Abstract

The development of deepwater oil and gas reserves constantly faces the challenge to reduce costs of all components and activities. A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. With an increase in drilling operations in harsh environments, drilling riser requirements and limits have become more onerous due to uncertainties involved in response prediction and prolonged drilling programs. A high level of understanding is required of the response of the system to various conditions, and the design issues that govern the system. This paper presents an overview of the engineering challenges faced in designing drilling riser system for drill ship in water depths of 10,000 ft. Also, Static and dynamic analysis of drilling riser system have been carried out for the development of drilling riser joint.
