15. A method of connecting subsea flowlines to a subsea manifold, the method comprising:
providing a first production jumper flowline for facilitating production flow from a first subsea well into the subsea manifold, having a first jumper termination apparatus connected to a subsea manifold connector of the subsea manifold and comprising a first access interface;
providing a second production jumper flowline for facilitating production flow from a second subsea well into the subsea manifold, the second production jumper flowline having a second jumper termination apparatus; and
connecting the second production jumper flowline to the subsea manifold via the first access interface of the first jumper termination apparatus and the subsea manifold connector by vertically stacking the second jumper termination apparatus on the first jumper termination apparatus.
