Abstract

The invention discloses a marine riser lateral vibration PD control simulation method which includes conducting discretization on a partial differential equation, then building the Matlab GUI interface on a personal computer to simulate vibration of the riser and collect vibration data of the riser, utilizing a serial port transmission control module to design the PC control algorithm according to the data and converting the algorithm into electric signals which are then transmitted to the PC. By means of the method, the interface can receive control signals transmitted by the control module timely and respond to the control signals quickly.

Description

technical field

[0001] The invention belongs to the field of safe production of marine oil delivery risers, and in particular relates to a PD control simulation method for lateral vibration of marine risers. Background technique

[0002] Ocean oil pipeline is the main form of offshore oil and gas gathering and transportation, which has the advantages of continuous, fast, large transportation volume, and little impact on climate. It connects the upstream and downstream of offshore oil and gas field development, and is the lifeline project in the entire offshore oil and gas field development. At present, offshore oil and gas development (especially the exploration and development of deep water and ultra-deep water oil and gas resources) has become the key field of oil and gas extraction in the world. The safe production of offshore oil and gas resources is of great significance for my country to build sustainable energy and resource areas and maintain national economic securi...
