The application of titanium components in subsea production systems continues to increase. This is prompted by increasing depths of hydrocarbon drilling and production, and higher temperature, more aggressive well environments, all of which capitalize on lightweight,
very flexible, fatigue-resistant, and highly corrosion-resistant titanium alloy components. These titanium alloy components can and have been successfully integrated into steel offshore riser and subsea systems when certain proven design guidelines and strategies are followed.
This paper offers an overview of relevant physical, mechanical, and environmental design aspects and guidelines which help ensure successful application of titanium alloy subsea components.
