MultiFEBE integrates multiple finite element and boundary models for solving linear static time harmonic multi-domain interaction problems within the field of computational mechanics. It allows to couple bounded or unbounded two- three-dimensional continuum inviscid fluids, elastic solids poroelastic media with beam shell structural elements. This paper summarizes numerical methods implemented ...

This study is focused on the wave energy converter of an oscillating water column (OWC) system that integrated with a jacket type infrastructure applied for offshore wind turbine system. In this way, electricity generation by both power and can be conducted simultaneously to maximize utilization sustainable energy. A numerical analysis was performed in research model simulate airflow response e...

Offshore oil and gas industry is blooming up towards the deep-water region of ocean deposit. Far off the continental shelf, the traditional jacket type fixed platform and bottom supported compliant platform are not suited to be economic offshore structure in deep water oil and gas exploration. Floating Spar platform is essentially most economic and efficient in these sea states. In the present ...

In the North Sea, an array of wind profiling wind lidars were deployed mainly on offshore platforms. The purpose was to observe free stream winds at hub height. Eight lidars were validated prior to offshore deployment with observations from cup anemometers at 60, 80, 100 and 116 m on an onshore met mast situated in flat terrain. The so-called “NORSEWInD standard” for comparing lidar and mast wi...

The levels of non-proportionality in fatigue stress-time series are difficult to determine. Approaches from literature not easy interpret and predicts different for variable constant amplitude stresses. In this paper, an extension the PCA-based method is proposed which stresses transformed into equivalent by scaling stress reversal points. This ensures robust easily interpretable results. compa...

Brazil began to explore its seas in the 60’s of XX Century looking for petroleum. This journey Northeast and first oil field produced offshore was Guaricema Field, State Sergipe. During 70’s, Petrobrás found Campos Basin, between States Espírito Santo Rio de Janeiro, that became most important province until discovery Pre-Salt province, Santos Basin. As these fields are producing a long time, m...
