Safety Controls in Process Operations - Gathering Centers (GC) Booster Stations (BS)

摘要

Gathering Centers (GC) & Gas Booster stations (BS) operations use distinctive process and are subjected to high potential multiple hazards. The Process Safety strategy here, involves combination of Inherent, Passive, Procedural & Active controls for design & safe operation of all the processes. An inherently safer design approach attempts to eliminate potential hazards from the process operation without relying on control measures, systems or human intervention for incident prevention. Risks cannot be completely eliminated from the handling, processing, storage and export of hazardous materials. Instead, the goal of process safety management is to consistently reduce risk to a level that can be tolerated by all concerned- facility staff, company management, and the public at large. A systematic, risk-based approach to safety design can help eliminate hazards that pose intolerable risk from the process and mitigate the potential consequences of hazards. Safety Control in Process Operation is the important hazard control & risk reduction strategy, which falls under the Active control category. This presentation discusses ‘Safety Control in Process Operations’ with special focus on process safety for incident control & prevention in GC & BS facilities. The discussions also touches the Basic Process Control, vis-a-vis Safety Instrumented System (SIS), Layers of Protection, Initiating Events -referring Incident cases, Examples of SIS to Prevent abnormal situation & bring the operation to a safe state, the Safety integrated levels (SILs) & its reliably to ensure the protection.
