Synchronous Test Platform for Functionality Verification and Structural Capacity Evaluation of Subsea Equipment

摘要

In order to verify the functionality and evaluate the structural capacity for subsea equipment simultaneously, a synchronous test platform was established, which consists of the test setup part and the data measurements part. Based on this platform, a test was conducted on a subsea wellhead connector to illustrate the test process and principle. A numerical calculation using a developed three-dimensional finite element model was performed to compare with the test data. The results of numerical calculation and test have great good agreements. For further application, this synchronous test platform could be used for performance study of the subsea equipment under cyclic load and variable load. This paper is also bringing promotional values for other subsea device with similar and even more complex working condition.
