Title in Portuguese
Análise dinâmica da operação de resgate lateral de oleoduto submarino.
Keywords in Portuguese
Estruturas subaquáticas
Abstract in Portuguese
O problema dinâmico é considerado como uma perturbação de cada uma das configurações de equilíbrio estático, assumidas pela tubulação, no decorrer da operação de resgate. Ele é formulado e discretizado através de elementos finitos. São discutidos tópicos importantes associados: um modelo dinâmico simplificado é proposto para estudo do comportamento do sistema, quando o cabo fica frouxo, e um critério dinâmico é estabelecido para análise da estabilidade da posição de equilíbrio.

Abstract in English
The dynamics problem is assumed to be a perturbation of each static equilibrium configuration held by the pipeline during the recovery operation. Its formulation and discretization by means of finite elements are presented. Important related topics are discussed: a simplified dynamic model is proposed to study the behavior of the system when the cable becomes loose and a dynamic criterion is established to analyze the stability of the equilibrium position.
