The Safety Estimation of the Marine Pipeline

Abstract

Reliability assurance and safety assurance are the definitive requirements for marine pipelines whose damages give rise to environmental disasters, while damages repair is very complicated. In view of high operation loads, the pressure and temperature effects combined with the account probable natural extreme effects these requirements make it necessary to tackle many problems associated with evaluation of «pipeline-soil» system interaction. The analysis of these interaction mechanisms has been carried out on the basis of foreign (DNV) and domestic standards.This article focuses on the problem of imposing special (seismic) loads and on engineering methods of measuring medium resistance forces; the subject matter of the article also includes the issues of the marine pipeline safety (risk) evaluation, using the theory of runs as applied to random seismic effects. The requirements for sealines in Russia are governed by Sealine Regulations.
