The challenge

In 2016, the integrated site team carried out non-destructive testing inspection and identified significant corrosion under insulation on two of the fuel oil tanks. Our team undertook further inspections and prepared a detailed technical report which provided recommendations to address corrosion under insulation (CUI).

The solution

Uniper required an accelerated solution to support the availability of the power plant in advance of the winter demand, whilst also ensuring the integrity of the tank.

Altrad designed the most suitable protective coating selection and insulation system to prevent corrosion and extend the life of the tank.


  • A rapid solution allowed Uniper to fulfil the winter demand for electricity
  • The solution was provided in a cost-effective manner
  • The life of asset was extended
  • Corrosion under insulation was eliminated

Let’s start the conversation

Quite simply, a journey at Altrad begins with a desire to create a better tomorrow.
