This invention covers a subsea manifold for selectively connecting a transport line to one of a plurality of subsea production lines leading to subsea wells which are drilled in the ocean floor for the production of oil and gas. It includes a pie-shaped enclosed container with a plurality of well line inlets arranged in an arc on the inside of the container, a flow passage in the apex of the container, and a hollow flexible arm connects at one end to the flow passage and the other end is extendible to be moved from one to a selected one of the well line inlets. Due to the enclosed nature of the hollow flexible arm and enclosed arrangements, the flexible arm is not required to make a tight seal with any of the well line inlets. Individual well testing and routing of pumpdown tool (PDT) is permitted.
