Abstract

La descripción proporciona un sistema preventor de explosiones (BOP) con un ariete (12) que tiene una hoja de cizalla con un perfil de hoja de cizalla (21) para cizallar un miembro tubular (20) que está dispuesto en el BOP; el perfil de hoja de cizalla puede incluir un concentrador de tensiones (24) y una superficie de centrado configurada (26); el concentrador de tensiones y la superficie de centrado configurada pueden estar descentrados lateralmente de una línea central del recorrido del ariete y en lados opuestos de la línea central; una segunda hoja de cizalla opuesta puede tener una imagen de espejo del perfil de hoja de cizalla con el concentrador de tensiones y la superficie de centrado configurada invertidos con relación a la orientación de la primera hoja de cizalla; además, el ariete puede incluir un mandril con un perfil de mandril alrededor del cual se deforma el miembro tubular durante el procedimiento de cizallamiento y para reducir un ancho lateral general del miembro tubular cizallado en el agujero pasante del BOP para permitir la recuperación del miembro tubular cizallado y deformado del BOP.
