Emergency disconnect sequence timer display and method

Abstract

The invention relates to an emergency disconnect sequence timer display and a method. A rig control interface, system, and method. The rig control interface includes an emergency disconnect sequence button configured to initiate an emergency disconnect sequence signal to be sent to multiplex pods resulting in an emergency disconnect sequence 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 emergency disconnect sequence timer display triggered by initiation of the emergency disconnect sequence signal, the emergency disconnect sequence timer display configured to indicate one or both of time elapsed after initiation of the emergency disconnect sequence signal and a status of the plurality of functions being performed by the devices in the one or both of the lower marine riser package and the blowout preventer stack.

Description

technical field [0001] Embodiments of the subject matter disclosed herein relate generally to methods and systems, and more specifically, to mechanisms and techniques for indicating the time elapsed since an emergency disconnect sequence was initiated. Background technique [0002] The interest in developing new production fields has grown significantly over the past few years as fossil fuel prices have climbed. However, land-based product fields have limited availability. As a result, the industry today extends to drilling wells in offshore locations that appear to hold large quantities of fossil fuels. [0003] Existing techniques for extracting fossil fuels from offshore oil fields may use the system 10 shown in FIG. 1 . More specifically, a blowout preventer stack ("BOP stack") 11 may be rigidly attached to the wellhead 12 on the seabed 14, while a subsea riser assembly ("LMRP") 16 is 20 or any other type of surface drilling platform or vessel extending the far end of...

AI Technical Summary

Problems solved by technology

However, this conventional approach is problematic

For example, if the operator mistakenly records the time when the EDS button was pressed, forgets to record the time, or refers to the wrong part of the document, the operator may not be able to accurately measure the progress of different functions and may not be able to accurately determine when the EDS is complete

This can cause additional problems, such as waiting a long time to check that EDS is complete

Furthermore, this conventional method is tedious for the operator, since both recording the time of pressing the EDS button and referencing the document 66 require the operator's attention
