The XLE jack-ups
- The XLEs are the worldʼs largest jack-up rigs and are designed for year-round operation in the North Sea, in water depths up to 150 m (492 ft)
- Uptime and drilling efficiency are maximised through dual pipe handling. While one string is working in the well centre, a second string of casing, drill pipe or bottom hole assembly can be assembled/disassembled and stored in the set-back area, ready for subsequent transfer for use in the well centre thus reducing non-productive time
- The drill floor features Multi Machine Control – a fully remotely operated pipe handling system allowing all standard operations such as stand building and tripping to be conducted without personnel on the drill floor, thus ensuring a high level of consistency across crews and improved efficiency
The South Korean town of Okpo is dominated by its shipyard. And the long legs of Maersk Invincible give a commanding view of the Daewoo Shipbuilding and Marine Engineering (DSME) yard.
The world’s largest jack-up drilling rig was built in 2016 and delivered on January 4, 2017.
It is designed to meet the needs of the customer Aker BP and built-in adaptability means she can easily adjust to different work requirements. The rig can operate reliably and safely in waves of up to almost 30 metres – the height of Rio de Janeiroʼs Christ the Redeemer statue and larger than could be expected even in hurricane-force winds.
“Maersk Invincible is tailor-made for the contract, with the flexibility to reach wells that other jack-ups canʼt reach,” says Frederik Smidth, Maersk Drillingʼs Chief Technical Officer, inspecting the drillfloor as workers put the finishing touches to the rig before she sails to start a five-year contract in the tough conditions of the Norwegian North Sea.
When jacked up to her full height of more than 170 metres at the far end of the DSME yard, Maersk Invincible casts a long shadow over the neighbouring vessels and even the surrounding hills.
