* Polar short-cut applications up to 15 for 2011, 4 in 2010
* Climate change opens Arctic to oil firms, miners, shipping

TROMSOE, Norway, Jan 25 Russia predicted on Tuesday a surge in voyages on an Arctic short-cut sea route in 2011 as a thaw linked to climate change opens the region even more to shipping and oil and mining companies.
High metals and oil prices, linked to rising demand from China and other emerging economies, is helping to spur interest in the Arctic and the route between the Atlantic and Pacific Oceans as an alternative to travelling via the Suez canal.
"In 2011 the shipping on the Northern Sea Route is going to increase significantly," Mikhail Belkin, assistant director of Russia's state-owned Rosatomflot, told a conference on "Arctic Frontiers" in Tromsoe, north Norway.
He said that Rosatomflot, which sends one of its nine atomic-powered ice-breakers to accompany each trip in case of ice, has received 15 applications to accompany voyages across the Arctic in 2011, against four trips in 2010.
"The potential savings are too large to be ignored," said Felix Tschudi, whose shipping group chartered the MV Nordic Barents in 2010 to carry 40,000 tonnes of iron ore for Northern Iron Ltd (NFE.AX) from Norway to China.
Tschudi said that the voyage was about 6,500 nautical miles (12,040 kilometres), about half the distance of the journey via Suez and saved 17-1/2 days as well as fuel. Icebergs meant high insurance costs but there are no pirates, unlike off Somalia.
He said Rosatomflot charged about $200,000 to accompany the ship, more than fees on the Suez canal. It was the first commercial vessel on the route that was not owned by Russia and travelled to and from non-Russian ports.
Arctic sea ice shrank in summer 2010 to the third smallest since satellite records began, after lows in 2007 and 2008. The U.N. panel of climate scientists says that greenhouse gas emissions are very likely the main cause.
Belkin said that other voyages in 2010 were to accompany an out-of-service passenger ferry, a tanker and a Swedish ice-breaker. In 2011, several oil or gas tankers were applying for the route.
Indigenous peoples expressed worries about oil exploration and mining in a remote region, where it could be far harder to stem any oil leaks, for instance, than in the Gulf of Mexico after BP Plc's (BP.L) catastrophic spill in 2010.
"The pace of development must meet our needs and not the needs of those who come to invest and those who come to take," said Aqqaluk Lynge of Greenland, head of the Inuit Circumpolar Conference which says it represents 150,000 Inuit.
He said investments such as oil and gas or aluminium could threaten hunting and fishing livelihoods and leave no lasting benefits for indigenous peoples.
But oil firms say they will take care of the environment.
"The world needs energy. We think that to supply that demand we have to go into the Arctic regions," said Steiner Vaage, head of ConocoPhillips (COP.N) Norway.
Norway, Finland, Russia and Sweden have all stepped up iron ore mining around the Barents Sea, said Morten Smelror, head of the Geological Survey of Norway.
"The main driving forces of these new investments are high prices of materials," he said, projecting that strong growth in emerging economies would keep up demand in coming years.
He said that promising, unexploited deposits around the Arctic included diamonds in Canada and rare earths in Greenland. For Reuters latest environment blogs, click on: blogs.reuters.com/environment/ (Editing by Louise Ireland)
