Havsil

Overview

Havsil is a short submarine cable system spanning approximately 120 km across the Skagerrak strait, connecting Denmark and Norway. It serves the bilateral corridor between these two neighboring countries, providing a direct subsea link across the narrow stretch of sea that separates the Scandinavian Peninsula from the Jutland Peninsula.

Route and Landings

In Denmark, Havsil lands at Hanstholm, a coastal town on the northwestern tip of Jutland. In Norway, the cable comes ashore at Kristiansand, a city on the southern Norwegian coast. These two landing points sit directly across the Skagerrak from one another, consistent with the cable's compact 120 km length.

Ownership and Operators

Havsil is owned by Bulk Infrastructure, a Norwegian data infrastructure company with interests spanning data centers, fiber networks, and subsea cable systems across Northern Europe.

Technical Profile

No details on fiber pairs, capacity, or technology supplier are available for Havsil at this time.

Status and Timeline

Havsil entered service in 2022 and is currently operational.

Regional Context

The Denmark–Norway corridor hosts several submarine cable systems of varying scale. Havsil is among the shorter systems in the region, considerably more compact than the trans-Atlantic Havfrue/AEC-2, which also touches both Denmark and Norway and extends to 7,650 km. Longer Norwegian domestic and Arctic systems such as the Svalbard Undersea Cable System and Polar Circle Cable serve different geographic needs within Norway's coastal and offshore network. Upcoming systems including Arctic Way and N0r5ke Viking 2 are planned for 2028, while N0r5ke Viking entered service in the same year as Havsil. Within this landscape, Havsil occupies a distinct position as a short, direct bilateral link across the Skagerrak.

Measured over the last 60 days across 55 ping tests, Havsil records an average round-trip latency of 21.7 ms, with a best recorded result of 12.7 ms. These figures reflect the cable's short physical distance between landing points.

Strategic Role

By linking Hanstholm in Denmark directly with Kristiansand in Norway, Havsil provides a dedicated subsea path between the two countries under the Skagerrak. Owned and operated by a single infrastructure provider, it represents a privately held bilateral connection in a corridor otherwise served by systems involving multiple stakeholders or spanning far greater distances.
