Abstract: The disclosure presents systems and methods for hot swapping pumps at a wellsite while minimizing the impact to the pumping operations. As one pump is swapped out, such as for maintenance, the remaining pumps in the set of pumps at the wellsite can continue pumping operations. In some aspects, the swapping of pumps can be performed by a user using a protection barrier to isolate the pump location where the pumps will be swapped. In some aspects, one or more of the steps to swap pumps can be performed through automation thereby minimizing danger to a user. In some aspects, the pump being located at the pump system can be primed and pressure tested prior to be located to improve the time to enable the pump for pumping operations.

Abstract: A BOP stack encapsulation system has dual partially hemispherical dome sections which are each supported and guided for linear movement to open and closed positions relative to base plate. The dual containment domes are moved from open positions to closed and hermetically sealed positions about a BOP stack responsive to sensing BOP leakage or a dangerous pressure condition and are controllable from a remote location. When both containment domes are closed they develop concentrically arranged dual hermetically sealed spaces that enclose the BOP stack and capture any leaked fluid and pressure. Captured well fluid constituents can be bled from the internal spaces of the concentric encapsulation domes as desired.
