Abstract Accuracy in analysing the integrity of a structure is critical for determining structure’s fitness service and reliability status. Today, variety techniques approaches are applied, including use data science applications. Data synthesis computer science, mathematics, statistics. Meanwhile, susceptible to mix statistical technical design uncertainties that may remain flexible as long ca...

In the seismic risk assessment of structures, two main random variables are involved, namely the vulnerability of the structure and the seismic action. The aim of the study presented here is to analyze the seismic behavior of the jacket-type offshore platforms as an expensive and vital structure. Furthermore, the influence of the incidence angle of the seismic action is also investigated by usi...

Structural optimization of offshore wind turbine structures has become an important issue in the past years due to the noticeable developments in offshore wind industry. However, considering the offshore wind turbines’ size and environment, this task is outstandingly difficult. To overcome this barrier, in this paper, a metaheuristic algorithm called Enhanced Colliding Bodies Optimization...

Development of a numerical model which describes launching of offshore jackets from barge is presented in this paper. In this model, in addition to capabilities of commercial softwares, water entry forces on jacket members and an implicit Newmark solution technique are included. The results are in general agreement with other numerical software’s available (SACS). Fluid forces acting on jacket ...

Abstract The unwanted vibrations of offshore structures induced by wave or earthquake loads can lead to the reduction service life and fatigue failure platforms. This paper introduces tuned inerter damper (TID) a jacket platform as passive control device for mitigating excessive structure loads. An analytical design method is proposed platforms influence installation location on modal response ...

marine industry requires continued development of new technologies in order to produce oil. an essential requirement in design is to be able to compare experimental data from prototype structures with predicted information from a corresponding analytical finite element model. in this study, structural model updating may be defined as the fit of an existing analytical model in the light of measu...
