ESTIMATION OF THE SURVIVABILITY INDEX OF FLOATING DRILLING RIGS DURING THEIR OPERATION ON THE ARCTIC SHELF

Key words: <\/strong>: arctic, exploration of offshore hydrocarbon resources, floating drilling rig, deterministic approach, probabilistic analysis, rig survivability, survivability index, event tree, protective barrier, semi-submersible floating rigs, ice resistance, ice conditions, ice conditions, ice control subsystem, physical physics, ice management subsystem, ice management systems, level of safe operation of the installation.<\/p>\n

The issue of ensuring the integrated safety of floating drilling rigs (FDR) in the process of developing the Arctic shelf of the Russian Federation is extremely relevant. When designing a control system, possible loads and effects are taken into account using a deterministic approach, while most factors affecting them are probabilistic in nature, and the values of these factors can periodically exceed the accepted design values. A probabilistic approach is proposed in the work, which assumes the calculation of the FDR survivability index from an event tree under the influence of one or another initiating factor. The methodology of the approach is described, the results of calculations are analyzed on the example of the operation of FDR in ice conditions. Such an approach allows one to take into account the multivariance of scenarios of the influence of external factors on the state of the control system, as well as various components of security barriers.<\/p>\n
