Wireless remote control type deepwater drilling riser multipoint mechanical synchronous monitoring method

Abstract

The invention provides a wireless remote control type deepwater drilling riser multipoint mechanical synchronous monitoring method. An overwater central control subsystem enters a standby state, and each mechanical synchronous monitoring device of an underwater monitoring subsystem is controlled to enter a dormant state by an underwater monitoring point central control module; and the synchronous monitoring state is configured with a wireless remote control mode and a target measuring point through a platform central control management module, a remote control key instruction word is generated and is sent to an acoustic communication module for sending, the data return state sends a transmission key to each measuring point of the underwater subsystem, and the monitoring information is returned to the acoustic communication module after analysis and then is sent to the platform central control management module. According to the wireless remote control type deepwater drilling riser multipoint mechanical synchronous monitoring method, the remote control capability is designed and applied to riser multipoint mechanical synchronous monitoring by using a wireless communication system, so that a platform central control monitoring worker can customize any one or more customized monitoring according to actual requirements, scientific management and evaluation of the platform integrity can be greatly facilitated, and the fatigue monitoring efficiency and effectiveness of a deepwater platform riser are improved.

Description

technical field [0001] The invention relates to the fields of marine engineering and deep-water petroleum, in particular to a deep-water riser fatigue monitoring method suitable for long-term service. Background technique [0002] In the field of offshore oil, the riser is the throat connecting the subsea wellhead and the offshore operation platform. It is an important weapon for deep-water oil and gas exploration and development, and it is also the most demanding and challenging part of deep-water oil and gas development technology. In recent years, a series of riser fatigue failure accidents have occurred in many areas, which not only reflects the high risk of deepwater oil and gas exploration and development, but also fully demonstrates the necessity and importance of riser fatigue monitoring. The complex dynamic and static response of the riser under the action of waves, ocean currents and internal loads is an important reason for riser failure, especially the alternatin...

Problems solved by technology

However, when the number of monitoring points increases, a complete monitoring data return will take a long time period

In addition, consider the differences in monitoring managers' attention to monitoring information such as different measuring point locations and different monitoring parameters in the application, such as analyzing vibration pairs and mechanical responses at a particular location at a certain moment, or severe weather such as typhoons affecting offshore operations. Impact analysis, etc., the existing monitoring methods lack flexibility and convenience
