The benefits from using threaded connectors for flowlines with installation from a drilling vessel have already been identified and documented within the industry. Threaded riser use however is currently generally limited to Spars and TLP’s. The possible reasons for the lack of adoption of threaded risers are discussed. Recent improvements in connector design and new threaded riser concepts are highlighted together with their advantages. Using threaded connectors for risers as well as flowlines, conductors, tubing, and casing could allow the majority of field hardware to be installed from drilling vessels, giving substantial cost savings and field development flexibility. The challenge is to bring together those responsible for drilling and production to jointly develop all field architecture.
