What is EEMUA 159? 

In a world of industrial safety and asset management, standards play a vital role in ensuring operational integrity and minimising risks. EEMUA 159 is a widely recognised standard relating to tank inspection in the UK. But what is EEMUA 159?

If you are involved in industries such as oil and gas, chemical processing, or power generation, understanding EEMUA tank inspection is essential. 

We hope to shed some light on EEMUA 159 tank inspection, by exploring what it is, why you should use it, and its benefits for industries like yours. 

What is EEMUA 159? 

EEMUA, which stands for Engineering Equipment and Materials Users Association, is an independent organisation established in the UK. 

EEMUA’s primary focus lies in providing guidance and developing technical specifications for the safe operation, maintenance, and management of industrial equipment and systems.

EEMUA 159 is a comprehensive document that has been created by EEMUA, entitled “Above Ground Flat Bottomed Storage Tanks: A Guide to Inspection, Maintenance, and Repair.” 

Its purpose is to provide industry best practices for ensuring the safe and reliable operation of above-ground storage tanks used in various sectors, including oil and gas, petrochemicals, and pharmaceuticals.

The standard addresses various aspects, including tank design, materials selection, fabrication, inspection, and maintenance. It also covers topics such as corrosion protection, tank foundations, roof structures, and bottom plates.

Originally introduced in 1987, EEMUA 159 has undergone updates over the years to reflect developments in technology and industry practices. It provides detailed recommendations for the design, construction, installation, inspection, and maintenance of storage tanks, emphasising safety, reliability, and environmental protection.

How is EEMUA 159 used?

Anyone signing off on a tank inspection should be qualified as an EEMUA 159 tank inspector. 

After a tank has been inspected by a non-destructive testing technician, an EEMUA 159 tank inspector should check the results of the test against the EEMUA 159 documentation. They will then produce a completed Written Scheme of Examination and a Fitness Purpose Report detailing the estimated remaining life of your assets. This will help you to put together a repair and maintenance programme for your assets. 

Who uses EEMUA 159? 

Here are two examples, among many, of industries that use EEMUA 159.

The oil and gas sector relies heavily on EEMUA 159. Oil companies use large above-ground storage tanks to store crude oil before it is transported to refineries for processing. The EEMUA 159 standard ensures the safe and reliable operation of these tanks by providing guidelines for regular inspection, maintenance, and repair. 

Additionally, chemical plants also use EEMUA 159 for their storage needs. Chemicals require specific handling and strict safety protocols due to their hazardous nature, and following this standard helps make sure that handling procedures are followed correctly.

Why use EEMUA 159? 

1. Reduce damage

Firstly, by following the recommendations outlined in EEMUA 159, you can reduce the risks associated with storage tank failures, which can lead to catastrophic incidents, environmental contamination, and financial losses.

2. Improve cost-effectiveness

Secondly, EEMUA 159 helps to promote good engineering practices and encourages the use of risk-based inspection strategies, helping you to optimise your tank maintenance programmes. This means you can reduce the amount of money you need to spend on repairs or allocate funds for maintenance more efficiently. 

3. Regulatory Compliance 

Also, you can meet regulatory requirements related to tank integrity and safety, by following industry-specific regulations and guidelines. 

EEMUA 159 represents the collective expertise and experience of professionals across various industries. By adopting this standard, you can benefit from industry best practices and stay ahead in your plans for asset management.

Key Sections of EEMUA 159

EEMUA 159 is divided into several sections, each focusing on specific aspects of tank inspection and management. Some of the essential sections and recommendations within the standard include:

1. Design and Construction 

The standard outlines design considerations, material selection, and construction methods to ensure tanks are built to withstand various operational and environmental conditions.

2. Inspection and Maintenance 

EEMUA 159 tank inspection emphasises regular inspection and maintenance routines, including visual checks, non-destructive testing, and monitoring techniques. It provides guidance on establishing inspection intervals and assessing the tank’s condition effectively.

3. Repairs and Alterations

The standard offers guidance on repairs and alterations, including criteria for repairs, methods for assessing defects, and considerations for material compatibility during modifications.
