Abstract: The present application provides a method, a device, and a system of vibration reduction control on the installation of a deepwater drilling riser. The method includes: determining a lateral vibration displacement of each position of the riser at different times in an installation process according to a mechanical model of the deepwater drilling riser in the installation process, determining a stress generated by a lateral vibration of the riser in the installation process, determining a vibration reduction control speed applied to a bottom of the riser in the installation process according to the stress and the lateral vibration displacement of each position of the riser at different times in the installation process, and performing a vibration reduction control on the bottom of the riser based on the vibration reduction control speed.

Abstract: The present application provides an underwater-wellhead feeding tool assembly and a use method thereof. The device controls a controller to add pressure to an inside of a drive cylinder through a first pipeline via a first port, and to add pressure to a cavity apace between a pressure-bearing cylinder and the drive cylinder through a first branch line; the controller controls, through a third branch line, the drive device to transmit a torque to the underwater wellhead feeding tool, and transmit, through a second branch line, an axial force to the underwater wellhead feeding tool; and then a sensing component transmits a detected stress signal and/or strain signal to a data acquisition device through a test lead, thereby testing and analyzing an effect of different force field conditions on mechanical behaviors and performance of the underwater wellhead feeding tool.
