Deepsea Yantai rig will drill for PGNiG again

Norwegian rig operator Odfjell Drilling has signed, on behalf of Chinese shipowner (owner) CIMC Offshore, a charter agreement with PGNiG (Orlen Group) for the Deepsea Yantai platform. PGNiG has already used this platform in the past.

PGNiG will use the semi-submersible drilling rig to drill the ‘Tomcat’ well under licence PL 1055 in the Norwegian Sea. The contract includes an option to drill two further wells in 2024. Financial information on the contract was not disclosed.

The Deepsea Yantai rig’s work for PGNiG on the ‘Tomcat’ well is scheduled to take 55 days to drill and is expected to start in late Q2/early Q3 2024.
