How can safety instrumented systems (SIS) provide reliability for facilities in oil and gas industry?

A safety instrumented system ensures that the employer's small investment in this kind of system will keep the workspace free from accident which in turn will effect productivity. It also ensures that there are less legal percussion, accidental damage compensations, employee health damage and governmental sanctions to think about. All in all this is a small price to pay for the greater good.

Generally instrumented systems fail and require change. For the above it is recommended to have redundant systems that can control automatically remote primary, remote secondary manual, and finally in site step by step. In addition to having at least two signal control systems.

Safety Instrumented system can provide system failures conditions and it can prevent accidents with emergency shutdown the plant.

Safety is the most critical concern in Oil and Gas industry.It is about company’s reputation and sustainability. Oil & gas operators spend a major amount of CAPEX and OPEX budgets insuring plant, personal and equipment safety. The key element of any successful Safety Instrumented system (SIS) is a direct function of its availability, reliability and integration with the plant’s central control system. SIS if not integrated seamlessly can result in reduced operator efficiency leading to increased downtime and operational risk.

we should have a redundancy every where, in the processor it is required to be voting processor and execute the process and make a voting between the results.

for the transmitter also we should have a redundancy.
