Securing the seabed and critical infrastructures is of paramount importance for Norway and other Scandinavian countries. Norway has an extensive coastline and a large maritime area, which includes rich fishing grounds, oil and gas resources, and important shipping routes. Securing these areas is crucial for the country's economy and national security.

Critical infrastructure such as oil rigs, pipelines, and communication cables are also important assets that must be secured. These structures are vulnerable to terrorist attacks, cyber-attacks, and natural disasters such as storms and earthquakes.
