ZUG, SWITZERLAND--(Marketwired - May 13, 2013) - Transocean Ltd. (NYSE: RIG)
(SIX: RIGN) today announced that J. Michael Talbert has advised the Board of
Directors that, if re-elected at the company's upcoming Annual General Meeting
("AGM") on May 17, he will retire from the Board no later than the company's
2014 AGM. To facilitate an orderly transition of leadership, should Mr.
Talbert be elected by the Board as Chairman following the upcoming AGM, he
will step down as Chairman no later than the Board's November 2013 meeting, at
which time a new, independent Chairman will be announced.Mr. Talbert,
formerly CEO of Transocean from 1994 to 2002, has served on the Board of
Directors since 1994.

Mr. Talbert said, "I am honored to have served Transocean, and to have done so
as a member of a very knowledgeable and experienced Board of Directors.During
my 20 years at Transocean, I have worked diligently to represent the best
interests of all of our stakeholders.In this spirit, and after consultations
with our shareholders, I have decided to retire from the Board on a timetable
that will allow the Board to carefully select a new chairman who will help
guide the company in the creation of sustainable, superior value for all
shareholders."

The Board of Directors issued the following statement:

On behalf of the Board, our shareholders, employees and other stakeholders, we
would like to thank Mike for his many years of service to the company,
including eight years as CEO and three terms as Chairman, and we look forward
to continuing to work with him until his retirement.In conjunction with the
Board and management, Mike had the vision to transform Transocean into the
world's leading offshore driller with the most capable fleet in the
industry.In addition, he helped shepherd the company through the
extraordinarily challenging period following the Macondo incident and was, and
continues to be, instrumental in guiding management in the creation and
implementation of key operational initiatives that are positively impacting
the company's performance.His contribution to the Board will be sorely
missed.

"Mike's deep industry and company knowledge, thorough understanding of the
value we provide our customers and consistent, strong leadership have played a
very important role in making Transocean the company it is today," said Steven
Newman, CEO of Transocean. "I want to personally thank him for his mentorship,
counsel and guidance, particularly during the difficult period following the
Macondo incident, and I look forward to continuing to benefit from his
leadership until his retirement."

The company's Corporate Governance Committee intends to promptly commence a
process to identify a candidate to fill the vacancy resulting from Mr.
Talbert's retirement from the Board.As it conducts this process, the
Committee will take into consideration the views of the company's
shareholders.This process will be consistent with Transocean's historical
focus on regularly infusing fresh perspectives into an experienced and
knowledgeable Board as evidenced by the fact that, if elected, current Board
nominee Frederico Curado will be the seventh independent Director to be added
to the Board during the past two years.Among other characteristics, the
Committee will seek a clearly independent candidate with the relevant skills,
character, diverse background and global experience to enhance the Board's
decision-making process and to further its objective of creating value for
shareholders.
