What are the changes in API RP 754?

The American Petroleum Institute (API) issued the second edition of “Recommended Practice (RP) 754: Process Safety Performance Indicators for the Refining and Petrochemical Industries.” The API RP 754 committee hopes the updated edition of the standard serves as an even more effective tool for all parties interested in learning from and preventing process safety events (PSEs). Tracking of PSEs, as defined within RP 754, and analysis of the aggregate data required for reporting is the first step in identifying corrective actions to prevent recurrence.

What are the differences in API Plan 62 and API Plan 53a?

A seal support system can be configured in a number of ways — generally following designs suggested by the American Petroleum Institute (API). When making a selection, the user should consider the potential effect on hygiene standards, the cost to operate and the level of maintenance expected. Two simple forms of seal support systems are API Plan 62 and API Plan 53a

How does ANSI/ISA76.00.02 benefit instrumentation?

ANSI/ISA76.00.02, "NeSSI Generation II — Smart Systems and Communications Bus," defines a communication structure that enables the sample conditioning system to evolve from a mechanical component in the field requiring physical monitoring to a control element providing feedback for the benefit of the process.

What are API-610 specifications for head tolerances of centrifugal pumps?

The oil and gas industry heavily relies upon centrifugal pumps designed to meet API-610 specifications. Familiarity with the pump head tolerances allowed under API-610 is necessary to avoid disappointment with the performance of the purchased pump and additional costs due to rework.

How does IEC 61511 differ from ANSI/ISA 84.00.01-2004?

IEC 61511, “Functional Safety — Safety Instrumented Systems for the Process Industry Sector,” is the replacement for the current U.S. national standard, ANSI/ISA 84.00.01-2004. Unlike the previous edition, the latest U.S. and international versions don’t differ at all. However, many U.S. processors may worry about what happened to the previous edition’s “grandfather clause” or ANSI/ISA 84.00.01-1 clause 1y.
