Noble Corporation (NYSE:NE) announced that it has closed its acquisition of FDR Holdings Limited (Frontier). The acquisition of Frontier, formerly an independent drilling company, and previously announced agreements with Shell increase Noble's drilling fleet size to 69 from 62 units, with the addition of three dynamically positioned drillships (including two Bully-class joint venture-owned ultra-deepwater rigs under construction), two conventionally moored drillships, including one which is Arctic-class, and a conventionally moored deepwater semisubmersible drilling rig. Additionally, as a result of this acquisition, Noble will own and operate a dynamically positioned floating production, storage, offloading vessel (FPSO).
