ZUG, Switzerland, Dec. 27, 2012

ZUG, Switzerland, Dec. 27, 2012 /PRNewswire/ --Noble Corporation (NYSE: NE)
today announced that it is working cooperatively and diligently to rectify
deficiencies and maintenance issues raised by the U.S. Coast Guard during a
recent inspection of the Company's drillship, the Noble Discoverer. The
inspection followed a successful drilling season in offshore Alaska.

The Coast Guard has identified several components and systems aboard the
Company's drillship for attention, including the ship's propulsion and safety
management systems. In connection with Noble's internal review independent of
the Coast Guard inspection, Noble reported certain other potential regulatory
non-compliance issues that it discovered relating to its operations, including
possible unauthorized collected water discharges outside the period of
drilling operations.

Noble has already resolved a number of the issues with the Noble Discoverer
identified by the Coast Guard and plans to complete the remaining items during
the previously scheduled shipyard stay in Washington. The drillship is
currently being mobilized to the shipyard. Noble and Royal Dutch Shell (the
current customer for the Noble Discoverer), in coordination with the Coast
Guard, are also reviewing the drillship's operations in Alaska and the impact
of the 2012 arctic operating conditions with the intent of further
strengthening the readiness of the drillship and the other drilling assets for
2013. Additionally, the Company is developing an enhanced plan designed to
ensure its drilling rigs and their related management procedures are in
compliance with applicable maritime laws and leading industry practices.

Noble continues to cooperate with the Coast Guard's ongoing review, as well as
conducting its own investigation and a review of its marine management
processes and procedures. The Company cannot make any assurance as to the
timing, impact or outcome of the Coast Guard investigation or its own
investigation into these regulatory matters.
