METHODS, SYSTEMS AND APPARATUS FOR CIRCULATING FLUID WITHIN THE ANNULUS OF A FLEXIBLE PIPE RISER
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.
