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 183 Digital image

2011, Edition 2

ISBN: 978 0 85931 183 0

EEMUA Publication 183 Prevention of tank bottom leakage - a guide for the design and repair of foundations and bottoms of vertical, cylindrical, steel storage tanks

Version: Digital/PDF

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

Leakage from storage tanks may lead to extensive environmental pollution and be a financial loss to owners. This guide addresses the problem of tank leakage caused by loss of integrity. Such loss is almost always caused by deterioration of the tank bottom, which itself may be caused by corrosion or by deterioration of the foundation. This second edition is a comprehensive update that takes account of changes in standards, regulations and improvements in technology. EEMUA 183 gives guidance on a range of topics affecting tank bottom integrity including: design considerations for various types of tank foundations and bottoms; causes of tank bottom leakage; inspection records and techniques; corrosion protection; leak detection systems; and membranes as soil barriers.

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

EEMUA Publication 184 - Guide to the isolation of pressure relieving devices

Version: Digital/PDF

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

In order to permit their removal and replacement without plant shutdown, pressure relieving devices may need to be isolated from the equipment they protect. However, the installation of isolating valves around protective devices is potentially hazardous as it introduces the risk of a system being left unprotected against over-pressure due to the relief path being inadvertently closed off. Existing standards offer little or no detailed guidance in this area.

EEMUA 184 plugs the gap by expanding on the guidance given in API RP 520 Part II and incorporating EEMUA Information Sheet 50 - The Importance of isolation management around relief systems. It outlines the case for using relief valves as a layer of protection, gives advice on managing safe isolation and stresses the importance of safe de-isolation after completion of relief system work. EEMUA 184 provides several examples in loss prevention history where the failure to adequately manage relief system isolations has been a major factor in causing process safety incidents.

It is essential to conform to local statutory legislation or regulations in relation to the use, and isolation of, relief devices. In some countries, conformance to certain standards and codes may be a mandatory requirement and specific standards, such as those pertaining to boilers, may specifically prohibit the installation of isolation devices.

EEMUA Publication 185 Guide for hot tapping on piping and other equipment         

Version: Digital/PDF

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

Hot tapping, the term used when a branch is connected to a live or 'hot' piping system, is potentially hazardous particularly where flammable or toxic fluids are present. This publication offers guidance on how to carry out a safe and successful operation when hot tapping into metallic piping systems containing process fluids or their residues. It covers overall planning of the operation and includes hazard assessment and control, the constraints imposed by the nature, temperature and pressure of the process fluids, welding, testing and cutting (drilling/trepanning).

EEMUA Publication 187 Analyser systems - a guide to maintenance management 

Version: Digital/PDF

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

Analysers are used in industry to measure variables which significantly contribute to safety, environmental performance, asset protection and profit maximisation. The second edition of EEMUA Publication 187 covers performance target setting, strategies to improve reliability, methods to measure effective performance, and the organisations, resources and systems that need to be in place to allow this to occur. The new edition includes updated chapters on classifying analysers using a risk based approach, maintenance strategies, analyser performance monitoring, and a comprehensive glossary of terms.

EEMUA also offers introductory e-learning in the areas of Alarm Systems, Cyber Security and Functional Safety.
