As a submersible permanent magnet synchronous motor (SPMSM) must function in downhole high temperature crude oil for long periods of time, the accurate prediction its rise is crucial to improve stability motor. However, analysis field involves multiple physical fields, such as electric field, magnetic fluid and so on, it difficult calculate accurately. Motor loss usually loaded fixed value when calculating while reality, always changes with temperature. Therefore, calculation inaccurate...
To analyse the stress and deformation of a drill pipe during lowering subsea Xmas tree, mechanical analytical model equation were established based on Euler‐Bernoulli beam theory. The wave phase is selected as one variable parameters for analysis pipe. research results indicate that maximum response occurs at 0 radians in scope to 2 π , quasistatic nonlinear analysed 0. In addition, Orcaflex software applied simulation, simulation are compared with from proposed method, which demonstrate...
In this study, experimental and numerical investigations on the vibration characteristics of a drill pipe during lowering subsea Xmas tree were presented. A fourth-order partial differential equation with variable coefficients was established based Euler–Bernoulli beam theory. The natural frequencies mode shapes are obtained by using transformation method. Four models different sizes used in experiments which measured piezoelectric acceleration sensors fiber Bragg grating sensors,...
Abstract The purpose of this paper is to determine the safe operating window subsea tree installation through analysing sensitivity multiple environmental parameters. In paper, wave height, period, phase angle and sea surface current speed are taken as evaluation factors marine environment, a ranking these four obtained by orthogonal analysis. lateral offset axial velocity tree, deformation von-Mises equivalents stress pipe constrain in Results show that height period most significant...
