Providing safety and reliability in the design of the offshore ice-resistant stationary oil and gas structures
Safety and reliability factors, assumed in Russian and international standards, as well as the main provisions of design of offshore oil and gas structures are considered in the article. The reasons for structures destruction are classified. The analysis showed that the main design provisions and methodology of calculations related to provision of safe and reliable operation of offshore oil and gas structures by different standards are not fundamentally different: the required degree of reliability of the structure is set depending on the social and economic consequences of possible hydrodynamic accidents; calculations are based on the limit states design method using partial safety factors; etc. However, the factors accounting the degree of the structure reliability, partial safety coefficients and load combinations coefficients differ in different standards and methodologies.
