Transocean also has options to build up to another five similar jackup rigs with Keppel FELS in addition to the five rigs, which are scheduled to be delivered from the first quarter of 2016 to the third quarter of 2017.
Keppel O&M offshore managing director Wong Kok Seng said the company, earlier in 2013, had already delivered three jackup rigs to Transocean.
"We are glad that Transocean has chosen to expand their fleet of premium jackup rigs with the KFELS Super B Class design," Seng added.
KFELS Super B Class rigs have been tailored to suit Transocean’s requirements and are designed to operate in 400ft of water depth and drill to 35,000ft.
Equipped with good horsepower during drilling operations, the rig has a two million pound drilling system and a maximum combined cantilever load of 3,700 kips.
The rig, which can drill at a 75ft outreach, will also be installed with offline stand building features in its drilling system package, allowing drilling and preparation of drill pipes to take place simultaneously.
The company’s other projects include upgrades and conversions of the Sedco 700-series semisubmersibles to enable better positioning, and the repair of various Transocean rigs.
In 2013, Keppel O&M has secured 20 newbuild projects, worth about S$6.4bn, including the latest order from Transocean.
Keppel FELS, which has already delivered 17 rigs in 2013, is on track to complete 20 or even 21 rigs by the year’s end.
