Marine riser, drilling riser. A string of specially designed steel pipe which extends from a drill ship or platform to the subsea wellhead. Marine risers are used to provide a return fluid-flow conductor between the well bore and the drill vessel and to guide the drill string to the wellhead on the ocean floor. The riser is made up of several sections including flexible joints and a telescoping joint to absorb the vertical motion of the ship or platform caused by wave action.
