Abstract
A blowout preventer (BOP) stack module includes a chassis core including a module frame, a remotely operated underwater vehicle (ROV) coupling hardware coupled to the chassis core, wherein the ROV coupling hardware couples with an ROV configured to transport and selectively couple and uncouple the BOP stack module relative to a BOP stack, a mechanical connector coupled to the chassis core, wherein the mechanical connector couples to a stack frame of the BOP stack, an electrical BOP component coupled to the chassis core, wherein the electrical BOP component performs one or more electrical BOP functions of the BOP stack, and an electrical connector coupled to the chassis core and the electrical BOP component, wherein the electrical couples to a corresponding electrical connector of the BOP stack or an adjacent BOP stack module.
