Transocean announces plan to scrap another two floaters

Transocean Ltd. (“Transocean”) has announced that it intends to scrap, in an environmentally responsible manner, the following two rigs: GSF Aleutian Key and Sedco 707. These rigs were classified as held for sale and Transocean has decided to scrap them following failed attempts to find a buyer. As a result of this decision, the company expects its first quarter 2015 results to include an estimated non-cash charge of USD90 million to USD110 million, net of taxes. Including these two rigs, Transocean has announced plans to scrap a total of 18 floaters since the end of 2014. As the company continues to evaluate the long-term competitiveness of its fleet, additional rigs may be identified as candidates for scrapping. So far in 2015,a total of 11 drilling rigs (nine semisubs and two drillships) have been retired from the operational fleet and this number is projected to grow in order to rebalance supply within the market.
