Die kleintjes zijn zeker ook de moeite waard en doen ook hun werk. Er is ook al vaker aandacht aan besteed, in elk geval d.m.v. foto's.

Vroegaah in de Beaufort Sea nogal eens wat ijsblokjes gemaakt en ik heb "ergens" een mooie foto waar je daat "waterstraal" gebeuren goed kan zien, kan nu net niet vinden :oops:
Ijsbreken blijft " een apart vak" of je het nu met een dikke breker of met een klein scheepie doet, je moet het koppie d'r goed bijhouden anders maak je gauw schade...

Harry, Louis,

Bedankt voor de info.
In mijn leven slechts 1 maal een ijsbreker gezien. Dat was in februari toen het ijs in het Kanaal Alkmaar Kolhorn voor mijn deur werd gebroken. Met een gewoon slepertje.

Ik dacht dat de film bij Discovery was, in de serie Mighty Ships.Dus zal het wel een keer herhaald worden.
Deze Bulkfiets/ijsbreker haalde inderdaad nikkelijzer erts op. Het schijnt nog een linke lading te zijn want de ruimen werden vol gespoten met onbrandbaar gas om de zuurstof te verdrijven. Er mocht maar hoogstens 7% zuurstof in zitten.

mvg
Bob

Baltic Shipyard secures state contract for 60MW icebreaker of 22 220 Project.
JSC Baltiysky Zavod-Shipbuilding has been awarded state contract worth RUB 36.9 billion for the construction of the lead multipurpose icebreaker LK-60 with capacity of 60 MW of 22220 Project, the shipbuilding company said. The shipyard was the only contender for the order. On August 3 the tender was announced void and its only bidder was chosen to execute the contract. FSUE Atomflot invited bids for the icebreaker contract on July 3, 2012. Under the turn-key contract terms, Baltic Shipyard is to complete the order by December 30, 2017 and dock the newbuild at the berth of FSUE Atomflot in Murmansk. The keel-laying of the new icebreaker is scheduled for November 2013, launching ceremony for November 2015. In accordance with the approved schedule, bookmark the icebreaker on the stocks is scheduled for November 2013, launching - in November 2015. The scope of work included: development of technical documents, the construction (including the installation of nuclear power plant), outfitting, launching, on-dock testing, sea and icebreaking trials and the newbuild acceptance certificate signing by the state committee. The icebreaker LK-60 of 22 220 project will be the largest and most powerful icebreaker in the world, the report said. Ship’s main characteristics: length overall - 173.3 m, beam molded - 34 meters, draft at DWL - 10.5 m, minimum loaded draft - 8.55 m, displacement - 33.54 tons. The new generation double-reactor plant "RHYTHM 200" designed by Rosatom’s "OKBM" has reactors of thermal capacity of 170 MW each - more than that of the plants used in modern nuclear icebreakers (140-150 MW). The vessel features advanced double-draft capability, which makes it suitable for operations both in the Arctic waters, and in the mouths of the northern rivers. The icebreaker will be operating in the western region of the Arctic, the Barents, Pechora and Kara Seas and in shallow waters of the mouth of the Yenisei and the Ob Bay. Source : PortNews

Helsinki Shipyard to deliver Arctic OSV ahead of schedule
Finland's Arctech Helsinki Shipyard reports that it will complete the Arctic offshore supply vessel Vitus Bering four months ahead of schedule. The vessel is now set for delivery December 18. Initially, it was to be delivered in April 2013. Arctech Helsinki Shipyard is a 50/50 joint venture between STX Finland and Russia's United Shipbuilding Corporation. It is building two identical offshore icebreaking supply vessels for Russia's largest shipping group Sovcomflot (SCF Group), a world leader in ice-management and shipping in harsh environments.
The vessels will supply Exxon Neftegas Limited's platform in Arkutun-Dagi oil and gas field in Sakhalin area, Far East Russia. The development of the field is proceeding at good pace, which is why the icebreaking offshore supply vessels are needed in the area. The main task of the Arctic offshore vessels is to supply the oil and gas production platform and to protect it from the ice. Both vessels measure 99.9 m in length and 21.7 m in breadth. Their four engines have a total power of 18,000 kW and a propulsion power of 13,000 kW. The two vessels have been designed for extreme environmental conditions, they will be operating in thick drifting ice in temperatures as cold as minus 35 C°. Their icebreaking capability is extremely high, they are able to operate independently in 1.7 meter thick ice. As multipurpose vessels, they are capable of carrying various type of cargo and are equipped for oil spill response, fire fighting, and rescue operations. "The building of Vitus Bering has proceeded well, and we are now able to finalize it four months in advance," says the Project Manager for the newbuildings, Jonas Packalén of Arctech Helsinki Shipyard. He adds that the building of the sister vessel is proceeding well and its launching is planned for November-December 2012.
"Vitus Bering and her sister vessel are great examples of Finnish shipbuilding," says Esko Mustamäki, Managing Director of Arctech Helsinki Shipyard. "Modern design and long-term shipbuilding experience are combined in these projects. The finalizing of the vessels four months in advance has required excellent cooperation and team spirit. I'm sure that Vitus Bering and her sister vessel are a good start for prospective projects with participation of Russian United Shipbuilding Corporation and Sovcomflot for future work in the Russian Arctic. "The building of these two multifunctional icebreaking offshore vessels is the first order for Arctech, the joint venture owned by United Shipbuilding Corporation and STX Finland," says Andrey Djachkov, the President of United Shipbuilding Corporation. "This kind of cooperation between Russia and Finland is totally new, and I am happy to see that these new generation vessels with strong ice class are being built together with Russian and Finnish specialists. The vessels will be registered in Russia, they will work under the Russian flag and the crew will be Russian. Russia has a long experience working with Finnish shipbuilders. I think that collaboration in building these high technology vessels will undoubtedly assist further development of the Russian-Finnish shipbuilding cluster." Source : MarineLog

First Chinese ship makes trip to Atlantic via Arctic
The first Chinese ship has travelled from the Pacific to Atlantic via the Arctic along the Russian coast, an Icelandic scientist who participated on the expedition said Friday. The Chinese icebreaker Xuelong, or Snow Dragon, docked in Iceland after having sailed the so-called Northern Sea Route from the Pacific, Egill Thor Nielsson told AFP. "This is the first Chinese ship to sail this route and of course it is important because it's a more than 40 percent shorter route to Europe," he said. The Chinese are even more interested in this route after having found the passage relatively easy. "It took almost ten days to sail from the East Siberian Sea and through the Barents Sea, and during that time there was real pack ice for only seven days," he said. Climate change is opening the prospect of commercial shipping via the Northern Sea Route or the Northwest Passage north of Canada. More and more ships are travelling via the Northern Sea Route. Four made the passage in 2010, 34 last year and the figure will be higher this year, said Nielsson.
The Snow Dragon, bought from Ukraine in 1993, is currently China's only ice breaker. A second being built in China with the help of a Finnish company, should be completed in 2014. Source : ANP/AFP

3 icebreakers operate on the Northern Sea Route
There are currently three nuclear icebreakers assisting merchant shipping on the Northern Sea Route – the Russia, the Yamal" and the 50 Years of Victory. The last vessel has just recently completed a series of cruises to the North Pole, Atomflot said.
Another Atomflot’s vessel, the icebreaker Vaigach has completed its work on lines and has returned to the home port for routine maintenance and to prepare for winter navigation. The icebreaker Russia will soon head for Murmansk Malaysia, but in early September, will go back to the Arctic for the annual research expedition of the Arctic and Antarctic Research Institute to remove a manned drifting ice station NP-39 (North Pole-39) and to set up another one (NP-40). The icebreaker will depart the home port on September 8. Source : PortNews

Shipping developers eye up route through melting Arctic
While the rate of ice loss in the Arctic has alarmed environmentalists this summer, it has left maritime developers rubbing their hands with glee, as the prospect of a commercially viable Northern Sea Route looks increasingly likely.
Arctic Ocean here we come! China became the latest country to navigate the Northern Sea Route last week when its vessel Snow Dragon arrived in Iceland. Linking the Pacific Ocean to the Atlantic, the Northern Sea Route allows ships to cut down on travel time from Asia to Europe by edging through the icy waters between north Russia and the North Pole. China’s adventure shows its growing interest in the route. But they’re not the only ones whose appetites have been whet by the thawing of the Arctic: many in the Northern Hemisphere would welcome a commercial course that could rival the current route. Until now, ships have been forced to pass by Indonesia, India, the Gulf and finally through the crowded Suez Canal – which saw almost 18,000 vessels chug through last year alone – before reaching the Mediterranean.
Following a northern course instead – west above Canada or east above Russia – cuts the journey time by half, as pointed out by Chairman of Norway-based Tschudi Shipping, Felix H. Tschudi, in an interview with Japanese daily Asahi Shimbun published on Tuesday: "If a cargo ship with a maximum load capacity of 40,000 tons can pass through the Northern Sea Route, that will shorten the journey by 22 days and cost $839,000 [670,000 euros] less than going through the Suez Canal." The article also notes that 1,000 tonnes less fuel is needed for the northern journey. Also known as the Northeast Passage, the Northern Sea Route has only recently become accessible to large vessels due to the melting of the Arctic. Germany was the first Western power to make the journey in 2009, and was soon followed by Japan, Denmark, Canada and the UK.
In 2011, a total of 37 vessels made the trip. But this year saw record levels of thaw, allowing China’s icebreaker an easy passage, with the crew reporting an “astonishing” lack of ice as they skirted the North Pole.
“The Polar ice cap is currently smaller than it’s ever been,” explains Valérie Masson-Delmotte, a palaeoclimatologist and global warming specialist from the Climate and Environment Sciences Laboratory outside Paris. The US-based National Snow and Ice Data Centre registered record levels of ice loss in mid-August, when the Arctic mass shrivelled to 5.09 million square kilometres, or half of the 1979 to 2000 average for the same date. Today, it barely meets the size of the European Union.
And it’s not over yet. Masson-Delmotte says that the ice usually stops melting at the end of September, meaning the Arctic mass will get smaller yet before it begins to grow again in autumn. That’s good news for shipping giants, who benefit from the Northern Sea Route’s ever-longer summer accessibility. Today it’s navigable for around two months; a decade ago the passage was open for just a few weeks at the height of summer. Nonetheless, the Northern Sea Route and the Northwest Passage are far from becoming rivals to the Suez Canal, says Masson-Delmotte. “There’s certainly a new channel opening up,” she admits. “But it will be a few decades yet before we get to a point [when they’re busy commercial shipping routes].”
Wildly varying year-on-year conditions in the Arctic Ocean are far from an attractive prospect for shipping companies who need to schedule crossings during a short-lived period and in a region which is frozen over for the best part of the year. While 2012 was exceptionally mild, 2013 could make the Northern Sea Route a far less hospitable passage for seafarers.
That’s not to mention the infrastructure needed to accommodate an increased flow of traffic. There are currently very few ports along the route, which would pose as a problem in the case of an accident, and subsequently make the cost of insurance substantial. Each commercial vessel would be obligated to travel with a naval escort, costing around 400,000 dollars per crossing, says Liu Miaojia, a navigation expert at Bimco. But the true cost of the venture could be the environment. European environmental group Bellona describes the Arctic as "a more sensitive environment than regular places,” which would be better left alone. “We should abstain from developing the Arctic,” project coordinator Igor Kudrik told Asahi Shimbun. Environmentalists also argue that pollution from the vessels will accelerate the melting of the Polar ice cap, pushing sea levels even higher even faster. They also warn that an oil spill in the region would be far more complex to manage due to the special formation of ice masses. Source : France 24
