Emergency Disconnect Sequence Video Capture and Playback

Abstract

Emergency disconnect sequence (EDS) video capture systems and method. The EDS video capture system includes a stack screen on a drilling platform, the stack screen including an EDS button to initiate an EDS signal to be sent to multiplex pods resulting in an EDS including a plurality of functions being performed by devices in one or both of a lower marine riser package and a blowout preventer stack, and an EDS function status indicator. The indicator is either a video capture device aimed at the stack screen to automatically capture one or more of the initiation of EDS signal by the EDS button and a progress of the EDS indicated by the EDS function status indicator as EDS evidence or a video card to capture one or more of the initiation of the EDS signal by the EDS button and a progress of the EDS indicated by the EDS function status indicator as EDS evidence, and a storage to store the EDS evidence.
