The present invention provides a method and apparatus for connecting a flowline to a subsea structure. A riser and flowline connection tool are deployed downwardly to the subsea structure and a flowline terminal head, which is at the end of the flowline, is pulled to the flowline connection tool by means of a pullcable. Then the flowline terminal head is secured to the subsea structure and the flowline connection tool is recovered to the surface. The flowline terminal head consists of a connector hub to which the flowline is welded, a curved carrier pipe into which the end of the flowline is inserted, a bullnose to which the pullcable is attached, and a dovetail tenon which engages a dovetail receptacle to secure the terminal head to the subsea structure. The flowline terminal head may include buoyancy which keeps it free of difficult terrain in the vicinity of the subsea structure.
