Embodiment Construction

[0027] The specific embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS The described implementation examples are only a part of the embodiments of the present invention, not all of the embodiments. The present invention takes an ocean derrick as an embodiment, but it can be implemented and extended to the towering structure of an offshore platform. Therefore, the present invention is used for Other examples of towering ocean structures fall within the protection scope of the present invention.

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

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 particularly relates to an offshore platform derrick working condition monitoring and fatigue life prediction system. Background technique [0002] Offshore platform derricks are affected by wind, waves, currents, earthquakes (such as jacket type) and corrosion, which pose a serious threat to the safe operation of offshore platforms, and at the same time aggravate the fatigue damage of offshore platform derricks. Many marine operation safety accidents have caused major economic losses and the ocean has been seriously polluted. Therefore, the systematic monitoring of offshore platforms has become an important topic of research and development. As the core component of the drilling rig system, platform rig derricks are particularly safe and reliable. important. [0003] In order to ensure the normal operation of the offshore derrick, it is necessary not only to monitor the safety ...
