Abstract

The present invention provides a method and apparatus for connecting a flowline to a subsea structure. A flowline connection tool is deployed downwardly to the subsea structure and secured to the subsea structure. A flowline terminal head, which is at the end of a flowline, is then pulled toward the flowline connection tool by means of a pull-cable. The flowline terminal head is then secured to the subsea structure and the flowline connection tool is recovered to the surface. The flowline connection tool contains a prime mover means in order to minimize the length of cable exposed to forces encountered in pulling the flowline to the subsea structure.
