Maersk Drilling has taken delivery of its fourth XLE jack-up rig, the Maersk Invincible, from Daewoo Shipbuilding and Marine Engineering (DSME) in South Korea.

The rig is the fourth and final rig in a series of four ultra-harsh environment jack-up rigs to enter Maersk Drilling’s fleet. The first three jack-up rigs have been delivered from the Keppel FELS shipyard.

With a leg height of 206.8 m (678 ft.),the rigs are the world’s largest jack-up rigs. They are designed for year round operation in the North Sea, in water depths up to 150 m (492 ft.).

Maersk Invincible will now mobilise to the North Sea and will in the second quarter of 2017 commence a five year firm contract with Aker BP for plug and abandonment work on the Valhall field.
