EEMUA Publication 242 - Proof testing good practice for Instrumented protective systems

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.  

The first edition of this guidance outlines good practice in carrying out proof testing of Instrumented protective systems (IPS) and writing proof testing procedures. EEMUA 242 provides an overview of the high level requirements for proof testing, including the intent behind the tests. Detailed guidance covers the testing of particular instrument types and how to document a proof test in a standard proof test routine template. This publication is intended for site engineers working with system designers on new IPS, but is also helpful for legacy IPS where documentation of the design is incomplete.

The emphasis is on the practical aspects of proof testing, given that every process plant has its own specific requirements and that the ideal of out of service end-to-end testing may rarely be achievable because of operating constraints. EEMUA 242 covers an area which is outside the scope of most standards, and for many users would be a very steep learning curve without guidance. It is based on the experiences of testing real process plant equipment and has been extensively reviewed by industry practitioners.

Applying EEMUA 242 may assist in fulfilling some of the requirements of Clause 16 of IEC 61511-1 which places specific requirements on Safety instrumented functions (SIFs), which are IPS protecting safety hazards with a required integrity of SIL (Safety integrity level) 1 or above. This guidance should be applied to IPS which are SIFs, but may also be applied to other IPS, including those protecting non-safety hazards or those with below SIL1 integrity. Overall requirements for proof testing of IPS and how this is related to the safety lifecycle is established in other documents such as IEC 61511.

EEMUA Publication 159 Digital image

2018, 5th Edition, including Amendment 1

ISBN: 978 0 85931 218 9

EEMUA Publication 159 Above ground flat bottomed storage tanks - a guide to inspection, maintenance and repair

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.

EEMUA Publication 159 is considered to be the most comprehensive users' guide available on above ground vertical cylindrical, steel storage tanks. It is also used worldwide by regulators as an example of what good practice looks like.

EEMUA 159 is intended to assist in the establishment of essential inspection and maintenance requirements in order to minimise in-service problems and extend the useful life of these storage tanks. It offers guidance on tanks built to BS, EN or API standards for the storage of petroleum and chemical feed-stocks and products and refrigerated gases. These standards include BS 2654, API 620 and API 650, DIN 4119-1 and -2, CODRES, G0801 and EN 14015. In addition, since EEMUA 159 contains information on many topics that are not covered in API 653, the EEMUA publication can be considered complementary to the API standard.

This new edition builds on previous work with additional material to reflect the advances in technology, understanding and operational information. Chapters that have been significantly updated include those on corrosion of tanks, general inspection techniques and interpretation of inspection data, fixed roofs, floating roofs, hydrotesting and probabilistic preventive maintenance (PPM). There are also completely new chapters on mothballing, turn-around procedures, aluminium domes and operation at elevated temperatures. Significantly, a new climate code has been added for Arctic conditions. There is also more focus on innovations and new inspection techniques.

The PPM methodology provides what is believed to be the world's only combined theory of risk based inspection (RBI) and reliability centred maintenance (RCM). The different and non-harmonised methodologies of RBI and RCM, since their initiations throughout various aspects of industry (not only storage tanks), have never been combined in the way proposed and implemented in EEMUA 159. The process is time-based, condition-based and reactive. 

The publication sets out key features for planning and executing inspection, maintenance and repair works. It includes descriptions of the key tank components that require inspection and maintenance, degradation mechanisms and common inspection techniques, and details on tank lifting. 

Comprehensive guidance is given on many key design features, on common problems experienced during operation and on repair methods. There are numerous new sections, such as on snow loading, planar tilt and overplating. Appendices offer guidance on how to perform assessment calculations on tank components, illustrated by means of sample calculations, as well as on repair methods.

EEMUA Publication 191 Alarm systems - a guide to design, management and procurement 

Version: Digital/PDF

If you are a user from an EEMUA member company, please log in and download your complimentary digital edition here.

Alarm systems form an essential part of the operator interfaces to large modern industrial facilities. They provide vital support to the operators by warning them of situations that need their attention and have an important role in preventing, controlling and mitigating the effects of abnormal situations. Since it was first published in 1999, EEMUA 191 has become the globally accepted and leading guide to good practice for all aspects of alarm systems. 

  • Providing clear guidance for both existing and new alarm systems
  • Written by alarm systems experts working on high hazard sites
  • Informed by real-world process safety experiences
  • Acknowledged as good practice by leading regulators
  • Aligned with international standards
  • Contributing to plant safety, efficiency and compliance
  • Globally applicable across a wide range of industry sectors

The publication, developed by users of alarm systems with input from the GB Health and Safety Executive, gives comprehensive guidance on designing, managing and procuring an effective alarm system. It is intended to help in improving existing systems and in developing new facilities during plant construction or during alarm system refurbishments. Both of the international standards for the management of alarm systems for the process industries, ISA 18.2 from the International Society of Automation and IEC 62682: 2015, are aligned with EEMUA 191. The new Third Edition has been comprehensively updated and includes guidance on implementing the alarm management philosophy in practice; applications in geographically distributed processes; and performance metrics and KPIs. 

EEMUA 191 is primarily concerned with alarm systems provided for people operating industrial processes. These include alarm systems in industries such as chemical manufacture, power generation, oil and gas extraction and refining and others. However, much of the guidance is generic and with appropriate interpretation can be applied in other sectors. For example, the guide has been used successfully as a basis for training in the rail and transport sectors, in the nuclear industry, and elsewhere.

EEMUA inspection sheets for above ground vertical, cylindrical steel storage tanks (from EEMUA 159 Ed. 5) - Dutch language version

Version: Digital/PDF

EEMUA Publication 159 Edition 5 primarily addresses storage tanks built in accordance with relevant British standards but where appropriate it also refers to and makes use of commonly accepted international standards and codes, such as those of the American Petroleum Institute (API). These differ little in the in-service conditions that they cover and the resulting inspection requirements. Accordingly, EEMUA 159 is intended as a general inspection, maintenance and repair guide applicable to above ground vertical cylindrical steel storage tanks built to standards such as BS 2654, API 620 and API 650, DIN 4119-1 and -2, CODRES, G0801 and EN 14015.

This document represents a minimum of suggested NDT (non-destructive testing) inspection sheets for the elements of steel storage tanks. Use of these inspection sheets is at the risk of the user and EEMUA takes no responsibility for errors or omissions that may be found. These free inspection sheets, used within the context of EEMUA 159, will help ensure that storage tanks are suitably inspected. 

These inspection sheets Include the changes made in Amendment 1 to EEMUA Publication 159 Edition 5 (Imprint 08/2018).

Some key aspects of this EEMUA Checklist are addressed further in EEMUA's Storage Tanks e-learning which is availble in Dutch and English.
