Abstract
A pipeline branch arrangement that forms a piggable-Y at the intersection with the trunkline and is oriented vertically relative to the trunkline. The approach piping to all legs of the piggable-Y are configured to incorporate 3D bend or larger radii as required. This arrangement permits the passage of foam pigs, hard pigs, and smart pigs. Rotation of the piggable-Y to the vertical plane configures all of the branch piping in the vertical plane, which permits the support sled width for pipe laying to be kept to a minimum. The arrangement of the 3D bends fore and aft of the piggable-Y aligns the trunkline ends in a co-linear manner. This permits the configuration to be installed by conventional S-Lay techniques.
