WASHINGTON — The U.S. Interior Department on Wednesday granted Royal Dutch Shell its final two permits to drill in the Arctic this summer but said the company cannot drill into the oil zone yet.
Shell must have emergency equipment called a capping stack deployable before drilling into the oil zone in the Chukchi Sea off Alaska, the government said. The company discovered weeks ago that an icebreaker it is leasing, called the Fennica, which holds the required capping stack, had a gash in it.
It sent the ship to Portland, Oregon, for repairs. Fixing the gash and the trip back to waters off northern Alaska could take weeks.
