Eni terminatesOcean Rig Olympia contract
Eni has terminated its contract with Ocean Rig UDW Inc. for the ultra-deepwaterOcean Rig Olympia drillship. The rig provider said that the Italian company had reassessed its drilling activities and moved to terminate the contract “due to the dramatic fall of the crude oil price and the volatile market context.”
Ocean Rig announced in May 2015 thatOcean Rig Olympia had entered into a new contract with Eni to drill offshore Angola. Work was to begin in 3Q 2015 for a minimum of eight months with a total contract backlog of about $91 million.
The DP-3 classOcean Rig Olympia was built at Samsung Heavy Industries’ South Korean shipyard. The 2011-build is designed and equipped for drilling in water depths from 500-3,000 m (1,640-10,000 ft).
According to an update on the transaction provided by Evercore ISI’s Oilfield Services, Equipment & Drilling group, Eni’s decision reduces Ocean Rig’s backlog by an estimated $49 million.
Noble Drilling to stack more rigs
Noble Corp. has issued a status update for its drilling rig fleet. Last month Shell terminated theNoble Discoverer’s contract. A payment to Noble was made for the remaining term at about 90% of the operating day rate, adjusted for certain other items. The rig is being mobilized to Singapore where it is expected to be stacked.
TheNoble Sam Croftand Noble Tom Madden remain under contract with Freeport-McMoran into July 2017 and November 2017, respectively. The company has announced plans to reduce the number of rigs it uses in the US Gulf of Mexico.
As for theNoble Scott Marks, Noble Roger Lewis, Noble Joe Beall,and Noble Gene House rigs, Noble said that its Saudi Aramco contract rates were adjusted downward for 2015.
Atwood defers delivery of two ultra- deepwater drillships
Atwood Oceanics has deferred delivery of two remaining newbuilds. Last month the company entered another delay agreement to defer the deliveries of theAtwood Admiral until 2017, and the Atwood Archer until 2018. The agreement with Daewoo Shipbuilding & Marine Engineering Co. postpones the milestone payments of $93.9 million for the Admiral and $305 million for the Archer to their delivery dates in exchange for $50 million payments for each rig on Dec. 31, 2015. This deferral builds on the company’s April 2015 choice to delay rig delivery for one year to reduce its near-term capex spending in light of the challenging offshore drilling market. Atwood signed a letter of intent for one of the newbuilds to commence a drilling program offshore Brazil in 3Q 2017.
