Abstract

В изобретении предлагаются способ и система оценки наихудшего случая коррозии в трубопроводе, для которого измерения толщины стенки трубопровода ограничены выборочными ультразвуковыми или рентгенографическими (UT/RT) измерениями. Библиотека данных содержит распределения измерений внутреннего контроля (ILI) для других трубопроводов, калиброванные должным образом в соответствии с UT/RT измерениями. Эти ILI наборы данных выбирают случайным образом множество раз, чтобы получить множество наборов образцов для каждого ILI набора данных. Производят оценку возможных статистических распределений для каждого набора образцов, чтобы определить, какое из возможных статистических распределений наиболее точно оценивает наихудший случай коррозии, измеренный при помощи ILI. Затем выводят классифицирующую функцию из статистики и выводят трубопроводные дескрипторы, связанные с наборами образцов, вместе с наилучшим возможным статистическим распределением для этого набора образцов. Статистику и трубопроводные дескрипторы для трубопровода с выборочными UT/RT измерениями затем применяют к классифицирующей функции, чтобы определить наилучшее одно из возможных статистических распределений для оценки экстремального значения и наихудший случай коррозии затем определяют с использованием этого наилучшего статистического распределения.
