Profile: SIS-Tech Solutions is an engineering company that specializes in offering design and engineering services for safety instrumented systems (SIS). We are experienced in designing SISs that meet the four essential guidelines including regulatory & standards complaint, reliable, operable, maintainable & testable and lowest lifecycle cost. We simplify compliance with IEC 61511 and ANSI/ISA 84.00.01-2004 by integrating the functional safety management requirements with proven project management processes. We are specialized in offering management system policies & procedures, process hazards analysis (PHA) facilitation, auditing, hazard & risk analysis, process requirements specification-independent protection layer (IPL) reconciliation, and safety integrity level (SIL) verification. We provide consultants to build policies & procedures, to train the personnel, and to implement a protective management system for a specific site or for an entire company. We fulfill the documentation and procedural requirements for existing facilities by including a method for documenting that the systems in place provide the required risk reduction. Our hazard and risk analysis (H&RA) encompasses many different types of risk analysis, such as process hazards analysis (PHA), layers of protection analysis (LOPA), quantitative risk assessment (QRA), and consequence modeling. We develop an overall work process using the existing process hazards analysis (PHA) methodologies to screen risks for review using more rigorous techniques. This process provides a means to sieve through process risk, to identify high risk areas, and to deploy the latest analytical techniques. Our Diamond-Sis® is a stand-alone, non-PE logic solver for process industry applications. Rated for -30C to +75C and constructed using Class I Div II components, it can be installed in the process unit even under the harshest conditions near the equipment under control, reducing implementation costs.
