5. 1. What is CAMS for HIS (Human Interface Station)?
Stands for Consolidated Alarm Management System
Consolidation of real-time alarms
Acquired from DCS(CS 3000), SIS(ProSafe-RS), AMS(PRM), NCS/PLC(STARDOM )
Consolidation of historical alarms and events
A&E and SOE
Consolidation of alarm-related applications
Alarm design
Real-time monitor
Historical viewer
Change management
Statistical analysis and report
To deliver the necessary alarms to the right person at the right time
Self explanatory slide.
Intentionally deleted EEMUA (to avoid unnecessary discussion at this stage) EEMUA shall be referred to in Day 2 when explaining CAMS in detail.

7. 3. Feature functions of CAMS for HIS
Acquisition: Acquiring all available A&E online real-time
Normalization: Removing dialect or mismatch of information
Re-classification: Re-classifying alarms or events
Alarm prioritization: Prioritizing alarms based on purpose &
consequence
Attribute addition: Adding identifiers and value-added information
Grouping: Unifying redundant alarms
Suppression: Suppressing nuisance alarms
Filtering: Extracting necessary alarms
Sorting: Sorting alarms based on urgency or importance
Eclipsing: Integrating repeated alarm in a single line
Shelving: Shelving unnecessary alarms temporarily
Load shedding: Activating predefined filter automatically in case of alarm flooding
Please explain each of following functions.
Please also mention that the functions in the box will be also mention in the Event analysis presentation following this one using Ehra FPSO data.

8. Acquisition
Acquisition: Acquiring various types of alarms and events from sub-systems
Types of alarms
DCS (Process alarms, System alarms, etc..)
SIS (Safety related alarms)
Asset management system (Field device alarms)
Network Control System (Process alarms)
Types of interfaces
Proprietary control bus interface
OPC A&E
Serial port logger (under consideration)
FTP (under consideration), etc.

9. Normalization & Re-classification
Normalization: Removing dialect or mismatch of information
Data arrangement
Standardizing terminology (e.g. High, HI, H+)
Level of alarm priority
Level of plant hierarchy, etc.
Re-classification: Re-classifying alarms or events
Examples
Correct events that were incorrectly classified as alarms
Vice versa

10. Attribute Addition
Attribute addition: Adding identifiers and value-added information
Identifiers
Purpose: safety, environmental, financial
Consequence: very large, large, medium, small
Time to respond: urgent, quick, routine
Plant hierarchy: plant, area, unit, line
Alarm priority: critical, high, medium, low, logging
Type of user: operator, maintenance, production staff
Value-added information
Reason of alarm occurrence
Role-based action to be taken
Past action

11. Eclipsing Eclipsing: Integrating repeated alarm in a single line
Chattering alarms can be visually hidden.
Alarm shown after Eclipsing will be the one with the highest priority and latest time stamp.

12. Grouping & Suppression
Grouping: Unifying redundant alarms
Same alarms acquired from different sub-systems
Suppression: Suppressing nuisance alarms
Suppressing obvious alarms statically (e.g. alarms generated by stopping plant)

13. Filtering & Sorting Filtering: Extracting necessary alarms
By timestamp, plant hierarchy, alarm priority, user name, purpose, consequence, etc.
Sorting: Sorting alarms based on urgency or importance
By timestamp, alarm priority, time to respond, etc.

14. Examples of Filters SIS: Alarms from SIS
Field devices: Alarms from PRM
Stardom: Alarms from Stardom
System: DCS system alarms
Process: DCS process alarms
Plant A: Alarms in plant hierarchy
Alarm Priority: High/Medium/Low
Time to Respond: Urgent/Quick/Routine
Purpose: Safety/Environmental/Financial
Operating Shifts: Alarms in each shift
Start Up: Important/Unimportant
Combination filter also can be created.
If you have a time, please demonstrate dynamic filter function (Combination filter).

15. Shelving Shelving: Moving unnecessary alarms to the shelf temporarily
Examples of shelving functions
One-shot: Moving unimportant alarm into a shelf one by one.
Continuous: Moving unimportant alarms into a shelf once, then repeated alarms are automatically moved for certain periods or by certain clock time.
Automatic: Assigning one of existing filters as a condition of shelving, then relevant alarms are automatically moved for certain periods or by certain clock time.

16. Load Shedding
Load shedding: Activating predefined filter automatically in case of alarm flooding
If 100 alarms has happened within 60 sec, then automatically select high priority filter. (This is the default setting and can be configured per customer preference.)
