Abstract
A flowline for hydrocarbon which is capable of being reeled and which is unreeled for being laid on the seabed using the reeled lay method is comprised of successive pipe sections having opposing ends which are joined by an anchor collar that is butt welded to the opposing ends. The pipe sections have a jacket on the exterior of the pipe sections, but the pipe sections are able to be reeled. Anchor collars are affixed by butt welding between the ends of adjacent pipe sections. Each anchor collar has a fixture or protrusion radially outward which has an outer diameter less than or at least not more than the outer diameter of the pipe section jacket. The flowline has the same inner diameter at the pipe sections and the collar, and the pipe has the same outer diameter as the collar, while the protrusion protrudes outward from the exterior of the collar. The flowline is anchored on the seabed by unreeling it from a spool, applying a clamp to the collar before delivering it to the seabed, and anchoring the clamp to the seabed. The jacket may expose the fixture or protrusion or may initially cover it and be removed to enable the clamping.
