Operational update concerning Deepsea Mira
At the beginning of April 2023, the Deepsea Mira departed from Bergen, Norway,
and began mobilization to the first well location in Namibia for its
multi-country contract with TotalEnergies. The rig has experienced some delays
loading equipment and performing required maintenance during the transit, and we
are now targeting commencement of the contract at the end of the second quarter.
