Development And Application Of Safety Load Detection System For Jack Up Drilling Platform

Offshore platform structure is the important infrastructure of the development of offshore oil resources,and the base of offshore production and living,under the influence of environment is very complex and poor,offshore platform structure intensity attenuation is very obvious.Failure damage for the offshore platform,not only caused great economic losses and casualties directly,also may cause serious environmental pollution and social political influence.Shengli offshore drilling company has five jack-up drilling platforms used more than 30 years,the aging serious,and hull has amounted to less than the design bearing capacity and strength index.After introduction,with the development of marine drilling technology and drilling technology,the company had to increase a lot of facilities,platform has been severely overweight,combined with the rise and fall system used of 30 years,platform pile tooth has been squeezed into a wedge.Meshing of gear and rack is irregular,even by rolling into sliding,several times appeared broken teeth,causing platform tilt,in an extremely dangerous state.Real-time and accurately grasp the platform load for aging platform,is particularly important.In this paper,through the project research work " development and application of safety load detection system for Jack-up drilling platform",using of practical ocean engineering feedback and abundant survey data,through advanced detection means to measure the stress of pile legs and dynamic gear load information,use the independent research and development of professional software systems,refer to various platform security carrying data,alarm when platform bearing is too large,achieve the purpose real-time detection and analysis of jack-up drilling platform safety load.Through the use of advanced detection means for real-time dynamic monitoring platform of load change,grasps various states when working platform big load change and early warning,to prevent overweight or overload operation.Therefore,to ensure the safety of jack-up platform used for many years,has extremely important practical significance.
