Issues regarding the installation of SIS
Thread Content
Hello everyone. As the security situation continues to improve, it is required that various organizations actively upgrade their SIS systems. So, how should one implement an SIS system?
SIS is a safety instrument system, in which the instruments are installed in accordance with the requirements specified in the user manual.
I mean, how are the points for the safety instrument system determined, and which ones are mandatory?
Serial I/O is controlled by SIS; it’s not mandatory for you to use it, so why go through the hassle of using it? a double-edged sword
**The General Administration of Work Safety requires the use of SIS for certain hazardous chemical processes, but the detailed design for this is carried out by design institutes.
Safety systems are necessary, without a doubt. The general process for establishing or adding new processes is as follows: 1. The design institute determines the logical outline of the system’s scope and functional requirements, and uses this to prepare the technical specifications for the bidding process ； 2. Identify potential suppliers, and determine the final hardware provider through bidding processes ； 3. Submit the logic diagram represented by the SAMA diagram along with other necessary documents to the hardware supplier for development ； 4. Complete the installation under the guidance of the hardware supplier.
We are in the oil and gas storage and transportation business. It actually depends on the specific situation: some oil fields use DCS exclusively, while others combine DCS with SIS systems. It depends on which design firm is responsible for the design, as there seems to be no fixed rule. Moreover, the complexity of SIS systems also varies. In the design of many systems, the SIS system is well-developed, but once it is put into use, many functions are forced to be disabled.
The design institute has not carried out any designs before; it has only worked on some technical improvement projects. Please send me a picture of the SIS.
