Floating Ice Platforms for Oil Exploration in the Arctic Islands
Exploratory drilling for oil and gas in the Arctic Islands has been in progress since 1961. A majority of the reserves are thought to lie offshore. To drill the offshore structures a method has been developed by which the natural ocean ice is artificially thickened into ice platforms which carry the...
