Keppel FELS delivers the jackup rig 'UMW Naga 4' to UMW Oil & Gas Corporation in Singapore. The rig was completed five days ahead of schedule, on budget and with a perfect safety record. UMW Naga 4 is the fourth consecutive rig that Keppel FELS has delivered ahead of schedule this year. UMW Naga 4 is built to Keppel’s proprietary KFELS B Class design which is today the industry standard for modern jackup rigs. With another 16 KFELS B Class/Super B Class rigs on order, it reflects the strong market demand for the design.
