Oil major Royal Dutch Shell has decided to delay its hunt for oil in Alaska until next year after a piece of equipment used in a test was damaged, highlighting the difficulties of drilling in the icy Arctic sea.
Shell, which has spent about £2.7billion on its effort to drill Arctic oil, said it will not attempt to drill into any oil or gas-containing rocks this year as a dome which could be used to contain oil in the event of a spill will take time to repair.
