Губкина МЕТОДИКА ИЗМЕРЕНИЯ ВЛИЯНИЯ СОЛНЕЧНОГО СВЕТА НА МОРСКИЕ НЕФТЕГАЗОВЫЕ СООРУЖЕНИЯ СТАЦИОНАРНОГО ТИПА Морские нефтегазовые сооружения, в частности платформы стационарного типа становятся объектом солнечного излучения, что может негативно повлиять на долговечность этих конструкций. <...> METHODOLOGY OF EVALUATING THE SOLAR RADIATION IMPACT ON THE TEMPERATURE CONDITION OF FIXED OFFSHORE PLATFORMS Some structural elements of offshore fixed platforms are intensively exposed to the solar radiation. <...> Hence, these elements undergo a variety of changes connected with temperature conditions. <...> This paper briefly describes the most important changes, such as thermal stresses, negative deformations, possible fatigue cracks and suggests a method to estimate rig exposure to light. <...> Offshore oil and gas facilities are exposed to a variety of factors affecting their temperature state. <...> The main factors influencing the temperature formation of the structural elements of the offshore oil and gas installations are solar radiation and the environment. <...> For accurate assessment of the temperature state of the substructure elements (steel jacket) it is necessary to take into account such factors as the degree of transparency of the atmosphere, wind exposure, heat dissipation into the environment and other factors, which will be discussed later [1; 5-13]. <...> The substructure elements located in vulnerable areas of sun exposure are subject to significant heat effects. <...> Measurements conducted on platforms located in the Black sea have shown that under certain conditions, the temperature of the horizontal elements can reach up to plus 80 degrees Celsius [1; 5-13]. <...> As it is known, the change of temperature in the cross sections of offshore fixed platforms elements creates alternating voltages, which in turn adversely affects fatigue life, and under certain conditions contribute to the development of various defects, including fatigue cracks. <...> Unlike oil and gas pipelines, in which the temperature state is primarily determined by the temperature of the pumped product, temperature schedule of fixed offshore platforms substructures is determined by various environmental conditions, key among which is the intensity of solar radiation. <...> It is commonly known that the Sun is from the Earth at a distance of about 150 mln km. [3; 4]. <...> Since the longitudinal axis of the Earth moves around the Sun in an elliptical orbit <...>
