1. Parametric analysis of a phenomenological model for vortex-induced motions of monocolumn platforms
Phenomenological models are an important branch in VIV (Vortex-Induced Vibrations) and in VIM (Vortex-Induced Motions) studies to complement the results achieved via CFD (Computational Fluid Dynamics), as the latter tool is not presently a suitable tool for intense use in engineering analysis, due to high computer power requirements. A phenomenological model

2. Estudo de VIM - Movimentos Induzidos por Vórtices em plataformas do tipo monocoluna: abordagem numérico-experimental e impactos no sistema de amarração. / VIM study - Vortex Induced Motions in monocolumn type platforms: numeric-experimental approach and impact on mooring system.
The vortex induced vibration VIV is a main subject studied in the offshore engineering, having its name adapted to VIM by the occurrence in Spar platforms in the Gulf of México. As the first monocolumn unit, the Sevan Piranema, was in Northeast Brazil in 2007, VIM occurrence in cylindrical units like this was questioned, having the mooring lines design dime

3. Análise dos critérios de estabilidade para projetos de plataformas do tipo monocoluna. / Analysis of the stability criteria of monocolumn type platform design.
To be classified and approved by a classification society, all offshore structures shall be submitted and analyzed according to standard rules. The stability criteria are based on the IMO MODU (International Maritime Organization Mobile Offshore Drilling Units) Code which has reference to almost all types of floating units such as surface, column-stabilized

4. Estudo do moonpool como sistema de minimização de movimento em uma plataforma do tipo monocoluna. / Study of moonpool as a motion minimization device in a monocolumn type platform.
A maioria dos estudos realizados sobre moonpools existentes em embarcações sempre objetivou a redução das amplitudes de oscilação da água interna a estes, pois sua usual utilização é a passagem de linhas de produção, equipamentos e mergulhadores. Estes estudos mostram que com a mudança da geometria interna do moonpool é possível alterar o comp
