Titanium alloys have been found to provide substantial cost and operational benefits in offshore production and drilling systems. Properties such as high strength, low density, exceptional corrosion resistance, and inherent flexibility have made the alloys a viable choice for equipment including drilling risers, drill pipe, and tapered stress joints. In most cases the most successful applications will marry titanium and steel together in a hybrid fashion. This paper provides an overview of known and potential benefits of certain high-strength titanium alloys in a variety of offshore applications. The alloys are based on Ti-6Al-4V alpha-beta titanium, that have been modified for optimum performance in each application. The following applications are discussed: offshore drilling risers and drill pipes for short-radius drilling and extended-reach drilling; titanium tapered stress joints and titanium/steel hybrid risers.
