EEMUA Publication 227 Management of ageing electrical assets

Version: Digital/PDF

A hard copy version is also available.

EEMUA Publication 227 aims to provide a coherent, proactive system for managing certain ageing electrical assets.

Electrical equipment is often designed with a relatively long lifetime (typically 20 years) and the electrical engineer responsible for it has the challenge of ensuring the equipment’s integrity over this period, if not well beyond it. In justifying the continued service of equipment, the engineer has to take commercial (reliability, availability, replacement costs) and safety considerations into account. This is a difficult task, and in addition to general good asset management practice, the electrical engineer requires specific guidance relating to:

• Identifying potential failure mechanisms on ageing electrical assets;
• Methods of detecting early signs of failure mechanisms;
• Ways of calculating remaining expected life of electrical assets;
• Maintenance methods to extend electrical asset life; and
• Demonstrating the benefits of replacing equipment before failures occur.
 
This publication is focused on six types of electrical equipment that the EEMUA Electrical Committee prioritised as those where additional guidance would be most useful, either due to a lack of other guidance or an increase in incidents related to ageing asset issues. These are: Uninterruptable power supplies and Battery systems; Electrical drives; Electrical protection devices; Power cables; Switchgear (HV and LV); and Transformers. EEMUA 227 also provides general guidance on managing ageing electrical assets.

EEMUA Publication 179 Digital image

1996, Edition 1

ISBN: 978 0 85931 085 X

EEMUA Publication 179 A working guide for carbon steel equipment in wet H2S service

Version: Digital/PDF

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

Developed largely from oil refinery experience, this publication is aimed at providing guidance on minimising the damaging effects of wet H2S (hydrogen sulphide) on process plant, taking account of operating conditions, risk assessment, materials selection, fabrication, inspection (both of new and in-service equipment) and repairs. It comprises recommendations based on practical user experience of working with equipment in wet H2S service, together with relevant from reputable sources. This guide is applicable to any process plant handling wet H2S, and should be used in conjunction with User Standards to derive a policy for addressing problems or potential problems in new and existing equipment.

EEMUA Publication 180 Frangible roof joints for fixed roof storage tanks: Guide for designers and users

Version: Digital/PDF

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

Under abnormal operating conditions, vertical fixed roof storage tanks may experience rapid increases in vapour pressure which overwhelm venting devices and lead to tank failure. EEMUA 180 gives guidance to designers and users of such tanks on the practical steps that can be taken in design, operation and maintenance to predispose the roof-to-shell joint to fail in preference to the shell-to-bottom joint, thereby ensuring retention of the tank's contents. Such relatively weak roof-to-shell joints are known as 'frangible roof joints'. Guidance is also provided on how to determine the actual frangibility of tanks built before 1985 (the date where frangibility became known as a design requirement).

EEMUA also offers introductory e-learning in the area of Storage Tanks in both Dutch and English language versions.

2004, Edition 2 with corrigenda

ISBN: 978 0 85931 125 0

EEMUA Publication 182 Specification for integral block and bleed valve manifolds for direct connection to pipework 

Version: Digital/PDF

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

This specification covers integral block and bleed valve manifolds for direct connection to pipework, used as a replacement for individual block and bleed valves at tapping points in piping systems and also in larger arrangements for equipment and main process isolation. The aim of the specification is to ensure that such installations are fit for purpose and of the required integrity
