Houstrup, Denmark: Submarine Cable Landing Point

Houstrup is a submarine cable landing point located on the coast of Denmark, a country with an established submarine cable infrastructure spanning 34 landing points and 30 cables. Two submarine cables land at Houstrup, connecting Denmark to a range of North Sea and European partners. The landing point sits within a broader Danish network that has been developing since 1989 and encompasses a diverse set of regional and intercontinental corridors.

The two cables serving Houstrup establish connections across the North Sea, linking Denmark primarily to the United Kingdom, as well as to Germany, the Netherlands, and Norway. Together, they position Houstrup as a node within the North Sea regional submarine cable corridor, enabling data exchange between Scandinavia, the British Isles, and continental European coastal states.

Cables Landing at Houstrup

IOEMA is a 1,620-kilometre submarine cable with a projected ready-for-service (RFS) date of 2028, currently at draft stage. In addition to Denmark, the cable connects Germany, the Netherlands, Norway, and the United Kingdom, making it a multi-country North Sea system. Its geographic span across five countries represents one of the more extensive cable networks associated with the Houstrup landing point.

Havhingsten/North Sea Connect (NSC) is a 661-kilometre submarine cable with an RFS year of 2022, also listed at draft stage. The cable links Denmark to the United Kingdom, forming a direct bilateral connection across the North Sea. At 661 kilometres, it falls above the Danish national average cable length of 452 kilometres, reflecting the distance across the North Sea between the two countries.

Regional Context

Within Denmark's 34 landing points, Houstrup hosts 2 cables, placing it in the top 94% by cable count — a figure it shares with several peers including Brondby, Helsingør, Laeso, and Lyngsa. Landing points such as Blaabjerg, with 5 cables, and Gedser, with 4, serve as larger hubs within the Danish network. Houstrup occupies a mid-tier position in the national infrastructure landscape, consistent with a number of Denmark's coastal landing points that serve focused bilateral or regional connections rather than large multi-cable convergence points.

Network Role

Houstrup functions as a two-cable landing point within the North Sea submarine cable corridor. The Havhingsten/North Sea Connect cable provides a direct Denmark–United Kingdom link, while the IOEMA system broadens connectivity to Germany, the Netherlands, and Norway, extending Houstrup's reach across five North Sea countries. Together, the two cables give this landing point both a bilateral and a multi-lateral dimension within the regional submarine network.

As a two-cable terminus rather than a large convergence hub, Houstrup contributes a focused set of North Sea routes to Denmark's overall submarine cable graph. Its role within a national network that totals 30 cables across 34 landing points reflects the distributed character of Danish submarine cable infrastructure, where connectivity is spread across many coastal points rather than concentrated at a small number of dominant hubs.
