I PROCESS ALARM-DESIGN AND CHANGE MANAGEMENT PROCESS ALARM MANAGMENT-AN INVESTMENT TOWARDS SAFE AND RELIABLE OPERATIONS MASTER'S THESIS Masters of Technology and Operations Management
Most of the commercial buildings and private homes are configured with a certain number of alarms to deal with emergency situations, such as fire alarms, HVAC fail alarms, theft alarms, water leakage alarms etc. However, for an industrial process plant, all alarms and their configuration parameters collectively feed into a big database. For a typical offshore installation, the alarm database for the integrated control and safety system may consist of 40000 to 150000 alarms which must be
... ich must be monitored. Considering the vastness of an alarm database for a process installation, and the risk of missing critical alarms, there is a need for a regulated and a guided system to handle and integrate all aspects of alarm engineering to create a functional alarm system. Such an alarm system must: • Be built on "principles of alarm design" for process industries • Be complaint with applicable regulations • Be usable by process operators in management of abnormal situations • Perform in line with organisational performance measures As process industries are getting increasingly complex, with new technologies and expansion projects, process operators are becoming overloaded with new systems and new alarms dominate the unnecessary disturbance. Alarm systems need to be well specified and maintained to ensure safe operations.
