With over 150 years’ in-depth experience in the UK and international markets, Altrad Motherwell Bridge is a world leader in designing and constructing storage tanks and gasholders. Our highly-skilled and experienced employees work closely with our customers to understand their specific project requirements to develop safe, cost-effective and industry-leading solutions.
Oil and liquids storage
Altrad Motherwell Bridge is one of the very few storage tank contractors to retain an in-house storage tank design team, with all its attendant benefits.
Our storage tanks are manufactured and delivered on-site for construction by our highly skilled personnel, many of whom have been with the company for more than 25 years.
Many larger engineering companies would need to sub-contract storage tank construction resulting in significantly increased costs for you. By contracting directly with Altrad Motherwell Bridge, you save money and, with our unparalleled experience, can be rest assured we will construct on time and on budget.

Altrad Motherwell Bridge’s Clayton Walker Gasholder division is one of a small group of companies across the globe with the capability of providing solutions for low-pressure gas storage.
As gas storage requirements are different from one process to the next, from site to site and region to region, each gasholder project is addressed with the highest regard to detail, ensuring the final, bespoke design solution completely satisfies customer and local requirements.
Our construction services typically include on-site technical support, covering all variations of shop, site, testing and commissioning activities. In providing these services we are able to provide experience-based advice and assistance to our customers with respect to construction methodology, build and welding techniques, manning levels, scheduling, inspection, testing and quality control.
Where capital has not been available to fund a new build and conversion is a feasible long-term alternative, complete solutions can be provided to fully transform gasholders of poor performing and out-dated technology to the superior Wiggins type concept. We have also carried out partial conversions where “best-available-technology” or know how with a long-proven track record on other gasholder designs is retro-fitted to enhance the gasholder’s performance.
Through our continuous development programme we can assure our customers receive industry-leading gasholder products and services encompassing the current best-available technologies at the time.
Clayton Walker Gasholder’s expertise covers:
- Water-sealed, Oil-sealed (MAN type) and Dry-sealed (Wiggins type) gasholders
- Gasholder conversions
- Retro-fits to gasholders
- Gasholder maintenance, repairs and overhauls
- Bespoke and statutory inspection services
- Troubleshooting and failure investigations
- Gasholder design verification
- Structural design
- Piping design
- Gasholder instrumentation
- Technology development and improvement
- Hazardous area classification and operation/identification
- ATEX assessment of gasholders.
Design and construction
At Altrad Motherwell Bridge, we offer a full range of gasholder inspection and maintenance services to our customers. Our employees are equally comfortable providing assistance to customers with routine on-line and statutory inspections, or the undertaking of a complete off-line, internal inspection to an agreed workscope.
Where storage tank or gasholder operation is problematic or undesirable, we work closely with our customer to establish an effective and sustainable solution through the provision of trouble-shooting and root-cause analysis services.
In all instances, our highly skilled and experienced workforce will work closely with our customers to develop the right work programme to enable the completion of all storage tank and gasholder projects accurately and efficiently, keeping costly shutdown time to a minimum.

Altrad provides leading innovative industrial cleaning and decontamination services for tanks to some of the world’s largest multi-national oil and gas companies.
The key to our success lies in having the most advanced technology and a team of highly-qualified and dedicated people with the right skills, training and a commitment to deliver for our customers. Our emphasis on safety and innovation, including Non-Man Entry Techniques, allows us to provide pioneering work techniques.
Removing product, by-product, scale or corrosion helps achieve maximised capacity, increased throughput, enhanced product quality and improved production levels, therefore offering greater cost effectiveness. We bring unrivaled experience and expertise in tank cleaning as our highly-skilled teams can deliver either manual or automated cleaning capabilities as appropriate for a customer’s specific project needs.
Manual process’ have incorporated the use of man-way cannons to circulate and fluidise tank sludge so that it can be pumped to the Altrad Membrane Filter Press to reduces the effluent volume to be taken offsite for disposal. The Altrad Membrane Filter Press separates oil from solids and has a solvent back wash system so that any residual oil content can be further reduced to meet non-hazardous landfill specifications, reducing costs for our customers.
For lighter hydrocarbon containing tanks like Kerosene or Diesel, we use spinning chemical or high-pressure water tank cleaning heads. After gas freeing the tank, we would then enter the tank for final steam clean and inspection to achieve traditional hot work standards.
Enclosed 2-D and 3-D non-man entry tank cleaning systems enable greater flows and operating pressures to be brought to bear on tank deposits, resulting in superior cleaning results and lower safety risk. These remote high-pressure water jetting cleaning systems enable our customers to quickly plan for more extensive cleaning, reducing plant downtime significantly.
