(EN) BLOW OUT PREVENTER BONNET HANDLING APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE MANIPULATION DE CAPOT DE BLOC OBTURATEUR DE PUITS
Abstract
(EN)
A blow out preventer bonnet removal method is provided for removing a bonnet from the body of a blow out preventer. The method includes attaching a rail system to the body that extends laterally away from the body. A carriage apparatus is mounted on the rail system. A saddle is connected to the bonnet. The bonnet is then detached from the body. The bonnet is then moved on the rail system from a first position next to the body to a second position spaced away from the body. The carriage apparatus transports the bonnet upon the rail system when moving from the first to the second position.

L'invention concerne un procédé d'enlèvement d'un capot de bloc obturateur de puits, permettant d'enlever un capot à partir du corps d'un bloc obturateur de puits. Le procédé consiste à fixer au corps un système de rail qui s'étend latéralement en partant du corps. Un appareil de transport est monté sur le système de rail. Une selle est reliée au capot. Le capot est ensuite détaché du corps. Puis le capot est déplacé sur le système de rail, d'une première position proche du corps à une seconde position éloignée du corps. L'appareil de transport transporte le capot sur le système de rail lors du déplacement de la première à la seconde position.
