The Royal Dutch Shell Plc (RDSA) has scrapped its plan for drilling to find oil in American state of Alaska this year mainly because the doom to cover a spill was damaged.

The company will need a lot of time to fix the dome that prevents oil from spilling into the region and affecting the natural life there. A lot of time is required to repair the dome while taking steps to protect local whaling operations and to ensure the safety of operations from ice floe movement. Thus it will be unable to drill the area looking for oil resources this year, according to a statement from the company.

The Hague-based company is planning to drill several top holes in order to facilitate drilling plans in the next year. Shell had started drilling in Alaska's Chukchi Sea after preparing for six year as it received a permit from the U. S. Interior Department.

"We are disappointed that the dome has not yet met our stringent acceptance standards, but as we have said all along, we will not conduct any operation until we are satisfied that we are fully prepared to do it safely," the company said.

The company has invested 4.5 billion on the offshore leases and equipment for its operations.
