Assemblin awarded additional installation assignment in the ESS research facility

Report this content

Assemblin’s ongoing installation assignment at the European research facility ESS in Lund, Sweden, has been expanded with additional electrical assignments, in this case procured directly by ESS. The new two-year assignment is worth approximately SEK 200 million.

In conjunction with the construction of the new research facility ESS (European Spallation Source) in Northeast Lund, Sweden, Assemblin has had overall responsibility for the installations of electrical, fire alarm and ventilation systems since 2015. The construction of the facility is divided in stages, and most recently at the end of last year Assemblin received an additional assignment by Skanska regarding installation of advanced electrical equipment in the first part of the 537-meter-long accelerator tunnel. It has now been confirmed that Assemblin has also been entrusted to carry out the electrical work in the remainder of the tunnel. The client is European Spallation Source ERIC. ESS will deliver world-class science from 2023, enabling scientific breakthroughs in a wide range of areas, such as environment, health, materials and energy. 

“We are naturally pleased and proud to be entrusted once again. ESS is one of the world’s most advanced research facilities, which imposes strict requirements on us as a supplier. Competence and experience are crucial in this kind of project, and we would not have received this assignment if ESS had not been satisfied with our prior work,” says Niclas Micha, Business Development Manager at Assemblin El.

The assignment will employ approximately 50 installers for two years.  The new contract covers installation of advanced electrical equipment in the facility’s accelerator tunnel. The assignment includes running cables (all types), wiring and connecting terminals, grounding equipment and related work. Work will involve all voltage levels in the facility.

“In all, we will be running approximately 715,000 metres of cable, which requires some 16,000 cables and 25,000 terminals. The installations are in a sensitive industrial environment that imposes specific requirements on the choice of cables and terminals. This is a challenge we take extremely seriously. This is a prestigious assignment that cements our position as the market leader in electrical technology,” says Fredrik Allthin, CEO of Assemblin El.
