Aker BP has received consent to use the Mærsk Invincible jackup rig for plugging and abandoning wells at the Valhall field.
Production from the Valhall DP is scheduled to end in the next few years. Three of the wells are still in production, while 18 have been shut down. Of these, 13 have been permanently plugged and abandoned, and Maersk Invincible will be used for plugging the other five.
Maersk Invincible is owned by Maersk Drilling, was delivered by the Daewoo yard in South Korea in 2016, and is classified by DNV GL and registered in Singapore.
Valhall is in the far south of the Norwegian sector of the North Sea, about 340km south-west of Stavanger. The field has been developed using six fixed steel-jacketed facilities with bridge connections. Water depth is about 70m. Production began in 1982.
