摘要

Systems and methods for replacing equipment at a wellsite, the wellsite having a subsea stripper installed proximate a subsea borehole. The system has at least one seal assembly portion, at least one seal replacement arm and an actuator. The seal assembly portion(s) is (are) positionable in the subsea stripper and replaceable therefrom. The seal assembly portion(s) has (have) a packer extendable within the subsea stripper to form a seal about the subsea stripper. The seal replacement arm(s) is (are) for replacing the seal assembly portion(s) through a door of the subsea stripper. The actuator is for remotely actuating the seal replacement arm(s) to engage the seal assembly portion(s) whereby the seal assembly portion(s) is (are) remotely replaceable.

主权项

1. A replaceable seal assembly for a stripper at a wellsite, the wellsite having a tubing extending through a blowout preventer and into a borehole, the seal assembly comprising:
a carrier divided along a longitudinal axis thereof into at least two longitudinal carrier portions, the carrier operatively connectable to the stripper; a packer positionable in each of the at least two longitudinal carrier portions and extendable therefrom to sealingly engage the tubing; and a pair of bushings positionable in each of the at least two longitudinal carrier portions, the pair of bushings comprising an upper and a lower bushing positionable on opposite sides of the packer to support to the packer therein, each of the pair of bushings comprising an exterior guide and an interior guide, the exterior guide matingly connectable with the interior guide of another of the at least two longitudinal carrier portions.
