Journal ArticleDOI

Reliability prediction of an offshore wind turbine gearbox

TL;DR: In this article, the failure rate of an offshore wind turbine gearbox based on the data available for similar, known onshore wind turbine systems is estimated and a reliability prediction method is illustrated stepwise to estimate the total failure rate.
Journal ArticleDOI

Reliability assessment of thick high strength pipelines with corrosion defects

TL;DR: In this article, the reliability of high-strength pipelines subjected to internal pressure by first-order reliability algorithms and Monte Carlo simulation methods is assessed and the uncertainty associated with model uncertainty factors is addressed and the best fitting distribution is identified.
Journal ArticleDOI

Reliability assessment of a subsea pipe-in-pipe system for major failure modes

TL;DR: The structural reliability of a pipe-in-pipe system operating in deep-waters under high internal pressure and high temperature is assessed and the effect of limit state variables on the probability of the PiP failure modes is assessed.
Journal ArticleDOI

Uncertainty in reliability of thick high strength pipelines with corrosion defects subjected to internal pressure

TL;DR: In this article, the uncertainties in the structural reliability levels of pipelines with active corrosion defects subjected to internal pressure were assessed by Monte Carlo simulation and a 3-parameter lognormal probability model was adopted to describe the uncertainty in the burst pressure.
Journal ArticleDOI

Uncertainty quantification of burst pressure models of corroded pipelines

TL;DR: In this article, a comprehensive review, calibration and model uncertainty evaluation of a wide range of burst strength models available in the literature relative to a large sample of more than 240 tests of burst pressure covering a variety of steel grades is provided.
