Avaliação de procedimentos de descida e transporte de equipamentos para perfuração de poços offshore pela coluna de Riser

Abstract

Due the large demand of products derived from petroleum, the producers were led to search for new reservoirs, exploring offshore zones with water depths over 3000 meters. With the exploitation on deep waters , the process of the equipment installation on the seabed is becoming a critical factor and therefore requires the execution of very detailed numerical simulations and analysis to represent the real scenario faithfully. Another important factor is the transport of these equipments, that can require a lot of time. To constrain this problems, this dissertation uses the BOP stack as a study object. These equipment are used in drilling of wells procedure to ensure its safety. It has large dimensions and can present critical results during the vertical installations and transport operations using the riser column, especially if they are located in resonance zones. The main objective of this work is to study the mentioned procedure and the effects they cause in the riser connected to the equipment.
