Secretary of the Interior, Ken Salaza, launches review of the 2012 offshore drilling program in the Beaufort & Chukchi Seas. The expedited, high-level assessment of the 2012 offshore drilling program in the Beaufort and Chukchi Seas is to review practices and identify challenges as well as lessons learned. The review, which is expected to be completed within 60 days, will pay special attention to challenges that Shell encountered in connection with certification of its containment vessel, the Arctic Challenger; the deployment of its containment dome; and operational issues associated with its two drilling rigs, the Noble Discoverer and the Kulluk.
