Linde Kryotechnik delivers largest single component to ESS.

On 18 August 2017, Linde Kryotechnik delivered the core component of the refrigeration system for the European Spallation Source (ESS) accelerator. This was one of the biggest transport undertakings yet for the massive ESS project, with an oversize consignment measuring 39 m in length and 4.6 m in width arriving at the ESS grounds.

Moving the coldbox at all was a challenge – it is 14 m long and 4.7 m high with a diameter of 3.5 m and weight of 50 tonnes. Time and again, it pushed the boundaries of feasibility and called for new solutions – whether it be to assemble the inner workings with the outer shell or ready the box for shipping.

For transport by road, obstacles like roundabouts and signage had to be dismantled by an advance team and put back again once the vehicle had passed. Transport by sea was not possible from ports near Lund as they were not equipped to handle cargo with such huge dimensions. Ultimately, the cargo had to travel from Basel via Gent to Gothenburg for shipping. This resulted in a final onshore stage, where the transporter had to navigate an underpass with a guideline clearance of as little as 3 cm.

After 15 days en route, the cargo reached its destination at the ESS site in Lund, Sweden. It took one whole day to manoeuvre the delivery into the unloading hall.
The plant will be installed here in the next few months and the completed system is set to be handed over to ESS in autumn 2018.

The second order from ESS, the TMCP (Target Moderator Cryo Plant), is under construction.
