Strojniški vestnik - Journal of Mechanical Engineering, 2022 The subsea all-electric Christmas tree is key equipment in subsea production systems. If a failure occurs, the marine environment will be seriously polluted. Therefore, strict reliability analysis and measures to improve reliability must be performed before such equipment is launched, which is crucial to safe subsea production.

Free Convection Model Development for the Thermal Analysis of Cavities in Subsea Christmas Trees [PDF]
, 2014 A free convective heat transfer model was developed in ANSYS CFX for trapped fluid volumes located inside subsea christmas trees. Analytical and numerical solutions to the heat transfer problem were generated for a vertical concentric cylinder enclosure containing water in the annulus, with aspect ratios D_o/D_i = 3/2 and H = 10 D_o.

Quasistatic Nonlinear Analysis of a Drill Pipe in Subsea Xmas Tree Installation
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 To analyse the stress and deformation of a drill pipe during the lowering of a subsea Xmas tree, a mechanical analytical model and equation were established based on Euler‐Bernoulli beam theory. The wave phase is selected as one of the variable parameters for analysis of the deformation and stress of the drill pipe.
