Maersk Invincible supplied from shore

Maersk Invincible is being supplied with electricity through the Valhall field. It is possibly the first time a drilling rig is being powered fully from shore.

“This is a pioneer project for Aker BP. Electrifying the drilling rig allows us to significantly cut local CO2 and NOx emissions. This is in line with our strategy of developing solutions that contribute to minimising the environmental consequences of our activities,” commented Valhall field director, Per Mikal Hauge in Aker BP.

Calculations show that electrification of the drilling rig will reduce local emissions by 15 200 tpy of CO2 and 168 t of NOX.

The new drilling rig arrived at the Valhall field in early May. During the next years, the rig will permanently plug a total of 18 wells from the Valhall DP platform.

“The Valhall field receives power from Lista through a 294 km long subsea cable. We had available power supply capacity and Maersk Drilling made a commitment to facilitate electrification of the Maersk Invincible when it was built in South Korea,” Hauge explained.

Maersk Invincible started plugging operations on the Valhall field in May. The rig receives power from the Valhall IP platform through a 500 m high-voltage cable.

Aker BP has received award of support up to NOK 42 million from the Norwegian business sector’s NOX Fund for the electrification project.

“Aker BP wants to prevent harm to the environment through energy efficiency and reducing emissions to air. With the electrification of Maersk Invincible, we are reducing our emissions even further,” Hauge concluded.
