THROUGH BORE SUBSEA CHRISTMAS TREES
Proceedings of Offshore Europe, 1985Abstract 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.

The Application of ROV for the Subsea Christmas Tree Installation in the LiWan3-1 Deepwater Oilfield
Applied Mechanics and Materials, 2013Chinas offshore oil and gas has been developed from shallow water to deep water. Subsea production facilities play more and more role in deepwater oil and gas fields, in which Christmas tree is the key equipment to control and regulate the oil well production of deepwater production systems, but it has great installation costs and risk.

ProcessesTo address the failure risks associated with long-term service of subsea Christmas tree-wellhead systems under the complex marine environment of the South China Sea, a multi-factor coupled mechanical analysis method is proposed to evaluate the system’s mechanical characteristics and ensure the safety of deepwater oil and gas production. A dynamic model

Abstract The fault propagation of multistate systems (MSSs) with various operational modes is a critical factor affecting the reliability and safety of systems. However, traditional methods have difficulty describing the influence of function transitions and multiple faults of components on fault propagation, and are inapplicable for accurately ...

Based on diverse situations of the flowline of subsea Christmas tree installation and its working conditions, a theoretical model for calculation of the flowline is proposed by taking comprehensive considerations of different influencing factors, such as water depth, temperature of petroleum and gasoline, and angles of the flowline. By using the ABAQUS

Buckling of Flowlines of Subsea Christmas Tree Based on Genetic Algorithm
ICPTT 2011, 2011By 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
