Keppel Offshore & Marine’s wholly owned subsidiary Keppel FELS will build a jackup rig worth approximately $500m for TS Offshore.

Set to be deployed in the eastern China Sea upon delivery scheduled in the first quarter of 2017, the rig will be the first jackup built to Keppel’s new KFELS N Plus design and is equipped with 72 high-capacity pinion jacks and self-positioning fixation system.

The KFELS N Plus has a leg measuring 678ft or 68 storeys tall, and a maximum combined drilling load of 3,860kips with an ability to meet stringent operating requirements for challenging wells.

Equipped with a 100ft cantilever outreach, the jackup can work at a maximum water depth of 500ft and drill to depths of 35,000ft.

TS Offshore chairman Dr Xiong Shaohui said: "It is one of the world’s most advanced rigs of its class with better drilling capabilities, a superior cantilever load performance, a larger deck space, a higher variable load and enhanced accommodations.

"We are confident it fills the gap for ultra-high specification rigs needed in the eastern China Sea or almost anywhere in the world with a need for high-specification and deepwater jackup rigs."

Keppel’s R&D arm, Offshore Technology Development (OTD), has developed the KFELS N Plus jackup, which is said to be an enhancement of the company’s KFELS N-Class design.

The KFELS N Plus design offers better performance during installation, as well as elevated survival and drilling conditions.

Keppel Offshore & Marine offshore managing director Wong Kok Seng said: "This rig is the combination of Keppel’s unique experience in designing and building rigs both for the North Sea as well as other parts of the world."
