ABSTRACT OF THE DISCLOSURE A flowline pull-in apparatus is operable from an overhead vessel and transports flowlines to a subsea wellhead. The apparatus includes a sled disposed on the sea floor and connected to the flowlines. A two- part pull-in frame, removably positioned within the sled, is connected to the overhead vessel. The over- head vessel removes the pull-in frame and lands the frame on a wellhead. The frame is connected to the sled by means of cables. After the frame has been landed upon the wellhead, winches on the frame are hydraulically activated from the vessel and reel in the cables, thereby drawing the sled into engagement with the lower portion of frame and positioning flow- line mandrels, which project from the sled, adjacent the lower portion of the frame. The cables are thereafter cut and the upper portion of the frame is released and removed by the vessel from the lower portion. A wellhead production system is then landed on the lower portion to establish fluid communication between the flowline mandrels and the wellhead.
