The ultra high-specification jack-up rig has been designed for the harsh environmental conditions of the North Sea (U.K. Sector). Its enhanced leg design incorporates Keppel's proven and reliable high capacity rack and pinion jacking system which ensures that the rig is able to jack up and stand firm in a secure and safe manner even in challenging environments.

Mr. Wong Kok Seng, Managing Director (Offshore), Keppel Offshore & Marine and Managing Director, Keppel FELS said, "In developing the KFELS Super A Class, we have brought together the winning features of our proven jack-up rig designs to provide operators with a robust and cost-effective drilling rig for harsh environments and cold climate areas. We are pleased that Discovery Offshore has selected this design for their first two harsh environment rigs.

"Although it is a new design, our expertise and strong engineering, construction and project management experience has enabled us to deliver it ahead of schedule while achieving an excellent safety record. We look forward to delivering the second KFELS Super A Class to Discovery Offshore just as efficiently."

Developed by Keppel FELS' R&D arm, Offshore Technology Development (OTD), the KFELS Super A Class is an enhancement of the successful and proven KFELS A Class design.

Discovery Triumph has been customized to meet the requirements of Discovery Offshore and is capable of operating in water depths of 400 ft and drilling depths of 35,000 ft.

"With the strong demand for rigs capable of working in the North Sea, we believe the KFELS Super A Class is a value proposition rig with leading performance compared to ultra high specification jack-ups of its class," said Mr John T. Rynd, CEO of Hercules Offshore.

"With the strong demand for rigs capable of working in the North Sea, we believe the KFELS Super A Class is a value proposition rig with leading performance compared to ultra high specification jack-ups of its class. It provides higher variable load, better drilling capabilities, better cantilever load performance and a larger deck space. Keppel-designed rigs have a strong track record of being industry benchmarks and we are confident that Discovery Triumph will be just as successful and exceed the expectations and requirements of all our customers.

"As this North Sea-compliant rig is able to operate efficiently in virtually all parts of the world outside Norway and the Arctic, we also see many opportunities for it to be deployed in other parts of the world to generate maximum utilization. With another KFELS Super A Class rig about to join Discovery Triumph later this year, we are well positioned to become a strong player in harsh environment drilling."

Keppel FELS is currently building another KFELS Super A Class jack-up rig for Discovery Offshore as well as a further three for Ensco.

For greater operational safety, the KFELS Super A Class is equipped with state-of-the-art pinion overload detection, rack phase difference detection, and brake failure and overload protection devices. In addition to having strong drilling capabilities and cantilever load performance, the KFELS Super A Class has a two million pound hook load drilling system and includes a spacious deck and amenities to accommodate 150 people.
