Risk-Based Inspection, Second Edition (Recommended Practice)

API Recommended Practice 580 provides users with the basic elements for developing, implementing and maintaining a risk-based inspection (RBI) program. It provides guidance to owners, operators, and designers of pressure-containing equipment for developing and implementing an inspection program. These guidelines include means for assessing an inspection program and its plan. The approach emphasizes safe and reliable operation through risk-prioritized inspection. A spectrum of complementary risk analysis approaches (qualitative through fully-quantitative) can be considered as part of the inspection planning process. RBI guideline issues covered include an introduction to the concepts and principles of risk-based inspection for risk management; and individual sections that describe the steps in applying these principles within the framework of the RBI process include:

• understanding the design premise;
• planning the RBI assessment;
• data and information collection;
• identifying damage mechanisms and failure modes;
• assessing probability of failure;
• assessing consequence of failure;
• risk determination, assessment and management;
• risk management with inspection activities and process control;
• other risk mitigation activities;
• reassessment and updating;
• roles, responsibilities, training and qualifications;
• documentation and record-keeping.

Inspection of Pressure-relieving Devices, Third Edition (Recommended Practice)

API Recommended Practice 576 describes the inspection and repair practices for automatic pressure-relieving devices commonly used in the oil and petrochemical industries. As a guide to the inspection and repair of these devices in the user’s plant, it is intended to ensure their proper performance. This publication covers such automatic devices as pressure-relief valves, pilot-operated pressure-relief valves, rupture disks, and weight-loaded pressure-vacuum vents.

The scope of this RP includes the inspection and repair of automatic pressure-relieving devices commonly used in the oil and petrochemical industry. This publication does not cover weak seams or sections in tanks, explosion doors, fusible plugs, control valves, and other devices that either depend on an external source of power for operation or are manually operated. Inspections and tests made at manufacturers’ plants, which are usually covered by codes or purchase specifications, are not covered by this publication.

This publication does not cover training requirements for mechanics involved in the inspection and repair of pressure-relieving devices. Those seeking these requirements should see API 510, which gives the requirements for a quality control system and specifies that the repair organization maintain and document a training program ensuring that personnel are qualified.

Venting Atmospheric and Low-pressure Storage Tanks, Sixth Edition (Identical Adoption of ISO 28300:2008)

Sixth edition of API Std 2000 was published in November 2009 by API. It adopts international standard ISO 28300 into API.

This International Standard covers the normal and emergency vapour venting requirements for aboveground liquid petroleum or petroleum products storage tanks and aboveground and underground refrigerated storage tanks, designed for operation at pressures from full vacuum through 103,4 kPa (ga) [15 psig]. Discussed in this International Standard are the causes of overpressure and vacuum; determination of venting requirements; means of venting; selection, and installation of venting devices; and testing and marking of relief devices.

This International Standard is intended for tanks containing petroleum and petroleum products but it can also be applied to tanks containing other liquids; however, it is necessary to use sound engineering analysis and judgment whenever this International Standard is applied to other liquids.

This International Standard does not apply to external floating-roof tanks.

This edition of API Std 2000 is the identical national adoption of ISO 28300:2008, Petroleum, petrochemical and natural gas industries-Venting of atmospheric and low-pressure storage tanks.

Piping Inspection Code: In-service Inspection, Repair, and Alteration of Piping Systems, Third Edition

In November 2009 American Petroleum Institute (API) published third edition of API 570.

API 570 covers the inspection, rating, repair, and alteration procedures for metallic and FRP piping systems and their associated pressure relieving devices that have been in-service.

The intent of this code is to specify the in-service inspection and condition-monitoring program that is needed to determine the integrity of piping. That program should provide reasonably accurate and timely assessments to determine if any changes in the condition of piping could possibly compromise continued safe operation.

API 570 was developed for the petroleum refining and chemical process industries but may be used, where practical, for any piping system. It is intended for use by organizations that maintain or have access to an authorized inspection agency, a repair organization, and technically qualified piping engineers, inspectors, and examiners.

Tank Inspection, Repair, Alteration, and Reconstruction, 4th Edition

Published by American Petroleum Institute (API) on March 1. This 154 page publication convers carbon and low alloy steel tanks build to API Std 650 and its predecessor, API Spec 12C.

API 653 provides minimum requirements for maintaining the integrity of welded or riveted, atmospheric pressure, aboveground storage tanks after they have been placed in service. It covers the maintenance inspection, repair, alteration, relocation, and reconstruction of such tanks. The scope of this publication is limited to the tank foundation, bottom, shell, structure, roof, attached appurtenances, and nozzles to the face of the first flange, first threaded joint, or first welding-end connection.

This standard employs the principles of API 650; however, storage tank owner/operators may apply this standard to any steel tank constructed in accordance with a tank specification

This standard is intended for use by organizations that maintain or have access to engineering and inspection personnel technically trained and experienced in tank design, fabrication, repair, construction, and inspection.

This standard does not contain rules or guidelines to cover all the varied conditions which may occur in an existing tank. When design and construction details are not given, 05 and are not available in the as-built standard, details that will provide a level of integrity equal to the level provided by the current edition of API Std 650 must be used.

This standard recognizes fitness-for-service assessment concepts for evaluating in-service degradation of pressure containing components. API RP 579, Recommended Practice for Fitness-for-Service, provides detailed assessment procedures or acceptance criteria for specific types of degradation referenced in this standard. When this standard does not provide specific evaluation procedures or acceptance criteria for a specific type of degradation or when this standard explicitly allows the use of fitness-for-service criteria, RP 579 may be used to evaluate the various types of degradation or test requirements addressed in this standard.
