The 678ft rig will feature Keppel’s new proprietary KFELS N Plus design, and will have a maximum combined drilling load of 3,860 kips.
The new jack-up rig will be capable of operating at a maximum water depth of 500ft, drill to depths of 35,000ft and be equipped with a 100ft cantilever outreach. The jack-up will meet the stringent operating requirements for the most challenging of wells.
The rig will be equipped with 72 high-capacity pinion jacks and self-positioning fixation system of OTD’s proprietary design, for robust performance during installation and elevated survival and drilling conditions.
Following delivery in the first quarter of 2017, the jack-up rig will be deployed in the Eastern China Sea, but it will also be able to operate in the North Sea.
TS Offshore chairman Dr Xiong Shaohui said the KFELS N Plus rig is robust and cost-efficient, with distinctive safety and operational features.
"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," Shaohui said.
"We have chosen to build this unit in Singapore to meet specific customer requirements. Keppel FELS was probably the only yard able to provide us with such a high-specification rig customised to our needs, that would be well received by the market."
Keppel Offshore & Marine offshore managing director and Keppel FELS managing director Wong Kok Seng said the 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.
"It has the versatility to operate efficiently in the deeper waters of the Eastern China Sea as well as areas where the operating foundation conditions pose considerable installation challenges," Kok Seng said.
