Arctic Corridors

Routes through the ice

Three primary Arctic maritime corridors, each demanding specialised expertise, distinct regulatory frameworks, and precise seasonal timing. We navigate all of them.

01
Year-Round

Northern Sea Route

Barents Sea — Bering Strait  |  14,000 km

The NSR runs along Russia's Arctic coastline from Novaya Zemlya in the west to the Bering Strait in the east. Summer transits (July–November) offer open-water passages; winter operations require nuclear icebreaker escort coordination with Rosatom FSUE Atomflot. This is our primary operational corridor, accounting for the majority of our guided transits.

Northwest Passage

Baffin Bay — Beaufort Sea  |  14,800 km

Running through the Canadian Arctic Archipelago, the NWP offers an alternative trans-Arctic route connecting the Atlantic and Pacific. The route has multiple variants through different straits; the southern route through Prince of Wales Strait is most navigable. Heavily regulated by Transport Canada and subject to AWPPA requirements. Ice conditions remain challenging and season length highly variable.

Transpolar Sea Route

Svalbard — Bering Strait  |  12,700 km

The TSR crosses the central Arctic Ocean — the shortest possible route between Atlantic and Pacific. Currently only navigable in high summer for ice-class vessels, this route is emerging as a viable option as sea ice extent reduces. No territorial waters are crossed, eliminating permit complexity, but distance from emergency support infrastructure demands exceptional voyage preparation and vessel capability assessment.

Arctic Ocean — seasonal ice extent
Winter
Heavy Ice
Icebreaker escort mandatory. Navigation limited to nuclear-class escort corridors. Extended polar night.
Spring
Fractured Ice
Ice beginning to break. Eastern sectors remain challenging. Leads forming in western approaches.
Summer
Open Water
Prime transit season. Low ice concentration. Most ice-class vessels can navigate independently.
Autumn
Refreezing
Ice forming in eastern sectors first. Transit window closing. Close ice monitoring essential.
