Significant C25 Subsea Production System contract for the Norwegian North Sea

C25 will insulate numerous subsea structures, with work to be executed with support from expert team in Brazil.


In July this year, AIS was awarded a significant Subsea Production System contract for the insulation of 47-off Christmas Trees as part of a development in the Norwegian North Sea.

This was quickly followed in September by an award for the insulation of eight off-flow control modules. In addition to this, up to 35 structures are also expected in FY2023. Despite the field location, the work will be executed in Curitiba, Brazil, using ContraTherm® C25 and supported by our local team. The success of this contract is due to several key factors:

  • A strong commercial relationship with the customer, both locally in Brazil and globally.
  • Significant support in insulation design from our CAD/engineering team.
  • The excellent performance of the Brazil operations team in Curitiba.

Vicky James, Head of Subsea Sales had this to say:

“AIS is delighted to receive this important award, built on a long-standing relationship with the customer and our extensive track record in delivering for them to the highest quality. Strong teamwork, amongst different functions at AIS, has underpinned our success in this project. This allowed us to contribute to the customers design from the get-go so we can offer a truly engineered solution.”

This contract continues to solidify our relationship with this important customer. Work will be completed throughout several campaigns and will run from Feb 2024 to early 2026.
