Steel catenary riser
A Steel catenary riser (SCR) is a common method of attaching an offshore pipeline to a deepwater floating oil production platform. The pipeline is extended into a flexible pipeline up to a catenary on the production platform.  The risers are typically 8-12 inches in diameter and operate at a pressure of 2000-5000 psi.
They were first used by Shell on the Auger tension leg platform in 1994 which was moored in 872 m off water.
