Abstract

sistema de controle de bop submarino, e, método para comutar uma válvula principal. trata-se de um conjunto de afogamento ativável que é disposto em comunicação com um manifolde de função de bop. o conjunto de afogamento pode ser colocado antes de um ponto de distribuição (pod). o conjunto de afogamento pode ser ativado para amortecer a aceleração ou desaceleração do fluido hidráulico no manifolde de função de bop.subsea bop control system, and, method for switching a main valve. This is an activatable choke assembly that is arranged in communication with a bop function manifold. the choke assembly can be placed before a distribution point (pod). The choke assembly can be activated to dampen the acceleration or deceleration of the hydraulic fluid in the bop function manifold.
