摘要： Disclosed are methods, systems and apparatus for circulating fluid within the annulus of a flexible pipe used in a riser in an offshore hydrocarbon production facility. Fluid, such corrosion inhibitors, can be introduced into the annulus by pumping fluid from a storage tank located on a platform or vessel into tubes within the annulus. Use of the system to flow the fluid through the annulus can prevent or reduce corrosion of the steel members within the annulus and increase the fatigue life of the riser.

摘要： A method for installing a subsea flowline and riser assembly on a sea floor includes providing a flowline having an axis and an end connected to a hinge-over joint, and a riser having an axis and an end connected to the joint such that the axes of the riser and flowline extend substantially parallel. An end of the flowline opposite the joint is lowered to the sea floor. The end of the flowline connected to the joint is lowered to the sea floor. The joint is connected to a foundation that is installed in the sea floor. The riser is rotated about the hinge-over joint such that the riser axis is substantially perpendicular to the flowline axis. A subsea jumper is connected between an opening formed in the flowline and an opening formed in the riser so that the riser is in fluid communication with the flowline.
