Dynamic Bayesian network-based reliability and safety assessment of the subsea Christmas tree

Process Safety and Environmental Protection, 2021
Abstract The major functions of the subsea Christmas tree include production management, wellhead pressure control, chemical reagent injection, and oil/gas production safety control. It is necessary to investigate the reliability and safety of the tree for safe and stable operation of subsea production systems.

Reliability Analysis Method of a Control System for Subsea All-Electric Christmas Tree

Journal of Marine Science and Application, 2021
The subsea all-electric Christmas tree (XT) is a key equipment in subsea production systems. Once it fails, the marine environment will be seriously polluted. Therefore, strict reliability analysis and measures to improve reliability must be performed before a subsea all-electric XT is launched; such measures are crucial to subsea safe production.

A New Technique to Solve Gas Hydrate Problems in Subsea Christmas Trees

SPE Production & Facilities, 2004
Summary The paper is aimed at describing the series of actions taken to re-enter a well, the (wet) Christmas-tree cap of which was clogged by solid hydrate and therefore could not be released by means of a regular releasing tool.

A dynamic Bayesian network based methodology for fault diagnosis of subsea Christmas tree

Applied Ocean Research, 2020
Abstract A subsea Christmas tree (XT) is an extremely important part of a subsea production system. The safety-fault of subsea XT indicates that no major safety incidents are difficult to diagnose. To identify the faulty components and distinguishing the fault types, including the blocking, leakage, and especially safety-fault, we present a dynamic ...

Remaining useful life re-prediction methodology based on Wiener process: Subsea Christmas tree system as a case study

Computers & Industrial Engineering, 2021
Abstract With the continuous improvement of the complexity and comprehensive level of the system, its reliability becomes more and more important. The remaining useful life (RUL) estimation method using the degradation model with random effect to describe the degradation process of the system has been widely used such as Wiener process.

THROUGH BORE SUBSEA CHRISTMAS TREES

Proceedings of Offshore Europe, 1985
Abstract The workovers of subsea completed wells are expensive and time consuming as even the most routine tasks must be carried out by a semi-submersible. This paper describes the economic, safety and operational advantages which led to the development and successful first installation of ‘through bore’ subsea production trees.

Buckling of Flowlines of Subsea Christmas Tree Based on Genetic Algorithm

ICPTT 2011, 2011
By using the ABAQUS software, a finite element model for the flowline operating in South China Sea is developed and the structural strength analysis of the flowline under different water depth is performed. Meanwhile, by using genetic algorithm, the variation trend is forecasted, which is based on the calculation results of the flowline under different
