Melting Arctic ice clears the way for supertanker voyages

What could possibly go wrong? John Vidal in the Guardian (UK): Supertankers and giant cargo ships could next year voyage regularly between the Atlantic and Pacific Oceans via the Arctic to save time, money and emissions, say Scandinavian shipowners.

New data from companies who have taken advantage of receding Arctic sea ice this year to complete several voyages across the north of Russia shows that the "northern sea route" can save even a medium size bulk carrier 18 days and 580 tons of bunker fuel on a journey between northern Norway and China.

Even bigger fuel and time savings have been reported this week by Danish shipping company Nordic Bulk Carriers which says it saved a third of its usual costs and nearly half the time in shipping goods to China via the Arctic.

The route, which cuts around 4,000 nautical miles off the southern Suez route from the Atlantic to the Pacific, has barely needed an ice-breaker since July as annual sea ice melted to a near record low extent. "We saved 1,000 tonnes of bunker fuel – nearly 3,000 tonnes of CO2 – on one journey between Murmansk and north China," said Christian Bonfils, a director of Nordic Bulk Carriers in Oslo.

The shipowners, who anticipate that the northern route could gradually be opened for four to six months a year as air and sea temperatures increase, are exploring the possibility of regular summer passages through the Arctic ocean. This could save them €180,000-300,000 on each voyage, they say....
