    Description

    The alarm system supports the rig crews decisions making to ensure the safety of personnel, environment, equipment and efficiency of processes. It is designed with focus on layout and functionality. In situations where the crew is flooded with alarms, the system helps by routing and prioritizing the tasks and by giving additional information and guidance.

    The alarm banner is always visible at the top of the operators screen presenting the  most important  alarm, based on status, priority and chronology. It contains a shortcut button  to the alarm list.

    Generation 
    Alarms are defined as abnormal situations which require corrective action:

    • All alarms are prioritized and categorized
    • Bold text for new alarms
    • Color coding distinguish alarms based on priority
    • Alarm routing ensures only relevant alarms appear in the users main list
    • Several alarm views
    • Improved filtering and sorting

    Alarm Statistics (Option)
    NOV Alarm Statistics offer leading performance indicators by reducing complex alarm logs to explanatory metrics for easy interpretation. Powerful tools enable pinpointing problematic alarms and the underlying causes. Rich reporting options provide a multitude of options for disseminating relevant information to other parties.

    Additional alarm info (Option)
    Right-clicking an alarm in the alarm list to access additional alarm info, including trigger cause, consequence if not corrected and suggested corrective action.

    Features/Benefits

    Cyberbase alarm system supports:

    • Alarm priority (high, medium, low)
    • Alarm routing
    • Automatic locking of noisy alarms
    • Manual alarm shelving

    Audible alarm

    • All high and medium priority alarms have a short audible announcement to alert  the operators
    • The most important high alarms trigger an alarm horn which require silence acknowledgement

    Logging

    • All alarms and events are logged
    • Full description of alarm and time of generation
    • Full description of shelving status and time of update
    • Searchable 7-day history
    • Older alarms are exported to a csv file

    Alarm Statistics (option)
    Alarm Statistics displays a list of key performance indicators, providing a quick overview of the alarm systems performance. The indicators are designed to give a cursory glance into all aspects of the alarm system and for drilling down into the details of each metric. Typical KPIs are average alarm rate, maximum alarm rate and standing alarms.

    Alarm Statistics reporting aggregates alarms in predefined charts and summaries, eliminating the need for sifting through endless pages of alarm logs. Examples of reports are alarm summary, shelved alarms and nuisance alarms. The reports can be distributed to interested parties and be used to demonstrate the performance of the alarm system to auditors and regulators.

    NOV training provides rig specific training.
