Royal Dutch Shell Plc’s pause in Arctic oil drilling after last year’s equipment mishaps should prompt a U.S. review of drilling procedures or a total ban, environmental groups said.

Two ships Shell was using in the Beaufort and Chukchi seas will be towed to Asia for repairs, the company said yesterday in a statement. In 2012, the company never got a U.S. permit to tap an oil reservoir off Alaska’s north coast because of issues with a spill containment system. It also encountered weather delays and was cited for violating air-pollution permits.
