Ensco plc has taken delivery of ENSCO 121, the second of four ultra-premium harsh environment jackup rigs in its ENSCO 120 Series. The rig is contracted to work in the North Sea beginning in Q2 2014 at a day rate of approximately $230,000.
"The ENSCO 120 Series is ideal for ultra-deep well programs in challenging shelf environments," said, Chairman, President and CEO Dan Rabun.
ENSCO 121 was constructed at the Keppel FELS yard in Singapore and soon will be en route to Rotterdam for final load out and crew familiarization.
