Benefits of technology
"The patent describes a system for capturing evidence of an emergency disconnect sequence on a drilling platform. This system includes a stack screen with an emergency disconnect sequence button, a video capture device, a video card, and a storage device for storing the captured evidence. The system can automatically capture the initiation and progress of the emergency disconnect sequence, providing a record of the events that occurred during the emergency disconnect sequence. This evidence can be used to improve safety and reliability in drilling operations."
Problems solved by technology
However, the availability of land-based production fields is limited.
However, this conventional approach is problematic.
Further, beyond the log, conventional systems may not include any additional tool to verify that the operator initiated the EDS.

Embodiment Construction
[0028]The following description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims. The following embodiments are discussed, for simplicity, with regard to the terminology and structure of an emergency disconnect sequence (“EDS”) system provided with a stack screen for initiating an EDS and / or monitoring the status of that EDS. However, the embodiments to be discussed next are not limited to these systems, but may be applied to other systems (e.g., diverter systems) that may include other interfaces (e.g., alarms screen, diverter screen, events screen, utility screen) for initiating and / or monitoring the status of other sequences (e.g., alarms, diverter sequences, events).

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.
Description
BACKGROUND[0001]1. Technical Field[0002]Embodiments of the subject matter disclosed herein generally relate to methods and systems and, more particularly, to mechanisms and techniques for capturing video evidence of the initiation and / or progress of an emergency disconnect sequence.[0003]2. Discussion of the Background[0004]During the past years, with the increase in price of fossil fuels, the interest in developing new production fields has increased dramatically. However, the availability of land-based production fields is limited. Thus, the industry has now extended drilling to offshore locations, which appear to hold a vast amount of fossil fuel.[0005]The existing technologies for extracting the fossil fuel from offshore fields may use a system 10 as shown in FIG. 1. More specifically, a blowout preventer stack (“BOP stack”) 11 may be rigidly attached to a wellhead 12 upon the sea floor 14, while a Lower Marine Riser Package (“LMRP”) 16 may be retrievably disposed upon a distal ...
