The Kulluk, a 266-foot diameter, 30-year-old circular drilling rig, had been mothballed in Canada for a dozen years before Shell bought it in 2005 for an untold sum and invested $292 million in upgrades and retrofitting. The 514-foot-long Noble Discoverer is even older, built in 1966 and converted into a drilling ship 10 years later.

In another costly setback for Royal Dutch Shell’s controversial Alaska Arctic endeavor, both drilling rigs used offshore during last year’s oil exploration season will be towed out of the water on massive vessels to Asia for further inspection and repair, Shell announced Monday.
The decision suggests the Kulluk and the Noble Discoverer — Shell’s only drilling rigs for the Arctic — need major work and calls into further question whether Shell will be able to resume drilling in the Chukchi and Beaufort seas this year. Two federal investigations are under way into Shell’s Alaska operations.
