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.

Abstract: The disclosure provides a system and method for installing subsea equipment, such as a pipeline and equipment associated therewith in a target area, generally having restricted overhead access. An anchor can be installed in the seabed and can include one or more sheaves. A pipeline can be provided, which can include related equipment and/or one or more coupling devices situated remotely from the anchor relative to the target area. A winch wire can be provided and is adapted to be directly or indirectly coupled across at least a portion of the target area to the pipeline. A transfer sling having a pull wire and an initiation wire can be coupled between the winch wire and pipeline to assist the winch wire pulling the pipeline into the target area and transferring a pipeline force from the sheave to the anchor independent of the sheave.
