Blowout preventer system with data playback

A subsea oil and gas operation analysis system, comprising:

• a database storing data generated based on measurements made by a plurality of sensing devices implements on a blowout preventer;
• a display comprising a user interface;
• at least one processing device having access to instructions that, when executed by the at least one processing device, cause the system to:
• receive the data via the user interface, wherein the data is associated with multiple events having a selected event type;
• determine a time range for each of the multiple events based on the selected event type;
• determine a data variable based on the selected event type;
• obtain, from the database, respective values of the data variable corresponding to the time range for each of the multiple events;
• generate, on the display, a visual representation of the values corresponding to the time range for each of the multiple events, the visual representation providing playback of the values synchronized with respect to time,
• wherein the visual representation of the values includes respective graphs of the data variable for each of the multiple events superimposed with each other, wherein the time range for each of the multiple events is graphed by duration from a start time along a shared time axis, and
• wherein playback of the visual representation sequentially displays the values of the data variable over the time range;
• and
• provide, via the display, a data playback control element, wherein the playback of the values of the data variable is controlled manually or automatically via user manipulation of the data playback control element,
• wherein playback of the values is independently controlled by the position of the data playback control element, such that the values corresponding with a first event of the multiple events are controllable to advance while the values of a second event of the multiple events are kept paused.

A method for subsea oil and gas operation analysis, comprising:

• receiving measurements from a plurality of sensing devices instrumented on a blowout preventer, the measurements generated by the plurality of sensing devices over time;
• storing data generated based on the measurements in a database;
• providing a data playback interface to a client device, wherein the data playback interface includes a data playback control element and the data, wherein the data is associated with multiple events having a selected event type;
• determining a time range for each of the multiple events based on the selected event type;
• determining a data variable selected from a plurality of data variables based on the selected event type;
• retrieving, from the database, respective values of the data variable corresponding to the time range for each of the multiple events;
• generating, on the display, a visual representation of the values corresponding to the time range for each of the multiple events, the visual representation providing playback of the values synchronized with respect to time,
• wherein the visual representation of the values includes respective graphs of the data variable for each of the multiple events superimposed with each other,
• wherein the time range for each of the multiple events is graphed by duration from a start time along a shared time axis, and
• wherein the playback of the values includes sequentially displaying the values over the time range;
• receiving user manipulation of the data playback control element, wherein the data playback control element is manually or automatically controlled;
• and
• displaying the values according to the user manipulation,
• wherein playback of the values is independently controlled by the position of the data playback control element, such that the values corresponding with a first event of the multiple events are controllable to advance while the values of a second event of the multiple events are kept paused.
