COPENHAGEN, Denmark – Maersk Drilling has taken delivery of its fourth XLE jackup rig, the Maersk Invincible, from Daewoo Shipbuilding and Marine Engineering in South Korea.
In 2Q 2017, the Maersk Invincible will begin a five-year firm contract with Aker BP for P&A work on the Valhall field in the Norwegian North Sea.
This is the fourth and final rig in a series of four ultra-harsh environment jackup rigs to enter Maersk Drilling’s fleet. The Keppel FELS shipyard delivered the first three.
With a leg length of 206.8 m (678 ft), the rigs said to be the world’s largest jackup rigs and are designed for year round operation in the North Sea, in water depths up to 150 m (492 ft.).
Maersk says the uptime and drilling efficiency are maximized through dual pipe handling. While one string is working in the wellbore, a second string of e.g. casing, drill pipe or bottomhole assembly can be assembled/disassembled and stored in the set-back area, ready for subsequent transfer for use in the wellbore thus reducing the non-productive time.
The drill floor features Multi Machine Control - a fully remote operated pipe handling system allowing all standard operations such as stand building and tripping to be conducted without personnel on the drill floor.
