Structural reliability analysis of offshore jackets for system-level fatigue design
نویسندگان
چکیده
Lattice systems such as offshore jackets and towers are weight-efficient support structures for wind energy oil gas units. Nevertheless, their light-weight is achieved at the expense of increasing proneness to fatigue failure, due many welded connections. Consequently, special attention be dedicated design hot spots. System-level methods aim calibrating reliability components achieve a desired target system reliability. These rely on accurate assessment probability which computationally demanding statistical dependence among limit states large number possible deterioration that need taken into account. In present paper, we develop novel approach, called truncation algorithm, estimate lower upper bounds extreme environmental within feasible computational time. The proposed approach applied assessing existing system-level study effects, effects redundancy correlation

Structural System Reliability Framework For Fixed Offshore Platforms
The main objective of this project is to develop a generic framework which will set the basis for achieving more consistent system reliability assessments. The main steps involved in a system reliability assessment, together with the key technical and philosophical issues, will be identified and examined. Their interrelations and relative significance will be assessed in order to link them toge...

یک شکاف باریک در دیواره پهن موجبر مستطیلی به کمک روش ممان تحلیل شده است . در این روش اثر القای مجدد روی دیواره ها و ضخامت دیواره موجبر لحاظ شده است . در واقع روش ممان برای حل یک جفت معادله انتگرالی- حاصل از شرایط مرزی و بکمک توابع گرین - بکار رفته است . در نتیجه حل این دو معادله، مولفه مماسی میدان الکتریکی روی سطوح بالایی و پایینی شکاف بدست آمده است . این میدان ها با یک سری تابع سینوسی بسط شده ...
15 صفحه اولHuman reliability analysis of an offshore emergency blowdown system.
An offshore platform depressurisation (blowdown) system was designed such that control in emergencies necessitated operator actions over a short space of time. The system design for these operations was analysed using a simple and pragmatic human reliability approach, embedded within a comprehensive risk assessment. The human reliability analysis identified several ways in which human actions c...
