Royal Dutch Shell has submitted revised proposals to the US Government to try and explore for oil in the Alaskan Arctic.
It consists of two drilling rigs working simultaneously in the Chukchi Sea, which is expected to produce more than 400,000 barrels of oil per day.
The work, which has had opposition from environmentalists, was put on hold earlier this year after a series of incidents.
Shell emphasised it “has not made a final decision yet” on whether it will drill next summer but is “undertaking activities to preserve the option of a 2015 season”.
A spokesperson added: “We continue to take a methodical approach to this exploration phase and will only proceed with a programme that meets the conditions necessary to proceed safely and responsibly.”
