Abstract
Methods for determining the bearing capacity of the supporting bases of offshore platforms under geodynamic influences in conditions of increased oil and gas production
Incoming article date: 15.02.2024This article discusses the main factors leading to a decrease in the bearing capacity of the support bases and the possible loss of stability of the offshore platform, which will entail emergency consequences. The impact of free gas in the upper sections of the soil and dynamic external loads on the safety of construction and operation of oil platforms has been assessed. Calculations for the bearing capacity of the pile foundation of the support bases of the SPBU Astra in the Caspian Sea, performed according to existing methods, were analyzed. The determination of the strength of the soil is carried out for the calculated support surface – the section of the column having the maximum area.
