MECHANICAL ANALYSIS OF DEEPWATER DRILLING RISER UNDER DIFFERENT OPERATING MODES
ABSTRACT
This article uses the deepwater drilling riser equipped on a specific ocean drilling vessel as an example to establish a dynamic analysis model of the riser, and analyzes the lateral deformation characteristics of the riser under different working conditions and examines the impact of various factors on the lateral displacement of the riser. Research shows that under normal connection modes, maximum deformation occurs at the upper-middle section of the riser. Under suspended evacuation modes, the lateral deformation of the riser exhibits a trend of initially increasing and then decreasing. Ocean current velocity is one of the primary influencing factors on the lateral vibration characteristics of the riser.
