A slab of pykrete Pykrete is made of 14% sawdust and 86% water by mass.. Pykrete (/ ˈ p aɪ k r iː t /, PIE-creet) [1] is a frozen ice composite, [2] originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight).
Conceptual design of Project Habakkuk aircraft carrier with 600-metre (1,969 ft) runway. Project Habakkuk or Habbakuk (spelling varies) was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete, a mixture of wood pulp and ice, for use against German U-boats in the mid-Atlantic, which were beyond the flight range of land-based planes at that time.
The MythBusters demonstrated that pykrete is bulletproof by subjecting a wastebasket-sized chunk of ice and another of pykrete to a close range impact (approximately 10 ft or 3.0 m) by a .45 caliber round. The ice shattered upon impact, and the bullet easily penetrated it.
The Build Team then decided to scale up the sawdust experiment, using a larger, more powerful cannon and extremely flammable powdered non-dairy creamer. This created a massive fireball that greatly startled the Build Team and buried one of their ground-level cameras under a thick layer of burnt creamer.
Yamal can break ice while making way either forwards or backwards. Yamal is one of the Russian Arktika family of icebreakers, the most powerful icebreakers in the world. These ships must cruise in cold water to cool their reactors [failed verification], so they cannot pass through the tropics to undertake voyages in the Southern hemisphere. [3]
Umiak I is a purpose-built ice-strengthened bulk carrier constructed for the Voisey's Bay Nickel Company, [4] a wholly owned subsidiary of Vale, to transport ore from the Voisey's Bay Mine. According to an article in the April 2006 issue of The Gossan an internal publication of the Voisey's Bay Nickel Company, Umiak I had completed her sea ...
Almost none of Canada's Northern communities have any port facilities, a fact the series portrays dramatically as it shows the extra difficulties the ships face unloading cargo: (1) unloading and launching a tugboat and barge, they carry as deck cargo; (2) using the tug and barge to carry front end loaders to the community's beach, where they will then unload pallets of cargo from subsequent ...
RSV Nuyina is an icebreaking research and supply vessel intended to support Australian scientific activities and research bases in Antarctica. Capable of deploying a wide range of vehicles, including helicopters, landing barges and amphibious trucks to support the resupply operation, the new ship provides a modern platform for marine science research in both sea ice and open water with a large ...
