Abstract
A flowline connection apparatus having a pivotally mounted funnel an upright frame, which is a permanent part of a subsea well installation such as a manifold or subsea production tree. The funnel rotates is rotatably mounted to rotate from a vertical position to a horizontal position. Retractable pins engage a slot in the funnel to lock the funnel in a vertical position or can be retracted to unlock the funnel, allowing the funnel to rotate to the horizontal position to engage a hub connector. A flowline end termination stabs into the funnel while the funnel is in the vertical position. The flowline termination body has a flange connector on one end that connects to a flexible flowline. The body has an annular external recess for securing the body within the funnel once in place. Pins engage the annular recess to hold the flowline end termination body in the engaged position. A mandrel is carried within an axial bore of the body for axial reciprocal movement. The body has a nose on its lower end which is tapered to facilitate entry into the funnel. The mandrel has a flowline connector hub on its downstream end that is recessed within the nose of the body while in the retracted pos…
