Danish rig operator Maersk Drilling has won a contract extension from Aker BP for the CJ70 XLE ultra-harsh environment jack-up rig Maersk Integrator.

Expected to commence from next September, the rig is now due to spud a well at Aker BP’s Tambar field in the southern North Sea.

The $10.9m contract excludes a potential performance bonus. The programme is expected to last for about 40 days.

The rig is contracted as part of the alliance agreement that Maersk Drilling signed with Aker BP and Halliburton in 2017.

Before it begins the drilling operation on the Tambar field, Maersk Integrator will undergo upgrades to turn it into a hybrid, low-emission rig, similar to the ones previously announced for the Maersk Intrepid.

The upgrade involves running the rig on hybrid power with low levels of nitrogen oxide (NOx) emissions, and adding data intelligence to further limit energy consumption and CO₂ levels.

Backed by support from the Norwegian NOx Fund, the programme has a separate compensation scheme signed with Aker BP.

Maersk Drilling COO Morten Kelstrup said: “We are very happy to continue our close collaboration with Aker BP, and to announce the low-emission upgrade for another XLE rig.

“The great collaborative efforts in the alliance are producing high efficiency, leading to wells drilled much faster than planned and mutual benefit for all parties involved.

“Higher efficiency in itself reduces the CO₂ emissions associated with a drilling campaign, and this aspect is now further strengthened by adding hybrid, low-emission technology.”

The Maersk Integrator is specially designed for operations in the North Sea. It is currently operating on the Ula field offshore Norway, with work expected to be completed by next July.
