This paper examines the unified dissipative performance of Offshore Steel Jacket Platforms (OSJPs) which include actuator failures and probabilistic delays, through a resilient reliable sampled-data controller. In detail, random variables fetching Bernoulli distribution are treated in particular for stochastic time-delays. By implementing Lyapunov–Krasovskii functions(LKF) together with Second ...

Abstract Rehabilitation, upgrading, or strengthening of structural members, especially columns, has become the target many researchers because columns are most important members in a building and failure causes direct collapse building. This study aims to get an assessment best pattern steel-framed jacket used for axially loaded concrete by numerically studying behavior column different cases s...

the sirri jacket offshore platform was designed and installed in persian gulf of iran in 1975 and has been in service since that time. the importance of offshore structure's stability and the failure of this kind of structure during an earthquake in different active zones revealed that earthquake loading has to be considered. in this paper, magnetorheological (mr) fluid dampers have been propos...

Decommissioning offshore platforms present unique safety and health challenges to the oil gas industry. In Malaysian waters, there are over 300 fixed jacket platforms, most of them exceeded design service life 25 30 years. One key that determine method removal aged is subsea cutting techniques. As underwater a challenging expensive task, it very much essential develop cost-effective techniques ...
