Stronger momentum in Norway’s maritime cluster
Norway’s maritime sector is experiencing one of its strongest periods in decades, driven by national growth and the exceptional performance of the Møre og Romsdal cluster, home to Ulstein and many leading companies.

When voyaging is in the genes
For Norway, the relationship with the sea is so fundamental that it is reflected even in the country’s currency. For centuries, people have relied on the sea, not for conquest or adventure, but for survival, transport and connection. Long before the age of the Vikings, boats were already an essential part of everyday life, shaped by the need to operate safely and reliably in open, often unforgiving waters. Rock carvings and archaeological finds show that early vessels were carefully adapted to their environment, evolving over generations through experience rather than ambition.
