Subsequent Events [Abstract]
Subsequent Event	Note 24- Subsequent Event In January 2015, we repurchased 6.2 million of our ordinary shares at an average price of $16.10 per share, excluding commissions and stamp tax. Including these items, the average price paid per share during January 2015 was $16.21. There can be no assurance as to the timing or amount of any additional repurchases. However, we intend to take a cautious approach to future share repurchases at least until market conditions in the offshore drilling business stabilize.
