A lawsuit filed by Transocean in Houston on 16 January claims dual-activity drilling packages on drillships Noble Bob Douglas, Noble Don Taylor, Noble Globetrotter I, Noble Sam Croft and Noble Tom Madden are too similar to a technology Transocean pioneered in the late 1990s and later patented.
Transocean claims Noble “willfully committed acts of infringement” in building and deploying the rigs.
