Abstract
A BOP booster assembly is provided for use with BOPs that utilize hydraulic actuators mounted in BOP end caps to open the BOP for replacement of the shearing members. The booster assembly has three main components comprising a booster housing, piston, and end plate. An extension in the booster housing is sufficiently long to position the booster hydraulic cylinder axially outside of the ends of the bonnet end caps of the BOP with respect to the wellbore. The booster piston is equal in diameter or larger than the operating piston of the BOP. The operating pistons and booster pistons move simultaneously, in sync, and the same distance for closing and cutting. In one embodiment, an internal hydraulic line is provided in the booster cylinder wall.
