ABSTRACT:
A subsea flowline connection system wherein a terminal connector on a flowline is pulled by a cable into a funnel on a connector base structure. The upper and lower 5 surfaces of the terminal and funnel cooperate to align the component in the vertical plane. The terminal has curved vertical sides which make only line contact with straight vertical walls in the funnel to deliberately allow limited, misalignment (.+-.6.degree.) between the components in the horizontal plane as the terminal is drawn into the funnel. Securing device is then installed between the misaligned components to lock them together in that position. A pull-in tool is provided which is lowered onto the base and includes a pull-in cable for drawing the terminal into the funnel and a device for installing the securing device which lock the components together.
