Abstract
A blowout preventer (BOP) stack module includes a chassis core having a module frame, wherein the chassis core supports one or more submodules each configured to perform a function of a BOP stack, an underwater vehicle coupling hardware coupled to the chassis core, wherein the underwater vehicle coupling hardware couples with an underwater vehicle configured to transport and selectively couple and uncouple the BOP stack module relative to the BOP stack, and a mechanical connector coupled to the chassis core, wherein the mechanical connector couples to a stack frame of the BOP stack, and at least one port coupled to the chassis core, wherein the at least one port is a fluid port, a hydraulic port, a pneumatic port, an electrical port, or a combination thereof, wherein the at least one port couples with a corresponding port of the BOP stack.
