Definitions

  • the present disclosure relates generally to fluid flow members carrying fluids for industrial processes, and more particularly to systems and methods for operating rams to contain leaks of the fluid flow members.
  • Embodiments of the present disclosure provide systems and methods that can contain the leak and isolate the leak until further repair can be completed safely, with minimum interruption to the flow rate. These systems and methods will isolate the leak so the industrial process can continue until operating conditions are more conducive to shutting down or reducing operations. Embodiments of this disclosure can also allow safe handling of a hydrocarbon well that has experienced a leak, by allowing personnel to get close to the wellhead without getting exposed to the leak discharge.

Abstract

L'invention concerne un système et un procédé servant à assurer l'étanchéité autour d'un élément d'écoulement de fluide, le système et le procédé faisant appel à un ensemble de fermeture à vérin. L'ensemble de fermeture à vérin comporte une chambre d'étanchéité présentant une forme généralement cylindrique lorsque l'ensemble de fermeture à vérin est en position fermée. Un ensemble vérin est situé au niveau d'une extrémité de la chambre d'étanchéité. L'ensemble vérin comporte deux vérins, chaque vérin comportant une surface de mise en prise, la surface de mise en prise étant dimensionnée et profilée de manière à assurer l'étanchéité autour de l'élément d'écoulement de fluide. L'ensemble vérin comprend également un ensemble bras de commande relié à l'un des vérins et un corps de vérin. Les deux vérins sont fixés de manière rotative sur le corps de vérin.
