Houston-based oil and gas E&P firm Noble Energy is being sued by Switzerland-based offshore drilling giant Transocean for patent infringement in the case of five of Noble’s drillships.
The case has been filed in a Houston court.
Transocean claims the five vessels – Bob Douglas, Don Taylor, Globetrotter 1, Sam Croft and Tom Madden – used so-called “dual-activity” technology that Transocean had patented in 2004.
The technology delivers time savings of between 20% and 40% on a drilling project.
Noble says it will contest the claim.
