of offshore stationary platforms for the past 30 years has shown that, though there are different hi -tech solutions to provide safety at offshore stationary platforms, the accident rate is still high. <...> Continuous operation of OSP leads to the necessity to introduce the fatigue criteria. <...> The literature r ecourse <...>
