Alfa Laval reports that its Aalborg, Denmark, site has adapted to restrictions imposed in response to the COVID-19 pandemic and is continuing production of PureBallast 3 ballast water treatment systems. The factory continues to meet global production demands – and has even surpassed expectations.

“While the world has slowed down, the implementation of the ballast water management convention remains unchanged,” says Peter Sahlén, Head of Alfa Laval PureBallast. “We simply must continue meeting our customers’ needs, regardless of the obstacles.”

Those obstacles have been large. The Aalborg facility normally bustles with manufacturing teams, customers, class society representatives and visitors. Now, Alfa Laval is securing customer deliveries, but with far fewer people on the factory floor.


Alfa Laval’s approach has been a combination of rapid response and innovative thinking.

The company took swift action both to implement protective measures for employees, but also to secure the components and materials that would be needed in the months ahead. When the Danish government imposed a strict lockdown on March 11, the Aalborg factory was well prepared.

“We moved quickly from two shifts to three shifts, working in smaller teams that can easily maintain a safe distance,” says Søren Nord Larsen, who manages the factory. “There’s no contact between shifts. So, if one of our workers should be infected, we can lift the entire shift out without impacting the others or any customer deliveries.”

Even meals and breaks are taken individually, at different times. Tools are carefully handled and disinfected regularly, and support functions like purchasing and production planning are managed digitally to the greatest extent possible.

“It’s tough to change so quickly and dramatically, but colleagues have really taken the situation with a positive attitude and adapted to the new routines,” says Larsen. “Many come with their own ideas for improving things, because everyone wants this to happen for our customers.”


The success of these efforts is underscored by the fact that Alfa Laval has managed to increase production during the period.

“We’ve proven that this can be done, and we’re not simply maintaining the status quo,” says Larsen. “In March we set a record of 400 systems produced for the quarter, and our deliveries for the quarter were yet another all-time high.”

For Peter Sahlén, the high productivity in Aalborg builds on Alfa Laval’s long-term planning.

“We’ve made extensive preparations for ramp-up in the last two years, and that readiness has served us well in this unusual situation,” he says. “We already had a systematic overview and allocated resources, which made it easier to recalibrate. Together with our customers we will make it through this situation – and our production will be even stronger on the other side.”
