About Sandnessjøen Lighthouse

Also known as: Sandnessjøen (Helgelandsbase)

A 5-meter concrete cylindrical post, painted white with a red lantern roof, was first lit in 1912 to guide ships to Helgelandsbase, an oilfield supply depot. This structure replaced an earlier light situated on a nearby rock. Its light flashes white, red, and green, cycling every 6 seconds, with a geographic range of 8.9 nautical miles. The lighthouse is located on an artificial island near Alstahaug in the Nordland region of Norway, within the Norwegian Sea. It is situated 0.2 km from the nearest port, Sandnessjoen.

Why it matters: This lighthouse is indispensable for the safe navigation of supply vessels heading to Helgelandsbase, a critical hub supporting Norway's offshore oil and gas industry in the Norwegian Sea.
