U.S. Sen. Mark Begich says he will conduct a hearing in Alaska to examine why a Royal Dutch Shell PLC drill rig ran aground on a remote island.
The Kulluk (CULL'-uck) drilled in the Beaufort (BOH'-fort) Sea off Alaska's north coast during the 2012 open water season. It was being towed to Seattle for maintenance and upgrades Dec. 27 when its tow line broke.
Reattached lines also broke, and the vessel ran aground New Year's Eve.
A Shell towing vessel pulled the barge off the rocky bottom Sunday night and towed it Monday to a sheltered Kodiak Island bay.
Begich, an Alaska Democrat, is chairman of the Senate Subcommittee on Oceans, Atmosphere, Fisheries and the Coast Guard.
