The corona virus (officially COVID-19) is spreading. No reason to panic, but it is important to take a number of measures to prevent the virus from spreading as much as possible. The National Institute for Public Health and the Environment (RIVM) monitors the spread of the virus and indicates which measures (should) be taken. Based on those measures and the current situation, Sif has daily crisis team consultations. This resulted in the following guidelines. Because we operate on a daily basis, the guidelines below can be adjusted daily:

Despite the concerns and measures due to the corona crisis, our craftsmen and women are still working hard to fullfill our orderbook in a responsible and safe way. Thanks to their dedication, inventiveness and resilience, we have reached a special milestone: Sif’s 2000th monopile!

Residents of the Netherlands are discouraged from visiting private occasions where groups of people are present. We follow this policy for all Sif employees. We take the following measures regarding work situations:

  • Only visits (at Sif or elsewhere) that are necessary for safety reasons or to keep production going (for example maintenance and repair) are allowed. Other visits or activities are suspended until further notice.
  • If business group meetings are planned, such as company visits, guided tours or presentations, they must be postponed until further notice or be offered in another way (online).
  • Physical meetings with more than 6 people are not allowed.


In general and for everyone: Try to communicate as much as possible via telephone, e-mail and Skype.
