Embodiment Construction

[0027] The specific implementation manners of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The described implementation example is only a part of the embodiments of the present invention, not all embodiments. The present invention takes the marine derrick as an embodiment, but it can be implemented and extended to the towering structures of the offshore platform. Therefore, the present invention is used to act on Examples of other high-rise marine structures all belong to the protection scope of the present invention.

[0028] Such as figure 1 Shown is the module connection diagram of the offshore platform derrick condition monitoring and life prediction system. The derrick of the ocean drilling rig is on a floating platform, and the entire drilling platform floats on the constantly changing sea level. Therefore, for offshore platform derrick monitoring, i...

Abstract

The invention, which belongs to the technical field of marine structure monitoring, relates to an offshore platform derrick condition monitoring and fatigue service life prediction system. The systemis composed of a monitoring module, an information collecting and wireless transmission module and a derrick fatigue service life prediction module. The monitoring module consists of a derrick strainand motion response detection module and a wind load and platform motion detection module. Measured data are transmitted to the information collecting and wireless transmission module by means of wireless transmission, wherein the information collecting and wireless transmission module includes a data collection and transmission device; and then the data are transmitted to the derrick fatigue service life prediction module including a data processing and computing module, an alarm device, a receiving / storing device, and a display device, wherein the data processing and computing module and thereceiving / storing device are in bidirectional connection. According to the invention, the way is provided for real-time monitoring and fatigue service life calculation of the offshore platform derrick; the fatigue damage degree of the derrick is determined in real time; the safety of drilling work of the offshore platform is enhanced; and the data support is provided for the new derrick design.

Description

technical field [0001] The invention belongs to the technical field of marine structure monitoring, and in particular relates to a system for monitoring the working condition of an offshore platform derrick and predicting fatigue life. Background technique [0002] The offshore platform derrick is affected by wind, wave, current, earthquake (such as jacket type) and corrosion, which poses a serious threat to the safe operation of the offshore platform, and also aggravates the fatigue damage of the offshore platform derrick. The occurrence of many marine operation safety accidents has caused major economic losses and the ocean has been seriously polluted. Therefore, the systematic monitoring of offshore platforms has become an important issue in research and development. important. [0003] In order to ensure the normal operation of the offshore derrick, it is necessary not only to monitor the safety of the derrick in real time, but also to monitor and evaluate the fatigue d...
